What is curling
Curling is a olympic team sport played on a rectangular sheet of carefully prepared ice by two teams of four players each. Teams alternate turns at sliding heavy, polished granite stones down the ice towards the target area called the house.
Two sweepers with brooms accompany each rock and use timing equipment and their best judgement along with direction from their other teammates to help direct the stones to their resting place. The complex nature of stone placement and shot selection has led some to refer to curling as "chess on ice".
