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 puzzles, books and related items, as well as for fun and fellowship. In short: puzzling fun for puzzling 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. This is why the web sites of future IPP's require a password. Please do not advertise future IPP's to people who are not invited; do not even mention the exact locations nor dates.


There is now a forum available for attendees to discuss past and future IPPs, as well as general puzzle discussion of interest to attendees. Please use your IPP username and password to access the forum; to use the forum, you will also need to create a separate forum username.
