Ice hockey is a contact winter team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It is one of the fastest team sports on ice belonging to a small group of four ice skating team sports which now includes bandy, ringette, and rinkball. 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.
