  • Aces: Worth 1 or 11, whichever benefits your hand.

4. Player Decisions

  • Hit → Take another card.
  • Stand → Keep your current total.
  • Double Down → Double your bet, get one extra card only.

  • Surrender (if allowed) → Fold your hand and reclaim half your bet.

5. Dealer’s Turn

    • In most games, the dealer stands on soft 17 (Ace counted as 11).
    • Some versions require the dealer to hit soft 17 (check table rules).

6. Resolving Bets

  • Player busts → Lose automatically.
  • Dealer busts → Player wins.
  • If both stay under 21:
    • Higher hand wins.
