How to play blackjack

How to play blackjack: the aim in plain terms

Blackjack is a duel between each player and the dealer. Every seat at the table plays its own hand against the dealer’s hand, so the person next to you is not your opponent and their choices do not change your result on average. You win when your final total beats the dealer’s, or when the dealer goes over 21 and you have not. You lose when you go over 21 (a bust) or finish lower than the dealer. Equal totals are a push, and your stake comes back.

The game sits at the low-cost end of the casino because your decisions matter. Under good rules and correct play, the blackjack house edge is well under 1%, which is far below most slots and roulette bets. That edge still means the casino keeps a slice of everything staked over time, so treat each session as paid entertainment rather than a way to earn.

If you are brand new to the game, start with the blackjack hub for an overview of variants and strategy, then come back here for the mechanics of a single round.

Card values and hand totals

Cards 2 to 9 count at face value. Tens, jacks, queens and kings are all worth 10. An ace counts as 1 or 11, whichever helps the hand more. Suits play no part in the main game. Our page on blackjack card values goes deeper into how totals are added up.

A hand holding an ace counted as 11 is a soft hand, because one more card cannot bust it: the ace simply drops to 1. A hand with no ace, or with an ace that has to count as 1, is a hard hand. Ace-6 is soft 17; add a 9 and it becomes hard 16. Knowing which is which drives most decisions, so see soft hands and hard hands for the detail.

How to play a blackjack round, step by step

Every round, live or digital, follows the same order. Online the buttons appear at each stage and a timer limits how long you can think.

1. Place your stake in the betting circle within the table limits. Side bets, if offered, go in their own spots now.
2. The dealer gives each player two cards face up and takes one card face up (the up card). In a hole-card game the dealer also takes a second card face down.
3. If the dealer shows an ace, you are offered insurance. Where the dealer peeks and finds blackjack, the round ends at once.
4. Starting from the dealer’s left, each player acts: hit, stand, double, split or surrender, as the table allows.
5. Once all players have finished, the dealer reveals or draws their second card and plays out the hand under fixed rules.
6. Bets are settled: wins paid, losses collected, pushes returned. A new round starts.

Your moves: hit, stand, double, split and surrender

After your first two cards you choose from up to five actions. Not every table offers all of them, and some restrict when you can use them.

Doubling is your best chance to get more money on the table when the odds favour you, such as 11 against a weak dealer card. Splitting turns one awkward hand into two better ones, and the classic examples are splitting aces and eights. For timing, see when to double down and when to split. Surrender is a damage-control option for the very worst starting hands.

How the dealer plays: no choices, fixed rules

The dealer has no decisions to make. They must draw on 16 or less and stand on 17 or more. The one rule that changes between tables is what happens on soft 17 (for example ace-6). At some tables the dealer stands on it; at others the dealer hits. Standing is the better rule for you, and our page on the dealer soft 17 rule shows its cost.

The order of play is what gives the casino its edge. You act first, so if you bust you lose there and then, even if the dealer busts a moment later. That single rule is why matching the dealer’s style (always drawing to 17) is a losing approach.

Hole card or no hole card

In the American-style game the dealer takes a face-down second card and checks it when showing an ace or a 10-value card. If it makes blackjack, the round ends and you only lose your original stake. Many European tables use the no hole card method instead: the dealer takes the second card after everyone has acted. Under the European rules that Wizard of Odds analyses for no-peek blackjack (opens in a new tab), a dealer blackjack then takes your doubled and split money too, which is why doubling or splitting against a dealer 10 or ace is rarely right there. The game’s help page tells you which method it uses.

What each result pays

Most results settle at even money. The exception is a natural blackjack, an ace plus a 10-value card as your first two cards. According to the rules summarised by Wizard of Odds’ blackjack basics guide (opens in a new tab), a winning blackjack usually pays 3 to 2, though some tables cut it to 6 to 5. The full breakdown is on our blackjack payouts page.

That £3 gap between 3 to 2 and 6 to 5 looks small, but blackjacks arrive about once every 21 hands, so it adds up quickly. Wizard of Odds’ rule-variation figures (opens in a new tab) put the cost of 6 to 5 at 1.39% of every stake. Our 3:2 against 6:5 comparison works through it in pounds.

A worked blackjack round with real numbers

Here is one round at a £10 table to show how the pieces fit together. You place £10. You receive 6 and 5, a hard 11. The dealer shows a 6.

• Hard 11 against a dealer 6 is a standard double, so you add another £10 (now £20 at risk) and receive one card: a 9. Your total is 20, and you cannot draw again.
• The dealer turns over a 10 for 16. They must hit on 16 and draw a 7, making 23. The dealer busts.
• You win even money on £20, so you collect £40: your £20 back plus £20 profit.

Now change one card. Suppose your double brought a 2 instead, for 13. You are stuck on 13 because a double gives exactly one card. If the dealer turns 16 into 19, you lose £20. Doubling raises both the reward and the exposure, which is why it belongs only in spots where the maths backs it, as set out in blackjack basic strategy.

Live dealer and online blackjack: what changes

The rules above apply to both formats. What changes is the pace and the shuffle. Digital RNG blackjack reshuffles every round, while live blackjack is dealt from a physical shoe streamed from a studio. Live tables move more slowly because a real dealer handles the cards, and seats can fill up, though formats like Infinite Blackjack give every player the same starting hand so there is no waiting for a seat.

Under the Gambling Commission’s speed-of-play rules for casino games (opens in a new tab), digital casino games other than slots must take at least 5 seconds per game cycle. That caps a digital table at roughly 720 hands an hour at the absolute limit, though nobody plays that fast. Pace matters because your cost rises with the number of hands you play: at a 0.62% edge (Wizard of Odds’ figure for six-deck European rules), £10 hands cost about 6.2p each on average, so 60 hands an hour cost about £3.72 an hour and 150 hands cost about £9.30. Our online against live blackjack page compares the two in more detail.

Common mistakes new players make

• Copying the dealer. Always drawing to 17 ignores the fact that you bust first. It costs far more than following a strategy chart.
• Taking insurance. It is a side bet with its own house edge, roughly 7.5% from an eight-deck shoe on standard maths.
• Never hitting 12. Hard 12 busts only on a 10-value card, 4 chances in 13, so standing on it against a strong dealer card is usually wrong.
• Ignoring the payout sign. A 6 to 5 table costs far more than most rule differences combined.
• Chasing losses with bigger bets. Raising stakes after a loss does not change the edge; it only speeds up the losses. See common blackjack mistakes for more.

Playing blackjack online in the UK

UK-licensed casinos must verify your age and identity before you deposit or play, including in free demo mode. Credit cards cannot be used to gamble in Great Britain. The £5 and £2 per-spin stake limits apply only to online slots, so blackjack tables keep their own limits, set by the game and the casino. Before your first deposit you will be prompted to set a deposit limit, and it is a sensible thing to do. Our safer gambling section explains time-outs, reality checks and self-exclusion.
