Ice hockey is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. In ice hockey, two opposing teams use ice hockey sticks to control, advance, and shoot a closed, vulcanized, rubber disc called a "puck" into the other team's goal. Each goal is worth one point. The team which scores the most goals is declared the winner. In a formal game, each team has six skaters on the ice at a time, barring any penalties, one of whom is the goaltender. Ice hockey is a full contact sport, and is considered to be one of the more physically demanding team sports. It is distinct from field hockey, in which players move a ball around a non-frozen pitch using field hockey sticks.
