House Advantage with Multiple Number of Decks. The number of 52 card decks in a game of blackjack influences the house edge. In some cases, the odds increase in favor of the casino when more decks are used. The advantage edge can be as much as 1% towards the casino and this is a big number in terms of odds over the long term. For example, the following blackjack table shows the effect that the number of decks has on the house edge against a basic strategy player with H17 and DAS. (These are Total-Dependent house edges.) Notice that as the number of decks increases, the house edge increases incrementally up to 0.64% for an eight-deck game. Full deck resolution divides by the number of full decks but can certainly be a non integer divisor. If you are making estimates to half deck accuracy you divide by the number of full decks to half deck accuracy. The difference between half deck estimates at full deck and half deck resolution: 2.5 decks left or 5/2 deck estimation.
