Racquetball

Racquetball is a racquet sport and a team sport played with a hollow rubber ball on an indoor or outdoor court. Joseph Sobek invented the modern sport of racquetball in 1950, adding a stringed racquet to paddleball in order to increase velocity and control. Unlike most racquet sports, such as tennis and badminton, there is no net to hit the ball over, and, unlike squash, no tin (out of bounds area at the bottom of front wall) to hit the ball above. Also, the court's walls, floor, and ceiling are legal playing surfaces, with the exception of court-specific designated hinders being out-of-bounds. Racquetball is played between two players (in singles) or four players, two to a team (in doubles) who try to hit the ball with the racquet so that it hits the front wall before hitting the ground, such that an opposing team's player cannot bounce it back to the front wall. The sport is similar to 40×20 American handball, which is played in many countries. It is also similar to the British sport Squash 57, which was called racketball before 2016.
