Top Blackjack Sites for UK Players in 2025

How We Review the Best Blackjack Casinos

We won’t just recommend any old casino at Compare.bet — our experts select the top blackjack sites using a rigorous set of criteria. Here’s what we dig into when assessing each blackjack site available in the UK.

UKGC Licence

We only recommend blackjack sites that hold a proper licence from the UK Gambling Commission (UKGC). This is our first port of call and any unlicensed operators are immediately blacklisted. Why? Because our players have a greater degree of protection at licensed sites as operators risk fines and sanctions if they fail to meet regulatory standards regarding transactions, player protection and game fairness.

Generous, Player-Friendly Bonuses

Offering a welcome package is par for the course, but not every deal will offer good value to the player. We pick through the terms and conditions of every welcome offered by a site to ensure the terms are player-friendly. That means low wagering requirements, longer time limits, and high winnings caps among other things.

Plenty of Promotions

If you’re going to the effort of signing up to a blackjack casino, there have to be enough incentives to make it worth your time. We assess the value of ongoing promotions for existing players, whether it’s cashback, VIP schemes, or reload bonuses, to make sure that you know exactly what you’re signing up for.

Fast Withdrawals

When you withdraw your cash, you don’t want to be left waiting a long time for it to arrive. While support for the fastest withdrawal methods like e-wallets is a prerequisite here, we also look into the casino’s processing times. Even the quickest payment methods can be hampered if the site takes a long time to confirm the withdrawal.

Wide Range of Deposit and Withdrawal Options

As well as fast withdrawals, we also look for how many payment methods are supported at blackjack sites. We expect to see at least one e-wallet option — PayPal, Skrill, or Neteller are popular options — while support for methods like pay by phone bill or prepaid cards is evidence of a site that caters to a wide range of players. Some particularly innovative blackjack sites will even support crypto deposits and withdrawals. The broader the variety, the better.

Free and Real Money Blackjack Games

There’s an element of skill required to play blackjack. That’s why we love sites that let you play for free, allowing you to perfect your strategy or just play for fun. As such, free play blackjack games are great options for both new and experienced players.

Good Live Dealer Collection

Regardless of whether you have played live dealer blackjack before or not, the best casino sites will give you plenty of choice. This means that games from the best live developers, such as Evolution Gaming and Playtech, are all available to players at a range of buy-ins and minimum stakes.

Blackjack Game Variants

The game of blackjack is centuries old, so it’s no surprise there are lots of variants. Again, choice is the name of the game here. We like to see variants such as American and European Blackjack, Perfect Pairs, Vegas Strip, and Blackjack Switch on the menu, ensuring a wide range of player needs are met.

Customer Service

For the best blackjack sites, great customer support is a top priority. This means providing a detailed FAQs page or online help centre, as well as giving customers a range of options for getting in touch with the team. At leading casino sites, the choice will often include around-the-clock live chat, email, and telephone support. You can sometimes get support via social media channels like Facebook and Twitter too. Either way, we want to see sites respond quickly and accurately to players, and our online casino reviews will let you know what to expect.

Site Design

Appearances matter, and this is as true for online blackjack sites as it is for anything else. The best brands put plenty of thought into how their sites look, incorporating unique themes, high-quality graphics, and easy-to-read content into their designs. We love to see sites boast a fresh new look, but find that even white label picks — where design options are limited — can stand out from the crowd with a few well-chosen tweaks. Top brands offer a distinct look across the board, whether you’re playing on desktop or mobile.

User Experience

While the best blackjack online casino sites come dressed to impress, your overall experience will be about far more than just looks alone. To be one of our top picks, a site must also be easy to get around. Players should be able to find and fire up their favourite real money blackjack games quickly and enjoy them without any lagging issues or glitches — especially where live blackjack games are concerned. The best blackjack casinos make the practical stuff, such as making deposits and opting into promos, a piece of cake too. 

How to Play Blackjack

There’s a huge range of blackjack variations online, each with slightly different rules. However, the aim of the game is always the same: beat the dealer’s hand by getting to 21 first. Of course, you need to do this without going bust – that means exceeding 21. If neither yours nor the dealer’s hand totals 21, the closest hand wins.

