Teams are made up of four players. Starting in the Hack, each player in the team slides a 20kg granite stone down a sheet of ice and have it stop nearer the centre of a target (the "House") than your opponent’s stone.
Stones are intentionally rotated slightly when delivered and will curve a foot or two ("curl") in the direction it is rotated.
Two sweepers, as directed by the skip (the person in charge of the team), use brushes to sweep the ice in front of the curling stone so that the ice is smooth and the stone goes further and straighter. A normal game lasts about two hours.
