A comparison

When it comes to finding the best place to play online blackjack, it’s not simply the products that are important. You also need to consider the RTPs, table limits and bonuses that are available. It’s also crucial for you to understand as much as possible about the game.

For in-depth explanations of the rules, strategies and history, you can look through my other blackjack articles.

The Best Blackjack Sites

A good game selection is the principal factor in identifying a good blackjack casino. A varied game library is a plus and the best blackjack sites will offer welcome bonuses with conditions that favor all gaming products as well.

These five online blackjack sites are the top options that meet these criteria, while also meeting my safety, licencing and security requirements.

There are a lot of other intricacies to the popular card game that I have separated into their own holistic articles, which you can peruse at your leisure simply through the navigation buttons below.

What Makes These Blackjack Casinos the Best?

The market is flooded with online casinos where you can play online blackjack, but not all of them are worth your time. The top five you see above are all licensed by the United Kingdom Gambling Commission (UKGC) as having a fair and safe gaming environment.

As well as meeting high fairness standards, which I’ll discuss in another section, they have also not just met, but exceeded expectations in five other important factors.

Let’s get some more details on these five criteria in the sections below, where you will learn all about the different variants of the game, how to identify a decent bonus, what constitutes good customer service and the differences between the live and online versions that are out there.

The Online Blackjack Sites and Game Selections

Good casinos should have a wide selection of different online blackjack products. In fact, there are very few blackjack casino sites who will only provide the base game and nothing else. Alongside the base game you’ll find many variations that slightly tweak the rules.

For example, there are variants where the player must take back their chips if the result is a tie, or ones where you can switch cards between your two hands. Try out the demo game below for free.

The Classic Blackjack Gold game demo by Microgaming.

There are lots of new and innovative variants online which are worlds apart from traditional versions. Take, for example, Playtech’s 21 Duel Blackjack, which changes how cards are dealt. Also, the maximum number of cards that are permitted in a hand is three.

Another interesting variant is Blackjack Switch. In this, you play with two hands and have the option to switch your top cards between hands to improve your chances of winning. Below you can find the most popular titles available online. Read full reviews and to try your favourite in demo mode.

The above selection is just an introduction to the different online blackjack varieties that are available out there, but it does a fantastic job at highlighting the creations of the industry’s leading software developers such as powerhouses Microgaming, Playtech and NetEnt, alongside up-and-coming Reading-based firm Realistic Games.

Exceptional Blackjack Variants Exclusive to Online Casinos
  • Cards are dealt on a green table for a player and a dealer in the Crazy Blackjack Game.1/8 Crazy Blackjack This game includes three incredible side bets. There is the Highest Hand Bet, where you predict the highest hand to get paid, the Safe Bet, where the worst of hands will pay out, and the 777 Jackpot Bet, where you can win a huge jackpot prize.
  • A player's hand in Spanish 21 shows a total of 18 against a dealer's 10 and hole card.2/8 Spanish 21 In this variant, all 10s are removed from the deck. Doubling after splitting is allowed, as is the re-splitting of aces, and the player is allowed to split three times. Plus, there is the option of late surrender.
  • A game of 21 Duel with two community cards.3/8 21 DuelThis innovative title has two community cards in the centre of the table. The player and the dealer must both choose one of the cards to play with after their cards have been dealt. There is an optional 2Up side bet available in the game.
  • Blackjack Switch, with the possibility to switch cards between hands.4/8 Blackjack SwitchUndoubtedly one of the most innovative variants of the classic. In this variant, you play with two hands simultaneously. When the cards are dealt, you have the option to swap your top two cards to create the optimal hand.
  • Double Attack Blackjack, in-game view showing a purple table ready for the player to place their bet.5/8 Double Attack Blackjack As with Spanish 21, a 48-card deck is used in this variant, with the 10s removed. After the dealer’s first card has been drawn, you can place an additional bet. Also, the Bust It! side bet allows you to bet that the dealer will go bust with his/her third card.
  • Double Exposure Blackjack, in which you can see everyone else's hands including both of the dealer's cards6/8 Double Exposure Blackjack Unlike the classic game, in this variant you see everyone’s cards as they are dealt. This enables you to make clearer decisions on when to hit and when to stand, as you already know the dealer’s hand.
  • In-game view of Blackjack Pontoon showing the player winning with 20 against a dealer's 18.7/8 Pontoon One of the best known variants, Pontoon features several changes to the usual rules. For starters, there are different names for Hit, Stand and Double – though the moves remain. You can only stand if your hand total is 15 or more, and you can split if you have two matching cards.
  • Playing a hand of the Deal or No Deal Blackjack game by Red Tiger.8/8 Deal or No Deal Blackjack This is a twist on the option to surrender that is offered in some variants. The game follows standard rules, offering you a cash amount at each stage for you to take if you want, but that means giving up your hand and its potential winnings.

