Indoor football is a term used to describe several variations of American football which are played indoors. It is important to note that NFL or College games played in locations such as the Astrodome or the Superdome do not qualify as Indoor football as they are using a standard size playing field. The rules of Indoor football are specifically designed to allow for play in a smaller area which would normally be used for a sport such as Basketball or Ice Hockey. An Indoor football playing season is typically scheduled to begin in mid to late Winter and continue to the middle of Summer.
