UK casinos offer 13 popular types of blackjack, from American, European, Vegas Strip and Atlantic City tables to Spanish 21, Pontoon and Blackjack Switch. Each version can change the odds, the pace and the decisions you face on every hand. Some types of blackjack give the dealer a small extra advantage, others hand you more freedom to split, double or even swap cards, and a few bolt a jackpot or a side bet onto the usual contest. Before you choose a table at a UK casino, it pays to know how these blackjack variations differ. Below we walk through each version, gather the published return figures in one place and point out which variants suit newcomers, which reward experience and which are best left alone.
How many types of blackjack should you know?
Thirteen versions cover almost everything you will meet at UK casino sites, from the classic American game to Pontoon and Spanish 21. Every one of them keeps the same core aim: beat the dealer by finishing on 21, or as close to it as you can, without going bust. What changes is the small print – how many decks sit in the shoe, whether the dealer may peek at the hole card, which hands you can split or double, how ties are settled and whether a side bet or jackpot is attached.
Those details matter more than they first appear. A single rule tweak can move the house edge up or down, alter which decisions make sense and turn a relaxed game into a demanding one. The quick-reference table below sums up the headline rule of each variant before we look at them one by one.
| Variant | Decks used | Headline rule | Best suited to |
|---|---|---|---|
| American (Classic) Blackjack | 6–8 | Dealer peeks at the hole card when showing an Ace | Beginners |
| European Blackjack | — | Dealer checks the second card only after players finish | Beginners |
| Vegas Strip Blackjack | — | Dealer stands on soft 17; split up to four hands | Players who want more options |
| Atlantic City Blackjack | — | Aces split once; late surrender allowed | Value seekers |
| Double Exposure Blackjack | — | Both dealer cards dealt face up | Players who like full information |
| Single Deck Blackjack | 1 | One 52-card deck | Experienced players |
| Spanish 21 | 6–8 | All 10 cards removed from the pack | Experienced players |
| Pontoon | — | Five Card Trick ranks just below Pontoon | Experienced players |
| Super Fun 21 | — | Six-card 20 wins outright | New and experienced players |
| Multi-Hand Blackjack | — | Up to 5 hands at once | Fast-paced play |
| Blackjack Switch | 6–8 | Swap cards between two hands | Value seekers |
| Perfect Pairs Blackjack | — | Side bet on a pair in the first two cards | Side-bet fans |
| Progressive Blackjack | — | Linked to a progressive jackpot | Jackpot hunters |
Classic versions: American, European, Vegas Strip and Atlantic City
American, European, Vegas Strip and Atlantic City Blackjack are the four foundation games that most other variants are built from. Once you understand how each one treats the hole card, splitting and doubling, the rest of the list becomes much easier to follow, and our blackjack rules page covers the basics if you need a refresher.
American (Classic) Blackjack
American Blackjack, often simply called Classic Blackjack, is the version you are most likely to find at both land-based and online casinos. It is usually dealt from a shoe of six to eight decks, although each casino sets the exact number. On every hand you choose between four core moves – Stand, Hit, Split and Double Down – and the outcome depends on those choices as much as on the cards you and the dealer receive.
The rule that tilts this version slightly towards the house is the dealer’s peek. When the dealer’s exposed card is an Ace, they may check the face-down hole card straight away, and if it completes a blackjack the hand is settled at once. Even with that edge for the dealer, the American game is regarded as one of the simplest and most enjoyable ways to learn how blackjack works, which is why it remains the default table at so many casinos.
European Blackjack
European Blackjack is the closest relative of the American game, but two differences change the way you play. First, the dealer is not allowed to look at the second card until every player has completed their hand. Second, doubling and splitting are far more restricted: you can normally only Double Down on totals of 9, 10 or 11, and splitting is limited to pairs worth 10.
It is the second most played variant at UK online casinos, so you will rarely struggle to find a table. Keep in mind that operators publish their own house rules, which means a European table at one site may not match the version offered by another. Spending a minute on the rules panel before your first bet is the easiest way to avoid surprises.
