The goal is to arrange the pieces in some simple configuration such that their features respect a given rule (or rules)  form a pattern  occasionally but not typically enforced by mechanical means. For example, "piece features at specific points (e.g. edges or corners) match (or complement, or dismatch) those at corresponding points on abutting pieces" or "the heights (or numeric values) of aligned pieces total a specific constant" or "defined sets of faces have all distinct (or equal) features." Sometimes, as in the case of matchstick puzzles or the "Eight Queens" puzzle, the individual pieces are indistinguishable, but their arrangement in a particular pattern is paramount.
Unlike with Assembly puzzles, laying the pieces out or into a tray, or stacking them together to form a particular shape, is not the primary focus, though it might contribute to the difficulty  it is the pattern rule which provides the chief challenge. Success is usually determined by careful inspection, checking to see that the given rule has been everywhere satisfied.
You might see some puzzles in this section that remind you of jigsaw puzzles  but the key difference here is that the edge features are compatible with several other potential mates and there are usually several other pieces that match any given piece. The individual pieces can be easily arranged in many different ways that partially satisfy the rule  but overall there is usually only one total arrangement (or a relatively small number among all possible arrangements) that will completely meet the goal. Finding a solution within a huge range of possibilities can be very hard, and this class is often attacked using computers  but beware, the class of edgematching puzzles is NPComplete . You can read more on this topic in Erik and Martin Demaine's 2007 paper Jigsaw Puzzles, Edge Matching, and Polyomino Packing: Connections and Complexity ( download a PDF here ).
Jacques Haubrich published his definitive Compendium of Card Matching Puzzles in three volumes, in which he describes over 1000 puzzles, and a companion volume called About, Beyond, and Behind Card Matching Puzzles in which he provides interesting theoretical and historical analyses. According to Haubrich, and to Slocum and Botermans in their 1986 book Puzzles Old and New, the first edgematching puzzle patent was applied for in 1880 by Edwin Lajette Thurston of Cleveland, Ohio (b.1857 in MA, d.1921) and granted in 1892  see 487797 and 487798; also see 1893's 490689. Thurston was, of all things, a patent attorney! For a precursor to the edgematching puzzle, using triangular tiles like "Triominoes," see U.S. Patent 331652  Richards 1885. Richards doesn't claim the triangular form of the dominoes, but rather the ways to make and mark them. He never uses the word "puzzle"  he describes a number of games but none come close to being a puzzle.
In Hoffmann's 1893 Puzzles Old and New, the only edgematching type puzzles mentioned are #72 in chapter IV "The Royal Aquarium Thirteen Puzzle" (equivalent to the French Le Nombre Treize), and #18 in chapter III "The Endless Chain" (equivalent to the French La Chaine sans Fin).
Major Percy Alexander MacMahon and his friend Major Julian R. Jocelyn applied for a patent in Great Britian in 1892 (#3297  I could not find a copy online  it is reproduced in Haubrich's About,...) in which they describe several triangular tile games and puzzles. In his 1921 book New Mathematical Pastimes, MacMahon published some of the first material to treat edgematching puzzles with mathematical rigor. That work also discusses his 3D puzzle Colored Cubes, first introduced in a lecture he gave in 1893.
Tilelaying puzzles (in German, "Legespiel") of both the edgematching and polyform varieties have been explored and produced by Kate Jones at Kadon, and you can read a lot of interesting material at the Kadon site  see Edgematching Colors and Shapes, and More About Edgematching. You can see Erich Freidmann's collection here. You can see some original designs by Yukio Hirose here. Take a look at George Hart's article "A ColorMatching Dissection of the Rhombic Enneacontahedron." Also see Peter Esser's page. And Toby Gottfried's site.
Jacques suggests the following seven categories:



Jacques also defines a classification scheme by which one can identify the puzzles abstractly and find isomorphisms (i.e. equivalent puzzles).
Jacques' conclusions, based on computer analysis, regarding the best approach to solving these puzzles agree with my empirical findings  in general, fix the tile in the middle and work around it. A good tile to choose for this middle position is the tile with the most possible matches.
As discussed in my polyforms section, the only regular polygons which can be used to completely tile the plane are the equilateral triangle, the square, and the hexagon. It is evident in Haubrich's Compendium that these shapes comprise the majority of tile shapes used in existing edgematching puzzles. Rectangles have also been used, as have octagons (allowing empty areas). I've organized my example puzzles by tile shape:
[Square Tiles]  [Hexagonal Tiles]  [Triangular Tiles]  [Other Tiles] 
Some puzzles have tiled surfaces other than a plane  e.g. the platonic solids, or a cylinder. I would file such things under 3D edgematching puzzles.
The Thurston design was used by Calumet ca. 1930 as advertising for their products. In the Calumet Puzzle, one must match not just the proper color edges, but also the corresponding top and bottom halves of the baking powder cans. I solved the Calumet puzzle using a variant of my Drive Ya Nuts technique. 
The Grandpa's Wonder Soap Puzzle was patented (U.S. Patent 1006878) in 1911 by A.K. Rankin. It is described on page 36 of Slocum and Botermans' "Puzzles Old & New." The goal is to form a 3x3 grid such that at the points where the quartercircles on the corners of the tiles meet (either four or two), there are always different colors on each of the meeting quartercircles. Grandpa's head must always be upright on every card, so the cards cannot be rotated. Jacques says this is the first example of a corner dismatching puzzle. There are different versions. 
The Besco Soap Puzzle  from the Beaver Soap Company of Dayton Ohio. Form a 3x3 grid such that there are four different colors in each circle at the corners, and two different colors in each halfcircle. There must also be a different color at each of the four corners of the grid. The pieces must all remain oriented with the words "Besco Soap" upright. JH Vol.2 p163 2 solns 
Le Berger Malin  The Lazy Shepherd (N.K. Atlas Paris circa 1910). NOTE: "malin" can also be translated as "ingenious." There are nine tiles, each of which is divided into four quadrants by two diagonals. There is a number in each quadrant, and the corresponding number of sheep are depicted. Arrange the tiles in a 3x3 grid such that the total in each square formed where edges meet totals 10. According to Jacques, this is the first known example of a Heads/Tails puzzle (the two numbers which must add to ten comprising the head and tail). 
Le Fermier Avise  The Wise Farmer The same principle as the Lazy Shepherd, except with chickens and now it's a wise farmer. 
This is a French puzzle (CasseTete) called "Le Nombre Treize"  The Number Thirteen. Arrange the tiles in a 3x3 square such that the red figures align vertically and the blue figures align horizontally, and such that the three figures in each of the six rows and six columns add to 13.

The Ultimate Puzzle (4x4 square tiles)
The Ultimate Puzzle Two (3x3 right triangle tiles) Both designed by Lee Willcott of Estonia. The original version has square tiles  each side has a cutout or tab, in one of four shapes: an "in" arrow, an "out" arrow, a cross, or an oval. There are four challenges: build a 2x2; build a 3x3 (find 9 tiles that work); build a 4x4 with no sideup constraint; build a 4x4 with either all smooth sides or all rough sides up. The Ultimate Puzzle Two has 18 righttriangular tiles, pairs of which form squares. Nine squares must be arranged in a 3x3 grid (so I have listed it here in the square tiles section with the original version). Each tile has a cutout on each side  the cutouts form halves of four symbols: crown, heart, spade, and star. On one pair of tiles, a heart on the diagonal is offset  the bumps half is lower and the v half is deeper. Where tiles touch the halves must form a whole symbol, so this is a "heads and tails" type edgematching puzzle.

