1. Each player must stand behind a sidewalk square.

2. The Ace Square player serves by slapping the ball with the palm of his hand so it bounces in the Ace Square first, then ricochets and hits the wall, then bounces into another player’s square.

3. The player behind the square where the ball lands must hit the ball the same way, bouncing it first back into their own square, then against the wall, and into another square.

4. The game continues until a player:
> Fails to hit the ball after it bounces once in their square
> Fails to bounce the ball in their own square on the return
> Fails to bounce the ball against the wall so that it lands in another player’s square

5. Like in handball, players can step into their own square or "rush the wall" to get a ball on the first bounce.

6. When a player misses, he gets a letter "K" and must move to the end of the line (far right). All other players move up a square. For each additional miss, players receive another letter: "I, N, G, S." When "KINGS" is spelled, the player is out. The last player remaining wins the game.

Note: The player in the Ace Square always serves no matter who causes an out. If the player in the Ace Square misses, he goes to the end of the line but does not get a letter; he only loses the serve.
