The player who wins the preceding game serves first in the next game.

4.3.To serve, a player shall release the ball from either a hand or the racket and then strike it. Should the player make no attempt to strike it after that release, the player shall release the ball again for that service.
4.4. A service is good if all the conditions in Rules 4.4.1 - 4.4.5 are met:
4.4.1 the server has part of one foot in contact with the floor within the service box without any part of that foot touching the service box line (part of that foot may project over this line if it does not touch the line) at the time of striking the ball;
4.4.2 the server, after releasing the ball for service, strikes it correctly on the first or further attempt before the ball falls to the floor, touches a wall, or touches anything the server wears;
4.4.3 the server strikes the ball directly onto the front wall between the service and out lines;

5. Rallies
After a good service has been delivered the players hit the ball in turn until one fails to make a good return. A rally consists of a service and a number of good returns. A player wins a rally if the opponent fails to make a good service or return of the ball or if, before the player has attempted to hit the ball, it touches the opponent (including racket or clothing) when the opponent is the non-striker.
6. Good return
6.1. After the server delivers a good service, the players return the ball alternately until one fails to make a good return.
6.2. If the return would have been good and the ball would have struck the front wall without first touching any other wall, the striker wins the rally, provided the striker did not “turn”. If the ball either had struck, or would have struck, any other wall and the return would have been good, a let is played. If the return would not have been good, the striker loses the rally.
