How to Choose Your Blackjack Casino 

Our carefully select list features the best blackjack sites on the market, but you’ll still need to pick out the casino that’s best suited to you. Keep the following factors in mind when comparing sites and you’re sure to find enjoy a first-class blackjack experience.

Licensing

First things first, you should check that the blackjack site holds a UK Gambling Commission (UKGC) licence.

This means that your account and personal details are kept private, and that the blackjack games you play are tested and audited to ensure fairness. We only recommended licensed blackjack casinos on our lists, but be sure to check for the UKGC logo on the casino’s website if you’re comparing sites for yourself.

Games Selection

While all the top online casinos on our list feature a variety of blackjack titles, the variations on offer aren’t always the same. Browsing the games library and live casino section will help you get a feel for whether a blackjack site is right for you.

You can also use our expert reviews to easily find out which software is used by each of our recommended UK casinos.

Bonuses

All our top online blackjack sites offer attractive welcome deals, so you can easily compare the best bonuses on the market and find the right one for you.

Remember that bigger isn’t necessarily better when it comes to casino bonuses- terms and conditions, such as wagering requirements, might mean that you’re better off opting for a more modest offer.

Banking Options

Most UK casinos offer a range of deposit and withdrawal methods, but certain banking options like PayPal and pay by phone bill aren’t available at every site.

While you’re at it, read up on the withdrawal limits and processing times to ensure you pick a site that offers easy access to your winnings if you do strike lucky with real money blackjack.

Customer Service

There may come a time when you need to get in touch with your chosen casino, in which case it’s helpful to have a comprehensive customer service offering.

Some of the best blackjack sites offer 24/7 support via telephone phone, email and live chat, but these options aren’t available at every site. It’s important to check that the customer support options suit you, just in case you were to have a problem or query.

Blackjack Basics

Blackjack is perhaps the most popular card game at online casinos. The concept of blackjack is fairly simple: hit  21 without going bust. However, whereas other casino games like roulette and slots are determined entirely by luck, there’s a skill element to blackjack.

This means that experience and knowledge can actually help you make wiser decisions, so you know when it’s worth taking a risk or sticking with the hand you have. However, if you’re a beginner and want the lowdown on the basics, we’ve got you covered:

  • The aim of the game is to get your hand as close to 21 as possible. If you go above 21, then you ‘bust’ and lose the round.
  • The value of cards 2 to 10 corresponds to their numerical order. Jacks, Queens and Kings are worth 10, and Aces are worth either 1 or 11, depending on your choice.
  • Each round starts with the dealer dealing two cards, both to yourself and the house. Whereas both your cards are both face up, the dealer has one face up— the ‘hole’ card— and the other face down.
  • You can choose to either hit or stand. Hit means you draw another card, while stand keeps your hand it is. You can hit as many times as you want before going bust.
  • If your initial two cards are the same value, you can choose to split, which means you separate the cards into two hands and play the rest of the round with both. The other option is to double down, where you double your bet in exchange for another card being dealt. Beware that you can’t hit again after receiving the third card, so it’s all or nothing.
  • There are three ways to win at blackjack: hitting a ‘natural’ 21 on the first two cards, having a higher hand value than the dealer at the end of the round, or the dealer going bust. If both hands end on 21, the game will usually result in a ‘push’ and your stake will be returned.

Blackjack House Edge

Online blackjack has one of the lowest house edges of all casino games- around 0.5% to 1% for most variations when you play with basic strategy. In fact, if you play with the optimal blackjack strategy, you can reduce the house edge even further.

But it’s not all just about knowing when to hit and stand. Splitting, doubling down and wagering on side bets can affect blackjack odds and payouts, as can the number of decks used and any other rules that are specific to the variation you’re playing.

Types of Blackjack Games

The game of blackjack has travelled from the sultry Spanish heat of Miguel de Cervantes’ novels at the end of the 16th century, through the rest of Europe, and eventually across the Atlantic to North America on the ships of European settlers.

These migrations have in turn produced countless blackjack variants, each with their own unique quirks that affect how punters should play the game.

Below are some of the most popular types of blackjack, all of which are available to play at the best blackjack casinos.

American Blackjack

In American blackjack, player and dealer are dealt two cards each. Both of the player’s cards are dealt face up (upcards), while the dealer is dealt one upcard and one card face down (downcard), which is known as the hole card. If the dealer’s upcard is an ace, and the possibility of hitting a blackjack is open, the dealer is permitted to peek at the hole card.

If the dealer does indeed have a blackjack, the hand is over and the dealer collects all the bets on the table.

What is vital is that players are aware how many decks are in play in their chosen variant. In American blackjack, casinos may choose between six and eight decks, so make sure you know how many are in circulation. The number of decks in blackjack influences the casino’s house edge; the more there are, the greater the casino’s advantage.

