There are two national associations, the English Tiddlywinks Association (ETwA) and the North American Tiddlywinks Association (NATwA) (the Scottish Tiddlywinks Association having disbanded in the late 1990s).
These organisations are responsible for conducting tournaments and maintaining the rules of the game (which actually differ only slightly between the two organisations; the NATwA rules are based on the ETwA rules).
 International competition is overseen by the International Federation of Tiddlywinks Associations (IFTwA), though in practice it is rarely called upon to intervene.
