The game of jacks has been a playground game for many generations. Players learn socialization skills, hand-eye coordination and fine-motor skills when simultaneously bouncing a ball and scooping up a specific number of jacks. Can be played alone or with friends. The better you get, the more you want to play! Our nostalgic version comes with five silver jacks, five gold jacks, and two bright red bouncy balls. The jacks measure 1 inch end to end. A nostalgic game of skill and infinite fun. Perfect for travel!
