How we choose the Best Blackjack Sites 

At Gambling Zone, we select the best blackjack sites after comparing what all the great platforms offer. Our rating system is based on specific variables, including site security, licensing, bonus offerings, and banking options. We also consider each site's gaming variety, customer service, and mobile optimization to find the best option.

After reviewing some of the most popular blackjack sites in the UK, we compared the gaming variety at each casino. We provided details about the highest-ranking blackjack varieties in these online blackjack casinos.

Mobile Friendly Blackjack

Optimization for mobile devices is another crucial factor we used to determine the best blackjack sites in the UK. We understand that users are looking for online casinos with mobile applications or mobile-optimised websites because they allow them to bet on the go and in the most friendly manner. An online casino is optimised for mobile devices when it adjusts perfectly to fit the screen of your smartphones or tablets. All the functions accessible on your desktop or over the web should also be accessible on your mobile device at the same speed.

Fully Licensed

Icon that symbolizes Licenses

During our review, we make sure that only fully licensed casinos make it to the list. We understand that playing blackjack in an unlicensed casino can be risky. Make sure that you only play blackjack in casinos with a UKGC licence. The United Kingdom Gambling Commission is currently the leading gambling regulator in the country. There are blackjack sites that serve many markets globally and may not be licensed by UKGC. For such, you should search for licences from other leading licensing bodies like AGCO for Ontario or the MGA for the rest of the world.

Blackjack Site Security

One of the first things we check is the safety and security of these online blackjack sites. We ensure the sites have encryption to protect user data and robust firewalls to prevent security breaches. At the end of our review, we found that the most secure sites had eCOGRA certifications. Blackjack sites UK with this certification, make customer protection and fair gaming their priorities. eCOGRA also ensures responsible casino conduct.

Blackjack Bonuses & Promotions

Bonuses and promotions with lenient terms and conditions are also top factors we consider because they improve your overall gaming experience. We recommend online casinos that offer lucrative welcome bonuses, VIP programs, and ongoing incentives for all users. Also, we ensure that the terms and conditions of these bonuses are favourable to users. An online blackjack site should not have unrealistic wagering requirements.

Variety of Blackjack Games

Two cards showing a jack and a spade to represent blackjack

We understand that repeated playing of the same blackjack game can be boring, so we only recommend sites that offer variety. Ideally, we recommend sites that provide popular variations such as Lightning Blackjack, Progressive Blackjack, Blackjack Switch, and American Blackjack. The rules of the base game of these different types of blackjack games may be similar, but the features are slightly different.

Customer Support

Customer Support

However good an online casino is, there may be times when you need to clarify an issue. During our research, we contacted customer support using all the options available on each platform. The best platforms offered instant replies through live chats and telephone. Email support also offered quick responses. Apart from quick response times, we also look at if customer support is offered in multiple languages.

Popular Banking Options

A casino should offer a variety of payments for its players. Besides the number of banking options, we also consider the monetary limits, fees, and withdrawal times. The fees vary across banking options but are reasonable.

Best Online Blackjack Sites for Live Blackjack Games

Live dealer games bridge the gap between playing at home and enjoying an immersive gaming experience in a real-life environment. Most blackjack sites offer some live versions of the game. The best ones have lots of titles from leading providers, including both the standard version and some variants. The leading sites also have bonuses you can spend on live blackjack.

Popular Blackjack Games and Variations

With different blackjack variations available online, our experts at Gambling Zone recommend the following games.

European Blackjack

Here, there are two decks of 52 cards each, and it comes with a higher potential risk than traditional blackjack. The payout is at odds of 3:2 and players can only double down when their initial hand value is 9, 10, or 11. If you achieve a blackjack at the same time as the dealer, then your both hands are deemed a push or tie and the initial stake is refunded.

Pontoon

With this blackjack variation, players can win higher payouts. While the dealer exposes one card and hides the other in regular blackjack, the value of both cards is hidden with Pontoon. Also, the best hand in this game is when you secure 21 points, hence the second name, Spanish 21. The average house edge for this game is 0.38%.

American Blackjack

For a good reason, this is one of the most popular blackjack variations in the UK. American blackjack requires a deck of 52 cards and maintains the traditional blackjack rules. Besides, it offers a favourable average house edge of 0.5%, which is impressive since the house edge for classic blackjack can be up to 2%.

Blackjack Switch

The switch variation of blackjack offers more flexibility than any other type on this list. It also is one of the most recent variations. With this game, players create a better hand by switching the first two bets if they have an equal value. Also, the average house edge for Blackjack Switch is 0.58% with an optimal strategy.

Perfect Pairs Blackjack

This blackjack variation is similar to American but has a unique side bet feature. If you predict that the first two cards on the deck will have the same value, you can increase your potential payout with a side bet. The house edge for Perfect Pairs Blackjack ranges from 2% to 11%.

Other Blackjack Live Dealer Games

Blackjack is a classic live dealer game on the best online blackjack sites in the UK. However, there are other interesting live dealer games available. Gambling Zone lists some best live casino sites for games other than blackjack. You will find live games like baccarat, roulette, and poker. Also, there are live game shows, monopoly, and other options.

If you are interested in these live dealer options, check out the best Live Casino Sites on Gambling Zone.

