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's 3-20 minute periods. There's 4 t.v. timeouts during each period for about 90 seconds each. Also 2-15 minute intermissions between the first 2 periods. An average Hockey game is about 2 and a half hours. 3 periods of 20 minutes clean time, which means that the clock stops every time the play is stopped. minis/welps will sometimes play 4 periods of 15 minutes. so either way, the playing time lasts 60 minutes.
