NHL Playoff Overtime: Rules, Longest Games, and 2026 Highlights

The NHL’s Stanley Cup playoffs introduce a thrilling twist to the overtime format, creating an atmosphere of suspense and excitement. Unlike the Olympics, where 3-on-3 overtime is the norm, the NHL returns to a classic 5-on-5 setup during the postseason, intensifying the competition where every goal matters. As the stakes rise, the absence of shootouts after five minutes of scoreless play leads to sudden death scenarios that can stretch on for an extended duration.

This postseason has already seen a flurry of action, with 18 overtime games, including three that extended into double overtime. Notably, Game 7 of the Montreal-Buffalo series marked the latest addition to this list, showcasing the high-pressure environment of playoff hockey.

When the clock hits zero after three periods, teams retreat to their dressing rooms for a crucial 15-minute intermission while the ice is resurfaced. Each overtime period lasts 20 minutes of uninterrupted play, with teams engaging in 5-on-5 action unless penalties come into play. If the first overtime ends without a goal, the process repeats, with teams switching sides for each new period. This strategy adds an element of fatigue and strategy, especially during the long change in the first overtime.

The NHL Situation Room plays a pivotal role in ensuring the integrity of the game, reviewing all goals to confirm they are scored legally. This was evident in critical moments like the goal that concluded Game 4 of the Anaheim-Edmonton series and the overturned goal in Game 4 of the Vegas-Utah series.

Several standout moments have defined the overtime landscape in this year’s playoffs. On May 18, Alex Newhook clinched victory for the Canadiens with a goal at 11:22 of the first overtime, eliminating the Sabres in Game 7. Just days earlier, Brett Kulak netted the winner at 3:52 of the first overtime, allowing the Avalanche to oust the Wild in Game 5.

Other notable overtime efforts include Pavel Dorofeyev’s game-winner for the Golden Knights just over four minutes into the first overtime against the Ducks, and Jackson Blake’s decisive goal at 5:31 of the first overtime to sweep the Flyers. The intensity of these moments exemplifies the exhilarating unpredictability of playoff hockey, where every shot can change the course of a series.

As the playoffs progress, fans can expect more nail-biting overtime battles, with the potential for history to be made. The longest games in Stanley Cup Final history have already captivated audiences, including a memorable encounter in 1990 when Petr Klima scored at 15:13 of the third overtime, leading the Oilers to a 3-2 victory over the Bruins.
