Olympic ice hockey games are played in three periods of 20 minutes each, just like the NHL.

A few quick extras that people often wonder about:

  • Total regulation time: 60 minutes of game clock (3 × 20-minute periods).
  • Breaks: There are intermissions between the periods for rest and ice resurfacing.
  • Overtime: In knockout or medal rounds, if the game is tied after three periods, it goes to overtime, with specific formats (3-on-3 or similar) depending on the stage of the tournament.
