Online casino features are constantly changing. For example, a new bonus may be better or worse. Based on this, we update our casino list to reflect any significant improvements and shortcomings at each casino. Also, when our users sign up and deposit at a casino on our list, we see that as a strong positive signal and boost that casino's rating accordingly.

Key takeaways

  • Legal and Popular: Online blackjack is legal and widely available in the UK, with every casino offering at least one version.
  • Understanding the Game: The goal is to beat the dealer's hand without exceeding 21. Players can win by having a higher hand than the dealer, the dealer busting, or getting a natural blackjack.
  • Basic Strategy: Knowing when to hit, stand, double down, split, or surrender is crucial for success.
  • Card Values: Cards 2-10 are worth their face value, face cards are worth 10, and Aces can be 1 or 11.
  • Payouts: Natural blackjack typically pays 3:2, while other wins pay 1:1.
  • House Edge: With optimal play, the house edge in blackjack can be as low as 0.5%.
  • Insurance Bet: Offered when the dealer's upcard is an Ace, paying 2:1 if the dealer has blackjack.
  • Deck Variations: Single-deck games offer a lower house edge but are less common online.
  • Live vs. RNG Blackjack: Live dealer games provide a more authentic experience, while RNG games offer convenience and speed.

It's perfectly legal to play online blackjack games in the UK. So, as long as you are over 18 and can make a deposit, you're good to go. That said, we recommend playing only at sites licensed by the UK Gambling Commission (UKGC). The UKGC ensures that the best online casinos operate by the book and have robust responsible gambling practices in place.

Rules and Strategy for Online Blackjack

To win at online blackjack, you'll need to understand the rules and basic blackjack strategy. Here, we will cover all of that and much more. We'll also cover card values, insurance bets, and the pros and cons of single-deck and multi-deck blackjack games.

The objectives of Blackjack

The game aims to score more than the dealer's hand without going bust. The maximum permissible score before going bust is 21 – otherwise known as blackjack!

The 3 ways in which you can beat the Dealer

The 2 ways in which you can lose to the Dealer

The conditions for a draw or standoff in Blackjack

All bets are returned if you and the dealer have the same score or both score 21. This draw is known as a standoff. The game round resets as if it never happened.

Blackjack Card Values

All cards in blackjack games are assigned a value. This enables both the player and the dealer to calculate the value of their hand. Here, we cover the available cards and their values:

To score a perfect or natural blackjack, then, a player or dealer must receive an Ace (valued at 11 in this instance) and either a 10, Jack, Queen or King. This gives a combined score of 21.

Blackjack Rules Explained

Firstly, you are only ever playing against the dealer. Any other player at the table is also only playing against the dealer. Therefore, players are never competing against each other. So, you can mostly ignore the other hands. Let's look at each element of the game…

Place Your Bet

The first thing you do at the start of each round is to place your initial bet. Note the minimum and maximum bets for each table. In online blackjack, these should appear somewhere in the interface. Let's say you place a £5 bet this time.

Your £5 is your wager for that game round only. So, if you win, you will get your initial stake back and any winnings. But if you lose the game round, the dealer removes your initial bet from the table. The casino keeps your bet.

The First Deal

After each player has made an initial bet, the cards are dealt. The dealer deals clockwise, with each player receiving a face-up card. The player (always last in the chain) receives a face-down card. Then a second card is dealt to everyone – all cards, including the dealer's, are face up.

This way, you can calculate your score (the card values are listed above). However, you can't tell what the dealer has at this stage. This is what makes blackjack games exciting. We'll cover more on this, what moves you could (or should) make and the basic blackjack strategy below.

Note that if you have an Ace and a 10-scoring card, you (usually) win immediately! That's because you've scored 21 – blackjack! This pays out at 3:2 at most tables – i.e., 1.5x your initial bet. We say "usually" because if the dealer also scores 21, it's a draw (see above).

Hit or Stand?

If neither you nor the dealer wins the round with the first two cards, you can decide whether to hit or stand. For the dealer, the game's rules usually determine this. But for the player, it's entirely up to you. Choosing to hit or stand depends on the cards in play.