1. Join a blackjack game, and place your bet
   Select an online blackjack table. Set your stake to get things started. Each player receives two cards, both face up. In most variations, the dealer also gets two cards, with one face up and the other face down (the hole card).
2. Check your hand
   If you’ve been dealt an ace and a 10 or a picture card, this is called blackjack, or a natural. It means an instant payout of 1.5 times your bet, assuming the dealer doesn’t get one too. Depending on the variation, the dealer may only check for blackjack if their face-up card is a 10, face card or ace. If the dealer also has blackjack, your bet is returned. This is known as a push.
3. Make your move
   If you don’t get a natural, it’s time to make your next move. Depending on your hand, you must decide whether to split, double down, take another card or stick with what you have. In a classic game of blackjack, you can usually hit (ie, take another card) up to three times before you stand, but remember that you’ll go bust if you go over 21. When all players are ready, the dealer reveals their hole card and make their play.
4. The winning hand is revealed
   If your final hand is closer to 21 than the dealer’s hand, or if the dealer goes bust, you win. If the dealer’s hand is closer to the magic number than yours, or you go bust, the dealer wins instead. It’s that simple.
5. Collect your winnings
   If you get lucky, your winnings are credited to your online casino balance immediately. You can carry on playing at the same table, head to another or try another online casino game entirely.

Ready to learn a little more about blackjack rules? From basic and advanced rules of blackjack, right through to the prominent side bets available, we’ve got you covered.

Basic Blackjack Rules

It’s always wise to check the house rules before joining a particular table, but anyone learning how to play online blackjack will need to remember these basic moves.

• Stand
  To stand is to stick with the hand you have. You can stand on your first two cards or after you’ve hit and taken an extra card one or more times. You won’t receive any additional cards once you stand.
• Hit
  Too far from 21? Try your luck with the next card in the deck. This is the way to proceed for players dealt two low-value cards in their first hand. As you know, you can usually take up to three additional cards, but you’ll need to be careful not to go bust.
• Double down
  After seeing your initial hand, you can double down. This means that you will double your initial bet and commit to standing after receiving another card, no matter what that card might be.
• Split
  If you receive two of the same value cards in your initial hand, you can split them into two hands and receive an extra card for each hand from the dealer. If you split, you must place an additional bet on your second hand equal to the value of your original bet.
• 16 and below
  The 16 and below rule only applies to the dealer. The rule demands that dealers hit on any hand with a value of 16 or below.

Advanced Blackjack Rules

Understanding basic blackjack rules will help you get started, but if you’re ready to take your game to the next level, there are some more elements you need to know about too. Let’s look a closer at advanced blackjack rules, including prominent side bets.

• Surrender
  Unhappy with your hand? Available in select variations, you end the game early and forfeit only half your bet. There are two types of surrender: early surrender (before the dealer checks for blackjack) and late surrender (after the dealer has checked their hand).
• Soft 17
  A soft hand refers to any blackjack hand that has an ace in it. It’s called a soft hand because it has two potential values, due to the fact that an ace can be worth either one or 11. Some blackjack variations require the dealer to hit or stand on a soft 17.
• Even money
  It’s always great news if you hit blackjack on your first hand, but if the dealer’s face-up card is an ace, there’s a decent chance they’ll have one too. If you don’t want to risk a push, some new casinos allow you to take the even money option. This means an immediate payout of double your stake and the end of the round. This is a better result than a push, but some players will prefer to decline the even money option in the hope of a bigger return if the dealer turns out not to have a blackjack.
• Insurance
  If the dealer’s up-card is an ace, an insurance wager may be offered. It’s similar to the even money option we mentioned above, except this is offered when you don’t have a natural blackjack. And, instead of accepting an instant payout that finishes the round, you’re placing a new side bet wager at 2:1 that the dealer’s initial hand is a natural. If it isn’t, you lose the side bet but the round continues as normal.
• 21+3
  This blackjack side bet pays out if your first two cards and the dealer’s up-card combine to form one of five three-card poker hand: a flush, straight, three-of-a-kind, straight flush or suited three-of-a-kind. Your payout depends on which of the five hands you get.
• Perfect pairs
  This is a side bet where you put money on your first hand being a pair. Payouts depend on whether you get a mixed pair (same number/face card values, different colours and suits), a coloured pair (where only the suits differ) or a perfect pair, which are identical.
• Bet behind
  This is a bet on another player’s hand commonly offered to players waiting for a seat at the table of live blackjack games. Standard payout ratios apply.
• Royal match
  The Royal Match bet is one of blackjack’s oldest side bets. This bet offers odds of 5:2 for a suited pair and a premium payout of 25:1 if you land a king and queen from the same suit.

