Wheelchair handball four-a-side is practised by two teams of four players. Any player on the court may act as goalkeeper at any time. Therefore, the goalkeeper does not wear a special goalkeeper shirt but the same shirt as the rest of the team. For competitions with mixed teams, each team must have at least two female players in the match squad and one female player on the court at any time. 
Matches consist of two sets of ten minutes, which are scored separately. Between the two sets, there is a half-time break of five minutes. Each set requires a winner. If the score is tied at the end of a set, the winner shall be decided by golden goal. In the event of a set tie (after two sets), the teams will play a third set (tiebreaker) of five minutes. 

The size of the court is the same as for indoor handball, but the height of the goals is reduced to 1.7 m. The Rules of the Game for wheelchair handball four-a-side can be found here
