Miniature golf is also known as mini golf or crazy golf and is an off shoot of the sport golf. Mini golf focuses solely on putting. It is played on a course of holes (in multiples of 9) like regular golf, but the holes are a much shorter length, usually only about 10 yards. The holes usually use an artificial putting surface (carpet, astroturf or concrete) and require non-traditional putting lines (bank shots) to get through artificial obstacles (tunnels, tubes and ramps) and moving objects (windmills or swinging posts).
The earliest mention of a mini golf course was in June 1912 in The Illustrated London News. In 1922, inventor Thomas McCulloch Fairbarin, a golf fanatic, revolutionized the game by formulating artificial green. The “green” was a mix of cottonseed hulls, sand, oil and dye. This artificial turf allowed the game to be played anywhere in the world.
The U.S. dedicated the second Saturday in May as National Miniature Golf Day. The World Minigolf Sport Federation (WMF) is headquartered in Goteberg, Sweden.
