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.