American blackjack players are allowed to double down on any hand, and are also allowed to double down following a split. Players are able to split their hands three times for a total of four hands – aces can only be split once, but any ten-value card can be split.

American blackjack allows the surrender betting option, where players are able to forfeit their hand after their first two cards are dealt in exchange for 50% of their original stake.

  • 6-8 decks in play
  • Dealer receives a hole card
  • Double down on any hand
  • Hands can be split three times
  • Players are able to surrender

European Blackjack

The rules of European blackjack are considered more stringent than its American cousin, with less flexibility in the betting options afforded to players at the table. This is compensated by the fact that there are only two decks in play in European blackjack games, reducing the house’s edge over players at the table.

The dealer is initially only dealt one upcard at the start of the hand, meaning there is no hole card in European blackjack and no opportunity for the dealer to peek. Instead, the dealer receives their second card after everyone else’s hand has played out.

European players are only allowed to double down if their hand has a combined total of nine, ten, or eleven, and aren’t permitted to double down once they’ve made a split call. Players can only split their hand once, and ten-value cards must be the same in order to call a split. There is also no surrender option in European blackjack.

  • Two decks in play
  • No hole card for the dealer
  • Dealer’s hand plays out after all other players
  • Double down only on nine, ten and eleven
  • Players are not able to surrender

Vegas Strip Blackjack

Vegas Strip blackjack is a modification of the American variant made specifically for the casinos of Sin City. There are four decks in play here, which slightly decreases the house edge from American games.

The American and European variants both ignore hard and soft 17s, but these are in play in Vegas Strip blackjack. Aces can be worth both one and 11 depending on the hand, and a soft 17 is a hand that includes an ace as an 11. A hard 17, by contrast, is a hand containing a one-valued ace. In Vegas Strip blackjack, the dealer is always required to stand on a soft 17.

One of the reasons why Vegas Strip is a popular option is because of the entertaining rule around insuring hands. If the dealer’s upcard is an ace, players are able to insure their hand against a blackjack being turned over on the dealer’s downcard – a successful insurance call will pay out at a rate of two to one.

Pairs can be split a maximum of three times and players are able to split unmatched ten-value cards. Players are also able to split aces, but achieving 21 from two cards on a split ace does not count as a blackjack. Unlike in the American variant, players aren’t permitted to surrender.

  • Four decks in play
  • Dealer stands on soft 17
  • Players can insure their bets in response to the dealer’s upcard ace
  • Players can split three times
  • Players cannot surrender

Blackjack Switch

Blackjack Switch was invented by card counter Geoff Hall in 2000. Hall had been left particularly frustrated during one stint at the table when, for the second hand in a row, he noticed that his split hands would’ve been significantly improved if he were able to switch the two top cards of both hands.

Here’s how it works: the starting position is essentially the same as a split hand in other variants, with two hands dealt instead of one. Wagers on both hands must be identical at the start of the betting, but these hands then play out independently. The first betting call is to decide whether you want to switch the top two cards – this option will only be offered once.

To mitigate against the adverse effect of receiving identical cards eligible for the switch, Blackjack Switch contains a unique side bet known as the super match. This side bet rewards pairs at a payout of one to one, three of a kind at five to one, two pairs at eight to one, and four of a kind at 40 to one.

There’s one more crucial rule to be aware of in Blackjack Switch. In 2003, Hall introduced a push on 22 rule. If the dealer’s hand amounts to 22, they are not bust, but instead tie their hand with any remaining players, excluding those who’ve produced a natural blackjack.

The particulars over how many decks are in play, soft and hard 17s, and split, double down and surrender betting options are down to the casino itself to resolve, so make sure you pay attention to these stipulations. Online Blackjack Switch games are developed solely by Playtech, so only the very best blackjack casino sites will offer this version of the game.

  • Games are played with four, six or eight decks
  • Players are dealt two hands as opposed to one
  • They are able to exchange their top two cards
  • Dealer is not bust on 22 thanks to the push rule
  • Players can take part in a cross-hand side bet called the super match

Blackjack Perfect Pairs

The concept of Blackjack Perfect Pairs started as a side bet rule in other blackjack games, but its popularity made it a variant in its own right. All of the specifics on rules will vary across operators and their games, including the number of decks in circulation.

The side bet that gives the game its name involves speculating on whether a player’s initial hand will contain one of three pairs:

  • A mixed pair, where the cards have the same value, but are different in suit and colour
  • A coloured pair, where the cards have the same value and colour, but a different suit
  • A perfect pair, where all elements are identical

Players wanting to participate in the side bet must do so before their cards have been dealt. The side bet is then settled before the main game, with most games offering payouts on perfect pairs at 30 to one.

After all the side bets have been settled, the game resumes according to whichever standard variant it follows. Before taking part in Perfect Pairs at a blackjack UK casino, make sure you’re aware of all the rules it adheres to.

