How NHL overtime works in playoffs: Sudden death, format, rules explained

The NHL Stanley Cup playoffs are currently in progress, and the overtime format has undergone significant change. No more three-on-three play, no more shootouts after five minutes of scoreless play, as happens during regular-season overtime. There is sudden death, but it could last a very long time.
One of those games wasn’t that long ago. In a game that lasted nearly four overtime periods, the Florida Panthers defeated the Carolina Hurricanes 3-2 in Game 1 of the 2023 Eastern Conference final. It came close to going to a fifth overtime, but Florida’s Matthew Tkachuk scored the winner with 12.7 seconds left in the period. It was the sixth-longest playoff game in NHL history.
Eight games in the NHL playoffs in 2025 have reached double overtime, including one game. Here’s a primer on playoff hockey overtime:
The teams go to the dressing rooms for 15 minutes while the ice is resurfaced if the score is tied after three periods. Overtime periods last 20 minutes or until someone scores. It’s five-on-five play (barring penalties). If no one scores in the first overtime, the process repeats and continues until someone scores. The teams change sides for each overtime period. The first overtime is the long change to get back to the bench.
The NHL Situation Room reviews all goals to make sure they are legally scored. In last year’s Stars-Avalanche series, the league upheld a no-goal call on an apparent score by Dallas’ Mason Marchment because referees ruled Matt Duchene had interfered with then-Colorado goalie Alexandar Georgiev. Duchene later scored the winning goal.
