Each NHL game features 60 minutes of playing time, broken down into three 20-minute periods. The league also mandates a 17-minute intermission after the first and second periods to flood and ice and provide the players with a rest period.
NHL games last for 3, 20-minute periods, with 2 15 minute intermissions between them. With stoppages in play, injuries, fights, and penalties, the average game take between 2.5 and 3 hours. If it goes into overtime, it is 5 minutes, followed by a shootout if a goal is not scored in those five minutes.