If the dealer's face-up card is a good one, scoring 10 or even when the dealer has an ace, you might want to hit. However, it depends on your hand. So, if your score is, say, 20, then standing is the apparent option. If your score is around 16 or 17, it's a judgment call.

Most online blackjack games allow players to make five different decisions at this point. So, you can choose to hit, stand, double down, split a pair or surrender. Let's review each one before moving on to the blackjack card values and the best tactics…

Classic Blackjack moves

The dealer's moves are predetermined. So, they will automatically stand if the dealer scores 17 or more (without going bust). However, if the dealer scores 16 or fewer with their initial hand, they will automatically hit even if it's more likely they will bust.

You might also hear that surrender is called late surrender. This is technically true and shows how long blackjack players have been around. There used to be an early surrender option, too; however, casinos removed it decades ago because it aided card counters.

Online Blackjack Payouts

Players get payouts on three different outcomes. Each one depends on the player remaining in the game – i.e., not going bust. So, here's what happens when you beat the dealer:

Basic Blackjack Strategy

Let's discuss how to win at online blackjack. First, temper your expectations. Don't expect to always win – there's a house edge in every round (see below). Also, don't focus only on the cards you have been dealt. The dealer's face-up card is essential, too.

Should I Surrender?

This is the first question to ask yourself each round. You can only surrender after being dealt your first two cards, never after hitting. If you cannot surrender under the game rules, or you feel you shouldn't surrender with your current hand, move on…

Can I Split?

If you have a pair, you can split and play with two hands (so long as you pony up another wager equal to your first). The same is true if you have two cards with the same value, like a Jack and a King. If a split is not on or you don't feel like splitting a pair, move on…

Should I Double down?

Consider doubling down if you're confident your hand is better than the dealer's. Some blackjack games do not allow doubling down on certain hands – be sure to check this. But if it's possible and you have a reasonably strong hand, go for it. Otherwise…

Hit or Stand?

In simple terms, you should follow what the dealer has to do – this is based on the probability of what's likely to come up next. So, if you score 16 or fewer, you should probably choose to hit, mathematically speaking. But if you have 17 or more, you should probably stand.

Blackjack House Edge

When played optimally, the blackjack house edge is 0.5%. That is incredibly low! However, the house (AKA the casino) always has the advantage of going after the player. For example, the player will always bust first, even if the dealer eventually busts. And when that happens, the player loses their money, even though it's technically a draw. This explains the house edge.

What is an Insurance Bet?

One last thing that we didn't cover above. Insurance bets are built into most blackjack games. So, when playing blackjack online, you'll see an area for insurance bets in the window. The most basic form of blackjack insurance is when the dealer has an Ace…

After your first two cards have been dealt and you've seen the dealer's face-up card, you'll be offered insurance. You can put down an amount equal to up to half your bet. Therefore, this side bet is not recommended for beginners who are still learning.

Essentially, you can buy insurance against the dealer having a 10-value hole card. Therefore, you make insurance bets before hitting or standing. This pays 2:1 if the dealer draws a natural blackjack after the hole card is revealed.

Single-deck Blackjack or Multi-deck games?

You will most likely use a shoe containing six to eight decks when playing blackjack games in London, Las Vegas or Monte Carlo. That's because counting cards is much easier if only one deck is in play. Blackjack tournaments will also use six to eight decks.

While single-deck blackjack is increasingly complex to find in traditional casinos, certain game providers offer it online. And best of all, it can lower the house edge to an astonishingly low 0.15%. However, other rules can be tweaked to reduce a player's advantage.

Online Blackjack vs. Live Dealer Blackjack games

While plenty of blackjack variants are available online, none are quite as distinct as video blackjack versus live blackjack. Video blackjack games are more like computer games, while live dealer blackjack games offer an authentic casino experience.

In live casino blackjack, HD cameras show you all the action in exquisite detail. There is often more than one angle, too, zooming in on key moments in a round. Plus, players can interact with the dealer via live chat and hear calls over headphones or speakers.

