Hockey 101: The Rink
The most important lines are the red line (which runs across the center of the ice) and the blue lines (which are parallel to the red line and are painted 73' from each end of the rink). The blue lines divide up the ice into three zones. Each team plays from one side of the ice, and the area behind a team's blue line is called its defending zone. The area behind the opposing team's blue line is called the attacking zone. Finally, the area between the two blue lines is called the neutral zone.
Hockey 101: The Players
There are three basic kinds of players: forwards, defensemen, and goaltenders (goalies). Unless a team is shorthanded due to a penalty or overtime, each team will have six players on the ice including the goalie. Three forwards line up at the front of the team, and they are (from left to right) the left wing, the center, and the right wing.Hockey 101: Regulation Time and Overtime
Each game consists of three periods of twenty minutes each. The players get about fifteen minutes of rest between periods. In the regular season, if the game is tied at the end of regulation time (the end of the third period), the teams almost immediately go into overtime, which is an extra five minutes of playing time.So There's your Hockey 101.
