Draw a court on the ground with playground chalk—it’s just four equal-size quadrants, each at least 4 feet by 4 feet—and label them 1, 2, 3, and 4. The player in square 1 "serves" by hitting a rubber playground ball with his or her hands into one of the other squares. After one bounce, the player in that square must hit the ball into someone else's square, or that player is out. Players may never carry, catch, or hold the ball. Rotate spots based on game play — if the player in square 2 is called out, that player moves to square 4 (or to the sidelines if more than four players are involved) and the other players move up. The player in square 1 always starts the round and is often called the king; in some versions of the game, the king can make special rules that all the other players must follow.
