- If a regular season NHL game is tied after three periods (20 minutes each), the two teams play a sudden-death five minute overtime period to try to break the tie. In the playoffs, however, the game keeps going until someone scores. The longest overtime game in playoff history was in 1936, when the Detroit Red Wings finally beat the Montreal Maroons in the sixth overtime period. They basically played almost three full games in one night.
- Mario Lemieux and Wayne Gretzky are the only players to be named MVP of three NHL All-Star games.

- Bernie Geoffrion is credited with bringing the slapshot to the NHL in 1951. He was given the nickname “Boom Boom” because his shot was so hard and fast.
- The first goaltender to regularly wear a face mask during a game was Montreal's Jacques Plante. A shot broke his nose in 1959 and he decided to wear one ever since. He was made fun of at first, but now every goaltender wears a mask. Thanks to him, many broken bones and stitches have been avoided.

- The World Hockey Association (WHA) was a rival hockey league in existence from 1973 to 1979. Hockey legends Gordie Howe, Bobby Hull, and Wayne Gretzky all played in the league, but it couldn't compete with the NHL. Four current NHL teams came over from the WHA — the Edmonton Oilers, Hartford Whalers (now Carolina Hurricanes), Quebec Nordiques (now Colorado Avalanche), and Winnipeg Jets (now Phoenix Coyotes).