Blackjack Card Values

Blackjack card values are pretty self-explanatory. Cards 2 through 10 are worth their face value, while face cards (jack, queen and king) are each worth 10. Aces are worth either 1 or 11, depending on which gives you the best hand.

Blackjack Payouts

Standard blackjack games pay out 3:2 for blackjack, which means you’ll receive 1.5 times your bet if you hit 21. If you don’t make 21, but still beat the dealer, blackjack pays out 1:1. Some games such as Blackjack Switch have rule variations that are beneficial to the player, and this advantage is often evened out by a reduced payout for natural blackjack wins.

The chances of winning at blackjack vary depending on the blackjack game you’re playing. Factors such as the number of decks of cards in play, if surrender is allowed, and when the dealer must stand all impact the blackjack house edge.

Blackjack has a pretty low house edge, which is part of what makes it so appealing. The house edge for regular blackjack is less than 0.5% when you play according to basic blackjack strategy, so take time to clue up before you start playing.

Get to Grips with Basic Blackjack Strategy

There are sets of time-honoured rules that determine the best moves to make in blackjack, based on the numbers of decks in play and your particular hand. Let’s look at some of the most common blackjack strategies you can use to help you win a payout.

• Don’t split 10s or face cards
  A common mistake by rookie players is to split two 10s or face cards. Contrary to the belief that this can double your profits, you’re actually playing with fire by giving up a highly formidable 20 hand in the hope of getting dealt favourable cards.
• Double down on hard 11
  Basic blackjack strategy deems a hard 11 as one of the most powerful hands in the game. A hard 11 is simply a combination of two number cards that add up to 11. Doubling down on any dealer up-card (other than an ace if the dealer must stand on soft 17) will put you in a better position than if you simply take another card.
• Always splits aces and eights
  By splitting a pair of eights, you swap a disappointing hand value of 16 for the chance to improve both hands with a face card. Similarly, a pair of aces will give you a disappointing hand value of 2 or 12, so it’s far better to split the hand in two and hope for a new high-value card for each hand.
• Double down on 10 if the dealer’s up-card is nine or less
  If you get a 10 with your initial hand, you should double down if the dealer’s up-card is nine or less. You are the favourite in this situation and should always try to capitalise on your advantage.

Wager Using these Online Blackjack Tips

While blackjack tips won’t tell you how to win, they can stand you in good stead when you sit down at the virtual blackjack table. Here are some to keep in mind as you pursue that fabled number of 21.

• Make sure you understand exactly how your chosen blackjack game works and how to play using basic strategy. Don’t worry about having to memorise this, as there are strategy charts freely available online to help you out.
• New players should try free play blackjack first. This will help you get some practice in before you play real money games. If you decide to play more unusual or niche blackjack variations, it’s particularly important to try the demo games first so you understand how the games work before risking your cash.
• Some online casinos deviate from standard payouts and offer odds of 6:5 instead of 3:2. The house edge is bigger in games with 6:5 odds, paying out £12 on a £10 wager rather than the £15 you’d get for an untied wager on blackjack that pays 3:2. For this reason, it’s best to stick to games with standard odds.
• Always stick to the budget you set yourself and never bet more on online blackjack than you can afford to lose. Licensed online casinos must give you the option to set deposit limits, and it can be a good idea to take up the offer.
• Know when to quit. There’s always another day and another game. Gambling responsibly is one of the best things you can do when you play any real money casino game online.

History of Blackjack

Blackjack is one of the most popular casino games and is played all around the world. Wondering where it all began? Well, no one knows for sure — but it’s believed to have originated in France way back in the 17th century as the game ‘Vingt-et-Un’. 

