Vee-21TM
This sweet and innocent-looking set of 21 V-shaped trominoes (3 squares each) can entertain a four-year-old with simple patterns, yet infuriate a grown-up expert with tough challenges. Math professor Norton Starr originally commissioned this set to demonstrate proof of a theoremthat an 8x8 grid can be filled with V-trominoes no matter where you leave the empty space. We coupled this puzzle with a color-separation feature, then added an original concept by Oriel Maximé, of filling the Vs on grids around strategically placed barricades. The 28 "Bends" layouts cover four levels, from Easy to Expert. Other challenges and game rules are included. A feature not shown in the booklet is a pretty alphabet, discovered later. All acrylic, 7 tiles each of 3 luminous transparent colors in 7" tray with engraved grid lines. You can choose from three color combinations. Ages 4 to adult, 1 or 2 players. |

SNOWFLAKE SQUARETM
This one was an instant hit with audiences of all ages. 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 our grown-up version, Snowflake Super Square. Snowflake is available in several color choices. The three-color mix in 5.75" tray offers diverse challenges, well suited for ages 7 to adult. |

Mini-IAMOND RINGTM
Nine easy pieces fill the encircled
pattern in thousands of ways. You can have the "diamond" piece in any of 37 different positions, and form a large variety of shapes outside the ring, too. All acrylic, five-color mix in a 5˝" tray. For 1 or 2 players, ages 6 to adult. |
