Blackjack Rule Variants

Every casino runs a different mix of rules. Pick a common table type below to see its exact house edge and what makes it different.

How the house edge here is calculated

Each variant's edge composes a baseline house edge with the published effect of every rule that differs from that baseline — deck count, dealer soft-17 behavior, double after split, surrender, and blackjack payout ratio — the same engine that powers the house edge calculator. Open any variant to see its exact rule set and try it in the calculator.
