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.
There are 3 periods in a hockey game. If the game is tied after 3 periods, there is an overtime. If that doesn't end in one team scoring, there can be a shootout or as many ov â¦ ertimes as needed.
