Tennis is a racket sport that is played either individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will.
Wheelchair tennis is one of the forms of tennis adapted for wheelchair users. The size of the court, net height and rackets are the same, but there are two major differences from pedestrian tennis: athletes use specially designed wheelchairs, and the ball may bounce up to two times, where the second bounce may also occur outside the court.
