Everything below describes the standard casino game as UK players meet it online, at live-dealer tables and in land-based casinos. Where those three differ, each section says so, and a worked example hand near the end puts all the rules together.
How to Play Blackjack in 60 Seconds
Blackjack is a card game played against the dealer, not against the other players at the table. You win by finishing with a higher total than the dealer without going over 21. Reaching exactly 21 is not the aim in itself; a 19 that beats the dealer’s 18 wins just as much as a 21.
Each round follows the same five steps:
- Bet: place your stake in the betting box before any cards are dealt.
- Deal: you get two cards face up and the dealer gets one card face up, called the up-card.
- Decide: hit, stand, double down, split or surrender, one hand at a time, starting from the dealer’s left.
- Dealer plays: the dealer completes their hand by fixed rules, with no choices to make.
- Settle: every hand still in play is compared with the dealer’s total and paid or collected.
If your total goes over 21 you are bust and lose your stake at once, even if the dealer busts later. That single rule is where the casino’s edge comes from: you always act first, so you can lose before the dealer has taken a card. An ace and any ten-value card as your first two cards is a blackjack, also called a natural, and it beats every other 21.
Blackjack Card Values
Suits play no part in the main game; only the number on each card counts. Blackjack card values are simple, and the ace is the only flexible card in the deck.
| Card | Value | Example |
|---|---|---|
| 2 to 9 | Face value | 7 and 5 make 12 |
| 10, jack, queen, king | 10 | King and 8 make 18 |
| Ace | 1 or 11 | Ace and 6 make 7 or 17 |
Soft and Hard Hands
A hand with an ace counted as 11 is a soft hand, because one more card cannot bust it: ace-six is a soft 17, and if you draw a 10 the ace simply drops to 1 and you hold a hard 17. A hard hand has no ace, or has one that can only count as 1, so a big card can bust it. The difference matters, because the dealer rules and the right decisions both treat soft and hard totals differently.
The Table, the Deal and the Decks
A land-based table seats up to seven players in a half-moon around the dealer. Cards come from a shoe holding six or eight shuffled decks, and a plastic cut card near the back tells the dealer when to reshuffle. Online RNG tables usually reshuffle the virtual shoe after every round, which is one reason counting cards does not work there.
Hole Card or No Hole Card
In UK land-based casinos the dealer usually takes only one card at the start and draws the second one after every player has acted. This is the European no hole card rule. If that second card gives the dealer a blackjack, you normally lose any doubles and splits as well as your first stake, unless the table pays “original bets only”.
American-style tables deal the dealer a second, face-down card straight away, called the hole card, and the dealer checks it for blackjack before anyone acts. Online and live tables vary, so check whether the dealer peeks before you double or split against an ace or a ten.
Bet Behind on Live Tables
Live tables with a full set of seats let extra players bet behind a seated player. Your stake rides on their hand and you have no say in their decisions, so a bet behind wins or loses exactly as their hand does. Some tables also let you copy the seated player’s doubles and splits, or keep your stake as it is.
Your Options: Hit, Stand, Double, Split and Surrender
After the deal, each player plays their hand in turn. These are the moves the rules allow; which one is right depends on your total and the dealer’s up-card, and our blackjack basic strategy chart gives the correct play for every hand.
Hit
Take another card. You can hit as many times as you like until you stand or bust. In a land-based casino, tap the table with a finger to ask for a card.
Stand
Keep your total and end your turn; in the UK this is also called sticking. At the table, wave your hand flat above your cards. Standing on a weak total such as 13 or 14 is correct when the dealer shows a small card, because the dealer then has to draw and may bust.
Double Down
Double your stake and take exactly one more card, then stand. Most online tables let you double on any first two cards, while some land-based tables restrict it to totals of 9, 10 or 11. Doubling on 11 against a dealer 6 is the textbook example, because one card is very likely to leave you on a strong total.
Split
If your first two cards have the same value, you can split them into two separate hands by adding a second stake of the same size. Each hand then gets a second card and is played on its own. Split aces receive only one card each, and an ace plus a ten after a split counts as 21, not blackjack, so it pays even money.
Many tables let you double after splitting; some also let you split again if you are dealt another matching card. Two ten-value cards count as a pair at many tables, but splitting a total of 20 is almost always a mistake. The blackjack strategy guide lists which pairs to split against each up-card.
Surrender
Give up your hand and take back half your stake. Late surrender, the usual form, is only allowed after the dealer has checked for blackjack; early surrender, which comes before that check, is rare. Not every table offers it, but where it exists it is the right call with 16 against a dealer 9, 10 or ace. See when to surrender for the full list.
Blackjack Insurance and Even Money
When the dealer’s up-card is an ace, you are offered insurance: a side bet of up to half your stake that pays 2:1 if the dealer has blackjack. It sounds like protection, but it is simply a bet that the dealer’s next card is a ten, and the house edge on insurance is about 5.9% in a six-deck game.
