The Olympic curling events take place over a series of round robin events. The tournament format is similar to the kind of rounds that we see in Basketball tournaments. Each game consists of ten âends,â which are similar to sets in tennis or innings in baseball. In each end, each team member throws two stones. If there is a tie after the ten ends, game play continues until the tie is broken. Gameplay is typical reserved to 73 minutes per team for the ten ends with 2 timeouts. If extra ends are played, they are limited to 10 minutes per team with an extra time out. In curling, teams slide a polished granite stone over a rectangular sheet of ice. The ice sheet has a pattern on it (called the house). The goal is to place your teamâs stones closer to the target than your competitors.
