Curling is played on a long, narrow sheet of ice with a marked target area, called the house, at each end. Two teams, each with four players, take turns sliding 42-pound granite stones to the far side of the ice sheet. The objective for each team is to get its stones closest to the center button of the house.
Players vigorously sweep the ice in front of the stone to keep it moving. The friction caused by the sweeping polishes the ice briefly, which makes the stones travel farther and straighter.
Each curling match is divided into ten ends. Each end includes both teams delivering all of its stones (eight stones per team). After all the stones have been delivered, the team whose stone is closest to the button gets a point. Additional points are scored by other stones in the house that belong to the same team, at one point per stone.
The team with the most points after the tenth end is the winner.