Even money is the same bet under another name. If you hold a blackjack and the dealer shows an ace, you can take a guaranteed 1:1 payout instead of risking a push. It gives exactly the same result as insuring your blackjack, so the basic strategy answer to both offers is the same: decline insurance and even money.
Blackjack Dealer Rules
The dealer never chooses. Once every player has finished, the dealer turns over or draws the second card and plays the hand by a rule printed on the table: hit on 16 or less, stand on 17 or more. If the dealer busts, every hand still in play wins.
S17 and H17: The Soft 17 Rule
Tables differ on one hand: soft 17, such as ace-six. At an S17 table the dealer stands on it; at an H17 table the dealer must hit it. The H17 rule adds about 0.22% to the house edge. UK land-based casinos and most live-dealer tables stand on all 17s, but online RNG games vary, so read the felt or the help panel before you play.
How Blackjack Hands Are Paid
Once the dealer’s hand is complete, each hand is settled against it. The table shows what a £10 stake returns in each case, and a push simply returns your stake.
| Result | Pays | On a £10 stake |
|---|---|---|
| Blackjack (natural) | 3:2 | £15 profit |
| Blackjack at a 6:5 table | 6:5 | £12 profit |
| Beat the dealer | 1:1 | £10 profit |
| Push (same total) | Stake returned | £0 |
| Surrender | Half the stake back | £5 loss |
| Bust or lower total | Stake lost | £10 loss |
| Insurance wins (£5 bet) | 2:1 | £10 profit on the £5 |
The one payout worth checking before you sit down is the blackjack itself. A 3:2 table pays £15 for a natural on a £10 stake, a 6:5 table only £12, and that shortfall adds about 1.39% to the house edge, more than every other rule change combined. If the table says 6:5, find another one.
Blackjack Rule Variations That Change the Odds
With basic strategy, the house edge at a standard eight-deck table where the dealer stands on soft 17 is a little under 0.5%. The rules printed on the felt move that figure up or down, and a plus sign below means the casino gains.
| Rule | House edge | What to look for |
|---|---|---|
| Blackjack pays 6:5 | +1.39% | “Blackjack pays 3 to 2” on the felt |
| Dealer hits soft 17 | +0.22% | “Dealer stands on all 17s” |
| No double after split | +0.14% | DAS listed in the help panel |
| Six decks instead of eight | −0.02% | Small gain, rarely worth a switch |
| Late surrender offered | −0.08% | A surrender button or line |
| Resplitting aces allowed | −0.08% | “Aces may be resplit” |
| Single deck | −0.48% | Check it still pays 3:2 |
Most of Evolution’s live-dealer blackjack tables use eight decks, stand on all 17s, pay 3:2 and allow doubling after a split, but they do not allow resplitting. That is a good rule set, and it is the one our strategy chart is built for.
Blackjack Side Bets
Many online and live tables add optional side bets next to the main betting box. They settle on your first two cards, or on those two cards plus the dealer’s up-card, before the hand is played, and their house edge is many times higher than the main game’s.
| Side bet | What wins | House edge |
|---|---|---|
| Perfect Pairs | A pair in your first two cards, 6:1 to 25:1 | 4.10% (8 decks), 6.11% (6 decks) |
| 21+3 | A poker hand with the up-card, 5:1 to 100:1 | 3.70% (8 decks) |
| Insurance | Dealer blackjack, pays 2:1 | About 5.9% (6 decks) |
Perfect Pairs pays 6:1 for a mixed pair, 12:1 for a coloured pair and 25:1 for a perfect pair of the same suit. 21+3 pays 5:1 for a flush, 10:1 for a straight, 30:1 for three of a kind, 40:1 for a straight flush and 100:1 for suited trips. Paytables differ between game providers, so the house edges above apply only to these paytables, taken from the Wizard of Odds side-bet analyses. The rule of thumb holds for all of them: a side bet costs more per pound than the hand it sits next to.
Hand Signals and Table Etiquette
In a land-based casino the dealer and the cameras rely on hand signals, so a spoken “hit” is usually confirmed with a gesture. Online and live tables replace all of this with buttons, and no hand signals are needed online.
- Hit: tap the table beside your cards.
- Stand: wave your hand flat, palm down, above your cards.
- Double down: place a second stake of the same size next to your first and say “double”.
- Split: place a matching stake next to your first and say “split”; the dealer separates the cards.
- Chips: leave your stake alone once the cards are out, and never touch cards dealt face up from a shoe.
Online, Live Dealer and Land-Based Blackjack
The rules of the hand are the same in all three places, but the way the game runs is not. RNG tables deal by software, let you take as long as you like and usually accept lower stakes than live tables. Live-dealer tables use a real shoe and a real dealer, give you a few seconds to decide on each hand and often let you bet behind when the seats are full.
