Passing rules in the IFL, are the same as outdoor NCAA Football in which receivers must have one foot in bounds. A unique exception involves a ball that hits the wall in flight. A forward pass that rebounds off the wall is a live ball and is in play until it touches the playing surface.


  • Overtime is conducted the same as in NCAA Football. Each overtime period consists of a two-possession series with each team getting one possession on offense and one on defense. The team on offense will always start at the designated plus 20-yard line (unless relocated by a penalty). 
  • The team that scores the most points during regulation and overtime wins the game. If the game is still tied after an overtime period, there will be another overtime period.
  • Beginning with the third overtime period, teams that score a touchdown must attempt a two-point conversion.
