- To start the match, the right to serve is decided by the spin of the racket.
- The server can choose the service box in either side of the court.
- The server must stand with one foot in the service box.
- He/She drops the ball or throws it in the air and hits it before it touches the floor/walls directly to the front wall between the service line and the out-of-court line, so that it lands in the back half of the opposite court on its return from the front wall.
- Only one serve is allowed
- The server must alternate the serve from each side of the court if he/she continues to score a point. He/She continues to serve until he/she loses the rally. Then the opponent becomes the server and he/she has the right to serve from either side of the court.
After a correct serve, players alternate hitting the ball until the rally ends. That is when one of the player :
- fails to play the ball before it bounces more than once on the floor
- hits the ball into the tin
- hits the ball into the floor before it reaches the front wall
- hits the ball twice in succession
# The ball can strike the back or side walls in any combination in its flight towards or away from the front wall.
Principal Scoring : Point-a-Rally (PAR) to 11
Either player may score points. Each game is played to 11 points. The player who scores 11 points first wins the game except that if the score reaches 10-all, the game continues until one player leads by two points.
Alternative Scoring :
- PAR 15
- Server Only Scores (the previous standard scoring system)
- Boast: A shot played so that the ball hits the side wall before hitting the front wall.
- Lob: A shot played so that the ball hangs high in the air and falls almost vertically to die in the back corners.

- Volley: A ball hit before it bounces, either on the forehand or backhand side.
- Length & width: In squash, the players will try to hit the ball close to either walls (width) and to the back of the court (length).
- Nick: It is the junction between two walls or between the wall and the floor where the ball dies immediately.
- T-position: It is the area at the junction of the short line and the half-court line.
- Let: When one player interferes with the other's choice of movement to the ball or with the other's clear path for movement, he/she can call out loud 'let'. When a let is called and given, the rally does not count and is replayed. Stroke to (Name of the player): A call made by the Referee when one player interferes with the other's choice of movement to the ball or with the other's clear path for movement. The player named is to be awarded a stroke and wins that rally.
