Jacks are a classic children's toy consisting of a set of small, star-shaped pieces and a ball. Typically made of metal or plastic, the jacks are designed to be tossed and caught in a game that requires both skill and coordination. Players bounce the ball and attempt to pick up a specific number of jacks before catching the ball again. The game of jacks has been played for centuries and is often enjoyed by children in groups. It helps develop hand-eye coordination and fine motor skills. Jacks can be played on various surfaces, making them a versatile and portable toy for fun and entertainment.
