Curling or the Roaring Game is a Scottish national game akin to bowls played with stones on ice, said to have been introduced from the Low Countries in the 16th century. The game is played by two teams of four players, each player using two curling stones and playing them alternately with his opposite number. The player throws the stones over a 40 yard course to concentric circles, known as the house, cut on the ice, known as the rink. The objective being to end the game with one's stones as close as possible to the centre circle known as the tee, or in the USA and Canada as the button. Research Curling
