The purpose of the game is to score points by getting stones closer to the house center, or the “button”, than the other team’s stones. Players from either team alternate in taking shots from the far side of the sheet, each player throws two stones per end. An end is complete when all eight rocks from each team have been delivered, a total of sixteen stones. Once a stone has been thrown, teammates may sweep in front of the stone to modify the trajectory or to increase the total distance traveled by the stone.
