What is Futsal?: Futsal is FIFA's official indoor soccer game. It is small sided (5 vs. 5), played on a smaller pitch (roughly basketball court sized) and with a smaller ball. The game is played on a flat indoor pitch with 2m height x 3m width (6.5'x10') goals and a size 4 ball with reduced bounce. The Game favors ball control and quick decision making. Futsal is normally played on an indoor court with a smaller, low-bounce ball. Unlimited substitutions are allowed, as players consistently are running on and off the court.
