How We Rank the Best Blackjack Casinos

There are several factors we take into consideration when ranking the best blackjack casinos in the UK. The most important aspects we research when we look at casinos for online blackjack are:
Casino bonus


In order for a casino to be on the list above, they must have obtained a license from the UK gambling commission. This is because having an operator license ensures that a casino is safe to use, has been inspected heavily, is regulated by an external agency and adheres to rules.
Udbud av spil

Game Selection

The amount of variations and types of blackjack that a casino hosts is critical. The more options they have, the higher they will rank on our list. This is because players that sign up to and play at an online casino want as big a choice as possible when it comes to what games they can play. There’s no point using a casino with very few blackjack games.
Live casino


The highest rated blackjack casinos in the UK have top quality security systems in place not just for blackjack, but across their whole site. This means that players will be able to relax and have peace of mind that their date and personal information is safe on the site they use.
Live casino


Our rankings are so accurate because we take into consideration the reviews and opinions of current players at each casino. This is a great indicator of whether or not a casino is worth using.

Live Casino

Casinos that have the ability to host live dealer blackjack games get much higher ratings from players as many prefer having a real person who is in charge of the game and dealing the cards.

Mobile App

The best online casinos have blackjack games that can be played on mobile as well as their site. These mobile apps should be quick and smooth running in order to give players a great blackjack experience.

Terms and Conditions

It’s important that the terms and conditions you agree to when playing online blackjack are easy to understand and the casino you’re using doesn’t try and catch players out by putting in sneaky terms.

Payment Methods

Whether you want to deposit money and start playing blackjack as soon as possible or withdraw any winnings you make, there should be plenty of payment methods available for players to do this.

Customer Service

At some point in the future, it’s highly likely you will encounter a situation where you need to get in contact with the customer support team at an online casino you’re using. The best casino sites have a helpful, friendly and fast acting team that can provide you with assistance 24/7.

Blackjack Explained

You will need to get a higher total value of cards than the dealer in order to win a game of blackjack. You will be dealt two cards to begin with and from here you can either hit, stand, double down or split depending on the value of them. You will be able to see one of the dealer's cards when you make this decision. The dealer must stand on 17 and must hit on anything below this.  If you go over 21, then you will bust and automatically lose the hand. If the dealer goes over 21 and you’re still in the game, you will win due to them going bust.

Is Blackjack Legal in the UK?

Yes, blackjack is legal throughout the entire UK. This goes for both in-person and online iterations of the game. This means that you can play blackjack at any of the hundreds of licensed online casinos in the UK and take advantage of the numerous benefits that online blackjack provides.

Types of Blackjack

There are tons of online blackjack variations to choose from. Sometimes it can feel like an endless choice. Here are the most popular forms of the game at casino sites across the UK.

Double Attack - After the dealer’s upcard is shown, players can double their stake. 

Double Exposure - This shows players both of the dealers hands at the start of a game.

Multihand - Allows players to receive more than one hand in a game. 

Progressive - All blackjack games contribute towards a side bet that has a jackpot. Winning criteria depends on the site you’re using but usually you need to get three or four aces in a hand to win the full jackpot.

Spanish 21 - Players win instead of pushing if both themselves and the dealer gets 21. Also there are no tens in the deck and players can double down whenever they like.

Surrender - Players can give their hand up after seeing their first two cards. If they surrender they will only get 50% of the initial bet back.

Switch - Allows players to get two hands and then swap the top two cards between hands.

Live Casino Blackjack

When you use an online casino, you will have the option to play blackjack against the computer or a real life dealer. The latter is part of the live casino section of a website or app and it is extremely popular due to how close it is to the experience of an in person blackjack game. The rules and mechanisms of live blackjack at an online casino is exactly the same as if you were using a land based casino. The benefits of this particular type of blackjack is that you get to quickly access the best tables with complete anonymity and you can also use welcome bonuses on these games.

Ultimate Blacjack Glossary

When you start playing blackjack, you’ll see a lot of jargon on your screen or hear it from the dealer's mouth if you’re using a live casino. Here are the most important words to understand when you play along with their meaning.