Live casino games from Evolution and others offer nearly enough of the same casino experience as in Las Vegas. Plus, plenty of blackjack variants are available. For example, check out Speed Blackjack, Infinite Blackjack, and Blackjack Switch.

How to Improve Your Blackjack Strategy

When starting out, playing free blackjack games is the way to go. You won't be able to play live blackjack in such a manner – there's only enough room for those making wagers. But it's not too hard to find a video blackjack game or an app that lets you play with zero-value or free chips.

Play as many rounds as possible once you've found a free blackjack game. This way, you can build your confidence and see how various situations play out. Refer to our guidelines above for help with tricky situations.

From there, you can download a blackjack chart that shows you the optimal move each time. The house edge is lowest when played this way. Then, once you're up to speed, you can play an online blackjack game for real money. We wish you good luck!

Can I Play Blackjack Online as a Beginner?

Of all the card games available at the casino, classic blackjack is one of the easiest to pick up. Compared to poker and other casino games, basic blackjack strategy is a relative walk in the park.

Follow our guidelines above to learn how to play blackjack online. We've also provided plenty of online blackjack tips that you can try in an online blackjack simulator or free app. This way, you lucky ladies and gents can get a leg up in online blackjack.

Also, if you're unsure how to get started, focus on hitting or standing. Play blackjack online for free to get your bearings and decide whether to stand or hit each time. You'll soon see how your choices affect you. You'll bust a few times, but you'll win some too.

Card Counting and the Blackjack House Edge

In many ways, blackjack is one of the most famous card games because players try to take down the house. So much so that, for many people, blackjack is almost synonymous with card counting nowadays. But while it's technically not cheating, it will get you kicked out.

Some form of card counting appears in many guides, from basic strategy to elite multi-player battle plans to casino blackjack. And it's not all that difficult to understand – but implementing it in the heat of the moment takes practice. So, let's explore the topic…

Famous Blackjack Card Counters, Cheats and Swindlers

The most famous card counters were the MIT Blackjack Team. Mainly run by Harvard student Bill Kaplan for many, many years, the team trained players to use a system to beat blackjack casinos. The team then sent three players to casinos in Nevada, Atlantic City, and other places.

One player was a spotter who kept a running count. A second player placed small bets and wasted money while verifying the spotter's count. When the deck went positive, the controller signalled the big player, who bet big and won more often than not.

The team's exploits were captured in Ben Mezrich's book Bringing Down the House. The subtitle says it all: The Inside Story of Six MIT Students Who Took Vegas for Millions. The book also inspired the 2008 movie 21.

How Does Card Counting Work in Blackjack?

While counting cards seems complicated, the basic premise is easy to learn. Players do not memorise every card that goes through the shoe. Instead, they assign a value to each one and keep a running count. This determines when the cards in the shoe are positive or negative.

So, whenever a 2-6 appears, a player adds one to the running count. For 7-9, he does nothing – the value is zero. And when a 10-Ace appears, he takes away one. If the running count increases, the deck favours the player. When negative, it favours the house or casino.

This works well with single-deck games. But with multiple decks, the running count only starts to tell nearer the end of the shoe. So, to get an accurate count, a player divides the running count by the number of decks remaining. And that's essentially the gist of it!

Does Card Counting Lower the House Edge?

Counting cards does give professional and elite gamblers an advantage. So, even though it's not illegal, casinos will not let the behaviour continue. That's why players will be removed from the premises – or kicked out when card counters play blackjack online.

Card counters can turn the house edge on its head when they play blackjack in Vegas or Atlantic City. In this way, the player has the edge. It's usually not much, but enough to turn the tables. That's why blackjack is the card game for professional counters.

How Do Casinos Prevent Players from Counting Cards?

Many wonder, "How do online casinos protect themselves from blackjack card counting?" The answer is simple: sophisticated algorithms analyse player moves over each round. With AI and analysis of thousands of games, clear patterns emerge.

If something gets flagged in a traditional casino, the pitboss will come over to keep an eye. They may also send an attractive bartender to distract the player. Or they may do an early reshuffle to ruin the count. If it continues, the casino will remove and ban the player.

