SNOWFLAKE SUPER SQUARETM
...a dance of hearts and spaces

Many people, when they first see this puzzle, are reminded of M.C. Escher's work. It's easy to see why. The tiles are all the combinations of straight, convex and concave edges, transformed step by step from a regular square. The 36 tiles comprise the 24 permutations of hearts and spaces, plus 12 duplicates, divided into three colors. We use see-through colors mingled with black to give the all-acrylic set a stained-glass look. It looks really nice displayed on an easel. The tray is 8". Hundreds of symmetrical figures can be solved, and rules for 7 competitive games are also included, for 2 to 6 players, ages 12 to adult. $59

SNOWFLAKE SQUARETM

This one was an instant hit with audiences of all ages, from the first moment that we showed it (Oct. 1997). Strange how solvers keep misplacing the corner pieces. The free-form patterns, worked outside the tray, can be even more confounding. Rules for a simple game for two players are also included. The 16 acrylic tiles are a special subset of the larger square, above, in their own 5.75" tray. Snowflake is available in four color choices. The three-color mix offers assorted challenges, well suited for ages 6 to adult. $29

    The 24 wavy tiles are a complete set of all the combinations of four types of edge: straight, hills, valleys, waves. We intended it as a gentle tribute to M.C. Escher's genius in geometric transformations. Then we found that, mathematically, they are also cousins of Multimatch III triangles. The checkerboarding of solutions isn't required, but it's nice to know that most of the figures in the book can be solved that way. (Thank you, Anneke Treep, for working those out on our office rug.) And thanks to Toby Gottfried for proving by computer that this puzzle has 2.3 million solutions! Jacques Haubrich found that only 297 of those are checkerboarded. Toby then found that only 7 of those have the three same-sided tiles at the corners of the large interior triangle (see solution at left). He also found that there are 173 solutions with both colors grouped. All-acrylic, in bold and mellow colors, with 8" tray. Recommended for ages 12 to adult. $59

    An offshoot of MacMahon's squares, the 64 different 2" tiles of IZZI are almost a complete set of all the combinations of a square cut into 8 black and white triangles. The full set would be 70 tiles, so the 6 most regular tiles are omitted to get down to 64. Just match them exactly, black to black and white to white, on the sturdy die-cut cardboard squares. There are zillions of solutions, and you can see some gorgeous ones on Jaap's Puzzle Page. It's fun and a never-ending challenge for ages 8 to adult. $12

    The 12 large, all-different four-color diamonds form dozens of shapes. Just match them by color. Well-made die-cut cardboard pieces are pleasant to handle. This set is related to MacMahon squares (Multimatch I), in that each edge has its own color. But the squares have been stretched into diamonds (rhombs), and each tile has all four colors. We like the fact that this set is made up of all of its possible combinations. It's fun and a challenge for ages 8 to adult. $25

Each cube face has a different arrangement of its three colors, as two squares and a rectangle. So there are 120 all-different faces. You get a wealth of figures to solve by matching the cube edges. Games for beginners and experts are included. We have the beautiful first edition, handcrafted in Yugoslavia and numbered and signed by the inventor, in an elegant wood case with handfinishing by Kadon. About 1" cubes.
