Law 11 states, "There is no offside in futsal". The Futsal Laws of the Game were designed to run parallel with the Association Football (soccer) Laws of the Game, in which Law 11 deals with Offside. As a result, Law 11 is the shortest and simplest of the Futsal Laws of the Game.
Futsal is governed internationally by the Futsal Laws of the Game, curated by IFAB, the same group that curates the Laws of the Game for Association Football (soccer). There are 17 Laws, although one of them (Law 11) simply states that there is no Offside. The basics of the game are identical to soccer, except in the dimensions of the court and markings, number of players and substitutions, the goal clearance, accumulated fouls, offside, the ball, and timing of the match. There are a few other differences, but they are mostly consequential to the other rule differences.
