Simon is back again in a miniature 4-inch form--small enough to fit in a pocket but still featuring buttons large enough to play with friends. Press the circle in the middle and try this classic memory test as it adds one by one to a series of tones and colors. The more notes are added to the game, the faster it gets, so even memory pros may have a hard time following this computerized marvel all the way through a sequence. --John Longenbaugh
