The uniquely checkerboarded, reversible pieces are the 12 pentominoes plus a 2x2 square. They fill the 8½" tray as an 8x8 checkerboard in 1294 ways and serve for dozens of other puzzles plus three games. Two of the more stubborn puzzles are "the longest river"forming a single band of one colorand the "uncheckerboard", where you try to have no single squares of a color.
