here is how you play:
This game is for 2 players or more. To begin, each player choose a jack color, and spins it, like a spinning top. The player who's jack spins the last starts the game
To play, start by throwing all jacks on the ground/pavement. Then, each player at his turn throws the ball high in the air. While the ball is in the air, he needs to collect as many jacks of his color, without letting the ball fall to the ground.
A player that loses his ball (falls to the ground) loses. A player who collected all his jacks before others - wins.
Can you imagine the fun...