The Enigma (a dodecahedral edgematching puzzle) by Reiss, 1971 
Colin James sent me a rare Twitchit puzzle, issued in 1972 by the Hubley Division of Gabriel Industries of Lancaster PA, and designed by Piet Hein. This is a dodecahedron whose faces turn. One of three symbols (a circle, square, or triangle) is printed at every vertex of every pentagonal face. The objective of the puzzle is to rotate the faces (in place) so that at all 20 vertices of the dodecahedron, three different symbols show. Although discolored with age, the plastic remains intact and the puzzle is playable. I solved it! Thanks very much, Colin! 
I obtained a copy of the Hubley Toys 1972 Catalog, which features a series of four puzzles designed by Piet Hein. With the acquisition of the Twitchit, I now have an example of each of these vintage Piet Hein puzzles. 
Using this technique I can prove fairly easily that this puzzle has only one distinct solution.
There are seven hexagonal "nuts" that I label A thru G. For each nut, the six sides are numbered 1 through 6 in some order. The numbering scheme of each nut, starting with 1 and proceeding CLOCKWISE, along with the letter ID I arbitrarily assign the nut, is shown below:
All nuts must be used, each once and only once. One nut of seven must be placed in the center. In a solution, each nut except for the center must abut 3 other nuts and at each abutment the numbers assigned to the respective abutting sides must match.
When a central nut is chosen, the remaining nuts must be arranged around it. For any side of the central nut, the orientation of each remaining nut that can abut this side is given by the cell in the apropos row and column of the primary table. The row corresponding to the central nut is eliminated from consideration (indicated by the green line through it). If we rearrange the columns to correspond with the CLOCKWISE side numbering of the central nut (and repeat the "1" column last, for convenience in analysis), we arrive at the 7 diagrams shown below.
Some reflection should convince you that a solution is possible if and only if one can find a set of six cells, such that:
When A is in the center there is no solution possible. Consider nut G. Its 1 cannot be used to abut the central 1 on A, since there can be no nut clockwise from it that matches its 6 while also matching the central 6 required at that position. Hence cell G1 crossed out with line a. G cannot be used to abut the central 6 since there can be no nut counterclockwise from it that matches its 1 while also matching the central 1 required at that position. Hence cell G6 crossed out with line b. Similar arguments apply resulting in the cell in every column of row G being crossed out. This means that G cannot be used, violating rule (1) and proving that nut A cannot be used in the center.
On to nut B in the center. No nut fits counterclockwise of C5, D5, E5 or G5. No nut fits clockwise of A5, or G2. This leaves only nut F possible to abut the central 5, but nothing remains to fit clockwise of it (only another copy of the F nut would fit). This proves that nut B cannot be in the center.
Here, G6 is eliminated  nothing fits counterclockwise of it. This in turn eliminates D4 and G4. Nothing fits clockwise of A4 or E4, or counterclockwise of F4. This leaves only nut B possible to abut the central 4, but nothing remains to fit counterclockwise of it (only another copy of the B nut would fit). This proves that nut C cannot be in the center.
If you logically eliminate all impossible cells from the table when D is in the center, you find a single solution indicated by the six cells circled in blue. This is the only solution to the Drive Ya Nuts puzzle.
When E is in the center, only A can abut the central 1. This then requires C4, but no nut fits counterclockwise from it.
Nothing fits clockwise of G1 (except G again). Nothing fits clockwise of A4, B4 or G4. Since G1 is eliminated, now nothing fits clockwise of D4 or E4. This leaves only C4 but nothing fits counterclockwise of it.
Lastly we tackle G in the center. Nothing fits counterclockwise of B2, A3, C3, D3, or E3. Since B2 is eliminated, nothing fits counterclockwise of F3 either. This leaves only B3 but nothing fits clockwise of it.

The Diamond Dilemma puzzle was Copyright by Price Stern Sloan Limited in 1989, and offered prizes for solutions of various complexity. The instructions tell you to "arrange the playing pieces on the diamond so that a continuous unbroken line is formed." 
This is Dice Dominoes. The box says "Made in U.K." but there's no other provenance. There are twelve cubes, each side of which shows a correctly linked arrangement of two or three dominoes. Paraphrasing from the instructions: Using the box base as the playing area, start with a doublesix in the top left corner. (There are six faces among four of the cubes showing a doublesix.) The box holds a rectangle of 3x4 cubes. Match dice so a continuous pattern is formed, as in regular dominoes. You must use all 28 dominoes and cannot use any domino more than once. Each must line up and doubles must be at right angles. A solution sheet (I haven't looked) is enclosed.

String Octet Designed by Goh Pit Khiam, made by Walter Hoppe. Purchased from Walter at IPP 29 in SF. 8 1x2 tiles encompassing all the ways a tab and a notch can be arranged, each with a path inscribed connecting the tab and notch. Two 1x1 tiles, one with a notch and one with a tab  the start and end tiles respectively. A 4x5 tray. A sheet with 13 challenges  each specifies positions and orientations for the start and end tiles. The objective is to connect the 1x2 tiles in the tray to create an unbroken path from start to end. I really like this one! 
World Passport, from SmartZone Games. Designed by Tzafrir Kazula. Purchased at Eureka. Fit six polyhex pieces into a hexagonal grid overlaid on a "country" card such that five points are connected in order by a transparent path, with no backtracking. 

Troy Extra Muros from Smart Games, designed by Raf Peeters. I really like this one! A series of challenge cards indicate the placement of up to 4 blue and 4 red soldiers. Place the four wall pieces such that all blue soldiers are completely enclosed and all red soldiers are "outside" the walls ("Extra Muros"). (You are finding the route the walls must take.) Raf gave an interesting talk at IPP31 in Berlin, in which he said that one goal of design is to ensure a customer can apprehend the goal of a puzzle just by looking at it in the package. He achieved that in this case  I could tell what the goal was despite the fact that I found this in Québec City and this box was printed in French!

Eight sliding blocks representing walls, hallways, and stairs in various configurations, and a player figure. Set up the blocks and figure per the current challenge, then try to solve it by sliding the blocks and moving the figure from block to block to eventually exit the board. The block where the figure resides cannot be moved, and the figure can only be moved to rest on certain blocks. Temple Trap combines a slidingpiece puzzle with routebuilding challenges and has a great theme reminiscent of Indiana Jones.

This category requires you to arrange the pieces to satisfy some rule or goal relating to a pattern/silhouette the pieces make. There is no physical mechanism to restrict moves  only rules or the goal govern legal combinations. The piece shapes will be fairly abstract but usually it will be easy to abut them and they will interchange positions easily.
Note: I have created a separate page for Tangrams.

This is a vintage WeaveOGram puzzle, copyright 1951 by EdcraftCentury. See US Patent 2439583  awarded to Israel Shamah of London on Apr. 13, 1948.
From the patent description  the WeaveOGram "comprises a framework and a plurality" (patent lawyers love that term) "of flexible bands some extending in one direction and the others at right angles thereto, the various bands being interwoven... and each being capable of relative movement. On each band there is provided a number of sections of a picture... by relative adjustment of the individual bands the various sections of the picture may be juxtaposed so that a complete picture is formed. Each band will be provided with the sections of a number of different pictures so that a number of different complete pictures may be made up."
My copy allows one to make six different circus scenes. The bands move pretty freely, occasionally catching on small rough edges or tears. It is best to use both hands to move a band, slowly, from both edges of the frame simultaneously. As you might expect, WeaveOGram is not too challenging, however the graphics are nice and this is a great implementation of one of those ideas that seems obvious once you've seen it done.
Also see the earlier US Patent 1903226 awarded to Harry Lawson Perry of Jamaica, New York on Mar. 28 1933. Perry's device employs linear strips rather than looped bands.
Then see the later US Patent 3235262  awarded to Ernest Frankl of Middleboro, MA on Feb. 15, 1966. It is pretty much a copy of Shamah's idea  Frankl's improvements are to "effect economies of manufacture and assembly and to provide for ease of manipulation and attractiveness." Frankl assigned his patent to WinthropAtkins Co. Inc. of Middleboro MA, a printing company now owned by Chilcote Co. of Ohio.
From the book Classic Century Powerboats by Frank, Trudi, and Paul Miklos copyright 2002, published by MBI Publishing Company of St. Paul MN. I learned that the company Century (as of March 2012 purchased by Allcraft Marine) makes powerboats, and was founded in Milwaukee in 1926. In 1948, F. L. "Ted" Hewitt Jr. became president. Since boat production orders were seasonal  heavy from March through July and slack during the rest of the year, one of Hewitt's initiatives was to offset the downtimes by producing other, stable products such as toys. Century produced a line of educational toys under the brand Edcraft, including WeaveOGram.
Shamah also patented (in the UK) a locking mechanism for a money box.




