The team sports of Curling (2events) and ice hockey (2 events) are played on ice rinks. In curling, each team slides large polished stones across the ice towards a circular target. Points are scored by whichever team leaves one of their stones closest to the centre of the target. The team with the most points after ten "ends" is the winner. In ice hockey, players carry ice-hockey sticks and try to score by using them to hit a small, flat object called a "puck" into the opposing team's goal.
