Futsal is a growing sport similar to soccer that is typically played 5v5 indoors on a hard court surface with an out-of-bound goal and touch lines, smaller goals, and slightly modified Laws. It is different from "Indoor," where walls are typically present that the ball can be played off of. Both are fun to play; however, Futsal tends to be more like an outdoor game, requiring better passing and control to keep the ball in play.
There are typically one or two Futsal referees used for each game who travel the touchlines and stay out of the way of play. For the youth game, a single referee is normal.
The game is growing here in Montana, with leagues forming and tournaments each year.