The Frustr8tor From my friends at Puzzlemaster.ca  thanks, guys! 28 versions of the 8 Queens to solve. The front side shows an 8x8 grid. The back side has 8 tracks corresponding to the 8 columns of the grid. Along each track, each of the 8 row positions is marked by a number from 1 to 28  some appear three times, some two. One red and one green tab ride in each track  green at the top and red below. To try a puzzle, choose a number and set a red tab at every position marked by that number. Then, using the green tabs in the remaining six columns, fill in the grid according to the usual rules  a dot appears in the grid on the front at the position where a tab is set. 
This vintage French boxed version called "Jeu des Manifestants" uses 8 tiles, and is available in two versions with either triangular or rectangular tiles. Jeu des Manifestants is shown in Slocum and Botermans' "Puzzles Old & New" on page 37. For another version using battleships, see U.S. Patent 1151615  Reibstein 1915. 

Lots O Spots by Peterson  "an L. J. Gordon creation." 16 tiles, each divided into four quadrants, and with 1 or 2 spots on each. When the tile are arranged in a 4x4 grid, the quadrants define 8 rows and 8 columns. The spots come in three colors  red, purple, and green  and are distributed so that there are 8 of each color. In the hardest of four challenges, you must arrange the tiles in a 4x4 grid such that all rows, columns, main diagonals, and all short diagonals contain no more than one spot of each color. This amounts to solving the 8 queens problem simultaneously for 3 colors of queens. 
The Schpotz puzzle by Peterson Games. Arrange the nine tiles in a 3x3 grid such that every row, column, and main diagonal contains exactly three spots. 
This is Out of Line by Crisloid Plastics of Providence RI. The objective is to arrange the eight pegs in the 8x8 grid so that no more than one peg is in any row, column, or diagonal. In addition, at least one peg must be in each of the five differently shaded areas  one of the areas is a single position at the lower right corner. The cover shows a motorcycle gang  I think they're supposed to be "out of line." 

HooDoo from Tryne, circa 1955. An 8x8 board, with inner nested 4x4 and 6x6 areas marked off. 64 pegs, 8 each of 8 different colors, and two extra "neutral" pegs. There seem to have been at least two different sets of instructions issued with this puzzle.
The first two challenges cited on the first instructions, on the 4x4 and 6x6 grids, are easy since you can use more than 4 and 6 colors respectively. However, the 8x8 challenge amounts to superimposing 8 solutions of the 8 queens problem, and is impossible! This puzzle is interesting because it requires superposition, and also because it seems to be one of those rare instances where prize money is offered for an impossible challenge.




The Pin and Dot puzzle  "Insert six pins, each in a separate dot, so that no two pins shall be on the same line." This is equivalent to a sixqueens puzzle. (I don't have this  shown for reference.) 
The sixqueens puzzle has only one unique solution.
Since that solution is 180degree symmetric, it has only four rotations and reflections.

La Strategie des Nippons, Strategie des Boers, and Nouvelle Strategie These vintage French boxed puzzles are all instances of the sixqueens puzzle. (I don't have these  shown for reference.) 

Jeu des Sentinelles "A police chief represented by the red piece, with 7 sentinels represented by the white pieces, must position himself and his sentinels so that no man can see any of the other men along any straight vertical, horizontal, or diagonal line." This vintage French boxed puzzle is an instance of the eightqueens puzzle. (I don't have this  shown for reference.) 
L'Intraitable  "The Intractable" Given a 6x6 grid and 24 tokens  six each of four colors, arrange the tokens on the grid so that no horizontal, vertical, or diagonal line contains more than one token of the same color. This vintage French boxed puzzle is an instance of a superposition of four sixqueens puzzles. (I don't have this  shown for reference.) The four rotations and reflections of the sixqueens solution can be superimposed:

L'Embarras du Brigadier and L'Embarras du Caporal Given a 5x7 grid of points and 12 men, arrange the men on the grid to form six rows with four men in each row. Both of these vintage French boxed puzzles are instances of, using Singmaster's notation, a (12,6,4) configuration problem. (I don't have these  shown for reference.) Singmaster cites several appearances of the (12,6,4) problem, including in The Sociable of 1858 (as Problem 26, The Gardener's Puzzle), The Book of 500 Curious Puzzles of 1859, and Hoffmann (1893) Chapter VI, No. V.
There is a second solution (see The Sociable, or Hoffmann), but it does not fit on the 5x7 grid. Note that some (a,b,c) configuration solutions rely on the trick of stacking more than one token at a given point. 

The FiveQueens puzzle has only two unique solutions.
The asymmetric solution has eight rotations and reflections. The symmetric solution has only two, giving a total of 10. A selection of five can be superimposed.

The SevenQueens puzzle has six unique solutions, and 40 rotations/reflections.

SafeCracker 50  a reproduction of a classic design style, from Dave Janelle at Creative CraftHouse. Thanks very much, Dave! Arrange the five layers so that the five numbers appearing in each of the 16 radial columns total 50. There are many vintage paper/cardboard puzzles using this theme  Dave's is made from lasercut wood and is far sturdier. With the base plate and four additional movable disks, there are 65,536 combinations to try! 
This "SafeCracker" type of puzzle was the subject of U.S. patent 993581, granted to H. Davidson in 1911. But, see below for versions with earlier dates... 
The Davidson patent seems to have been applied to the "Great Burglar Puzzle"
which requires columns to
total 40. You can see the reference to the patent near the center.
(I don't have this.)
Even earlier, the Hegger's Century Puzzle says "Patent applied for, Copyright 1891 by G. A. Bobrick, New York." (I don't have this puzzle.) G. might stand for Gabriel, since he holds other patents from the late 19th century. Unfortunately I could not find a patent pertaining to the puzzle. While the USPTO website does allow searching for applications (as opposed to granted patents), the database only contains records from 2001 onwards. The USPTO allows one to search for granted patents from 1790 through 1975 but only by issue date, patent number, and current U.S. classification.


