This is the touchscreen version of the Rubik's cube that first challenged puzzle-solvers nearly 30 years ago. Instead of turning each face of the cube to line up colors, modern-day players need only lightly swipe a section of lights with a finger in the same manner as the original. Touch sensors on all sides detect your finger and a motion detecting accelerometer determines which face is active; the colors change according to the direction of your finger's swipe. Its built-in memory saves your puzzle so you can pick up where you left off. It can offer hints, or if you are truly exasperated, it can solve itself. The cube recharges in eight hours using its display stand, allowing one hour of play. Ages 8 and up. 3" cube. (8 oz.)
