Why Rule Variations Matter
How Rules Affect the House Edge
Different rules can increase or decrease the casino’s advantage by 0.1% to 2% . Smart players seek tables with player-friendly rules.
| Rule Variation | Effect on House Edge |
|---|---|
| 6 decks instead of 8 | -0.02% (better) |
| Dealer stands on soft 17 | -0.22% (better) |
| Dealer hits on soft 17 | +0.22% (worse) |
| Double after split allowed | -0.14% (better) |
| Late surrender allowed | -0.08% (better) |
| Blackjack pays 6:5 instead of 3:2 | +1.39% (much worse) |
Critical: Always avoid 6:5 blackjack tables – they dramatically increase the house edge .