For reference, here are several more vintage "SafeCracker"type puzzles (I don't have these):
The White Sewing Machine Sixty Puzzle says "Copyrighted by A. L. Vandyke 1890." There doesn't seem to be a date on "The Great '51' Puzzle."
Note the swastikas that appear on the Huntley & Palmers puzzle  the symbol actually means "that which is associated with wellbeing" so this likely predates WWII and the darker usage of the symbol and was probably issued somewhere in the period from 1841 (when Palmers joined Huntley) to 1920 (when the Nazis rose to power). The "Capture UBoat 40" puzzle, however, obviously comes from the WWII period. It was manufactured by the Geiger Bros., Newark N.J. The following photos are from Jerry Slocum's collection, courtesy, The Lilly Library, Indiana University, Bloomington, Indiana. They can be found under classification section 1.3, Miscellaneous PutTogether.
"The Jayne Problem" is Copyright 1906 by George H. Vickers. I don't know what is on the back of the Leinbach puzzle (another sumto40 type) or the "Safe Combination Puzzle" (make all 12 columns sum to 55), but their fronts display no dates.
The Hecker's puzzle says "Pat. applied for" and "Since 1840" so probably dates post 1840, but displays no other info and I don't know what the back might say. The Steinfeld puzzle says "Pat. June 20th, 1882"  with a bit of research I found that the patent in question is US259920 issued to William H. Reiff of Philadelphia on June 20, 1882. That makes this the oldest version as far as I know.

the Word Wheel. Thanks for the copy, Dave!

Leonard Euler (17071783) studied Latin Squares in the late eighteenth century, and research into them has continued, not simply because of their use as puzzles, but more for their application to experimental designs and cryptography.
The enumeration of Latin Squares has not been easy  figures up to order 10 are summarized in the table below. A reduced or standard Latin Square is one where the symbols in the first row and the first column are in lexicographical order. Given the number of reduced squares, R_{n}, the number of distinct squares L_{n} is:
L_{n} = n!(n1)!R_{n}
Order n  Enumerator(s) Year

In 1992, in Discrete Mathematics, J. Shao and W. Wei published a formula for the number of Latin Squares of any order. (It is nontrivial to specify.)
The Safari Puzzle by the German company "Pussy" or "Pussycat." A 7x7 Latin Square puzzle presented as a slidingpiece puzzle. Arrange the pieces (7 each of a Hippo, Lion, Elephant, Rhino, Giraffe, Zebra, and Tree) so that only one of each appears in each row and column. 
More Madness by Parker  The Fun and Game Name. No Date. It comes as a single 5x5 plastic sheet, scored with grooves along which you are to break apart the pieces. Each square is one of five colors  yellow, red, blue, green, or white. The unbroken sheet shows the solution  this is a Latin Square puzzle and in the grid, no color occurs more than once in each row or column. There are nine pieces  two are 1x2, seven are 1x3. 
Bird's Puzzle, by Chad Valley. The Bird's Puzzle is very similar to the More Madness puzzle. There are nine pieces, two 1x2 and seven 1x3, colored with five colors  yellow, red, blue, green, and a Bird's logo  to be arranged into a 5x5 grid such that no color appears more than once in each row and column.

Utopia issued by Popular Playthings 2009 invented by Sjaak Griffioen Sixteen "buildings"  four each of four different heights. Place on the 4x4 grid according to rules and hints given on 50 challenge cards divided into 25 Phase 1 and 25 Phase 2. I enjoyed Phase 1 but Phase 2 seems overly confusing. (NOTE: this may seem to belong in the GraecoLatin section, but notice that all buildings of the same height are the same color, so height is really the only differentiator.) 
The Thirtysix Officers Problem goes as follows: arrange six regiments of six officers each of six different ranks into a 6x6 square so that no regiment or rank is repeated in any row or column. Note that there are no diagonal restrictions.
It turns out that there are no GraecoLatin squares of order N=6 but this was not proven until 1901 by Gaston Tarry who exhausted all possible arrangements by hand. In 1959 Euler's conjecture was shown to be false for N > 6, by Parker, Bose, and Shrikhande. Rob Beezer shows a nice colorful order 10 square on his web page.
Since in such a superposition, the Latin Squares used cannot both be standard, a GrecoLatin Square in standard form is one where the first Latin Square is standard, and the second has only its first row in lexicographical order.
The maximum number of Latin Squares of order n which can be in a set of MOLS is n1, but some Latin Squares have no mutually orthogonal mates.
In GrecoLatin Square puzzles of order N=4, the pieces are an assortment composed of all the combinations of two features each having four possible values. They must be arranged in a 4x4 grid such that no two with the same feature appear in any row, column, or main diagonal. Sometimes it is prohibited to have a repeated symbol among the four corners of the square, or among the four central cells (see "1000 Play Thinks" #400). There is only one order 4 GraecoLatin Square in reduced form, but it does not meet these additional constraints. But by permuting rows, you can arrive at my solution for an order 4 GraecoLatin Square that meets all those conditions:
Aα  Bβ  Cγ  Dδ 
Cδ  Dγ  Aβ  Bα 
Dβ  Cα  Bδ  Aγ 
Bγ  Aδ  Dα  Cβ 
Bali Buttons Requires you to place the sixteen tokens  all combinations of four different shapes with four different colors  on the 4x4 board so that no row, column, or main diagonal contains more than one token with a given shape or color. This is a GraecoLatin Square puzzle. 
Four Square from the Embossing Company, Albany, NY Combines a GraecoLatin Square puzzle with two sliding piece challenges.
FIRST.
Place the blocks in the box so that no two of the same number nor of the same color
are in any of the 10 horizontal, vertical, or diagonal lines.
SECOND. Remove one of the 4's, then, by sliding them about, arrange them in horizontal rows, each of a different color, and in the order of 1,2,3,4. The fourth or bottom row should be 1,2,3. THIRD. After completing the second, slide them about again to arrange them as in second, but in a vertical position. 
Brain Strain An advertising puzzle consists of sixteen small playing cards  the Jack, Queen, King, and Ace in each suit. As with any GraecoLatin square puzzle, the objective is to arrange the pieces in a square grid so that neither of the two kinds of feature (in this case, face value and suit) appears more than once in each row, column, or main diagonal. This puzzle was first proposed by Jacques Ozanam. 

Quintessence Copyright 1970 by gametime, Inc. of NY, NY A 5x5 GraecoLatin Square  arrange the 25 pieces in a 5x5 grid such that no row, column, or diagonal contains more than one instance of a circle color or tile color.

There are 16 cards: four of each color  orange, purple, green, and yellow; four of each car model  roadster (92), touring (94), touring (96), and sedan (93); and each with a "license number" 1 through 16. The objective is to arrange them in a 4x4 grid such that rows, columns, and main diagonals contain cars of all different models and colors, and the sum of license numbers is 34 in all rows and columns and the four corners, the four centers, and each group of four in a corner!

Magic Squares exist for all orders except N=2. There is only one distinct Magic Square of order N=3. Supposedly the order 3 magic square was invented in China between 650 and 400B.C. and known as Lo Shu. There are 880 of order 4, and over 275 million of order 5.
In the order 3 normal square, all rows, columns, and the main diagonals total 15. The magic constant for a normal magic square of order n is given by the formula:
M_{n} = n(n^{2}+1)/2

