Golf is a precision club-and-ball sport in which competing players (golfers), using many types of clubs, attempt to hit balls into each hole on a golf course while employing the fewest number of strokes. Golf is one of the few ball games that does not require a standardized playing area. Instead, the game is played on golf "courses", each of which features a unique design, although courses typically consist of either nine or 18 holes. Golf is defined, in the rules of golf, as "playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules". Golf competition is generally played for the lowest number of strokes by an individual, known simply as stroke play, or the lowest score on the most individual holes during a complete round by an individual or team, known as match play.
