Stay in the game and get to the serving square #1.
A player standing with one foot in the serving corner of the square #1 serves the ball by hitting it from underneath with both hands, so that it bounces into any one of the other squares. The player in the receiving square keeps the ball in play by hitting it from underneath off the first bounce only and into another square. Play continues until a player fouls by failing to return it properly. This player leaves the game and goes to the end of the waiting line. The remaining players advance one square toward square #1, if there is a open square because of a player who made a foul. The next person in line will enter the game into square #4. Play is always started by a serve from square #1. A player is not confined to their square, and may go anywhere to best hit a ball that has bounced in their square. They may do this as long as they do not interfere with a person in another square.