Fast forward to the 18th century, and Vingt-et-Un hit the shores of North America, brought across the Atlantic by French colonists. There, it became popular in gambling establishments, particularly in New Orleans. As the game spread, it became known as ‘blackjack’ on account of a bonus payout offered by some casinos, won if the player held the Ace of Spades and a Jack of Clubs or Spades — in other words, a black Jack.

The 1900s saw the ban of nearly all gambling across the US, although blackjack remained a staple at underground speakeasies during the Prohibition era. In 1931, Nevada legalised gambling. As casinos began to flourish in Las Vegas, they began to implement standardised rules and odds, shaping the game into what it is today. Mathematicians like Edward O. Thorp took a keen interest in the game, developing strategies like card counting in the 1960s.

By the turn of the century, online gambling had established itself as a new way to play, and wider access to blackjack further bolstered its popularity. The game continues to evolve, with new variations being developed to keep things fresh and exciting.

The Different Blackjack Game Types

Now that you have a good idea about blackjack rules and card values, you may be itching to put that knowledge to the test and play blackjack online. But hold on – there are some diverse gameplay options to keep in mind. Here are some popular blackjack variations available at top UK casinos right now.

American Blackjack

This is the most widely played form of the game. For this reason, it’s often referred to as classic blackjack. American blackjack games follow the basic blackjack rules and are available almost universally at online casinos.

European Blackjack

The European game comes with some subtle differences in the rules. For example, the dealer doesn’t get their hole card until all players play their hands. That means the dealer won’t know if they have blackjack until after the players have made their moves. Additionally, players can only double down on hands with values between nine and 11, and they can split 10s or face cards only.

Vegas Strip Blackjack

Taking its name from the stretch of Las Vegas Boulevard known for its glittering casinos, Vegas Strip Blackjack is a popular pick for players of the classic card game. This variation is practically the same as the general American version, except that it’s always played with four decks and the dealer can only take a peek at their initial hand if the up-card is an ace.

Atlantic City Blackjack

This is yet another variation on the American game, with the main distinguishing factor for Atlantic City Blackjack being the fact that it’s played with eight decks instead of the four used in the Vegas Strip version. Players may also opt for a late surrender.

Blackjack Switch

Imagine having two blackjack hands and being able to swap the cards between them to make two better hands. Sound good? That’s exactly what Blackjack Switch is all about. In this variation, you play two hands and can switch the second card of each. Another important rule to remember is that the dealer can get 22 and only go bust if a player hits blackjack without using a split or switch.

Highest Paying Blackjack Games

Gambling should be about having fun, not making money. That said, maximizing your bankroll and improving your chances of a return is important. One way to do this is by choosing blackjack games with the lowest house edge or highest return to player (RTP) percentage.

Unlike slots or roulette, blackjack involves skill. You can lower the house edge by using basic strategy or playing games with favorable rules. For instance, single-deck blackjack typically has a lower house edge than games using multiple decks, resulting in a higher RTP.

In classic blackjack, a blackjack pays 3:2, or 1.5 times your bet. Winning with a hand closer to 21 than the dealer’s or when the dealer busts pays 1:1. If there’s a tie, your bet is usually returned.

Highest Paying Live Dealer Blackjack Games

In the table below, we’ve rounded up some live dealer blackjack games with the best payouts. These games are run by a professional dealer from a real studio or casino and streamed directly to your device — many of these titles are available at our recommended blackjack sites.

Highest Paying RNG Blackjack Games

RNG games are virtual and players have full control over the pace of the game, so they’re a great way to perfect your strategy. After all, that’s one of the most effective ways to maximise your returns. The RNG blackjack games below have some of the best RTPs on account of their favourable rules — once you’ve got your strategy down, they’re a great place to start.

Different Blackjack Games Available

There are many variants of blackjack — after all, it’s one of the most popular casino games — and some might be more suited to your playing style than others. Here’s a rundown of what you might find at the best online blackjack sites. 

American Blackjack

You can pretty much think of American blackjack as the ‘standard’ version of the game. To begin, the dealer receives two cards — one face up, one face down — and each player is dealt two cards face up. Players can hit or stand, and the rules generally allow for double down, split, and surrender. Some American blackjack titles also include the insurance side bet. 

