What other game is comparable to Theatrix but uses playing cards as its randomiser?
Diceless role-playing game A diceless role-playing game is a role-playing game which is not based on chance: it does not use randomisers to determine the outcome of events in its role-playing game system. The style of game is known as "diceless" because most games use dice as their randomiser; some games such as "Castle Falkenstein" use other randomisers such as playing cards as substitutes for dice, and are not considered "diceless".
Transcendental chess Transcendental chess is a chess variant invented in 1978 by Maxwell Lawrence. Chess960 (Fischer Random Chess) is similar but has fewer starting positions. In transcendental chess the beginning positions of the pieces on the back row are randomly determined, with the one restriction that the bishops be on opposite-colored squares. There are 8,294,400 such positions in total. In Chess960 there are 960 possible starting positions, but that is because the king must be located between the rooks and both sides must have the same starting position. In transcendental chess there is no such rule so the position of one side can be any of = 2880. There is no castling. On the first turn a player, instead of making a move, can transpose any of two pieces on the back row.
