damn i have no idea....though it will still take out a card even if you don't pick one and just clicked on one of the eyes. one thing i noted was that the king of clubs wasn't in the first set but in the second....it might have something to do with that, infact none of the cards in the first set show up in the second one!!!!.....it eliminates all the cards in the first set ha ha.
