Only one Super Bowl has gone to overtime; the New England Patriots defeated the Atlanta Falcons in overtime, 34-28, in Super Bowl LI.
In blowing a 28-3 lead, the Falcons remained one of the NFL teams that have never won a Super Bowl.
Super Bowl Overtime Rules
Super Bowl overtime rules are the same as NFL playoff rules: Both teams have the opportunity to possess the football. If the game is tied after each team’s possession, the next score wins.
For example, if the Cincinnati Bengals score a touchdown (plus an extra point) on their first possession of overtime against the Buffalo Bills, the Bills have one possession to score at least seven points.
If the Bills don’t score or score fewer than seven points, the game is over and the Bengals win.
If the Bills score eight points (i.e., a touchdown and two-point conversion), the game is over and the Bills win.
If the Bills score exactly seven points, the game continues and is played until the next score.
If the team that kicks off in overtime scores on special teams (safety or touchdown) or defense (safety or touchdown), the game is over.
If the game is tied at the end of one overtime period – or the second team’s first possession is still happening – a second overtime will begin where the first period left off, i.e., it’s treated like the transition from the first to second quarter (or third to fourth quarter) in a regular-season game.
