The World Minigolf Sport Federation (WMF) is the internationally recognised governing body for the sport of miniature golf, or also known as minigolf, crazy golf, or putt-putt. It takes after the parent sport of golf, with the difference that it focusses solely on the putting aspect. The playing area is also much smaller with the series of holes normally a multiple of nine. The distance to the hole is usually within ten yards and the surface area is either concrete or artificial turf. The aim for any player is to score the lowest number of points. The layout of each course is normally characterised by non-traditional putting lines that include moving obstacles like windmills, bank shots, tunnels, and ramps.
Hamburg in Germany was the first documented location for a minigolf course built in 1926. The game also then spread to Sweden and Great Britain. The Swedish Minigolf Federation was founded in 1937 and is the oldest minigolf federation in the world. It was in the 1960s that felt was used as a playing surface as it allowed for play in wet weather. The rain would soak though the felt into the ground, while the surfaces of beton and eternite created pools of water stopping the ball from rolling.
The role of WMF is to develop and grow minigolf as a competitive sport. At the same time, the attraction of the game being a fun leisure activity further generates participation and growth.