Land-based tables add the no hole card rule, hand signals and higher minimum stakes, but also the full social game. Several variants change the rules themselves: pontoon is the British cousin with its own names for the moves, and multihand blackjack lets you play several hands at the same time. 21 Duel Blackjack and Double Attack Blackjack each rework the standard rules in their own way.
A Worked Example Hand
Here is one round at a £10 table that stands on all 17s and allows doubling after a split. It shows how several of the blackjack rules above work together, and how a split can triple your stake on a single round.
- The deal: you are dealt 8 and 8, a total of 16, and the dealer shows a 6.
- Split: you add a second £10 and split the eights into two hands of 8.
- First hand: you draw a 3 for 11 and double down, adding another £10. Your one card is a 9, so this hand stands on 20.
- Second hand: you draw a 10 for 18 and stand.
- Dealer: the second card is a 10, giving 16. The dealer must hit, draws an 8 and busts on 24.
- Settlement: both hands win. The doubled first hand pays £20 and the second hand pays £10, so you finish £30 up on £30 staked.
Had the dealer drawn a 5 instead of the 8, their 21 would have beaten both hands and cost you all £30. Splitting eights is still correct, because two hands starting from 8 lose less over time than one hand of 16.
Not the Casino Game? British 7-Card Blackjack
In the UK, “blackjack” is also the name of a pub and family card game that has nothing to do with the casino table. Each player gets seven cards and tries to be the first to get rid of them all by matching the suit or number of the card on top of the pile. Twos, black jacks and eights are the power cards: they make the next player pick up two or five cards, or miss a turn, and an ace changes the suit.
House rules for that game vary from table to table, and it is closer to Switch or Crazy Eights than to 21. Every other section of this guide covers the casino game.
Blackjack Rules: Quick Reference
The whole game on one screen, for the rule set you will meet most often at UK online and live tables.
| Rule | Standard | Check for |
|---|---|---|
| Aim | Beat the dealer without going over 21 | Bust first, lose first |
| Decks | Six or eight | Single deck paying 6:5 |
| Dealer | Hits 16, stands on all 17s | Hits soft 17 (H17) |
| Blackjack | Pays 3:2 | Pays 6:5 |
| Double | Any two cards, and after a split | 9, 10 or 11 only |
| Split | Once, aces get one card each | Resplitting allowed |
| Insurance | Pays 2:1 against a dealer ace | Always decline it |

Blackjack Rules: The Short Version
Blackjack rules fit on a single card: beat the dealer without going over 21, count aces as 1 or 11, and remember that the dealer must hit 16 and stand on 17. Before you play, check that blackjack pays 3:2 and how the table treats soft 17, and decline insurance whenever it is offered. Rules and figures last checked September 2026.
Blackjack Rules FAQ
The questions players ask most often about the rules of blackjack, answered in a line or two each.
1️⃣ What are the basic rules of blackjack?
You try to beat the dealer’s total without going over 21. Cards 2 to 10 count at face value, jacks, queens and kings count as 10 and an ace counts as 1 or 11. The dealer must hit 16 or less and stand on 17, and a blackjack pays 3:2.
2️⃣ How do you play 21 with friends at home?
Use the same rules, with one player acting as the dealer and playing their hand by the fixed rule: hit 16 or less, stand on 17. One or two decks are enough, agree the blackjack payout before you start and pass the deal round the table.
3️⃣ Does the dealer hit on soft 17 in UK casinos?
No, UK land-based casinos and most live-dealer tables stand on all 17s, including soft 17. Online RNG games vary, so check the help panel before you play; hitting soft 17 adds about 0.22% to the house edge.
4️⃣ What happens if you tie with the dealer?
A tie is a push and your stake is returned. A blackjack beats any other 21, so your natural still wins if the dealer reaches 21 with three or more cards.
5️⃣ How many decks are used in blackjack?
Most online and live tables use six or eight decks, and live-dealer tables usually use eight. Single-deck and double-deck games exist, but check they still pay 3:2.
6️⃣ Does blackjack pay 3:2 or 6:5?
The standard payout is 3:2, so a natural returns £15 profit on a £10 stake. Some tables pay only 6:5, or £12, which adds about 1.39% to the house edge.
7️⃣ What is insurance in blackjack and is it worth it?
Insurance is a side bet of up to half your stake, offered when the dealer shows an ace, and it pays 2:1 if the dealer has blackjack. It is not worth taking: the house edge is about 5.9% in a six-deck game.
8️⃣ Can you split aces in blackjack?
Yes. Each ace becomes a separate hand and receives only one more card, and an ace and a ten count as 21, not blackjack, so they pay even money. Only some tables let you split aces again.
9️⃣ When can you surrender in blackjack?
Only at tables that offer it, and only on your first two cards. With late surrender you give up after the dealer has checked for blackjack and get half your stake back.
🔟 Is 7-card blackjack the same game?
No. British 7-card blackjack is a pub and family game in which you try to get rid of all your cards, closer to Switch or Crazy Eights. It shares only the name with the casino game.
