Ice hockey is a team sport played on ice by two teams. The participants skate over the ice at great speeds while wearing ice skates on their feet. They have hockey sticks in their hands, which they use to push, shoot, or pass a puck across the rink. Goaltenders attempt to stop the players from scoring by firing the ball into the net. There are three main types of shots in ice hockey: slapshots, wrist shots, and passes. The first game of ice hockey was played in Montreal, Quebec, in 1875. It was called "soccer" at the time because both American football and European soccer were popular sports in the era before basketball became popular. Ice hockey has rules different from soccer or American football. For example, there is no offside rule; instead, each player is assigned a side he or she must stay on during a play. There are also no downs, so every series of plays ends with the ball being put into play again. Finally, there is no goal line; instead, each team's goal is a horizontal plane located between the nets where the ball may be placed. In Canada, ice hockey is the most popular winter sport. In fact, it is so popular that the word "ice" is sometimes used as a verb meaning "to score." People everywhere enjoy watching ice hockey games on television. The best ice hockey players in the world make millions of dollars playing this sport.
