Designed to develop colour matching and finger dexterity. Two players race to match the patterns provided on each of the 14 playing cards by moving the non-removable, coloured marbles with your fingers through the holes in the bottom of the puzzle boxes. Each pattern card is double sided and features blank outlines so you can design and colour-in your own patterns! Includes two sealed ball holders. The balls cannot be lost! Play competitively or solo. For ages 3 years to adult.
