Different! Definitely different!
Usually, 5 dice are on a game, but only 2 are used on any roll. Therefore, if you replace the side of each dice used in a roll with a card numbered 1 thru 6 respectivley, you should only have a choice of picking 2 cards out of 12. Not 72.
I've never heard of this type of game before, and I've been around a few different joints in a lot of countries!
I would think that if the # of cards numbered 1 thru 6 were multiplied by any number, the odds would still be the same?
Example - 72 cards(12 sets of cards 1 thru 6)

144 cards(24 sets of cards 1 thru 6)
Same odds? Help from mathematicians would be good at this point!
Maybe the shuffler is only set to operate with 72?