Vegas Strip Blackjack
Vegas Strip Blackjack takes its name from the Las Vegas Strip, where it became especially popular. The goal of reaching 21 without going bust is unchanged, but several rules move in the player’s favour compared with the American and European games. The dealer usually stands on soft 17 and is allowed to check for blackjack. You, meanwhile, gain flexibility: you can split up to a total of four hands and you can Double Down on any hand after a split. That extra room to manoeuvre is what draws many regular players to this version once they have outgrown the basic game.
Atlantic City Blackjack
Atlantic City Blackjack is named after the resort where it is mostly played, and a large share of American-style games actually follow its rules. Aces can be split only once, and only when a single card has been dealt. In return, you may split two different cards that are both worth 10, such as a King and a Queen, which European tables do not allow.
The standout feature is late surrender. If your hand looks hopeless, you can give it up and recover part of the money you staked earlier in the round. Microgaming’s version of Atlantic City Blackjack returns 99.65% to players, and it appears at many UK casinos that carry games from the provider.
Variants that change the deal or the payouts
Double Exposure, Single Deck, Spanish 21, Pontoon and Super Fun 21 keep the familiar table layout but alter the cards in play or the way hands are ranked. These tweaks have a direct effect on the house edge, so they are worth understanding before you stake real money.
Double Exposure Blackjack
Double Exposure Blackjack deals both of the dealer’s opening cards face up, so you always know exactly what you are playing against. That transparency comes at a price. The dealer wins every tie except when the result is a natural blackjack, and the house edge is higher than in Classic Blackjack. NetEnt and Microgaming each produce their own adapted version, so you are likely to see it at a UK casino that stocks titles from either of these game providers. It is an interesting game to try for its novelty, but the tie rule means it should not be your everyday choice if value matters to you.
Single Deck Blackjack
Single Deck Blackjack is played with just one standard pack of 52 cards. With so few cards in play, the variant is associated with a low house edge and a better chance of beating the dealer, which is why it appeals to players looking for value. Those benefits are greatest for experienced players who already make sound decisions on every hand. Most UK casino sites offer at least one single deck table, so it is not hard to track down, and it makes a natural next step once the classic six-to-eight-deck game feels comfortable.
Spanish 21
Spanish 21 is usually dealt from six or eight decks with every 10 card taken out of the pack. Removing those cards makes a natural blackjack harder to land, and that is the trade-off for a generous set of player options. You can, for example, Double Down on your first two cards whatever their value or suit. Many players find that the extra choices make Spanish 21 one of the more entertaining versions on offer, and its published return to player of 99.58% keeps it among the better-paying variants.
Pontoon
Pontoon has more in common with Spanish 21 than with the classic game, and a table usually seats between two and eight players. Each player is dealt two cards face down and must place a bet; hands are looked at once a further card has been dealt. What really sets Pontoon apart is its ranking of hands:
- Pontoon – an Ace together with a ten-value card, the strongest hand in the game.
- Five Card Trick – five cards totalling 21 or less, the second-best hand.
- Other hands – ranked by their total, with higher values beating lower ones.
Both a Pontoon and a Five Card Trick beat any hand made up of three cards. With a return to player of 99.60%, Pontoon also sits among the best-paying versions covered in this guide.
Super Fun 21
Super Fun 21 grew out of American Blackjack and keeps most of its structure, but adds rules designed to make the game livelier. The best known is the six-card bonus: if your hand totals 20 using six or more cards, you win regardless of what the dealer holds. The catch is the house edge, quoted at 0.94%, which is high by blackjack standards. Seasoned players therefore tend to look elsewhere, although the variant remains a fun change of pace for newcomers and veterans alike.
Variants built on extra hands, side bets and jackpots
Multi-Hand Blackjack, Blackjack Switch, Perfect Pairs and Progressive Blackjack each add something on top of the standard game. That extra layer can bring more excitement, but it also changes how your money is spread across a round.
Multi-Hand Blackjack
Multi-Hand Blackjack does exactly what its name suggests and lets you play up to five hands at the same time. Running several positions at once speeds up the action and gives you more opportunities to beat the dealer in each round. Remember, though, that every extra hand needs its own stake, so your total outlay per round rises with every seat you add. Setting a budget per round, rather than per hand, keeps this format under control.