In this variant, the dealer checks for blackjack if their upcard is an ace, and must hit on soft 17 and stand on hard 17. American blackjack is usually played with 6–8 decks.

European Blackjack

In European blackjack, the dealer only receives one card at first, and waits until the players have played their hands before receiving a second card and playing their own — so they can’t check for blackjack at the start of the round.

Players may only double down on hands with a total value of 9, 10, or 11, and can only split once during a hand. European blackjack players usually don’t have the option to surrender, either. Despite being a slightly more rigid form of blackjack, the European game is played with only two decks of cards, which significantly reduces the house’s edge over players.

Blackjack Switch

Blackjack switch shakes up the traditional blackjack format substantially — players are dealt two hands instead of one and can switch their top two cards, adding another layer of strategy to the game. Another twist? The dealer doesn’t bust if their hand totals 22. Instead, the round ends in a push unless a player has made a blackjack without switching or splitting. 

All other blackjack variables — like splitting or number of decks — depend on the game. For example, Playtech’s Blackjack Switch is played with six decks and allows its players to both split and double down, which explains why it carries a staggering RTP rate of 99.92%.

Vegas Strip Blackjack

Vegas Strip blackjack gets its name from the iconic casino boulevard, and is actually just a slight variation of the American format. The game is played with four decks of cards and the dealer must stand on soft 17. Vegas Strip players are also allowed to insure their hands against a blackjack if the dealer’s first card is an ace, and this insurance side bet pays out at 2/1 if the dealer ends up making blackjack. 

Blackjack Perfect Pairs

Blackjack Perfect Pairs includes a side bet based on the player’s first two cards and whether they make a certain combination:

• Mixed Pair – two cards of the same value, but in a different suit and colour.
• Coloured Pair – same value and colour, but in a different suit.
• Perfect Pair – same value, colour, and suit.

Perfect Pairs can be played with anywhere from two to eight decks of cards. Rules around splitting and doubling down depend on the specific title.

Free Blackjack

The best UK online blackjack sites offer free blackjack titles, allowing you to get acquainted before staking your own cash. These free games are a great opportunity to figure out which variant suits you best and to work on an optimal strategy before trying your luck at the real thing. Alternatively, free blackjack games can be a great way to unwind without worrying about losing any money.

Whatever your motive, free blackjack is available at most blackjack casinos. You only need to sign up to play, with no real-money deposits necessary.  A number of the top UK blackjack sites we recommend – such as HeySpin, Grosvenor Casino and Unibet – offer free blackjack to both new and returning players. 

Unfortunately, you can’t play live dealer blackjack for free, but you can spectate on some live dealer games to get a feel for how it all works before giving it a go yourself.

Blackjack Games at UK Casinos

When it comes to games libraries, not all casinos are created equal. We’ve highlighted some picks below with a decent selection, giving players access to different variants and live dealer games.

Improve Your Game with Blackjack Strategy

Using an optimal blackjack strategy is fundamental to lowering the house edge. Basic strategy guides and tactics illuminate the best moves depending on the player and dealer’s hand strengths. While this cannot guarantee a win, it can significantly lower the house edge. 

A few fundamental rules to consider include: 

• Always hit on a hard 17 
• Always split your 8s and aces 
• Stand if your hand value is 12-16 compared to the dealer’s 2-6 
• Hit if your hand value is 12-16 and the dealer possesses 7-ace 
• Double down on an 11 if the dealer has 2-10 
• Stay away from the insurance bet 
• Consider using the surrender if your hand contains a hard 5-7, hard 12-17, or pairs of 3s, 6s, 7s, or 8s 
• Look up online blackjack strategy charts to know the best moves depending on position 

Understand the Cards

Blackjack is a pretty straightforward game; you try and get as close to a score of 21 without going over or “busting”. However, if you do not understand the cards, it gets much trickier. Make sure when playing blackjack you have a full understanding of the value of each card. Take a look at the guide below to help you out.

