The NHL‘s Stanley Cup playoffs are underway, bringing a major change in the overtime format.
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.
Witness the 2023 playoffs. The Florida Panthers beat the Carolina Hurricanes 3-2 in Game 1 of the Eastern Conference final in a game that lasted nearly a full four overtime periods. 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.
So far in the 2025 NHL playoffs, 18 games — including Game 1 of the Stanley Cup Final — have gone to overtime, including three double-overtime games.
Here’s a primer on playoff hockey overtime:
If the score is tied after three periods, the teams go to the dressing rooms for 15 minutes while the ice is resurfaced. 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.
Eight Stanley Cup Final games have gone to the third overtime. The Edmonton Oilers were part of the longest game when Petr Klima scored at 15:13 of the third overtime for a 3-2 win against the Boston Bruins in the 1990 Final.
