There is no offside rule in the sense that the term is usually used in soccer and Ice Hockey. It is not necessary that the defenders have one or more men between the ball and the basket.
However, there are other rules to regulate player positioning. The over-and-back rule requires that once the attacking team has moved the ball into their opponents' half of the court, they may not move it back to their half again. This concentrates the action nearer to the basket. The "no camping" rule declares that no defending player may spend more than three seconds within the lane at a time, so the defenders can't just "camp out" under the basket to prevent shots on it. Hence all the inefficient-looking jockeying for position under the basket.
Yes, there is offsides in Olympic hockey. Olympic rules are basically the same as NHL rules, except for icing. Icing in Olympic hockey is automatically blown down as icing whereas in the NHL, the team that iced the puck must beat the other team to the puck for it not to be icing.
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.
Sports such as ice hockey, Field Hockey, American and Canadian football, soccer and Rugby have an offside rule.
no because the pitch is too small
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.