Catch21 by Gabriel (U.S. Patent 3833222  Castanis 1974) and HiQ Enigma by Ideal are two puzzles where one must fit a group of pieces onto a surface bearing a pattern. Gridlock by Gabriel is a travel version of HiQ Enigma. The pieces match various portions of the pattern, and the proper "covering" must be found so that all the pieces will be accomodated and the surface completely covered. This will work with just patterns although both of these puzzles employ an embossed surface with corresponding holes in the pieces. Of the two, Catch21 is more logically straightforward. It includes a set of dominolike pieces.
Here is my solution "diary" for the 2nd side puzzle of Catch21. Please refer to the diagram at left. This shows the 6x7 board  the number inside each square indicates the pattern on the board. The numbers outside the board label the x (horizontal) and y (vertical) coordinate axes. I will refer to locations on the board via a pair of x and y coordinate pairs. The tiles consist of the 21 "dominoes" representing all ways of pairing the numbers 1 through 6.
Getting started here is not as easy as for the puzzle on the first side, since here there are multiple possible locations for every tile. Begin by considering where the 6/6 tile could be placed  there are only two possibilities: (0,2)/(0,3) or (0,1)/(0,2) shown in red. Choose to place it at the latter location. This forces 2/4 to go at (0,0)/(1,0).
Now review possible locations for the 4/6 tile  there were only two possibilities: (0,2)/(1,2) or (1,0)/(2,0) but the former has been eliminated by our choice of location for 6/6, and the latter has been eliminated by the forced placement of 2/4. Ergo we have made an error and must backtrack.
The only decision point is our choice of placement for 6/6, so we must undo everything back to that point and choose the only available alternative, placing 6/6 at (0,3)/(0,2). This still precludes one location for 4/6 and forces 4/6 to go at (1,0)/(2,0). The 2/6 tile must go at (0,0)/(0,1).
Now consider the 6 at location (5,0). It could be covered by either the 2/6 tile or the 3/6 tile, but 2/6 has been used so 3/6 must go at (5,1)/(5,0). Next consider the 3 at location (0,6). It could be covered by the 3/6 tile or the 3/4 tile, but 3/6 has been used so 3/4 must go at (0,6)/(0,5).
All squares in column 0 have been covered except for (0,4), which now must be covered using the 1/4 tile at (0,4)/(1,4). Now look at the 6 at location (1,6). It could be covered by the 2/6 tile or the 5/6 tile, but 2/6 has been used so the 5/6 tile must go at (1,6)/(2,6). This forces us to place the 2/4 tile at (1,5)/(2,5). Now consider the 6 at location (5,4). It could be covered by 1/6, 3/6, or 5/6, but we have used the latter two so it must be 1/6 at (4,4)/(5,4). Now consider the 4/4 tile. The only remaining possible location for it is at (2,4)/(3,4). Likewise consider the 1/1 tile. It can only go at (3,3)/(3,2).
Next consider the 5 at location (4,3). Either way it must be covered by the 5/5 tile. This implies that the 1/5 tile must be aligned next to it. There are two ways of placing them and either is OK.
Consider the 1 at location (4,1). Either way, it must be covered by the 1/2 tile. This implies that the 2/5 tile must be aligned next to it. There are two ways of placing them and either is OK.
Now look at the 2 at location (2,1). Since the 2/5 tile is used, we must use the 2/3 tile here. Next consider the 4 at (1,2). Either way it must be covered by the 4/5 tile and the 3/5 must be aligned next to it. There are two ways of placing them and either is OK.
There remains only 1 location for 2/2, at (3,6)/(3,5). Lastly, consider the 3 at (5,6). It must be covered by the 3/3 tile and the 1/3 must be aligned next to it. Again, two arrangements are possible and either is OK.

Instant Insanity was invented by Franz O. (Frank) Armbruster, a California computer programmer, and marketed by Parker Brothers during 196667. It sold about 12 million copies.
I have an original from Parker Brothers, and copies from Winning Moves (found in a shop in Mystic) and Kadon.
There are many puzzles in what I call the "Instant Insanity Family." Typically, the puzzle comprises four colored cubes. Four colors are used, and each of the cubes' faces are colored with one of the four colors. The objective is to find a linear arrangement of the cubes (a rectangular prism) such that all four long sides show each color only once. The faces on the ends and in between cubes don't matter. There are 41,472 distinct ways to line up the four cubes, so exploring them all by hand will take a while!
The number of ways to color a cube, allowing repeated colors, with at most k colors is given by
Polya's Enumeration Formula,
which follows from
Burnside's Lemma.
The formula for a cube is:
This gives the following values for k=2,3,4,... (Sloane's integer sequence A047780):
10, 57, 240, 800, 2226, 5390, 11712, 23355, 43450...
So for fourcolor type puzzles such as Instant Insanity, there are 240 possible cubes to choose from when creating the puzzle. The trick is to find a set that guarantees a solution, and preferably only one solution!
The cubes are typically diagrammed by "unfolding" them and representing them as a cross:
Note that when coloring a cube, once you've colored two pairs of opposing faces, then given colors for the last pair of opposing faces, you define a pair of mirror image cubes by assigning the colors to those two remaining faces in one way or the other. For purposes of this type of puzzle, mirror image cubes are identical and distinctions between them are immaterial to the solution.
Ivars Peterson's MathTrek article of August 9, 1999, "Averting Instant Insanity," is devoted to graphical solution techniques pertaining to this type of puzzle.
I learned from David Singmaster's notes that, according to Thomas O'Beirne, writing in the Mathematical Gazette, Vol. 41, No. 338, Dec. 1957, the graphical technique seems to have first been published in 1947 by Cedric A. B. Smith, writing as "F. de Carteblanche" in Eureka No. 9 (April 1947)  "The Coloured Cubes Problem" pp.911. O'Beirne discusses the puzzle in his 1965 book Puzzles & Paradoxes in chapter 7, though he doesn't reference Carteblanche there. O'Beirne's article on the "Great Tantalizer" from his Puzzles & Paradoxes column in the New Scientist of Aug. 10 1961 is online at Google books.
For the graphical solution technique, the set of cubes is represented as a single undirected pseudograph. The term "graph" usually formally excludes more than one edge connecting any two nodes, and self loops. The term "pseudograph" allows both, and we need both for this type of puzzle. Each of the four colors is a node. Each cube results in three labeled edges on the graph (for twelve edges altogether)  an edge connecting two nodes (or a node with itself) when those two colors appear on opposite faces of the cube, labeled with an identifier for that cube. Given this graph, the solution to the puzzle can be determined, and all puzzles of this type with isomorphic graphs are in essence identical. Note that the Graph Isomorphism Problem is a wellknown area of research.
On the right is the graph for Instant Insanity (I numbered the cubes arbitrarily).
Here is my copy of the solution letter sent out by Parker Brothers on request:
The Schossow / Katzenjammer Puzzle  
The first puzzle in this family was designed and patented in 1900 by Frederick A. Schossow of Detroit. It was marketed as the Katzenjammer Puzzle. An original cardboard container I have is marked "The Katzenjammer Puzzle  B. W. Gottechalk Patentee Chicago, Ill. U.S. Patent No. 646463  Price 10 Cts." The four blocks were marked with the four suits of a deck of playing cards  hearts, clubs, diamonds, and spades. The Katzenjammer puzzle is described on page 38 of Slocum and Botermans' 1986 book "Puzzles Old & New." According to Slocum, this puzzle appeared in the Johnson Smith Catalog of 1919. Slocum's book shows the layout of each of the four cubes, as does the patent, pictured here. In the physical puzzle, each block is a different color  orange, pink, green, and yellow. (I have a complete example and another example with one block missing. I am missing the fourth block from the top in the illustration in the book, which I believe is the yellow one.) "Directions  Mr. Katzenjammer brought this little box of blocks to his wife, and said to her: 'Katerina, you will notice that on the top row of these blocks there is a diamond, a heart, a spade, and a club. Now take the blocks out of the box and place them together so that all four sides will have one spot of each kind in a row. It comes easy, Katerina,' he said. 'If you look at the picture on the box, because that has one spot of each kind on two sides already yet.'" 

Here is a graph of the Katzenjammer puzzle, sidebyside with the graph for Instant Insanity:
It turns out that the Instant Insanity puzzle is isomorphic! I've colored the Schossow nodes to show the correspondence. I numbered the Schossow cubes according to their topdown order in the patent image. I numbered my Instant Insanity cubes arbitrarily  turns out II#1 maps to SK#3 and viceversa. II#2 = SK#2 and II#4 = SK#4. I've analyzed over 20 puzzles in this family, and most of them copy Schossow's design. O'Beirne had already remarked that many versions of this puzzle known to him were isomorphic  including the Katzenjammer, Great Tantalizer, and Symington's. The symbols might be replaced or remapped, but the essential pattern of the set of cubes is isomorphic. For example, see patent 02024541  Silkman 1935. Silkman's cubes are virtually identical  just the symbols have been remapped, and two cubes are mirror images of Schossow's, but this makes no difference to the solution.


