Online Blackjack

Blackjack: one of the world’s most renowned and iconic casino games. Played in many land-based casinos, this classic card game is brought to your screens in numerous forms. Blackjack is wildly popular, and 21.co.uk brings you a range of different games to suit any style, with various special features, side bets and HD display. What do they all have in common? They all offer an epic and authentic blackjack experience, whether you’re playing on desktop, mobile or tablet.

Here at 21.co.uk, we believe in variety, and that’s exactly what we’ve delivered with our range of virtual and online blackjack games. Put your skills and knowledge of the game to the test, whether it's against a real or virtual dealer.

There’s only one question left: which one will you play?

About Playing Blackjack Online

Before we dive into our impressive collection of blackjack games, let's familiarise ourselves with what it is and how it works. Playing blackjack online is very similar to blackjack in a real-life casino, and you'll find that the majority of our tables follow the same rule set as land-based blackjack games. The objective is very much the same - obtain a hand which is higher than the dealer’s without exceeding the total of 21, also known as going 'bust' - if this happens, you lose the game. You'll be dealt two initial cards, whether these be virtual or real, and will then be given the option to hit, stand or double down. All of our games are very user-friendly, with an easy-to-navigate game interface and clearly marked buttons. If you want to know more about a particular table then check out the game information page which will provide a good idea of what to expect. If you’re looking for an in-depth experts guide to online Blackjack, click the link below.

Now that you understand the basics, it is time to learn to play. Login and sit down at your virtual blackjack table. Wager by clicking on the chips underneath the video screen. When you are ready to go, click the 'Deal' button to see your first two cards. You can then:

Hit – Take another card

Stand – Take no more cards and defer to the dealer

Double – Double your wager and then take another card

Split – Split your two cards into separate hands and draw two more cards (note that this automatically doubles your wager).

A couple of things to note here. First, you can only split on the first draw when dealt with a matching pair. Once you decide to hit or stand, your opportunity to split has passed. Second, note that our Live Blackjack game requires the dealer to stand at 17. This gives you a slight advantage if you are willing to take the risk on a card total of 10 or more. At the conclusion of each hand, you can either repeat the next hand with the same wager or choose a new wager. Click the 'Clear' button to remove all wagers from the table and start over.

About Blackjack Strategies

Basic Blackjack Strategy was first developed by a mathematician who used a computer simulation to play hundreds of millions of blackjack hands. By playing the hands, analysing the results, and running mathematical equations, the computer was able to come up with a basic set of rules for improving player advantage. For example, the basic strategy says a player should always split aces but never 10s. It dictates a player should always hit with a hard total of 8, regardless of the dealer's up card.

For players looking to brush up on their blackjack skills, or people new to the game our comprehensive guide on How to Play Blackjack has everything you need to get the ball rolling.

Check the most frequently asked questions relating to playing blackjack online below, from odds to legalities, from simulated to live products. We’re giving you some answers, so you can get the best out of your online casino experience.

Can I Play Real Money Blackjack Online on 21.co.uk App?

Our mobile casino app is available across Google Play and Apple stores for you to download in seconds. The ease, quickness and personalised experience, which is present in our mobile apps are what makes them stand out, as well as not having to play through a traditional browser. Simply clicking in the app and being able to play in seconds is a feature our returning players enjoy as they are a click away from all their favourite titles. Additionally, our mobile casino apps have been launched with functionality in mind ensuring your experience is even more smooth and intuitive compared to a browser, unlike others on the market.

Are blackjack winnings subject to taxes?

No. Prior to 2001, UK gamers were subject to a betting duty applied to all their winnings. That duty was abolished. Now your blackjack winnings are completely tax-free, as are winnings from all sorts of gambling endeavours. Furthermore, there is no requirement to report winnings from gambling to HMRC.

Can I play blackjack for free?

Yes. You can play demo versions of our blackjack games, and most other games on our site, for free when logged into your 21.co.uk account. You must, however, complete our verification checks in order to access demo games. Demo mode lets you try the game out to see how it works and decide if you enjoy playing before you bet with any real money. The only exception is Live Blackjack, as this is played in real-time. New players can also claim £10 free, so you can try out a few games on us.

What is the difference between live blackjack and a simulation?

Where live blackjack is played with a real dealer standing behind a real table, a simulation is essentially a piece of software that provides all of the same functionality without using an actual dealer or table. The rules are exactly the same.

Can I play blackjack on a mobile device?

Yes, absolutely. Mobility is one of the key features of modern online games that we are happy to provide players. You can play blackjack anywhere you have an internet connection.

Is blackjack always played against the house?

Yes. In some online games, there are multiple table positions allowing for multiple players simultaneously. However, players never compete against each other. Blackjack is always played exclusively against the house. However, this doesn’t mean you can have some healthy competition with your fellow players!

Is there a winning strategy I can employ?

Numerous blackjack ‘experts’ have come up with their own strategies for playing blackjack. It is fine to try any of the strategies you find intriguing, but no blackjack strategy can guarantee 100% success. We cover this in more detail in our blackjack strategy guide.

How many decks are normally used in online blackjack?

The number of decks an online casino uses varies from one to the next. On average, it tends to be around six. However, some casinos use eight while others use four. There is no way to know for sure.

Do online casinos shuffle after each hand?

Regularly shuffling the deck is something the online casino will often do to make it harder for players to count cards. Interestingly enough, statistics have shown that card counting is a fruitless strategy when playing blackjack online, but many pro players such as Bryce Carlson claim otherwise.

What kind of blackjack games can I play online?

Here at 21.co.uk, we pride ourselves on offering the best of the best to our players. Our tables are no exception. Whether you like the immersive experience of Live Blackjack or the extra side bets offered by Blackjack Perfect Pairs, there’s something to suit any style of player. We offer games created by some of the biggest names in the industry, such as NetEnt and Evolution gaming. High rollers may enjoy our selection of premium VIP Live Blackjack games, which offer higher betting limits and other great perks.

What are the odds of winning a game of online blackjack?

The odds can vary from game to game, but in most instances, a blackjack pays 3:2. If your hand exceeds the dealer’s (without going bust) then you’ll receive 1:1 odds. If you choose to place side bets, the odds will vary depending on which bet you place, but will usually be higher than a standard blackjack bet.

Do the same rules apply in online blackjack games as in land-based casinos?

Online and live blackjack games will always follow the same set of basic rules that you’d play by in a land-based casino. Although some games may offer some extra features, the overall concept remains the same.

What is the highest betting limit for online blackjack?

The maximum bet that you can place in varies from game to game. For example, Blackjack Perfect Pairs allows you to bet £1000 per round, whilst Classic Blackjack Gold only allows you to stake £200. VIP Live Blackjack offers higher betting limits to satisfy players with bigger bankrolls.

How does online blackjack work?

Simulated blackjack games work in a similar way to online slots and other online casino games. A piece of software called a Random Number Generator produces an outcome to each round. The cards dealt to you, the dealer and other players are therefore chosen at random by this technology, ensuring a fair game. Much like real-life blackjack, you’ll take a place at the blackjack table and place your bet by selecting chips, which will appear in the betting box in front of you.

Here at 21.co.uk, we have a number of fantastic slot and casino game providers but only a special few have created games for our Live Casino. Our most prominent provider is Evolution Casino Gaming who are the largest Live Casino provider in the world and are responsible for some of the greatest games in the industry.