    • Bankroll - How much money to have available to use for wagers.
    • Bust - Having a total of more than 21.
    • Double Down - This allows you to double your bet and receive only one more card. This is usually done when a player gets an initial value of 11.
    • Hit - An action you can during the course of a game. This will add another card to your original 2 cards.
    • Hole Card - The name of the dealer's card that is face down. This won’t be revealed until the very end of the game.
    • House Edge - The odds of the casino winning over the player at any given game.
    • Insurance - If the dealer shows an ace, you can choose to take out insurance, which will pay 2:1 if the dealer has blackjack. The value of this insurance bet can be up to half of the original bet. If the dealer doesn’t get blackjack, then you will lose the money you placed as insurance.
    • Natural - When the first two cards add up to 21.
    • Push - When you and the dealer end up having the same total. You will receive the money you bet back.
    • Split - If your first two cards are the same value, you can play each of them as a separate game with the bet of each game being the same as the initial bet you placed. People usually do this when they get two tens as a strategy to try and get 21 on their hands.
    • Stand - When you don’t want to add anymore cards to your pile.
    • Surrender - Some variations allow you to abandon your hand and recover half of your initial bet after seeing your first two cards.
    • Upcard - The name of the dealer’s card that is showing.

    Blackjack Card Values

    There are a total of 13 different card values across all forms of blackjack. Before you start playing, it's important to know the meanings of these cards are. They can be split into three different categories:

    Ace (A) - This can have a value of either 1 or 11 depending on the other cards in the hand. This is the only card in the deck that can have more than one value.

    Faces (J, Q & K) - All of these face cards have a value of 10.

    Numbers (2, 3, 4, 5, 6, 7, 8, 9 & 10) - Each of these cards has the value of the number shown on the card.

    Blackjack Cards

    Blackjack Strategies

    Implementing a well developed strategy when you play blackjack is a great way to try and lower the house edge and this will give you a higher likelihood of winning games at the table. Here are the top five blackjack strategies to use.

    Don't Split Fives or Tens

     If you have fives or tens, you will want to hold onto these cards in the form of one hand. The tens should not be split because you would have a total value of 20 which means you’re extremely likely to win the hand. However, if you split the tens you have a chance of getting lower hands such as 16. The reason you should not split fives is because you have a total value of ten. This means that you can hit and receive another card without the risk of going bust. There are several face cards you can now get that will take you to either 20 or 21. This would then subsequently most likely win you the game.

    Split Eights and Aces

    Splitting eights and aces is a great strategy. This is because hitting on 16 (two eights) can always be risky as it leaves you with little wiggle room to not get busted. Splitting aces means that you open yourself up to a high chance of getting one or two blackjacks while receiving much more money. You will receive more money if you win because by splitting you are effectively doubling your initial wager. Additionally, blackjack pays out a total of 150% of your initial bet and this is much better than receiving 100% back if you win by not splitting aces.

    Don't Take Insurance

    When the dealer’s upcard is an ace, you will be given the option to take insurance in the event that they get blackjack. This insurance is technically a bet that is half your initial bet on the dealer getting blackjack. This means if the dealer gets blackjack you will at least get something back. However, despite the temptation the best choice is to not take this insurance as they are more likely to not get blackjack than to get it, even with an ace as their first card.

    Standing on Low Teens Can Work

    If you have a 13, 14 or 15 and the dealer’s upcard is between 2 and 6 then standing is a good strategy. This is because the dealer must hit and receive another card if they are on less than 17. This means that if their hole card is a face card, 10 or 9 not only will they have to hit but they also will have a high chance of going bust. Therefore, although it’s daunting sometimes it’s better to be safe than sorry with your blackjack strategy depending on the circumstance.

    Double Down on 11

    We recommend always to double your bet if your first two cards have a total value of 11. This is because you can’t go bust if you hit for an extra card and it allows you to get a very high total value while doubling your winnings! If you ever want to double your bet, there is no better number than 11 to do this.

    Blackjack Game Outcomes

    When you play blackjack, the outcome of your game will be one of eight different possibilities. Usually, this will be a standard win or loss. However, now and again you will encounter a more unusual way of winning or losing. We’ve laid out exactly what these ways are and what the payout and loss for each one is.

