When an ice hockey team is at full strength, it has six players. Usually, these are the goalie, the center, two wings and two defenders. However, sometimes players are removed to serve time for penalties. In addition, a goalie is occasionally pulled off the ice and replaced with another player.
All the players have specific jobs. A team scores by placing the puck in their opponent's goal, but the goalie's responsibility is to keep the puck out of this net. The defenders support the goalie by interrupting their opponents' play when it comes near the goal. The center and wings are primarily responsible for trying to score. However, when the other team has control of the puck, these players try to regain control of it.
