To start the game, the player in square four serves the ball by bouncing it in their square once and then hitting it towards one of the other squares. The receiving player then hits the ball to any other player in one of the other squares.
The ball must bounce in another player’s square, and they must hit it to another player before it bounces a second time.
A player may hit the ball before it bounces, if they choose to do so.
If a player hits the ball so that it misses another player’s square, or fails to hit the ball before the second bounce after it has landed in their square, they are “out”.
When a player is out, the other players move up to take their place, and that player moves to the last square, or to the end of the line, if there are more than four players.
The object of the game is to move up to and hold the server’s position.
