How to Play
Blackjack
Master the most popular casino card game. Learn basic strategy, understand when to hit, stand, double down, or split, and play with one of the lowest house edges in the casino.
📖Game Overview
Blackjack (also known as 21) is a card game where players compete against the dealer, not against each other. The objective is simple: get a hand value closer to 21 than the dealer without exceeding 21 (busting). Unlike most casino games, blackjack involves player decisions that significantly affect the outcome, making it one of the few games where skill matters.
With optimal play using basic strategy, blackjack offers one of the lowest house edges in the casino— often below 1%. This makes it attractive for players who want to maximize their chances while enjoying an engaging game.

Frequently Asked Questions
Frequently Asked Questions
What is blackjack and how do you win?
Blackjack (also called 21) is a card game where you compete against the dealer. The goal is to get a hand value closer to 21 than the dealer without going over (busting). Number cards count as their face value, face cards count as 10, and Aces count as 1 or 11. If you get 21 with your first two cards (Ace + 10-value card), that's a blackjack and typically pays 3:2.
What is basic strategy in blackjack?
Basic strategy is a mathematically optimal way to play every hand based on your cards and the dealer's upcard. It tells you when to hit, stand, double down, or split. Following basic strategy reduces the house edge to as low as 0.5% in favorable games. Basic strategy charts are available and legal to use in casinos.
When should I hit or stand in blackjack?
Generally: Always hit on 11 or less. Stand on hard 17 or higher. Hit on soft 17 (Ace-6) or less. Stand on soft 18 or higher against dealer 2-8. The exact decision depends on the dealer's upcard—basic strategy charts provide precise guidance for every situation.
When should I double down?
Double down when you have an advantage: always on 11 (except against dealer Ace in some games), on 10 against dealer 2-9, on 9 against dealer 3-6, and on soft hands like A-2 through A-7 against dealer 4-6. Doubling lets you double your bet in exchange for receiving exactly one more card.
When should I split pairs?
Always split Aces and 8s. Never split 10s or 5s. Split 2s, 3s, 6s, 7s, and 9s in specific situations based on the dealer's upcard. Splitting Aces is particularly valuable because you get two chances at blackjack. When you split, you place an additional bet equal to your original bet.
What does it mean to 'bust' in blackjack?
Busting means your hand value exceeds 21, and you automatically lose regardless of the dealer's hand. This is why you should be cautious when hitting on hands of 12 or higher—the risk of busting increases. The dealer must also follow rules and can bust, which means all remaining players win.
Should I take insurance in blackjack?
No, insurance is generally a bad bet. When the dealer shows an Ace, you can bet up to half your original wager that the dealer has blackjack. This pays 2:1 but has a house edge of about 7%. Even card counters only take insurance in specific high-count situations. It's better to decline insurance.
What is the house edge in blackjack?
With optimal basic strategy, the house edge ranges from 0.5% to 2% depending on the rules. Favorable rules (dealer stands on soft 17, double after split allowed, late surrender) lower the edge. Unfavorable rules (6:5 blackjack payout, dealer hits soft 17, no double after split) increase it. Rule variations significantly impact your odds.
What does 'dealer stands on soft 17' mean?
A soft 17 is a hand containing an Ace counted as 11 (e.g., Ace-6). Some games require the dealer to stand on soft 17 (S17), while others require hitting (H17). S17 is better for players, reducing the house edge by about 0.2%. Always prefer S17 games when available.
Can I count cards in blackjack?
Card counting is a legal technique where you track the ratio of high to low cards remaining in the deck. When the count is favorable (more high cards), you bet more. It requires significant practice and only provides a small edge (1-2%). Casinos can ask you to leave if they suspect counting. Online RNG blackjack shuffles after each hand, making counting impossible.
What is surrender in blackjack?
Surrender lets you forfeit your hand and lose half your bet before playing. Late surrender (after dealer checks for blackjack) is offered in some games. Early surrender (before dealer checks) is rare but very favorable. Surrender is correct in specific situations, like hard 16 against dealer 9, 10, or Ace.
Should I play single-deck or multi-deck blackjack?
Single-deck blackjack offers the lowest house edge (around 0.5% with good rules) because it's easier to track cards and blackjacks occur more frequently. However, casinos often compensate with worse rules (6:5 blackjack payout). Multi-deck games (6 or 8 decks) typically have better rules overall. Compare the complete rule set, not just deck count.
What is the difference between hard and soft hands?
A soft hand contains an Ace counted as 11 without busting (e.g., Ace-6 = soft 17). A hard hand either has no Ace or the Ace must count as 1 (e.g., 10-7 = hard 17, or Ace-6-10 = hard 17). Soft hands are more flexible because you can't bust by hitting—the Ace can switch from 11 to 1.
What are blackjack side bets?
Side bets are optional wagers on outcomes like Perfect Pairs (your first two cards are a pair), 21+3 (poker hand from your cards and dealer's upcard), or Lucky Ladies (hand totaling 20). These typically have high house edges (3-25%) and should be avoided if you want to minimize losses. They're entertainment bets, not strategic plays.
Is online blackjack fair?
Licensed online casinos use certified Random Number Generators (RNG) tested by independent agencies (eCOGRA, iTech Labs). Live dealer blackjack uses real cards and dealers via video stream. Both are fair if you play at regulated casinos. Avoid unlicensed sites. Check for licensing from UK Gambling Commission, Malta Gaming Authority, or similar reputable regulators.