• Number cards are at face value. For example, if you draw a 9 that card has a value of 9.Face cards are always worth 10.
• Face cards include Jacks, Queens and Kings.
• An ace in blackjack can be worth either 1 or 11, depending on what best suits your hand. For instance, if you draw an 8 and an ace, your total is 19. On the other hand, if you draw a 10, a 6, and an ace, the ace counts as 1 to prevent you from busting, giving you a total of 17 instead.

Try out Different Blackjack Variations

There are a wide range of exciting game variations available at the UK’s best blackjack sites. Let’s take a look at the top titles on offer.

Blackjack surrender – This variation allows you to cut your losses if you don’t fancy your first hand by only losing half your bet. While most games don’t allow you to surrender if the dealer gets a natural, a few variations do – this is known as early surrender.

Blackjack switch – In blackjack switch, you’re dealt two hands instead of one. You can choose to switch the second cards of each hand to create the strongest possible hands.

Double exposure – Here, both the dealers cards are face up. This is an advantage for the player, but casinos make up for this by offering slightly lower payouts. In this variation the dealer also wins on ties unless you land a natural.

Pontoon – This is essentially the opposite to double exposure – both the dealer’s cards are face down. This obviously makes things more difficult for the player, but in exchange there’s an increased payout for natural blackjack of 2:1 rather than 3:2.

Multi-hand blackjack – This variation uses the standard blackjack rules but lets you play multiple hands at once. Some games even allow you to play up to five hands at a time.

Spanish 21 – A unique blackjack variant that sees all the number 10 cards removed from the shoe of six decks in play. Players’ hands are often made up of lots of low cards as a result, which gives a much wider selection of side bets, such as a 7-card hand at 3/1. In Spanish Blackjack, a player’s blackjack or 21 always wins. 

Vegas Strip Blackjack – A slight twist on American blackjack, Vegas Strip is always played with four decks of cards. Players can buy insurance, which pays out at 2/1, and the dealer stands on soft 17. Many players prefer Vegas Strip blackjack over American blackjack as these rules mean the game has a lower house edge.

Progressive Blackjack – Popularised by online slots like Mega Moolah, progressive jackpots are where a portion of each bet goes into the jackpot pool, steadily increasing the amount until it’s won. In the case of progressive jackpot blackjack, players must usually make a specific side bet to be in the running to swipe the jackpot. Usually, the jackpot is triggered when your cards and the dealer’s combine in a specific way — for example, four aces of the same colour. 

Mix Things up with Blackjack Side Bets

Many online blackjack games have optional side bets that you can wager on as well as wagering on your hand. These bets are separate to the main game and are based purely on luck. Side bets are popular because they offer high payouts if you get lucky. The side bets on offer vary depending on the blackjack game you’re playing, but here are the most popular:

Perfect pairs – This is a bet that your first two cards will be a pair. The payout depends on the strength of the pairing – a ‘perfect’ pair of the same rank and suit usually pays out 25:1, while a red and black pair typically pays 6:1.

23+1 – Here you’re betting that your first two cards and the dealer’s hole card will form a flush, straight, three of a kind, straight flush or suited three of a kind. Again, the payouts depend on the strength of the hand. For example, in Playtech’s All Bets Blackjack, a flush pays out 5:1 while a suited three of a kind pays out 100:1.

Insurance – If the dealer’s hole card is an Ace, you can insure your bets against the dealer by placing an insurance bet equal to half the amount of your initial wager. If the dealer does have blackjack your insurance bet pays 2:1, meaning you don’t lose your original bet.

Progressive – Some blackjack games offer a progressive jackpot sidebet. In most progressive blackjack variations, this involves betting on Aces. Depending on the variation, you may need to draw four consecutive Aces of the same suit to land the jackpot.

Enjoy an Immersive Live Blackjack Experience

Fancy a more realistic game of blackjack? Live dealer blackjack is as close as it gets to being at an actual land-based casino. The top live games are streamed in HD from purpose built studios, so they look and feel just like the real thing. Games are also run by professionally trained dealers using authentic equipment, making for more immersive blackjack gaming.

The UK’s best online blackjack sites host a wide range of tables to choose from. There are different variations on offer, with different side bets and betting limits, including low stakes games. Live dealer blackjack games are also a great option for high rollers, as the top sites host exclusive VIP tables, some of which allow you to bet as much as £20,000 per hand.

