The Decktet is a deck of cards with suits, ranks, and named images. It is structurally unlike ordinary poker and tarot decks, meaning that you can do different things with it. There is a free print-and-play version of the game system available under a Creative Commons BY-SA-NC license. There are dozens of games for it designed by various people. There is also a supporting book which collects together many of the games and includes related articles.