So, how does one establish that two such puzzles are in fact isomorphic? Well, I read up on the Graph Isomorphism Problem mentioned previously, and found references to nauty by Brendan McKay, which is evidently the best publicly available software. However, it seems like overkill for my purposes. One also needs a way to represent graphs as data  there seem to be two good standards, DOT and GXL. I've chosen DOT since the graphviz package is handy. I categorize these puzzles by a numeric shorthand: the number of faces per element, the number of elements, and the number of colors/symbols in total. IItype (Instant Insanity  type) puzzles, with 6 faces per cubic element, four cubes, and four colors, are (6,4,4) in my scheme. (6,4,4) puzzles are represented by pseudographs having exactly four nodes and exactly twelve labeled, undirected edges. For now I'll omit puzzles with fewer or more cubes, noncubes, and fewer or more symbols/colors. Many approaches to graph isomorphism entail establishing some way to convert a graph to a canonical form, and showing that two graphs with the same canonical form are in fact isomorphic. Another useful concept is the invariant  some property of a graph, that all graphs isomorphic to it must share  e.g. the number of nodes. Obviously, two invariants that apply here are four nodes and twelve edges. One can also try to define a complete or sufficient invariant which completely decides isomorphism  the number of nodes and edges doesn't meet this need. Yet another useful concept is the signature or certificate of a graph  a way of assigning a coded ID to the graph as a whole, that plays the role of a sufficient invariant. I've come up with what I believe is a good way of assigning certificates to IItype puzzles. First, encode the nodes using four hex digits (0F) based on their connectedness: The rightmost or least significant place counts the number of selfloops on the node. The other three places give the counts of connections to the other three nodes in no particular order, but sorted in increasing value from left to right. For twelveedge graphs, we really only need up to digit 'C' and in practice most counts are only as high as 3. For the II/SK puzzle, the four node codes are: 0221 (the green or heart node), 0230 (the blue or diamond node), 1221 (the red or club node), and 1230 (the white or spade node). This is convenient since each node gets a unique code. Next, encode the cubes themselves, each as a series of six nodecodes derived previously  remember, an edge on the graph was defined by a pair of opposing faces on the cube. So an edge can be encoded with 8 digits by concatenating the codes for the two nodes it connects, sorted in lexicographic order (the edges are undirected, after all). And, a cube can be represented with 24 digits by concatenating the codes for the three edges it contributes to the graph, again sorted. These two sorting steps mean that we lose info to distinguish mirror image cubes, but as previously established, that doesn't matter to the solution! Finally, the whole puzzle's 96digit certificate is the four codes for the cubes, again sorted. And here again, the sorting doesn't matter, since the order of the cubes doesn't matter to the solution. For the both the Instant Insanity puzzle and the Schossow/Katzenjammer design, this certificate is (shown with some punctuation to aid understanding):
02210221023012210230123002211221
My claim is that any (6,4,4) puzzle with this certificate is isomorphic to the original Schossow design.

The pieces aren't always cubic... 

This is the Masudaya Hexagon Mind Exerciser. It has six hexagonal pieces. The objective is to line up the six hexagons so that each of the six rows of six faces shows all six colors. Unlike a set of cubes, where on each cube two faces are not used in a solution, here all six faces of every hexagon will be used. This means that there must be in total six faces of each of the six colors. In my copy of the puzzle, all six hexagons have distinct color arrangements  i.e. there are no duplicate pieces. I have found at least one solution  one can employ the graphical technique, but not in exactly the same way as for cubic puzzles  here, three mutually consistent subgraphs are needed, and they are not independent. 
A vintage Cylinder Ten by Masudaya. Ten rotating disks each with ten color segments. The English instructions say, "Arrange 10 different colors in a line to get all rows correct. The probability of getting the correct order is one in a billion. This puzzle will give the whole family hours of amusement. Note: it is packed in the factory with colors in the correct order (i.e. the solution)" There is no date I can find on any of the material. However, I translated "Cylinder 10" into Japanese and did a search on Google Japan just to see what would turn up, and I found a "FrogPort" blog article from April 2008 talking about the release of this puzzle and how it is in a series with Masudaya's other puzzles Face 4, Hexagon Mind Exerciser, and Circus 7. Here is a link to the blog via google translation to English. The instructions say "10 different colors in a line" but do NOT stipulate that the SAME ten colors must be in every line! This is unlike the traditional Instant Insanity type where one of each color must be present. This allows the rotating disks to have repeated or missing colors. A "line" is a row of stickers across all ten disks. There are ten disks each with ten positions/stickers, so they are accurate in saying one in a billion, since there are 10^9 possible settings (the setting of the first disk is immaterial).

I used the graphical technique to solve Nice Cubes:
Below is my solution to the Masudaya Cubes, using the graphical technique. The connectivity of this graph is similar to that of the Nice Cubes, though its edges seem differently labeled. Are the puzzles in fact isomorphic?
Recall that there are 240 ways to color a cube using 4 colors. Given a "stable" of 240 cubes from which to choose four, how many possible 4cube sets are there? To allow repeats but eliminate sets that are identical (since the ordering of the 4 cubes does not matter), we use the formula for a multicombination:
(n+k1)_C_k
In our case, n=240 and k=4, (240+41)_C_4 = 141,722,460. So, we've got over 140 million sets to explore! Also, for a set of 4 cubes, there are 41,472 possible ways to arrange them  that's going to be a lot of work.
But we can reduce this by eliminating from consideration all cubes that do not have at least one face of each color. It's a little arbitrary, and it means my conclusions are not universal over the entire universe of possible puzzles, but I think it's reasonable  most commercial puzzles comply. Of the 240 possible fourcolor cubes, there are 68 that use all four colors at least once each.
Each cube can be represented by a fournode, 3edge pseudograph, where the nodes are the four colors symbolized by the letters ABCD and each edge corresponds to a pair of opposing faces on the cube. The graphs are the same for mirrorimage cubes, since the edges are undirected. The 68 cubes give rise to only 52 unique graphs. Those 52 graphs can be grouped into 6 groups  each group is closed with respect to a permutation of the node/color assignments, of which there are 24 (4!).
Below is a chart I made identifying the 52 graphs/cubes by unique ID number (0051) and a small diagram showing the 3 edges. The colors identify the six groups. It should be easy to construct a cube given its little diagram and the key on the lower right. You just have to decide on your assignment of actual colors to ABCD, and then be sure to remain consistent.
Rick Eason worked on this problem, too, after we talked at NYPP2010.
Rick assigned numbers to these groups as follows, and noted that cubes in a group have the given number of possible effective orientations within a puzzle,
ranging from 10 to 24.
A higher number of possible orientations might contribute to a harder puzzle.


Here is a chart of number of solutions, number of sets that have the given number of solutions, and the first set found that has that number of solutions. I have omitted solution counts where no set had that number of solutions.
A set is represented by its "signature"  an eightdigit number (zeroes on the left, if dropped, should be inferred) that is simply the four cube IDs (0051) from the chart, concatenated, always from lowest numerical ID on the left to highest on the right.

