Squash is a racquet sport played by two or four players in a four-walled court with a small, hollow rubber ball. The players must alternate in striking the ball with their racquet and hit the ball onto the playable surfaces of the four walls of the court. The ball equipment for squash has two types of balls, one for competition and one for club games. The balls are fairly similar with only minor details in differences.
