While OFL play is very similar to other styles of the game we do have slightly different rules.
Each team has a team captain. The two captains will confer with each other and the Commissioner on controversial situations. If the two captains cannot agree on a course of action, the Commissioner will rule on the play.
In the event that teams have unequal numbers the following rules apply:
At the end of the game if one team is losing by more than 8 points, that team is allowed a single "X-point play", either a final "Hail Mary" pass after their final fourth down (i.e. a "fifth down") or, assuming they have scored a touchdown on the final possession, an "X-point conversion" attempt. In either case, the "X-point play" is worth however many points it takes to tie the game.
Teams that are down by 8 points or less must try to win or tie the game the old fashioned way.
The Line of Scrimmage can be set by players from either team. A standard yellow penalty flag is used to mark the current spot of the ball and the subsequent line of scrimmage.
Technically the defense is responsible for spotting the ball - this becomes important in two-minute drills or other 'hurry up' play. Not moving the flag to the new spot in a timely manner is a Delay of Game penalty.
