The rules: There are many different versions of this game. The basis of each is to throw the ball into the air and catch it again after agreed moves have been made with the jacks. Put all the jacks on the ground. Throw the ball into the air, pick up two jacks, then three, then four and so on. A player’s turn ends if he or she drops the ball, or (if you are playing an easier version of the game) allows it to bounce more than once.
Warning: Not suitable for children under 3 years of age as small parts may present a choking hazard.
