Blackjack basics

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.

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 totaling 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 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.

Mobile blackjack sites

Fancy playing blackjack games while on the go? Thanks to mobile casinos, you can play blackjack anytime, anywhere- even with live dealer games. You still get the same quality as if you’re playing on desktop, too. The top casino software developers build their games with HTML5 technology, so they run smoothly on all devices.
You can play mobile blackjack via a mobile web browser, but the best online blackjack sites also have native mobile apps which are free to download on iPhone and Android. Mobile casino apps store data locally on your device, rather than relying on web servers, which can make for smoother, faster and more convenient gaming. You can also enable push notifications so that you’re alerted to all the latest bonus deals and promotions.

Free blackjack games

Want to play blackjack for free? The UK’s best online casinos all offer a selection of free blackjack games. These free games are ideal if you’re a beginner looking to learn the rules of the game, if you want to work on your strategy, or if you just want to play blackjack for fun. It goes without saying that you can’t win any real money playing free demos, but they’re a great option for those who don’t have the budget to play real money games. If you want to play free blackjack online, all you have to do is create an online casino account and you’re good to go- no deposit required.
Unfortunately, you can’t play live dealer blackjack games for free- these games have much higher running costs than RNG titles, which means they’re reserved for real money players.

Best blackjack software developers

A range of casino software developers 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 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.

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.

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

Customer service

Frequently Asked Questions

  • Is online blackjack fair?

    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.

  • Can I use bonus funds to play live dealer blackjack?

    At some sites, yes. While certain online blackjack sites may restrict the welcome bonus to RNG games, others 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.

  • Can I guarantee a win in online blackjack?

    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, regardless of how good your strategy is.

  • How can I find out the payout rate of online blackjack games?

    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.

  • How can I withdraw my blackjack winnings?

    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.

  • Should I wager on side bets in online blackjack?

    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.

  • Can I play other casino games at blackjack sites?

    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 site, without having to sign up to multiple casino accounts.
