Golf is a club and ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible.
The game is played on a course with an arranged progression of 18 holes. Each hole on the course must contain a tee box to start from, and a putting green containing the actual hole or cup (4.25 inches in width). There are other standard forms of terrain in between, such as the fairway, rough (long grass), sand traps, and hazards (water, rocks, fescue) but each hole on a course is unique in its specific layout and arrangement.
Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, known as match play. Stroke play is the most commonly seen format at all levels.
