This is the electronic handheld version of SET, the matching game featured daily in the New York Times. Based upon the 1974 card game that won a Mensa Select award, the game challenges a single player's spatial and analytic skills as they attempt to find unique "sets" from a matrix of nine objects--diamonds, squiggles, or ovals colored either red, purple, or green. The game provides four versions of the game (classic, timed, puzzle, and arcade). Can be played singly or against the computer. Requires three AAA batteries. 1" H x 2 1/2" W x 5" L. (6 oz.)
