Squash is a fast-moving racket game which demands a high level of physical fitness and metal agility. It is played in special enclosed courts and the ball is only allowed to hit the ground once during play. To win a point, you have to force your opponent to commit an error, such as letting the ball bounce twice. You also score a point if your opponent hits the ball out of the court boundaries or is hit by the ball.
