Curling is a precision and team sport played on an ice rink.
Two teams of four participants compete against each other by sliding eight 20kg granite stones on a 45.5m long, 4.75m wide ice rink.
Once the launch has taken place, the other members of the team, provided with brushes, accompany each stone by acting on the ice surface to facilitate its advance or vary its direction by sanding or friction of the surface, but without touching the stone. Once all the throws have been made, points are awarded according to how close these stones are to the target marked in the centre at the end of the corridor. The stone which is closest to the center of the target counts one point; if the next one is from the same team, it counts two; and so on until the next one is from the opposite team. By this rule, always one team has to end the round with 0. In case there are no stones on the target it is considered 0-0. In a normal match eight to ten rounds are played.
At the end of the match the team with the highest score wins; in case of a draw, it is decided in an extra round. The team that wins a round must start the next round.
