Minor penalty: When given a minor penalty, the penalized player must sit in the penalty box for two minutes, and his team must play with one less player. This is known as a power play for the team with the extra player. Should the team with the power play score before two minutes are over, the penalized player gets to return to the ice and the teams are at equal strength. Minor penalties include: boarding, charging, elbowing, high-sticking, holding, hooking, interference, roughing, slashing, spearing and tripping.

Major penalty: When given a major penalty, the penalized player must sit in the penalty box for five minutes and, depending on the situation, his team might play with one less player. These offenses include more serious penalties: butt-ending, checking from behind, fighting, high-sticking, and spearing. Depending on the severity of the offense, these penalties are sometimes accompanied by a game misconduct, removing the player from the game.

Match penalty: For deliberately injuring an opponent, the offending player must sit out the remainder of the game. The team must play short-handed, with the severity of the injury determining the length of the penalty.

Misconduct Penalty: Usually called against a player who becomes excessively abusive in language. Although the player must sit out for ten minutes, the team does not play short-handed.

Game Misconduct: The suspension of a player for the balance of the game, but the penalized team does not have to play short-handed.

Referee: The referee supervises the game, calls penalties, determines goals and drops the puck for face-offs at center ice to start each period.

Linesmen: Two linesmen are used per game and they call offsides, offsides passes, icings, and handle all face-offs but those at center ice. They do not call penalties but can recommend to the referee that a penalty be called.

Goal judges: A goal judge sits behind each net and indicates when a goal has been scored by turning on the red light just above his station. The referee can ask his advice on disputed goals, but the referee is the final authority and can overrule the goal judge.