Blackjack Switch
Blackjack Switch is dealt from six or eight decks, with the cards facing up. You place two bets of equal size and play two hands, and the twist is that you may trade cards between them – a move that would be considered cheating at any other table. Being able to rebuild two weak hands into stronger ones gives you a better shot at reaching 21, even though the game otherwise plays much like the classic version. Of the variants with published figures in this guide, Blackjack Switch offers the highest return to player at 99.92%, which also gives it the lowest house edge.
Perfect Pairs Blackjack
Perfect Pairs Blackjack adds an optional side bet that pays out when your first two cards form a pair, so the size of your win depends on those two cards and on how much you placed on the side bet. Payouts come in three tiers:
- Mixed Pair – two cards of the same rank in different colours.
- Coloured Pair – two cards of the same rank and colour but different suits.
- Perfect Pair – two identical cards of the same rank and suit.
Your main hand still plays out under the normal rules, so the side bet simply adds a second way to win from the opening deal. It is a well-regarded variant, but side bets usually carry their own odds, so treat them as an extra rather than the main event.
Progressive Blackjack
Progressive Blackjack will feel familiar if you enjoy progressive jackpot slots. The base game follows Classic Blackjack, but the table is linked to a progressive jackpot that grows from a percentage of the bets placed by players. For now, it is only available online. The appeal is simple: an ordinary session of blackjack with the outside chance of a large win at the end of it.
How should you choose between blackjack variations?
The right blackjack variation is the one you enjoy, with rules and a house edge that match your experience. Personal taste comes first, because you will play better at a table you are happy to stay at. After that, weigh up a few practical points.
- Rules and odds. Look at how the rules, bet limits and payouts work in your favour, and check the house edge wherever it is published.
- Complexity. Some versions are easy to follow, while others pile on special hands and exceptions that take time to learn.
- Where you play. Online tables often use rules that are kinder to players than those in land-based casinos, which is one reason many people prefer to play on the internet.
- Your experience. Newcomers benefit from a simple ruleset, while confident players can take on versions with more decisions.
In short, ask yourself which game gives you the most for your stake and which is the least complicated to learn. If you want to sharpen your decision-making before you commit, our beginner’s guide explains the basics, and the casino glossary decodes terms such as soft 17, hole card and late surrender.
Which blackjack variants have the lowest house edge?
Blackjack Switch has the lowest house edge of the variants we compared, returning 99.92% to players, ahead of Atlantic City Blackjack, Pontoon and Spanish 21. Finding a game with a small house edge is one of the simplest ways to make your bankroll last longer, yet the figure is rarely displayed prominently, so we have collected the published numbers in one place.
| Variant | Return to player (%) | What drives it |
|---|---|---|
| Blackjack Switch | 99.92 | Two hands with card swapping |
| Atlantic City Blackjack | 99.65 | Late surrender (Microgaming version) |
| Pontoon | 99.60 | Five Card Trick hand ranking |
| Spanish 21 | 99.58 | Flexible doubling despite the missing 10 cards |
Return to player is a long-term average calculated over a very large number of hands, so short sessions can swing well above or below it. At the other end of the scale, Super Fun 21 carries a house edge of 0.94%, and Double Exposure Blackjack sits above the classic game because the dealer wins most ties. If paying back the largest share of your stakes is your priority, start with the four variants in the table and compare them with our list of best payout casinos.
Best types of blackjack for beginners
American (Classic) Blackjack is the best starting point for beginners, followed by European Blackjack once the basics feel natural. Learning the original game first gives you a solid grasp of how hitting, standing, splitting and doubling work, and of how the dealer plays out a hand. Being new to blackjack does not have to be confusing; with the right version it is far more likely to feel fun and rewarding.
When you feel confident enough, European Blackjack is the logical next step. It shares most of its structure with the American game, so the switch is painless, and its differences – the delayed dealer check and the tighter doubling and splitting options – teach you to read a rules panel carefully. Playing both versions is a good way to build confidence before you try anything more unusual.
