Blackjack Rule Variants
Two tables that both call themselves “blackjack” can differ by more than a full percentage point in expected cost — it all comes down to decks, soft-17, payout and surrender. Pick a rule set below to see its expected value (EV), house edge and basic-strategy notes.
How rules change the house edge
The anchor is 8-deck S17 at 0.71% house edge (99.29% RTP). From there, each rule moves the number in predictable increments:
- Blackjack pays 6:5 instead of 3:2 — adds about 1.4% to the house edge, by far the most expensive rule a casino can impose.
- Dealer hits soft 17 (H17) instead of standing (S17) — costs the player about 0.2%.
- No double after split (DAS) — about 0.14% worse for the player.
- Fewer decks help: a single deck is roughly 0.48% better than an 8-deck shoe.
- Late surrender available — saves about 0.08%.
