NHL Overtime Rules In Playoffs, OT Format And Longest Games

Updated April 20, 2026, 10:39 p.m. ET

The NHL’s Stanley Cup playoffs are underway, meaning a major change in the overtime format.

Unlike the Olympics, where 3-on-3 overtime is played even in the gold medal game, the NHL switches things up in the postseason when the games matter more.

There won’t be any more 3-on-3 play. It’s 5-on-5 instead. There won’t be any more shootouts after five minutes of scoreless overtime play. There is sudden death, and it could last a very long time.

In the 2025 Stanley Cup Final between the Florida Panthers and Edmonton Oilers, three of the first four games went to overtime, including one double-overtime game. Overall in the 2025 NHL playoffs, 20 games went to overtime, including four double-overtime games. This postseason, there has been one overtime game.

Here’s a primer on playoff hockey overtime:

How does OT work in NHL playoffs?

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 5-on-5 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.
