Raquetball is an indoor sport played with a racket and ball. The easiest way to imagine it is half-court tennis. The scoring system is similar to tennis or volleyball. It is characterized by a fast pace and high chance of injury by crashing into concrete walls, floors, or other players. You also have to get used to the strange echoing "Wabonnnnnng" sound and the squeaking of athletic shoes on waxed floors.