  • Two, four, six or eight decks in play – the more there are, the harder it is to hit a pair;
  • Players take part in a side bet wagering on pairs;
  • All side bets must be made before the hand is dealt;
  • Players involved in the side bet are looking for one of three pairs;
  • Following the side bet, the game resumes according to its variant’s rules.

Blackjack Variations

Whether you want to play low limit games or bet big on high stakes blackjack, there are lots of exciting variations on offer at the best online blackjack sites. Each of these games has unique rules or features which set them apart from traditional blackjack, so make  sure you’re clued in before you wager real money. Here are the most popular blackjack variations you can play online:

  • Blackjack surrender – The surrender move gives you  the option to forfeit your hand after being dealt the first two cards, and only lose half your wager. This means you can cut your losses if your don’t like the look of your hand;
  • Blackjack switch – In this variation, you’re dealt two hands rather than one. Players then have the choice of switching the second cards dealt to create the strongest possible hands;
  • Double exposure blackjack – The major difference here is that both the dealer’s cards are dealt face up, making the player’s decision a bit easier. However, casinos make up for this by offering slightly lower payouts, and the dealer wins on ties unless you hit a natural blackjack.
  • Perfect Pairs Blackjack – Perfect Pairs is a side bet where you win if your first two cards are a pair. The payout depends on the strength of the pairing- a pair of the same rank and suit can land you the biggest win;
  • 21+3 Blackjack – 21 + 3 is another side bet which pays out if your first two cards and the dealer’s hole card form a flush, straight, three of a kind, straight flush or suited three of a kind.
  • Pontoon – In pontoon, both the dealer’s cards are dealt face down, making things slightly harder from the player’s perspective. On the plus side, a ‘pontoon’ or natural blackjack pays out 2:1, rather than 3:2 as in standard games;
  • Single deck blackjack – Most online blackjack games use six or eight decks, which increases the house edge, but this variation uses just one. The house edge can be as low as 0.10% in single deck blackjack games, but you won’t find it at every online casino;
  • Super fun 21 – This variation has several twists on the traditional rules, but the main difference is that a player’s hand consisting of six cards or more, and totalling 20 or less, beats the dealer- even if the dealer has 21;
  • Progressive blackjack – Progressive blackjack uses the traditional rules, but players can also take a shot at the progressive jackpot by placing a side bet. In most games, the side bet is a wager on you being dealt a specific combination of cards, such as four aces;
  • Multi-hand blackjack – As the name suggests, this variation maintains the gameplay of classic blackjack but lets you play several hands at once. You can play up to 5 hands at a time in some multi-hand blackjack games.

Live Dealer Blackjack

If you’re looking for a more authentic blackjack experience, live dealer blackjack might be right up your street. The top live blackjack sites stream their games in HD from purpose built studios, so you’ll experience all the authentic sights and sounds of a brick and mortar casino without stepping foot outside your house.

 

The live chat feature allows you to interact with the expert dealers and other players, just as you might in a real casino, making for more immersive blackjack gaming. Most of the best live blackjack sites also host a wide range of tables, including VIP tables with high staking limits and low limit options, so there are games to suit players of different budgets.

Best Blackjack Software Developers

A broad range of casino software providers have tried their hand at blackjack, but a few stand out from the rest.

NetEnt

NetEnt is well known for its innovation, and this can be seen in its blackjack titles. One of this developer’s latest releases is live dealer Perfect Blackjack, an industry first which deals cards according to perfect strategy.

You can enjoy this unique game, as well as other live blackjack tables, in the NetEnt Virtual Casino; a virtual casino floor that takes live dealer games to the next level. RNG blackjack fans won’t be short of choice either.

Double Exposure Blackjack and Pontoon are just two examples of the top blackjack games on offer at NetEnt casinos. Even better still, all of these games run perfectly on mobile devices, thanks to the NetEnt Touch platform.

Evolution Gaming

Fans of live dealer blackjack can’t go wrong with Evolution Gaming.  High rollers can take their pick from a wide range of VIP tables, including live dealer Salon Privé blackjack, which offers some of the highest bet limits of all online blackjack games.

Casual players can enjoy low limit Infinite Blackjack, which caters to an unlimited number of players, as well as the low stakes Blackjack Party, a party-themed variation that livens things up a bit.

The Bet Behind feature allows you to wager on other players’ hands while you wait for a seat at the table, while Pre-Decision means you can make your moves right at the start of each round, making for speedier gameplay.

Playtech

Playtech has produced some of the most unique RNG blackjack games on the market. One popular variation is Buster Blackjack, where you can win from a side bet if the dealer goes bust.

There’s also Lucky Lucky Blackjack, where you can place a side bet that wins on a variety of scenarios, such as the first three cards being sevens or totalling 21.

