Golf - Every game of golf is based on playing a number of holes in a given order. A round typically consists of 18 holes that are played in the order determined by the course layout. On a nine-hole course, a standard round consists of two successive nine-hole rounds. A hole of golf consists of hitting a ball from a tee on the teeing box (a marked area designated for the first shot of a hole, a tee shot), and once the ball comes to rest, striking it again. This process is repeated until the ball is in the cup. Once the ball is on the green (an area of finely cut grass) the ball is usually putted (hit along the ground) into the hole. The idea of resting the ball in the hole in as few strokes as possible may be impeded by various hazards, such as bunkers and water hazards.
