Chess Dungeon is chess-without-limits, created by Thomas P. W. James. Two or more people may play. Chess Dungeon applies the orthodox game language of Chess to an emergent playing space. It has no "board" as such - the playing area and the pieces that may be played are determined by custom, collectable playing cards. Each card may serve as either tiles of the "board" ("Land"), or be tabled ("Declared") to place the Chess pieces upon a Land card. Two cards are played per turn until players' cards run out. In this way players determine the size of the game (thus its approximate duration) by agreeing to how many cards may be played in a game. Players may also agree to different piece limitations and so forth. The aims are: be the last player alive (not checkmated), avoid stalemate, and win cards from other players in order to gain points.
