Blackjack: Odds & Simulated House Edge
Blackjack has the lowest house edge on the floor when you play basic strategy. Our table uses liberal rules — the dealer stands on soft 17, you can double after splitting, and late surrender is allowed — which put the edge around 0.26%, even lower than the ~0.5% you'll see where the dealer hits soft 17.
The win, push, bust, and blackjack rates below come from playing full hands with our engine — hitting, standing, doubling, splitting, and surrendering exactly per basic strategy — then letting the dealer play and settling every hand.
