House Edge: 0.5% (with basic strategy)

How to Play Blackjack

  1. Learn basic strategy: Memorize the basic strategy chart for the number of decks in play. This tells you the mathematically optimal action (hit, stand, double, split) for every possible hand combination.
  2. Understand hard vs soft hands: A soft hand contains an Ace counted as 11. Soft hands are more flexible — you can hit without risk of busting. Always follow separate strategy rows for soft hands.
  3. Master splitting pairs: Always split Aces and 8s. Never split 10s or 5s. The goal is to maximize expected value, not play by gut instinct.
  4. Know when to double down: Double down on hard 11 against any dealer card except Ace in H17 games. Double on hard 10 when dealer shows 2–9. Double on hard 9 when dealer shows 3–6.
  5. Manage your bankroll: Set a session budget before sitting down. Use consistent bet sizing — typically 1–2% of your session bankroll per hand. Stop when you hit your loss limit or session goal.

House Edge Explained

The house edge in blackjack comes from the player acting first. If both you and the dealer bust, the house wins because you busted first. With perfect basic strategy, the house edge is only 0.5% - one of the lowest in the casino. However, most players don't play perfect strategy, giving the house a 2-3% edge. Factors affecting house edge: - Number of decks: Fewer decks = lower edge - Dealer hitting soft 17: Increases edge - Blackjack payout: 3:2 is standard, 6:5 increases edge significantly - Doubling restrictions: Limiting options increases edge

Frequently Asked Questions

What is basic blackjack strategy?

Basic strategy is a mathematically proven set of decisions that tells you the optimal play for every possible hand combination. Following it reduces the house edge to approximately 0.5%.

Should I ever take insurance in blackjack?

No. Insurance has a house edge of over 7% — much worse than the base game. Even if you have blackjack, declining insurance has better expected value than taking even money.

When should I split pairs?

Always split Aces and 8s. Never split 10s or 5s. Split 7s, 6s, 3s, and 2s when the dealer is weak (2–6). Splitting rules can vary slightly by deck count and rules.