Using some of the tactics above is a little more challenging online. However, players suspected of card counting in live dealer games will receive a warning. They will be suspended and kicked from the site if they continue to employ counting tactics.

Do Online Casinos Cheat in Blackjack Games?

In the Wild West, casinos employed numerous ruses and scams. However, cheating the player was unnecessary. The house always had the edge without card counting, and gaming regulators were already very hot on cheating casinos.

We only recommend playing at blackjack sites licensed by the UK Gambling Commission (UKGC). The UKGC ensures that independent testing organisations like eCOGRA test all blackjack games. The regulator also ensures responsible gaming to protect vulnerable UK players.

Playing Blackjack at Live Dealer Casinos

As mentioned above, live dealer blackjack is both exciting and engaging. Tables suit all budgets, too. There's something for everyone, from classic blackjack to Salon Privé and VIP tables. Most live casino blackjack games use the same rules, making them easy to pick up.

Some variations include additional side bets, making the action slightly more intense. However, many of these side bets increase the casino's advantage over the player. So be sure to research the implications.

As for recommended live blackjack companies, there are almost too many to mention. But check out the blackjack rosters of Evolution Gaming, Ezugi, NetEnt Live, Playtech and Authentic Gaming. In short, you'll never be short of live blackjack options.

What Blackjack Bonuses Can I Get at UK Online Casinos?

While blackjack-specific casino bonuses are rare, most sites let players use their bonus funds on blackjack games. This includes the top welcome bonuses recommended by GamblingAuthority. However, free spins are strictly locked to slot games.

You can use live casino game bonuses on live dealer blackjack titles. Just note that blackjack wagering contributions are often much lower than those for slots. We're talking around 5% instead of the usual 100% contribution of slots.

Playing Online Blackjack on Your Mobile or Tablet

Playing blackjack online via a phone or tablet is possible and often preferable. All modern casino games are built or optimised for iOS and Android touchscreen devices. Tapping, dragging, and other touchscreen gestures translate well to blackjack moves.

You may be tempted to download one of the many blackjack apps on the App Store and Play Store. However, many are poorly made and often don't let you play for real money. Therefore, playing blackjack at a mobile online casino or via its dedicated app is always best.

A Brief History of Blackjack and Vingt-et-un

Blackjack was formerly known as Black Jack or Vingt-et-Un (French for twenty-one). The game we now know as blackjack is thought to have originated in Spain. Spanish writer Miguel de Cervantes references characters cheating at veintiuna (Spanish for twenty-one).

The first recorded blackjack game in Britain was in the 1770s-80s. Rules for a game called Vignt-Un began appearing in 1800. The game is thought to have spread from Europe to America shortly thereafter, and a reprint of the English rules appeared sometime in 1825.

A French card historian named Thierry Depaulis claims to have proved that unknown American gold prospectors renamed the Vingt-et-un game to blackjack in the late 19th Century. Since then, the card game has spread worldwide—and the rest, as they say, is history.

Online Blackjack FAQ

We don't know of many online casinos that don't feature blackjack in one form or another. But if you want to play live dealer versions of the game, check out the available titles before you sign up. You can find info on the games in each of our expert online casino reviews.

Since the UKGC tightened rules on free casino games in the UK, players must sign up for an account before playing free games. This prevents those under 18 from playing online blackjack. Many free games are also available in the App Store.

Yes, of course. Otherwise, no one would want to play it. Just follow the links to the reputable online casinos listed on this page. This will take you to the sign-up page where you can open a new account, make a deposit and start playing blackjack.

As long as you're over 18 and a resident of the United Kingdom, you won't have trouble finding and playing blackjack for real money. Just play only at UKGC-licensed online casinos, and research the sites on your shortlist before signing up.

Fun? We (and millions of others) certainly think so! And yes, learning to play blackjack shouldn't take more than a few hours. Plus, with all the tips and tricks we've provided above, you'll be a dab hand in no time. Then, you can experience the game for yourself.

If you want to win real money, you'll likely need to make a deposit. However, if you just want to play the game for fun, those options exist at UK online casinos too. You might just prefer to win money eventually. At least online casinos let you play both types of games.
