A beautifully crafted game of visual dexterity. Players puzzle over how to recreate the patterns on the game cards using their set of 16, two color, half inch cubes. Comes with 120 pattern cards and enough pieces for 4 players. Or save some money and split materials so each teacher/therapist has 2 sets of cubes and 60 cards. Play "head to head", individually or as fast-paced 3 round competition. A great visual perceptual tool you will reach for again and again!
