Futsal? What does it mean? Football?

Futsal is an indoor version of football (soccer). Its name is derived from the Portuguese futebol de salão and the Spanish fútbol sala/de salón, which can be translated as 'indoor football'.

Futsal is played between two teams of five players, one of whom 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 that players can use to redirect the ball. Futsal is played with a #3 or #4 ball, which is slightly heavier and smaller than the #5 ball used in football.
