What is the International Puzzle Party (IPP)?

The purpose of the International Puzzle Party is to provide an annual forum for serious puzzle collectors for the exchange and sale of mechanical puzzles, books and related items, as well as for fun and fellowship. In short: puzzling fun for puzzle enthusiasts. International Puzzle Parties have been held almost every year since 1978. IPP's are usually organized in three-year cycles in the USA, the Far East, and Europe.

Attendance at any International Puzzle Party event is by personal invitation only, from the hosting team. Thus, all web sites for individual IPP's are password protected.

Invitees are requested not to disclose the location or dates of future IPPs.
