Golf is an individual sport where players must hit the ball from the tee (starting area) to the hole by a stroke or a number of strokes. Golf is played on a course, which may consist of 9 or 18 holes. Each of these holes may have a variety of hazards to hinder the golfer including distance, bunkers (sandpits), water and rough ground. The aim of the game is to use the least number of strokes to hit the ball into the hole.