It is always a good idea to read the rules of every version before you begin to play, as small differences can be found even in two games with the same name. These differences may seem small, but can make a huge difference.

Live Blackjack Sites with Real Dealers

Take a look at some of the most popular live blackjack games in action.

Casino games with real dealers are extremely popular, and pretty much all live casinos provide numerous different tables. However, there aren’t many special variants of this game available in the live stream.

Apart from the classic version, you might find Blackjack Party from leading live developer Evolution Gaming, which significantly plays up the fun factor. While it follows the usual basic rules, the entertainment is taken to a whole new level with not one, but two dealers at the helm.

They’re typically quite chatty and upbeat, with lots of banter up their sleeves. This live table takes stakes from as low as 50p, so low rollers and casual players will appreciate this setup.

You can also let the choice of dealers guide your selection, and check for any desired side bet options. The chat functionality is available in all live offerings, so you won’t ever be left hanging if you feel like socializing while playing.

If you are interested in playing live, two of the best choices are 888casino, and BetVictor offers more than 35 different live tables.

Playing Blackjack on the Move

As the popularity of smartphones and tablets continues to grow exponentially, blackjack has become increasingly popular on portable devices, as result, the best blackjack games can be found on mobile devices.

Many of the RNG-based blackjack products are developed using mobile-friendly code language HMTL5, which means you can play them directly in your browser window without needing to download an app.

Many operators also have dedicated apps that you can download for iOS or Android, but mobile-optimised blackjack sites are the way of the future. However, this is a relatively new development and so there are fewer casino games available on a mobile casino than on a desktop version.

Much more information on this topic can be found in this mobile blackjack article, which gives you recommendations on the best apps for blackjack.

Lots of Payment Options Available

Included in important criteria for being heralded as one of my top six blackjack casinos is ease of use in all aspects, such as its payment systems. Having a good variety of options for its users to choose between when making a deposit or withdrawal is a good first step.

I have made sure to include operators that, of course, offer credit cards as a standard, as well as accepting eWallets and prepaid debit cards such as paysafecard. One of the most popular methods of payment for blackjack players is PayPal.

Best Blackjack Casino with PayPal Deposit Use the popular eWallet and join a table
£50 Welcome Bonus
Full T&Cs apply. New customers only. Opt-in required. 100% Match Bonus up to £50 on 1st deposit of £10+. 50x bonus wagering applies as do weighting requirements. Debit Card & PayPal deposits only. This offer is valid for 7 days from your new account being registered.  Irregular gameplay may invalidate your bonus.

PayPal has become a go-to option for leading operators thanks to its usability, immediacy and simplicity. The operator above is a great option as one of the best online casinos with the eWallet option, where you can fund your real money gaming on many variants with ease.

Alongside these popular and well-used methods are some newer alternatives, such as paying with Bitcoin. This is still a pretty new system for the industry so I won’t go into too much detail, but you can read more about it here.

Picking Favourable Bonus Conditions

A bonus that is specifically provided for blackjack is a rarity. However, many welcome offers for new players can be used to play online blackjack.

When looking out for a good bonus, it is not simply the amount you get that you should pay attention to. Having favourable conditions is much more important since this is something that will determine how useful a welcome offer will actually be.

Any awarded sum will need to be turned over a certain number of times before you can withdraw any winnings you have made with it, and this wagering requirement varies from one operator to another. You can see details like this and a list of casino bonuses on our dedicated page for bonuses.

  • *Setting autospin to 500 consecutive spins may result in winning confiscation
  • **Roulette bets covering more than 25 or more numbers on the table do not count.

Also, keep in mind the fact that games with a low house edge will only contribute a small percentage towards meeting the wagering requirements. Since online blackjack has one of the lowest house edges of all offerings, only a small portion of your wagered money will count towards fulfilling the playthrough requirements.

Some operators exclude blackjack wagers from playthrough contributions altogether. Therefore, what you should aim for is a casino that will contribute 10% – 20% towards wagering. This can be considered good value for the player, within the scope of options.

It is highly unusual to find higher values than this. Promotions where it counts for less than 10% are simply a waste of your time. It would almost certainly cost you money in the long run.

