The classic puzzle with a tactile twist! This blind-accessible version of the best-selling ultimate brain teasing puzzle has been enhanced with tactile markings. In traditional play, the puzzle is scrambled, and then solved by twisting and turning it to realign the six matching colors. In this version, in addition to colors each of the sides has unique tactile markings (circles, triangles, dots, etc.) so it can also be enjoyed and solved by touch only.
