was the same as in the NFL with the addition of a drop kick field goal worth four points during normal play or two points as a post-touchdown conversion. Blocked extra points and turnovers on two-point conversion attempts could be returned by the defensive team for two points. A rouge-kickoff downed in the end zone was worth 1 point to the kicking team; a rogue-kickoff being when the kick returner is caught in his own end zone. A free kick recovered in the end zone by the kicking team was considered a touchdown. Timing A game consisted of four 15-minute quarters with a halftime intermission 20 minutes in length. The clock typically only stopped for time-outs, penalties, injuries, and official clarifications. Further stoppages occurred for incomplete passes and out of bounds during the final 90 seconds of the second and fourth quarters. A mandatory official's time-out, called a promotional timeout, was assessed after the first and third quarters and is 90 seconds in duration. Another mandatory official's time-out, called a warning period, was assessed with 90 seconds to play at the end of each half. The game could also be stopped for further promotional time-outs but not exceed 90 seconds per league rules. Overtime rules Each team received one possession from the 25-yard line to try to score. If one team outscored the other on the possession, the game was over. If still tied after an overtime possession, then each team received a new possession from the 25-yard line to try to score.
