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.
Current members
All current members can be found at WPF members.
How to join
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.

Players Eligibility Rules
The rules adapted in September 2026 govern who may represent a country in competitions organised under the auspices of the World Puzzle Federation. This policy is intended to balance three goals: 1) fair access for genuine citizens of a member country or unfederated country, 2) administrative clarity for organisers and prospective participants, 3) clarity around exceptional circumstances.
