Imagine yourself in the wild west, where the best shooter wins the duel...
Fold this piece of paper in half to start the game.
Fold the corner and fold the paper in half. crumple the end so that the paper resembles a drop - this is your bullet.
Take your ball by the sharp end between your index and middle fingers so that your hand imitates a revolver.
Stand back to back with your opponent and take 3 steps forward.
Turn to each other, keeping the hand with the bullet near your pocket.
On the count of 3, both players throw the bullets at each other.
If the bullet hits the leg or hand, for the next round the player must bend the limb and not use it. If you have to bend both legs, you sit during the next round. If you lost both hands, you throw the bullet with your mouth. The one who shoots all the limbs off first wins. If the player gets hit in the head or chest, it's an instant defeat.
