Metapontum is a hexagonal chess variant. In this game, players do not fight each other but cooperate to reach a certain position, following the philosophy of the inventor, Hans Theo Frenkel. The Metapontum website (in Dutch) gives information on the game (including rules, pictures), the Metapontum organization, and the different Metapontum sets, with information on how and where they are made, and how to order them.