The Best Blackjack Software Developers

A number of the top casino software providers have developed online blackjack games. As casinos often use different software, the blackjack titles on offer vary from site to site, so knowing the differences between providers can help you find the best blackjack site for you. Here are the developers responsible for the top blackjack titles:

NetEnt

NetEnt is one of the biggest casino software providers and has developed a range of both animated and live dealer blackjack games. When it comes to RNG blackjack titles, NetEnt has developed games like Pontoon, Single Deck Blackjack and Double Exposure Blackjack. NetEnt also offers great live dealer blackjack tables, including the industry-first Perfect Blackjack, which deals cards according to perfect blackjack strategy. There’s also Common Draw Blackjack, which caters to an unlimited number of players at each table.

Top NetEnt Online Blackjack Games

Single Deck Blackjack Professional Series
Single-deck blackjack games come with a lower house edge than the usual four or eight-deck games, although this NetEnt title has rather conservative betting limits. A blackjack pays 3:2 and players can buy insurance as well.

What we like: 

• Lower house edge means higher RTP

What we don’t like: 

• Lower betting limits won’t suit all players

Blackjack Classic
NetEnt’s no-frills offering, Blackjack Classic, stays true to the game’s roots. It’s played with four decks, and the dealer draws to 16 and stands on all 17s. Players can double down and also buy insurance.

What we like:

• Solid core gameplay suits beginners and experts

What we don’t like: 

• Lack of side bets may disappoint some

Double Exposure Blackjack
In Double Exposure Blackjack, both dealer cards are dealt face up. Unfortunately, this advantage is mitigated by some restrictive rules, including blackjacks paying even money while the dealer wins all non-blackjack pushes.

What we like:

• Face-up dealer cards gives players an advantage

What we don’t like:

• This advantage is removed by rules that favour the house

Evolution Gaming

Evolution Gaming is the leading provider of live casino software, so naturally its blackjack offering is top-notch. From low stakes Blackjack Party and Infinite Blackjack to VIP Salon Privé tables, there’s something for players of all budgets. Evolution’s live blackjack tables offer the Bet Behind feature which allows you to place bets on players’ hands while you wait for a seat, as well as side bets on perfect pairs and 21+3. These games are also some of the most realistic live blackjack games you can play at online casinos.

Top Evolution Gaming Blackjack Games

First Person Blackjack
Bucking Evolution’s trend of live dealer games, First Person Blackjack is an RNG game set in a realistic 3D environment. As such, it is one of the closest experiences you’ll come to the real thing in a virtual game. Players can also make Perfect Pair and 21+3 side bets.

What we like:

• Players can control the pace of the game
• Includes side bets

What we don’t like:

• RNG rather than live dealer

Lightning Blackjack
Lightning Blackjack throws RNG multipliers into the mix to boost your payouts. Win a round and you’re granted a random multiplier between 2x and 25x for the next hand, giving you the possibility of a larger prize.

What we like:

• Multipliers add an exciting twist and boosted payouts

What we don’t like:

• Additional Lightning Fee required to unlock multipliers

Power Blackjack
Part of Evolution’s Infinite range, Power Blackjack shakes things up considerably by allowing unlimited players at the table. Players can make four side bets — Any Pair, 21+3, Hot 3, and Bust It — as well as double, triple, or quadruple downs on any two initial cards including after a split. The trade-off? It’s played with eight decks with the 9s and 10s removed, so normal blackjack strategy is out the window. 

What we like:

• Unlimited players can join
• Four different side bets

What we don’t like:

• 9s and 10s removed from the deck so normal strategy doesn’t apply

Playtech

Play Blackjack on Your Mobile

Mobile blackjack casinos are far more popular than desktop platforms nowadays, offering players a convenient way to stand, hit, double, or surrender from their smartphones. Software developers optimise their titles for iOS and Android devices, enhancing the graphics for smaller screens and making use of landscape/vertical modes. Whether you’re looking for vintage video blackjack or next-gen live dealer variants, everything is easily accessible from your smartphone. 

All the best online blackjack casinos have mobile-optimised websites, but the cream of the crop also offer bespoke mobile casino apps. The next section will illuminate some of the pros and cons of using these.