    • If you win - You will double your money and receive 2x of your bet back. This is the second most likely occurrence to happen in a blackjack game.
    • If you win with blackjack - You will receive 1.5x of your initial bet back. This is because blackjack pays odds of 3:2.
    • If you win a double down - You will receive 4x of your initial bet back. This is due to the fact that you will have doubled your bet. For example, your starting bet is $10 but then you double it to $20. If you win, you will receive $40 which is 4x of your original wager.
    • If you win one split - You will break even and not get any profit or loss. 
    • If you win both splits - You will receive 4x of your initial bet back. This is because by splitting you have technically doubled your initial bet, so the same logic applies in terms of receiving 4x of your original bet.
    • If you lose - You will lose all of your bet. This is a very common occurrence in blackjack hands.
    • If you lose with insurance - You will break even and not get any profit or loss. This is because if you take insurance and the dealer gets blackjack, you will receive your initial bet back.
    • If you lose a double down - You will lose 2x of your bet. For example, if you bet $10 and then double it to $20 and lose, you would have lost twice your original bet.
    • If you lose both splits - You will lose 2x of your bet. This is because it’s the same value as doubling down.

    Advantages of Online Blackjack

    • Bonuses - The endless string of blackjack bonuses that can be claimed at online casinos in the UK makes it incredibly advantageous compared to in person blackjack. Bonuses such as matched first deposits can be used when you play blackjack, allowing you to play more games and win more money.
    • Selection of Games -  Just like bonuses, there’s a huge variety of blackjack games on casino sites. Some host as many as 10 different variations of the game both through their live casino and digital games hub. This is much more variety than what could be found at real life land based casinos.
    • Privacy - Online blackjack gives players the unique benefit of being able to gamble in private. If you don’t want to bump into anyone or have other people watch you as you play, then online casinos are the perfect place for you to play a whole host of casino games.
    • Accessibility - Casino sites and apps make it incredibly easy to start playing blackjack. Thanks to these platforms, you will be able to play within minutes. This is much more convenient than having to travel to a specific location in order to play blackjack.
    • Practice - Many casinos allow players to try out free demos of their games. This means you can implement everything you learn here into real life practice and build up your experience and knowledge of blackjack. This is a great tool for both newbies to the game and regular players that want to test new strategies.

    How to Play Online Blackjack

    It's incredibly easy to get started playing online blackjack in the UK. Check out these 5 simple steps to get up and running at the best casinos in the country.

    Choose an Online Casino

    In order to play blackjack, the first step is to select the right online casino for you. This should also be a casino that specifically excels in the game you want to play. The list at the top of this page highlights the top 10 casinos in the UK for blackjack players. Select the “Visit Site” button next to your casino of choice, to get started. You will need to sign up if you don’t already have an account.

    Pick a Variation

    Once you’ve signed up or logged in, head over to the blackjack section on the site. This should be easily identifiable due to blackjack being front and centre on most sites thanks to its popularity. Here you will see all the different types of games you can play. Select the game you want to choose and join the table. While each variation will show you the rules of the game, you can learn about the most popular types of blackjack in the previous section of this page.

    Place a Wager

    This can usually be anywhere from £1 to £1,000 depending on the casino you use. Once you’ve placed a wager the game will start and you will be dealt two cards. The total value of these two cards, along with the upcard that the dealer is showing should determine what your next move will be.

    Take Action

    Depending on what your cards are, you will either need to select “hit” in order to receive another card, “double” to double your bet and receive one more card, “stand” to stop getting any more cards or “split” in order to divide your two cards into two separate hands that will then receive a card each. You can find out more about the best blackjack strategies further down this page.


    Once you and the rest of the people on your table have made a decision, the dealer will then flip over their hole card. If the total value of their cards is 16 or less, then they will have to hit and receive another card. If this card makes their total value go above 21 then you will win the hand if you’re still in it due to them going bust. If the total value of their first two cards is between 17 and 21 they will stand. Congratulations, you now know how to play online blackjack!