I found 5160 sets that have a single solution. There were many sets  almost half  that had no solution at all. Some sets have more than one solution, and the maximum number of solutions any set can have seems to be 160. Most solvable sets have four solutions. There is only one set that has exactly 27 solutions, and 27 solutions is the only count where only one set has that count. Interestingly, the cubes used for this set are the four from the yellow group in the chart. It is not hard to solve this set by hand.
Based on a cursory check, it appears that none of the cubes in groups 5 (tan) or 6 (blue) are used at all in singlesolution sets!
Rick Eason says that by using Burnside's Lemma to eliminate color permutations, the 270,725 figure can be collapsed to 11,746 sets. If we further eliminate the 12 cubes not used in singlesolution sets (the tan and blue groups), we end up with only 3949 sets. I did not perform this collapsing for my runs, so my totals do not take into account color permutations.
In a brief 1977 paper entitled On "The Tantalizer" and "Instant Insanity" (PDF online here), Frank Harary (19212005), recognized as one of the fathers of modern graph theory, notes that "Using standard methods of graphical enumeration [Harary and Palmer 1973], it is not difficult to develop a formula for the number of different 'Tantalizer' games with four cubes. This can be done by associating a graph with each such game, and then counting graphs." When I first began to research this topic, I checked Harary's book out of the library, but I failed to find a handy formula for enumerating these graphs. If you know of one, please let me know!

The set identified by O'Beirne in his Great Tantalizer article in Figure 1 is the first listed, 01042040.
SK consists of 1 cube from group 2 (green), 1 cube from group 3 (teal), and 2 from group 4 (lavender). Rick suggests that the most difficult puzzles will consist of only cubes from groups 1 (yellow) and 4 (lavender), since those groups offer the most possible orientations (24 each). Rick found the following 13 singlesolution sets using only cubes from groups 1 and 4:
00 03 04 19 00 03 04 20 00 03 04 30 00 03 04 31 
00 03 04 39 00 03 14 19 00 03 14 20 00 03 14 22 00 03 14 37 
00 03 14 39 00 03 14 41 03 04 08 12 03 04 12 20 
Could these be the most difficult puzzles of the Schossow/Katzenjammer/Instant Insanity family?
The certificate with the smallest number of sets having that certificate is shared by only six sets:
02202240022022402240224002202240
02202240224022400220224002202240
22402240022022400220224022402240
is assigned to sets:
00030419, 00071231, 00081441, 19203031, 19223741, and 31333941.
In each set, a given pair of colors appears only once each on adjacent sides on all four cubes, with the other four sides of each cube having the other two colors. The graph of such a cube will have only one edge leading from each of the two colors, which will not share an edge. Four colors, taken two at a time, 4_C_2, gives the 6 possibilities. In signature order, they are: CD, BD, BC, AD, AC, and AB. These sets are easy to solve  identify the special colors. Orient all cubes so that the sides with the special colors are on top and front. Now it is a simple matter to turn three of them so that the solution is found.
At the other end of the scale, there is one certificate that encompasses 144 sets:
11201121112112211221122111201221
11211121122112211120122111211221
12211221112012211121122112211221
The first example having that certificate is 00162936.
According to my analysis, there should be 200 distinct singlesolution puzzles, where every cube uses all four colors, and each set uses four distinct cubes. You can download a text file "singlesolnsigsandcerts.txt" in which my program output cube set signatures and certificates for every singlesolution set. Those sets isomorphic to SK are noted. The tail of the file contains a summary of the 200 unique certificates and the count of sets having a given certificate.
The table below lists, in (mostly) alphabetical order (I tried to keep sequels together), those I know of and shows images where I either have a copy or have been able to find pictures. I don't have them all and I will note the ones I don't have. Those I have are highlighted like this. Those I do not have are highlighted like this.
I would like to acknowledge the following:
Bananas
Bananas 1982 Onsworld Ltd. "Arrange cubes to show four complete bananas each with a label." There are four cubes, and four types of side: a banana tip, stem, middle segment with no label, and middle segment with label. Unlike a standard IItype puzzle, the images have distinct orientations which must be respected to form the complete bananas. The tips, stems, and middle segments must all be aligned properly. A little analysis reveals that the usual fourinarow arrangement of the cubes cannot satisfy the goal  but then, the objective does not stipulate that arrangement, does it?

[22/54]
Various pamphlets or sheets accompanying the different puzzles mention other puzzles in the lineup. Several mention 5 puzzles but list 6; one describes Mindbenders as "a fiendish series of six diabolical puzzles" but then lists eight. I have found ten altogether.
The most frequently mentioned, most dating from 1969, are:

Less often mentioned, dating from 1970 and 1971, are:



The Perfect Square 1969 #505 Assemble a square using 12 pieces  like colors must not touch. 
The Tricky Triangle 1969 #505 Using 10 barbellshaped pieces composed of two linked circles each, and one single circle, build an edge6 equilateral triangle (of 21 circles) such that "no two circles of the same color are in the same line of the triangle." Each circle is 1 of 6 colors. The Tricky Triangle puzzle by Waddingtons is a 2dimensional analogue of Oops Again. 
The Perfect Circle 1969 #505 Assemble a circle from 16 pieces in 4 basic shapes and 3 different colors, such that likecolored pieces don't touch. 

The Wobbly Web Copyright 1969 No. 505 Create a rectangle from the 15 square tiles such that web strands join (edgematching). JH Vol.2 p210 
The Perplexing Pyramid 14 square tiles each of which has a colored circle in each corner. Create a "pyramid" of cards  a 3x3 base, then a 2x2 layer, then one card on top  layers must align over spots, and spot colors must match vertically. 
The Reluctant Rectangle 1970 #345 Form a rectangle from the 12 3x2 Lshaped pieces such that no two pieces of the same color touch in any way. There are 3 pieces each of four colors. All the pieces are "normallyhanded" L's except for two of one color are reversed. 

Little Circles 1970 #346 Pack 18 pieces formed from circles into the box. (The instructions are printed on the box, and there is no mention of a colordismatching constraint.) No Pamphlet. 
Coloured Square 1971 #340E Form a square from 12 Lshaped colored tiles such that like colors don't touch. 
Rectangle Tangle 1971 #340F Form a rectangle with a bicolor perimeter from the 10 tricolor and 2 bicolor LTrominoes. 

Beat the Elf  by House of Games Corp. Ltd. Don Mills, Ontario 1970 Build a 3x3x3 cube with the 13 blocks so that no face shows three squares in a row of either color, horizontally, vertically, or diagonally. There are 11 1x1x2 blocks of 1 light and 1 dark. There is one 1x1x2 block of two darks. There is one 1x1x3 block of two lights (adjacent) and 1 dark. 
Kolor Kraze  by House of Games Corp. Ltd. Don Mills, Ontario 1970 Discussed in Slocum and Botermans' Puzzles Old and New on page 43. The Kolor Kraze puzzle consists of 12 dicubes and a tricube, each made of differently colored cubes. There are 3 each of 9 different colors. As in the Gram's Cube, the goal is to create a 3x3x3 cube from the pieces, such that each of the 9 colors appears only once in each of the six faces of the cube. Sivy Fahri wrote an article about the Kolor Kraze and the Nine Color Puzzle called "Nonahuebes" he developed based on it. A PDF of Fahri's article is available at the Gathering 4 Gardner Wiki. 
Cube Fusion Alright, it's a game not a puzzle, but I remembered these pieces from my childhood and now I know what they belonged to! 
Gram's Cube was made by Gram Toys of Birkerod, Denmark. The puzzle consists of 27 Legolike cubies that mate sidetoside as well as upanddown. There are 3 cubies each of nine different colors. The objective is to construct a 3x3x3 cube such that each side shows all 9 colors. At first I thought a trick was necessary, but I found a solution using all 27 cubies. I picked this up in a trade with Norman Sandfield, at the January 2005 New York Puzzle Party. 
Level Q, by Eng's IQ Co. Ltd. 1987 Hong Kong. I purchased this quite some time ago. Level Q consists of a hexagonal board and twelve barbell shaped pieces. There are three challenges  first, build seven stacks of six disks each. Next, again build seven stacks of equal height, but such that one bar lies on each side of the hexagon and on each of the six spokes. Finally, satisfy the constraints already mentioned, and also ensure that each stack contains only one of each color disk. 

