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). Its name is derived from the Portuguese futebol de Salão and the Spanish fútbol sala, both of which mean hall football. However, the game should not be confused with futebol de Salão itself.
Futsal is played between two teams of five 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. The ball used tends to be slightly heavier and smaller (size 3+) than football, and thus promotes better ball control skills as well as passes on the ground. Furthermore, the smaller play area forces players to improve their skills and decision making.
Other forms of indoor football games, which are played by somewhat different rules, exist 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.
A governing body was created in 1971 to administer the game and its championships; this was the International Indoor Football Federation (FIFUSA, from the initials in both Portuguese and Spanish), which later became the Worldwide Futsal Association (AMF). FIFA took over control of the game in 1989 and continued the tournament in its name. New rules and amendments to previous rules were created by FIFA at this point. One of the most remarkable changes was the reduction of the ball weight and increase in ball size (from a size 2 to 4), which made possible faster play and, for the first time, scoring goals with the head (though this is still difficult and uncommon).
FIFA's regulating of the game has led to increasing interest, and increased participation, in futsal. Many countries are attempting to promote futsal over the informal (and 'unofficial') form of five-a-side football.
