American Blackjack
0.45% edge
American Blackjack
0.45% edgeBasic Strategy Tips
- 1.Same basic strategy as Classic applies since the dealer peeks.
- 2.Stand on hard 17+. Hit on hard 11 or lower.
- 3.Double down on 11 vs dealer 2-10.

- –Dealer peeks for blackjack, so you never lose extra bets to a dealer natural.
- –Late surrender is available, reducing the house edge on tough hands.
- –The hole card gives you certainty -- if the dealer does not have blackjack, play normally.
Optimal Play Advice
- *Take advantage of late surrender on 15 and 16 vs strong dealer upcards.
- *The peek rule means you can freely double and split without risking a dealer natural.
- *Insurance is still a bad bet even with the peek rule.
European Blackjack
0.39% edge
European Blackjack
0.39% edgeBasic Strategy Tips
- 1.Do not double or split aggressively against dealer 10 or Ace.
- 2.Double only on hard 9, 10, or 11.

- 4.Be cautious splitting against strong dealer upcards.
- 5.Hit soft 17. Stand on soft 19+.

- –No resplit allowed, making pair strategy more conservative.
- –With 2 decks, card composition matters more.
Optimal Play Advice
- *Play more conservatively when the dealer shows 10 or Ace because of ENHC.

Single Deck Blackjack
0.15% edge

Optimal Play Advice

Optimal Play Advice
- *Bankroll management is critical -- 5 hands at once means 5x the risk per round.

Rule Variants
Spanish 21
0.40% edge
Spanish 21
0.40% edgeBasic Strategy Tips

Pontoon
0.38% edge
Pontoon
0.38% edgeBasic Strategy Tips
- 1.Always twist (hit) on 14 or below -- it is mandatory.
