If we assume a standard game in which is a 6-deck shoe is used, dealer stands on soft 17, the player may double on any first two cards, the player may split up to four times, and the player may double after splitting, the house edge with basic strategy is only 0.4062%. The house has an advantage in every single game – that is how casinos make their money – but not all games are created equal.įortunately, blackjack has one of the lowest house edges of any casino game. Flip it around, and it is the amount you would expect to lose. The house advantage, or house edge, is the percent of a player’s initial bet that the casino will expect to make in the long run.
