World Minigolfsport Federation (WMF), a member of AGFIS, organises World Championships bi-annually (on odd-numbered years), while the
World and European Championships have so far never been arranged on MOS courses (which are popular in USA and UK, and were approved by WMF for competition use only a few years ago). International competitions are typically arranged on two courses of 18 holes, of which one course is eternite, and the other course is usually concrete, less commonly felt. In the future, the WMF is expected to use also MOS courses in international championships – which will give American and British players a chance to show their skills on their own traditional course types.
The most prestigious MOS minigolf competitions in the world are US Masters, US Open, British Open, World Crazy Golf Championships and the World Adventuregolf Masters.