The Trapagon and Magzphere Six pieces interlock  arrange them so that there are five different colors on each "face." 
The object of Oops Again is to build a pyramid with the 2sphere pieces so that no two spheres of the same color touch at all. The Golf Smarts Pyramid (a gift from Brett) is similar. 

Tetraball  designed by John Conway and Richard Esterle You can read about this puzzle at ludusopuscula.org. You may notice the label on mine is mirrorwritten. That's intentional  I bought a rarer version. Purchased at NYPP 2016. Make a set of small 4ball tetrahedrons, then assemble them into a large tetrahedron such that like colored balls do not touch. 

Spot Cube  Hikimi Designed by Ichiro Sengoku, this puzzle was entered in the 2004 IPP Design Competition. I bought it at Torito.

Vier Farben Block  Logika Build a cube with the 12 ushaped pieces such that like colored pieces do not touch. Each piece is one of four colors. 

Instant Indecision marked "Patent Pending"  the Green Gate Co. Sherman Oaks CA, 1972 Four cubic frames and a stepped pedestal. Each cubic frame contains twelve bars, 3 each of four overall different colors, arranged in various patterns. The four cubes are of graduated sizes and nest on the pedestal. The objective is to arrange the cubes in nested form on the pedestal so that each of the twelve sets of four aligned bars, one from each cube, contains one of each of the four colors. My version has a nice keylike tab that locks into the pedestal and holds the cubes in place for storage/transport. 
Cube Edu  eLogIQ Build a 2x2x2 cube and match colors on all faces. 

Octamania Arrange the 8 cubes into a 2x2x2 cube such that each face shows four copies of a digit. 
The vintage 8 Blocks to Madness puzzle  invented by Eric Cross of Ireland, and issued by Austin Enterprises of Ohio. Create a 2x2x2 cube having a single color on each side. Then create a 2x2x2 with each of four colors on every side. 

The Maze Cube  stack the four bricks together to make a 2x2x2 having four colors on each face. 
Poker Cubes I don't have any documentation with this puzzle, so I don't know the provenance or goal. However, I suspect the goal is to create a 2x2x2 having one of each of the four suit symbols on every side, while also ensuring each 2x2 face is a single color with each face a different color. 

The Ten Spot Domino Puzzle Issued by Valentine & Sons, Ltd. Westfield Works Dundee The instructions inside the box top read, "Valentine's Series of Popular Puzzles The New 10 Spot Domino Puzzle Instructions  Arrange the four pieces so that they form a solid square block, every side of which shows 10 spots. Solution sent on receipt of 1d. stamp."
Discussed by Slocum & Botermans in their 1994 book The Book of Ingenious & Diabolical Puzzles,
on page 34. The layout of the pieces and one solution are provided on page 143.

I finally found a Cover Up  issued by Ideal in 1982, it originally appeared as
Hepta in 1974 and was designed by the famous Alex Randolph.
See the
entry for Hepta at Boardgamegeek.
I had wanted to try this puzzle since reading about it at
Celia Seide's website.
Celia also pointed out
Spielarchiv.de which has a reference to a version called Magic 7 under Spiele>nach Autoren>R>Randolph,Alex > Magic 7.
There are seven plastic 1x3 straight pieces and seven angle pieces. The plastic 7x7 board is colored using 7 colors each of which appears 7 times. For each of the 7 colors, use all the pieces to cover all the spots not of the target color. It's pretty large  I put a quarter coin on the cover.


Cubic Mania Puzzle Blocks was issued by Dale Seymour Publications. It comprises eight cubes, each colored with four colors. Each cube uses each color at least once. Using the chart of cube graphs I developed, the included cubes can be mapped to the tan set { 24 x 3, 27, 34, 42, 43 x 2 }. There are several challenges, including building a 2x2x2 where every side shows all four colors, and another where every side is a solid color. 
Brain Wave Arrange the bicolored pieces in the slots so that no color is repeated along any line of the triangle on both sides of the head. 

Lucky 13, Edition No. 7, by Fireside Games Inc. of Northbrook Illinois, 1973.
24 different puzzles  in each, arrange 13 pieces to
form a 7x7 square such that like colored pieces do not touch, even at the corners.
Any piece may be flipped.

If each of the n faces of a regular solid is colored with one of n colors, the number of different ways the solid can be colored with all n colors excluding rotations but including reflections is given by n!/(2*E) where E is the number of edges of the solid. For cubes with 6 faces and 12 edges, the number of possible colorings is 6!/(2*12) = 720/24 = 30. These 30 cubes form the set of MacMahon Colored Cubes.
You can choose any of the 30 cubes to use as a "prototype" and it will be possible to find eight other cubes in the set which can be used to build a 2x2x2 model of the prototype having the same arrangement of solid colors on the six external 2x2 faces as on the prototype's six faces, and also satisfying the additional constraint that internal touching faces are colored alike. MacMahon credited his friend Colonel Julian R. Jocelyn with the discovery that this can always be done regardless of which of the 30 cubes is chosen as the prototype.
For each prototype, there is only one set of eight cubes which will work, and there will always be two ways to build the prototype with these eight cubes. A procedure to transform one solution into the other was devised by L. Vosburgh Lyons and is shown in [2] on page 190. The eight cubes to be selected will not possess any of the same pairs of opposing face colors as the prototype. This means that 13 of the 29 cubes can be eliminated as candidates, leaving 16 from which to choose.
Lyons also discovered that after a 1st prototype is selected along with the eight cubes to model it, it is always possible to select another prototype from the remaining 21 cubes, and find another 8 cubes from the remaining 20 to model this 2nd prototype. The 2nd prototype must be a mirror image of the 1st, and the eight cubes to model it are the eight not chosen from the 16 eligible for the modeling of the 1st prototype [2].
MacMahon sold an eightcube puzzle patented in 1892 (UK 8275?) to the London company R. Journet, which marketed it as the Mayblox puzzle [4]. Its eight cubes are one of the sets which can model a prototype and meet the internal colormatching constraint. However, the Mayblox puzzle does not specify the configuration of the prototype  so it must be deduced, which makes the puzzle more difficult.
I made my own version of a Mayblox puzzle using LiveCube. I chose a prototype arrangement of six colors at random, then colored the 8 subcubes as required based on the solution instructions in [1]. I finally found a good use for the LiveCube face plates! Fortunately, they provide enough different colors with the addition of cyan and pink to their previously available black, red, yellow, green, and blue.
You are to build a 2x2x2 cube using 8 of the 9 included numbered dice, so that every face displays a unique number.
There have been several issues of sets of "pattern blocks" under various names.
Pattern Pending designed by Fred Horowitz and issued by Parker Brothers (General Mills) in 1971. A set of 12 black and white cubes. Fred had the basic idea for these in the 50's, and intended these to be more of an openended creative playset than a puzzle.

Sudoku 3D Ball  22 Advance www.3djp.com There are 5 circular indents on each pentagonal face of the spherical dodecahedron, and 10 indents in a "ring" bordering each face. Each indent is a member of 2 "rings"  those around the two faces adjacent to the vertex where the indent is located. Some indents already contain a digit from 0 through 9. Fill in empty indents with digits from 0 through 9 such that every ring contains all 10 digits. (The sphere is not meant to be disassembled.)
