The World Puzzle Federation is an association of legal bodies. The WPF follows the Olympic model if possible. Each country can be represented by one legal body only. In general the legal body has to be associated with puzzles. It could be a puzzle club, publisher of puzzles, newspaper et cetera.
Below are some additional criteria and information on the membership fee. Membership can be possible without meeting these criteria, but only as long as there are no applicants from the same country meeting all these criteria. For more information, or to request an application form, please contact the WPF's Director.
