1 SET - HANG TAG - The fun classic game of jacks. Includes 10 metal jacks and a 1" bouncy ball. The game of jacks is a good tool for building hand-eye coordination and motor skills! How to Play Jacks Drop all the jacks onto the table. The object of the game is to bounce the ball, pick up a jax, then catch the ball in the same hand after letting the ball bounce one time. Begin by picking up one jack, then two jacks, then as many as you can until you can get all 10! It starts with one jack at a time (onesies), then two jacks (twosies), right on up till the player misses. She continues at that number on her next turn. Then the next player goes. The game continues until someone succeeds at picking up the ball and all of the jacks at once on a single bounce.
