How Does NHL Overtime Work?
NHL regular season overtime rules mention that the team plays a sudden death of 5 minutes with three skaters and a goaltender on each team.
The OT was implemented for every game from 1921 to 1942. However, it was terminated in the 1942-43 season due to wartime train restrictions.
In 1983-84, overtime was reintroduced for the regular season. The time was reduced to five minutes and sudden death was implemented. Still, the clear winner could not be decided if none of the teams scored in the OT.
Thus, a shootout was added to the regular season overtime in the 2005-06 season. The team that secures the highest score in the shootout is considered the winner of the game.
The rules for OT were modified before the 2015-16 season. Instead of five skaters and a goaltender, it stated that only three skaters and a goalie can be on the ice.
The overtime is shorter in the regular season as compared to the playoffs. Eighty-two games are scheduled densely for each regular season in a round-robin format.