Which types of blackjack suit experienced players?
Experienced players can enjoy almost any variant, with Pontoon, Spanish 21 and Single Deck Blackjack offering the most room for skilled decisions. Once you know the classic game inside out, the options open up considerably, from the Five Card Trick in Pontoon to doubling on any two cards in Spanish 21. Blackjack Switch and Atlantic City Blackjack are also worth a look thanks to their strong return figures. Even at this level, treat any variant with out-of-the-ordinary rules with caution until you know exactly how it works.
Which blackjack variations should you avoid?
Avoid variants with rules that feel overly complicated, especially while you are still learning the game. Sticking to familiar versions makes costly mistakes and disappointment less likely. Be wary, too, of any table that seems to offer something too good to be true: in blackjack, as elsewhere, it usually is. Double Exposure and Super Fun 21 illustrate the point well – both are entertaining, but their attractive features are paid for with a higher house edge.
If anything about a game’s rules is unclear, contact the casino’s customer support team before you play. A reputable operator will happily explain its house rules, and our guide to choosing a casino shows what else to check before you register.
Key takeaways on blackjack variants
The best blackjack variant balances a low house edge with rules you fully understand. Start with American or European Blackjack, move on to Atlantic City, Vegas Strip or Single Deck Blackjack when you are ready, and save Pontoon, Spanish 21 and Blackjack Switch for when you can make the most of their extra options. Treat side bets, jackpots and multi-hand play as extras rather than the core of your session.

Frequently asked questions
What are the main types of blackjack?
The main types of blackjack are American (Classic), European, Vegas Strip and Atlantic City Blackjack, which form the base of most other versions. Popular spin-offs include Single Deck Blackjack, Spanish 21, Pontoon, Super Fun 21, Double Exposure, Multi-Hand, Blackjack Switch, Perfect Pairs and Progressive Blackjack. Each keeps the goal of reaching 21 without going bust but changes details such as the number of decks, the dealer’s rules or the payouts.
Which blackjack variations have the best return to player?
Blackjack Switch has the best return among the blackjack variations compared here, at 99.92%. Atlantic City Blackjack follows at 99.65% in Microgaming’s version, then Pontoon at 99.60% and Spanish 21 at 99.58%. These figures are long-term averages rather than guarantees, so results over a short session can differ, and it is worth checking the house rules at your chosen table before you play.
What is the difference between American and European Blackjack?
The biggest difference between American and European Blackjack is the dealer’s hole card. In the American game the dealer checks the face-down card when showing an Ace, while in the European game the dealer waits until every player has finished. European tables also usually restrict doubling to totals of 9, 10 or 11 and limit splits to pairs worth 10.
Is Single Deck Blackjack a good choice for experienced players?
Yes, Single Deck Blackjack suits experienced players well because it uses one 52-card deck and is linked to a low house edge, which improves the chance of beating the dealer. The benefit is greatest for players who already make sound decisions on every hand. Beginners may prefer to master American or European Blackjack first and move to single deck tables once the basics feel natural.
Is Pontoon the same as blackjack?
No, Pontoon shares the aim of reaching 21 but is closer to Spanish 21 than to the classic game. Its best hand, called a Pontoon, is an Ace with a ten-value card, and the Five Card Trick, made of five cards totalling 21 or less, ranks second. Both beat any three-card hand, and a return to player of 99.60% places Pontoon among the better-paying versions.
Which type of blackjack is best for beginners?
American (Classic) Blackjack is the best type for beginners because it teaches hitting, standing, splitting and doubling down in their simplest form. Once you feel confident, European Blackjack is an easy next step, as it shares most of the same structure. Leave complex versions with special hands, side bets or unusual payouts until you understand the basics thoroughly.
Does Spanish 21 use a full deck of cards?
No, Spanish 21 removes every 10 card from the pack, which makes a natural blackjack harder to land. To balance this, it is typically dealt from six or eight decks and gives players extra options, such as doubling down on any first two cards regardless of their value or suit. Its return to player of 99.58% keeps it among the better-paying blackjack variants.
