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.
Olympic ice hockey games run the same length as NHL games: 3 twenty minute periods with 2 ten minute intermissions. A game can run as fast as 90 minutes, or as long as 3 hou â¦ rs, in some cases.Three 20 minute periods plus two ten minute intermissions equals 80 minutes. First and foremost, hockey does not have quarters. It is played in three sections known as periods. Secondly, the length of each period is unique to the level of hoc â¦ key that is being played. For a game of professional hockey (i.e. NHL, ECHL, AHL, the Olympics) the periods have a clock time of twenty minutes.
