Ice hockey rules in five minutes
Rules baseline: IIHF Official Rule Book 2026/27. NHL, NCAA, USA Hockey, and other competitions use distinct rink, roster, overtime, icing, fighting, review, and penalty procedures.
- Objective: score more goals by legally sending the puck completely across the opponent's goal line while defending your own goal.
- Players, rink, and equipment: teams normally skate with five players and one goaltender on the ice; the rink, goals, puck, sticks, skates, helmets, and protective equipment must meet IIHF standards.
- How play begins: a face-off at centre ice starts each period and follows every goal; other stoppages restart at the face-off spot prescribed for the cause and location.
- Possession and changes: teams control the puck through skating, passing, shooting, checking, and legal stick play, with substitutions generally permitted while play continues.
- Scoring: each valid goal counts once; kicking, high-stick contact, goaltender interference, offside, or an earlier whistle can prevent a goal.
- Length and winner: an IIHF game has three 20-minute stopped-time periods; competition regulations set overtime and shootout procedures if the score is tied.
- Main violations and penalties: offside and icing stop play, while tripping, hooking, slashing, interference, dangerous checks, misconduct, and fighting can reduce a team on the ice or remove a player.
- Restarts and penalties: face-offs restart play; minor, major, misconduct, game misconduct, and match sanctions determine player removal, penalty time, and whether a power play ends after a goal.
- Competition differences: NHL and IIHF rules differ on rink dimensions, icing details, trapezoid use, fighting, penalty shots, overtime, challenges, and review, with youth and college rules differing again.
