Rules That Change Your Odds
| Rule | Better | Worse |
|---|---|---|
| Blackjack payout | 3:2 | 6:5, which adds about 1.4% to the edge |
| Dealer on soft 17 | Stands | Hits |
| Number of decks | Fewer | More |
| Double after split | Allowed | Not allowed |
| Surrender | Allowed | Not allowed |
Basic Strategy in Brief
- Always split aces and eights.
- Never split tens or fives.
- Double 11 against most dealer cards.
- Stand on hard 17 or higher.
- Hit 12 to 16 against a dealer 7 or higher.
- Skip insurance, which is a poor bet.
A full strategy chart for your exact rules gets the edge down to about 0.5%. Practice in a free blackjack demo first.
Online Casino Black Jack: Live or Digital
Digital blackjack is fast and allows low bets. Live tables have real dealers and reshuffle on a schedule. Card counting does not work in practice online, because digital decks are reshuffled every hand and live shoes are cut deep.
Blackjack and Bonuses
Blackjack usually counts for 10% or less of wagering, and some bonuses exclude it completely. Real money blackjack players often do better without a bonus. Read the weighting table in the bonus terms first.
Side Bets to Skip
Perfect Pairs, 21+3 and similar side bets can add entertainment, but they have a much higher house edge than the main game. Keep them small or leave them alone.
21 Online and How to Win at Blackjack