Claiming a welcome offer at an online casino is a choice that you can make, and you are not required to do so. If you have selected a good operator for your gaming experience but aren’t interested in the promotion, or if it has tricky bonus conditions, you can opt-out of the promotion on registration.

To save a bit of time, look for Playtech casinos when trying to spot favourable conditions. On sites like Ladbrokes or William Hill, most blackjack titles contribute 20% towards wagering requirements.

One of the best bonus options for this game is at Betfair, where it contributes a huge 50%. This sum is as yet unmatched by any other operator. If you get tired of the card tables, you’ll have a huge choice in other categories, each with plenty of innovative variants.

888casino also provides a generous welcome bonus, and a big selection of unique promotions specifically tailored towards live streaming card tables.

Extra Promotions, Plus Loyalty and VIP Programs

The best operators out there will have other types of bonuses available other than just the welcome offers. Many will have seasonal promotions for a short period, time-specific deals on particular days of the week or offers that highlight gameplay styles.

These change quite frequently due to the nature of the promotions, so the promotions in the table below are purely examples. However, the operators listed in my top six blackjack online casinos are well-known for having these kinds of promotions, so check them out and see what’s current.

Examples of Promotions for Online Blackjack
  • The 888casino 21st of the month promotion. Deposit £20 or more at 888casino on the 21st of the month to get £300 Free Play money to use in Multihand Blackjack. 1/3
  • The Mansion Casino Side Bet Insurance promotion. Mansion Casino will give players a 20% cashback up to £100 on Live Blackjack side bets during the weekends. 2/3
  • The Beat The Dealer promotion at Casino.com Hit blackjack in successive hands to ‘beat the dealer’ and win cash from Casino.com. 3/3

Due to the relatively low-risk nature of blackjack at online casinos, the house edge is one of the tightest out there. The potential for players to win money makes the operators less generous with the promotions and bonuses, so there are not a lot of fantastic bonuses around.

Table limits

When it comes to sticking within your budget, the thing to look out for is the table limits. There are typically both standard and high roller tables available in both live and RNG-based games, and limits are displayed conveniently with each available table.

The table limits are set by each operator, with different developers allowing different limits based on the type of partnership they have.

In a brick and mortar casino, table limits are usually quite restrictive – the bet range typically sits between £5 – £100. Online, however, there are betting limits for all types of players. Low stakes games sometimes start from as little as 10p per hand, while some operators offer premier tables for only those with the deepest pockets.

Look no further than LeoVegas or 888casino, where stakes of up to £10,000 can be placed once you step into the VIP lounge.

Other Games Found at Blackjack Online Casinos

Even though playing blackjack may be your number one priority, the best online casinos will also have other games available to play than just the one card game. In fact, my top 6 casinos will all have anywhere between 200 and 1,000 different titles on their websites.

A woman rakes in the winning chips on a roulette table next to a collage of different casino game promotional images.

Most of those hundreds of games are slots, and you’ll also find selections of roulette and poker varieties as well. This way, if you ever need a break from blackjack or just a little bit of something new to try, you’ll be spoilt for choice. For the sites that perform well across the board, see our best online casinos list.

How to Recognise if Blackjack Games Are Fair

In addition to a varied game selection and a good bonus, the other important consideration with online casinos is fairness and security. You need to be sure that you choose a blackjack site with a valid licence from the UK Gambling Commission.

This government body strictly monitors and regulates online casinos active on the UK market, with the aim to ensure that players are protected, including checking for security measures like data encryption, transparent payment processing, and regular testing of fairness through an accredited testing agency.

Another way to check for fairness is to keep a close watch on the payout rates. All titles should have a very low house edge, meaning the return to player rate (RTP) can be relatively high – usually above 98%.

This is very rewarding compared to roulette, which ranges between 94% – 98%, and slots, which can range from around 90% – 97%.

Reputable organizations such as eCOGRA and GLI produce reports showing the actual percentage of all money wagered across games that have been paid out in winnings. Often, you’ll see the logo of the testing agency in the footer of the blackjack site, and some casinos even let you access their latest testing reports directly, by clicking that logo.

You should, however, bear in mind that these results include wagers on all titles, including side bets. Therefore, the average payout rate will likely be lower than the 98% or more than you can usually expect. However, the overall RTP should still be over 99%. These figures confirm the fairness and integrity of the games.

