In ice hockey, a goal is scored when the puck partly crosses the goal line between the two goal posts and below the goal crossbar. A goal awards one point to the team attacking the goal scored upon, regardless of which team the player who actually deflected the puck into the goal belongs to (see also own goal). Typically, a player on the team attempting to score shoots the puck with his/her stick towards the goal net opening, and a player on the opposing team called a goaltender tries to block the shot to prevent a goal from being scored against his/her team.
The term goal may also refer to the structure in which goals are scored. The ice hockey goal is rectangular in shape; the front frame of the goal is made of steel tube painted red (or another color depending on the league) and consists of two vertical goalposts and a horizontal crossbar. A net is attached to the back of the frame to catch pucks that enter the goal and also to prevent pucks from entering it from behind. The entire goal is considered an inbounds area of the playing surface, and it is legal to play the puck behind the goal. Under NHL rules, the opening of the goal is 72 inches (180 cm) wide by 48 inches (120 cm) tall, and the footprint of the goal is 44 inches (110 cm) deep.
The object of the game of hockey is to score more goals than the opposing team. Goaltenders and defencemen are concerned primarily with keeping the other team from scoring a goal, while forwards are primarily concerned with scoring goals on the other team. Forwards, of course, have to be defensively responsible and defencemen also need to press offensively, and it is not unknown for goalies to attempt to position the puck for a counterattack, or even attempt to shoot against an unguarded net.
For a goal to be scored, the puck must entirely cross the goal line between the posts and under the crossbar of the goal frame. A goal is not allowed under any of the following conditions:
Additionally, in many leagues, a goal does not count if a player from the attacking team has a skate or stick in the goal crease before the puck. The NHL abolished this rule starting in the 1999-2000 season after the disputed triple-overtime goal in the 1999 Stanley Cup Finals. Brett Hull of the Dallas Stars scored the series-clinching goal against the Buffalo Sabres. There are those who believe that video replay shows Hull's skate in the crease prior to the puck.