Play Real Money Blackjack with a Casino Bonus

Loads of the UK’s best online casinos offer bonuses that you can use to play at real money blackjack tables. Fancy bagging one for yourself? Let’s take a look at the top bonuses on offer when you sign up to the best online blackjack sites.

Terms and Conditions at Blackjack Sites

At first glance, a blackjack bonus might seem rather enticing. But to get a clearer picture of its true value, you’ll need to read the terms and conditions — these can quickly diminish the worth of an offer if they’re overly strict. Below are some common terms to watch out for. 

Wagering Requirements

Wagering requirements often have the biggest impact on bonus value, as they prevent you from withdrawing the bonus and resulting winnings until they’re completed. Expressed as a multiple, this is the number of times you need to wager the value of the bonus with your own money before it becomes withdrawable. 

For example, a £10 bonus with wagering requirements of 30x would necessitate betting £300 of your own cash before it can be withdrawn along with any related winnings. 

Game Weighting

A term closely tied to wagering requirements, game weighting is the amount that bets on a certain game contribute towards meeting said requirements. Table games like blackjack and roulette usually come with low weightings of 10% or sometimes nothing at all, meaning you’ll have to bet more or pick a different game entirely if you want to chip away at the required playthrough amount.

Game Restrictions

Unfortunately, it’s rare you’ll get carte blanche to use your bonus on any old game you like. The restrictions depend on the bonus. Matched deposits are typically the most flexible offers, but you could still find categories such as live dealer games aren’t eligible. In the case of blackjack, games with particularly low house edges — single-deck blackjack, for example — may be excluded too.

Payment Exclusions

If your bonus requires a qualifying deposit in order to claim it, be sure to use an eligible payment method. Common exclusions include e-wallets and sometimes prepaid cards, while debit cards are always eligible. 

Winnings Caps

Most bonuses come with a winnings cap, stipulating the maximum amount you can withdraw from an offer. The cap is generally proportional to the size and terms of the bonus — a £20 deposit match may have a winnings cap of around £100, for example, while 20 no deposit free spins could be much lower at just £10. 

Time Limits

All bonuses come with a time limit, which could range from just 24 hours to a full month or more. Be sure to use your bonus within this time, or you’ll forfeit any unused portion. Wagering requirements must also be met within this time limit if you want to withdraw your winnings.

Blackjack Betting Systems

Like all casino and gambling games, blackjack is a game of chance. Guaranteeing success with an optimised strategy is unrealistic, but this doesn’t mean you cannot considerably improve your chances and make your bankroll stretch as far as possible. 

Blackjack enthusiasts have devised several betting systems since the 16th century that can help you reduce the house edge, effectively manage your gambling funds, and make the optimum decisions. 

Check below for a breakdown of the most useful blackjack betting systems to employ: 

Flat Betting

Flat betting is an easy way to manage your gameplay, and it’s a popular blackjack system with many UK players. This method follows the idea of wagering the same amount with every hand, thus lowering any risk of erratic play and maintaining a close watch on your wagering total. Each individual will have a different flat betting amount, based on personal budget, and for how many hands they intend on playing. Let’s say you have a £50 budget and want to play 20 hands, meaning your bet would be £2.50 per hand. 

Positive Progression

The main idea of the positive progression system is to increase your bet with each hand you win. When your winning streak comes to an end, you return to your initial bet and stay here until you win again. Using a positive progression system on blackjack sites ensures players make the most of their wins but minimise big losses by returning to careful bets.

You should be mindful of the bet increase to opt for and recognise when it’s time to stop playing. Budget management is important, as is remembering what limits you set for yourself in terms of spending and time played. 

Negative Progression

Another favoured betting system at the best blackjack sites is negative progression, which is the opposite of positive progression. Riskier in its approach, UK players who choose this strategy increase their bet size following a losing hand. Ideally, this means you’ll immediately win back your losses after the next winning hand. 

This method is best suited to players with large bankrolls, but it can be a dangerous game to play if you are on a lower budget. You may not encounter a winning hand for several rounds, by which point you could be completely out of funds. Keep this in mind and know when to cut your losses if you intend to play with a negative progression system.