Top Payouts – Games Top Payouts – Side Bets
99.87% Blackjack Switch 97.92% Hi Lo (6 Decks)
99.66% Blackjack Surrender 97.78% Super Split (8 Decks)
99.64% Pontoon 97.69% Kings Bounty (6 Decks)
99.64% Perfect Pairs Blackjack 97.45% Super Match
99.53% Progressive Blackjack 97.33% Match the Dealer (8 Decks)
99.53% Blackjack Pro (single Deck) 97.31% Straight 8´s (6 Decks)
99.51% Atlantic City Blackjack 97.22% 21+3 (6 Decks)
99.50% Lucky 7 Blackjack 95.11% Lucky 7s (8 Decks)
99.42% Blackjack Peak 95.05% 6 in 1 (6 Decks)
99.41% Live BJ (Evolution Gaming) 95.01% Perfect Pair (8 Decks)
99.30% European Blackjack 93.34% Royal Match (6 Decks)

One of the best offerings with regards to payout rates is Blackjack Switch, with a theoretical return to player of a massive 99.87%. On top of this favourable figure, it is also one of the most interesting and engaging of variants.

Keep these numbers in mind when you browse, and you’ll know that something smells fishy if you see an online blackjack game with an unusually high house edge. The exception to this is only the side bets, which generally have a lower RTP of around 90 – 95%.

Simply having side bets present usually gets factored into the overall RTP, or they will be marked separately. In any case, it is advisable to avoid placing side bets. The theoretical return of each variant can usually be found in the rules section of each individual game.

Blackjack Tips

Have you ever wondered when you should take insurance against dealers blackjack? Or which blackjack rule variations are in your favour – and what rule variations that are not? Find out now – read on below.

Insurance Tip

The Insurance option in blackjack is really just a side bet that the dealer with an Ace showing has a 10 in the hole. With normal card distribution, at the 2 to 1 payoff, the insurance bet is about 8% against you. In other words – it’s not a good bet at all.

Not All Blackjack Games Are Created Equal

Compared to a single deck game, a two-deck game handicaps your play -0.35%, four decks handicaps you, -0.48%, six decks, -0.54% and eight decks -0.58%. As you can see, it is always to your advantage to play on a blackjack game that offers the fewest decks of cards.

You should also note, the house edge goes up substantially when you go from one deck to two, but the change is less dramatic as you add more decks.

Play With A Clear Head

When you feel tired, it’s time to call it quits – or at least take a break and rest for an hour or two. Always remember that drinking and gambling do not mix. Only bet what you can afford to lose. Rent, car payments and other day-to-day expenses have no place in a casino – be it online or land-based.

Know All The Rules

Too many players don’t even consider the rules before they sit down and play. If you don’t know the blackjack rules or any of the blackjack playing strategies, learn the game on a free demo blackjack machine – or use the free blackjack trainer found right here at online-Casinos.com. A real money blackjack game should not be your classroom.

Advantages of Online Blackjack Casinos

Playing blackjack online offers several factors which trump playing at a land-based casino. In the following section, I’ll go over the most glaring and beneficial of these factors, so as to not to leave any information gaps for when you’re deciding whether online blackjack gambling is really the right shout for you.

Conclusion: Play Blackjack at the Top Casinos

In terms of the sheer volume of games, you can spot some heavy hitters in the top six selection above. On the other hand, the casinos with a smaller selection of games provide some unique and interesting variants.

These sites also offer generous bonuses with favourable conditions, and that’s why these appear in the list as well. Additionally, players who are after low stakes will find the perfect spot within this selection as well.

Playing blackjack online is simple at any of my top operators, with the added benefit of bonuses and promotions to boot!

Frequently Asked Questions About Blackjack

If you have any questions about the game at hand, online casinos or any other related topics, you can send me an email to contact@online-casinos.com and I will respond as soon as possible, or add your inquiry to the following frequently asked questions.

How do I play blackjack?

The aim of blackjack is to have a better hand than the dealer, with the best possible card total being 21. For the full rules and a step-by-step guide, check out this rules article.

Is it better to play online or offline blackjack?

The is largely down to personal preference, however, there are certainly plenty of advantages to playing the online game. For instance, you can practice as much as you want, you can play in private or in groups, you don't have to feel any societal pressure to the tip the dealer and there are a lot more variants available with different side bets for those who play online.

Is online blackjack popular?

Online blackjack has become really popular in recent years as it is really easy to learn and play. The objective of the game is to beat the dealer by getting as close to 21 as possible or by not going bust. This gives the game that widespread appeal as literally anyone can learn how to play.

Can you play online blackjack against other people?

There is a common misconception with the online game that you can compete against other players. You can absolutely join tables with other players but you will always be competing only with the dealer. A few variants with different rules do exist where you can also compete with other players but these are very rare.
