Abstract: One embodiment of a Turing complete set of game components in the form of a deck of playing cards, each card (110) having at least one divinatory element illustrated on its playing face (112). In other embodiments, the game components may take other forms, including, but not limited to components for board, dice or tile games. Additionally, the game components may be simulated in different types of non physical ways, including, but not limited to electronic games, video games, computer games, or interactive network games. The embodiments described and shown have the advantage over prior art of being able to simulate a universal Turing machine in a two player game for a finite period of time within a finite volume of space, which is sometimes referred to as a tabletop game.
