Futsal

Futsal is the indoor version of association football (soccer) that is officially sanctioned by football's international governing body, the Fédération Internationale de Football Association (FIFA), as well as the Asociacion Mundial de Futsal (AMF). Its name is derived from the Portuguese futebol de salão, which means roughly room soccer (salão means "large room").

Futsal is played between two teams of 5 players, one of which is the goalkeeper; in addition each team may have a number of substitutes. Unlike some other forms of indoor football, the field is delimited by lines, and not nets or boards which the ball may be played off.

Other forms of indoor football games exist ,which are played by somewhat different rules, and may be referred to as indoor football, five-a-side football or indoor soccer. Those games predate the formulation of official rules of futsal.
