How to read the format
- Identify the competition: NHL, IIHF, NCAA, youth, or another league.
- Check whether the game is regular season, tournament group play, knockout, or playoffs.
- Apply the overtime strength and period length for that stage.
- If the format allows a shootout, use it only after the overtime period fails to decide the game.
- If it is playoff sudden death, continue full overtime periods until a legal goal is scored.
