Squash is a racket and ball sport played by two (singles) or four players (doubles) in a four-walled court with a small, hollow rubber ball. The players alternate in striking the ball with their rackets onto the playable surfaces of the four walls of the court. The objective of the game is to hit the ball in such a way that the opponent is not able to play a valid return

1
Two players, each with a racquet, take turns to hit the ball onto the front wall within the large area defined by the red line at the top of the court (‘out of court line’) and the red line marking the top of the tin at the bottom of the front wall.
2
A rally begins when the server, electing to serve from either the left or right service box, strikes the ball so that it makes contact with the front wall above the service line and below the out line and lands in the opposite back quarter of the court.
3
The receiver stands in the opposite back quarter of the court. If the serve is good, the receiver strikes the ball towards the front wall. On its way to the front wall, the ball may hit the back or side walls first, but must not go ‘out of court’, hit an opponent, hit the tin or touch the floor before reaching the front wall. The receiver may chose to strike the service ball ‘on the full’. If the server wins the point, the two players switch sides for the following point. If the server loses the point, the opponent then serves, and can serve from either box.

Games are played according to point-a-rally scoring (PARS) to 11 points. PARS is almost universally preferred by the game's top professionals, and is the current official scoring system for all levels of professional squash tournaments. In PARS, the winner of a rally receives a point, regardless of whether they were the server or returner. Games are played to 11 and must be won by two points. That is, if the score reaches 10–10, play continues until one player wins by two points. Competition matches are usually played to "best-of-five" games (i.e. the first player to win three games).
Squash can also be played with different scoring systems such as PARS to 15, traditional English or Hand-In-Hand-Out (HiHo) scoring to 9
