thats the beaty of the system it doesnt matter if you play with 1 deck or 8 decks. Granted it takes longer for the system to work but you just have to play till you get a positve value and then start betting larger ammounts. But indeed only works if the dealer doesn't suffle the decks but I think that doesn't happen alot.

Not in the mood for cheese?
That excuse has more holes than a slice this fine Gorgombert!
