The sport is open to both men an women, and is one of the only games which allows them to compete on the same team.
The game is played on a basketball court, with boundary lines, a centre line, centre circle and two key areas. Two cones at each end of the court mark out a goal area, and a goal is scored when a player carries a ball across the line.
Games are played in four eight-minute quarters and each team has 40 seconds to score a goal before the ball gets turned over. Chair-to-chair contact is allowed, but person-to-chair and person-to-person contact is not.
Teams are made up of up to 12 players, with four on court at any one time. Each person has a vital role to play, which is ensured by using a classification system based on muscle function and strength. Classes range from 0.5 to 3.5, and the team of four players must total eight points or less during play.
