Understanding Ice Hockey Overtime Rules

Introduction: Why overtime rules matter
Overtime rules determine how tied ice hockey games are resolved and shape tactics, player selection and fan experience. From regular-season finishes to high-stakes play-offs, different overtime formats influence scoring chances, injury risk and the balance between team strategy and individual skill. Understanding the common formats used by major leagues helps supporters and players appreciate how and why games are decided.
Main body: Common formats and key details
NHL regular season: 3-on-3 then shootout
In the National Hockey League (NHL) regular season, tied games proceed to a five-minute sudden-death overtime played 3-on-3. The open ice produced by fewer skaters tends to create more odd-man rushes and scoring chances. If no goal is scored in overtime, a shootout follows: each side selects three shooters, and if still tied after those attempts the shootout continues in sudden-death rounds. Teams may change their goaltender before the shootout.
NHL play-offs: 20-minute sudden-death periods
Play-off hockey uses a different approach. Overtime consists of full-strength 20-minute sudden-death periods (5-on-5), repeated as necessary until a goal is scored. There are no shootouts in the play-offs, so games can extend through multiple overtime periods and become tests of endurance, depth and goaltending.
Other competitions and variations
International and junior competitions follow formats set by governing bodies (for example the IIHF) and can vary by tournament stage. Some events use shorter overtime with a shootout in group stages, then longer overtime in elimination rounds. Domestic leagues outside the NHL may also adopt their own procedures, balancing scheduling concerns with competitive fairness.
Conclusion: Implications and outlook
Overtime rules significantly affect game flow and strategy: coaches shorten or extend lines, teams prioritise speed and puck control in 3-on-3, while play-off overtime rewards depth and stamina. Fans often favour the excitement of 3-on-3 and shootouts in the regular season, but traditionalists argue that play-offs should be decided on the ice without shootouts. Leagues continue to review formats to balance entertainment, safety and sporting integrity, so further adjustments remain possible.
