Blackjack Basics

Blackjack is one of the few casino games where skill significantly impacts results. With proper strategy, you can reduce the house edge to under 0.5%.

Basic Strategy Rules

When to Hit

  • Hard 8 or less: Always hit
  • Hard 12-16 vs dealer 7-A: Hit
  • Soft 17 or less: Hit (or double if allowed)

When to Stand

  • Hard 17+: Always stand
  • Hard 12-16 vs dealer 2-6: Stand
  • Soft 19-20: Stand

When to Double Down

  • Hard 11: Double against dealer 2-10
  • Hard 10: Double against dealer 2-9
  • Hard 9: Double against dealer 3-6
  • Soft 16-18: Double against dealer 4-6

When to Split

  • Always split Aces and 8s
  • Never split 10s and 5s
  • Split 2s, 3s, 6s, 7s vs dealer 2-7
  • Split 4s vs dealer 5-6 (if double after split allowed)
  • Split 9s vs dealer 2-9 (except 7)

Insurance and Side Bets

Avoid insurance bets. The math never works in your favor. Similarly, most side bets carry high house edges.
