Can Zillions play card games?
In theory, but in practice this is hard, because Zillions was developed for board rather than card games, it doesn’t have any direct support for card games and doesn’t know anything about face-down (hidden) objects, hands, dealing, suits, runs/flushes/melds, etc. Also, it doesn’t have the numerical flexibility to handle scoring of hands. Someone has programmed the solitaire game Free Cell in Zillions (as if it were a board game), but games like Bridge are out of the question.