Perfect for those looking to up the ante. Playtech also has options for live dealer fans, with five blackjack tables to choose from, all of which are streamed from the developer’s state-of-the-art live casino in Latvia.

Microgaming

This software giant has developed one of the widest ranges of RNG blackjack variations. Titles include Atlantic City Blackjack, which has an average house edge of just 0.35%, as well as Vegas Strip Blackjack, where you can place an insurance bet if the dealer’s first card is an ace.

With variations to suit a range of different budgets, including multi-hand and live dealer blackjack games, Microgaming casino software is sure to please blackjack fans.

Blackjack Casino Bonuses

Plenty of top online casinos offer welcome bonuses that you can use for a free shot at 21.  Blackjack bonuses come in all different shapes at sizes, but here’s a look at the top offers you’ll find at online casinos:

Matched Deposit Blackjack Bonus

A matched deposit welcome bonus gives you a bonus fund worth a certain percentage of your deposit. The percentage match can range anywhere from 50% to 200%, but the most common offer is a 100% match, and there’s almost always a cap on the bonus.

For example, if a site offers a ‘100% match up to £200’, this means the casino will match your deposit up to £200. So if you deposit £200, you’ll receive £200 in casino bonus funds that you can use on your favourite blackjack tables.

No Deposit

As the name suggests, a no deposit bonus gives you a freebie simply for signing up. No deposit cash bonuses are smaller than matched deposits— usually a free £5 or £10 no deposit— but who can complain about free casino credit?

They might not be the most common of offers, but claiming a blackjack no deposit bonus gives you the chance to enjoy real money online blackjack without dipping into your own pocket.

Bonus Terms and Conditions

Make sure to read the small print before claiming a casino bonus. For starters, you need to know about wagering requirements– this means you have to wager your bonus fund a set number of times before you can withdraw any winnings as cash. It’s also important to know that blackjack games often have a reduced wagering contribution.

This is often 10% to 20%, but some sites exclude blackjack games altogether. Other terms to look out for include maximum winning caps, time limits and game restrictions.

Bonus Calculator

Our bonus calculator tool makes it easy to find out the amount you’ll need to wager in order to meet your bonus’s wagering requirements. Enter the deposit value and percentage, the wagering requirements, the contribution percentage of your favourite game, and whether your casino includes your deposit in the calculation. All of the details you’ll need can be found in your casino’s bonus terms and conditions. Once that’s done, click ‘Calculate’!

Frequently Asked Questions

  • Yes, provided you’re playing at casinos that hold a valid UKGC licence. The UKGC regulates online casinos and ensures that all their games are tested and audited by independent bodies. So whether you’re playing an animated blackjack game powered by RNG, or a live blackjack game with a professionally trained dealer, you can be sure that results are fair when you play blackjack online.

  • At some sites, yes. While certain casinos may restrict the welcome bonus to RNG games, some of the best online blackjack sites let you use bonuses in the live casino- some sites even offer exclusive live casino welcome offers. Read the small print before you claim the welcome bonus, just to avoid any later surprises.

  • No. While playing with optimal strategy can lower the house edge, it’s impossible to predict which cards will be drawn next. This means that you can never guarantee a win when you play blackjack online, regardless of how good your strategy is.

  • To check the return to player (RTP), simply click on the ‘?’ or ‘help’ icon once you’ve loaded up your chosen game. Keep in mind that the RTP is only an average, and your actual return rate can vary depending on both your strategy and the luck of the draw.

  • If you land a win and want to cash in, simply head to the cashier page, select your preferred withdrawal method and request your chosen amount. Keep in mind that most casinos state you need to withdraw via the same method you used to deposit.

  • Side bets like Perfect Pairs and 21 + 3 can offer high payouts, but they’re also much riskier than standard blackjack bets, due to the high house edges and unfavourable odds. Most only require a small wager, and they can be fun for players looking to mix things up a bit, but make sure you check the paytable so you can decide whether it’s worth it for you.

  • Yes. All the best online casinos have a wide range of games, including slots, roulette, poker and baccarat. This means you can enjoy all your favourite games at one best online blackjack site, without having to sign up to multiple casino accounts.

Blacklisted Casinos

Here at TopRatedCasinos.co.uk, we want to help you avoid the worst names in the business as well as showing you the best, so we’ve put together a blacklist of operators to stay away from when you’re looking for a top UK online casino with blackjack.

There are a few reasons we’ll place a site on this list. We urge our players to only use licensed sites, and as such, those without the appropriate licensing from the UK Gambling Commission will automatically find themselves blacklisted. We’re not fond of sites that make it difficult for players to access their funds, so those with convoluted withdrawal processes or lack of payment methods will be blacklisted too.

If you’re playing blackjack online, you want to be sure the game you’re playing is fair. Operators with any involvement in rigged games will also be blacklisted without hesitation — take a look at our blacklisted casinos below.