The Benefits of Playing at Online Blackjack Sites

What makes blackjack one of the UK’s most popular table games is that it is not all about luck; there is some skill and strategy to it. This makes the game more enjoyable and the wins feel more rewarding. While the game itself has benefits, playing it online also has a few advantages.

check

Privacy and Security

All websites that offer real money gambling services, including casino sites, should take the safety and security of players seriously. Thankfully, most of them do. They use the latest, state-of-the-art software to ensure that all members have full protection at all times. All the online blackjack sites we promote are trustworthy and reliable; they put the player first and take all the appropriate steps to protect players’ privacy and make sure they are always safe.

check

Bonuses and Offers

The leading online casinos have generous bonuses not just for new players, but for current members too. The purpose of bonuses is to encourage people to join a casino and become a loyal player. The best sites for blackjack have regular promotions that give out bonus money. This is a currency you can spend on blackjack and all other games. It works just like real money, though unlike cash, you cannot withdraw it.

check

Variety of Blackjack Games

Like other casino games, blackjack has multiple variants such as single-deck blackjack and Spanish 21. Each one of these differs from the standard version of the game by offering extra side bets, rule changes or both. The best online blackjack sites have variants in addition to the standard version of the game in order to satisfy players’ tastes and demands. They should also offer live versions of blackjack (again with both the standard version and variants).

check

Free Blackjack Practice

Since blackjack involves decision-making, you will no doubt want to practise before playing the game for real money. Thankfully, free play is widely available online. Just about every online casino that has blackjack games lets you play in demo mode. This is where you play a game as usual, except it does not involve any actual money. You are free to play as much as you like and develop your skills without having to spend a penny.

check

Play Wherever and Whenever You Want

Online casinos allow you to play blackjack and other games whenever and wherever you want. They are open round-the-clock and, thanks to mobile sites and apps, you can play while on the go. No matter what time you feel like playing blackjack, you can log in to your casino account and have a game or two. If you want to play on your mobile, consider downloading a casino app if possible; these are more convenient than mobile sites.

Blackjack Bonuses and Offers

At a typical online casino, there is a range of promotions running at any time. As well as the welcome offer for new players, there should be a number of special offers for current members. Below are summaries of the main bonus types you should come across at the best blackjack casino sites:

Welcome Offer

This is the first promotion you will come across when joining an online casino. It is just for new players and it gives them a reward of some kind for signing up. This reward is usually free spins or bonus money - at some sites, you can earn both. To qualify for a welcome offer, you have to make your first deposit. This needs to be of a minimum amount (e.g. £10) or greater.

Deposit Match Bonus

This is any kind of bonus for which you have to make a deposit to receive the reward. At many blackjack casino sites, there are deposit match bonuses for both new players (i.e. the welcome offer) and current members (casinos usually call this a reload bonus). To claim a deposit match bonus, you have to opt-in (if necessary) and deposit the minimum amount of money into your account.

Deposit Method Bonus

Online casinos accept multiple payment methods for both deposits and withdrawals. At some sites, there are special promotions that reward you for adding funds to your account with a certain payment method. Do this and you will receive some bonus money that you can then spend on the casino’s blackjack games.

Free Spins

Nearly every casino site has some kind of free spins offer for new players, current ones or both. Free spins are for slots only, so you cannot use them on blackjack games. Since slots are the most common type of online casino game by far, you will find more free spins promotions than blackjack ones. However, many casinos still offer bonuses for blackjack and other table games to cater for players’ different gaming preferences.

No Deposit Bonus

As its name suggests, this is a bonus that does not require you to make a deposit. Most no deposit bonuses are for new players joining a casino site. To claim one, you have to set up your account and tick the box to confirm you want the reward. When you access your account, the no deposit bonus will be there, ready for you to use. It is free spins or bonus money you receive.

Cashback

Cashback is not as common as bonus money, but it can still be worthwhile. The way it works is straightforward: you spend real money on casino games during a specific time period, e.g. a week, and the casino then gives you cashback on your losses. You receive cashback as bonus money that you can spend on blackjack and other games.

Tips When Playing Blackjack Online

Since blackjack is more about just luck, there are some general tips and strategies that can help you. None of these can guarantee you a win, but they can improve your gameplay and boost your chances of doing well in the long run. Bear the following in mind the next time you play blackjack online:

One

Master Bankroll Management

First and foremost, you should always stay in control of your spending. Before gambling online for real money, determine a budget and stick to it. Only spend money that you can afford to lose and that you do not need for other, more important things. It is also important that you avoid chasing losses. In other words, if you are having a losing streak, do not keep playing hoping to win because there is no guarantee this will happen.

Two

Master Betting Strategies

There are quite a few general betting strategies that people use when playing blackjack. These are common in both real-world and online versions of the game. A good example is the Martingale strategy, which has you double your bet after a loss. When you win, you will recoup your previous bets and end up with a profit equal to your original wager. If you want to use strategies, test them out when playing free blackjack games first.

Three

Avoid All-In Bets

When playing blackjack for real money, you should avoid wagering all your money on a single bet. It is always best to spread your budget across multiple, smaller bets. By doing this, you will have less of a risk and could make some money back. If you risk it all on a single bet, you could stand to win a decent amount of money, but if the bet loses, you will have wasted all your money.

Four

Use Card Counting Techniques

Card counting is where you keep track of what cards have come up in a game of blackjack. By doing this, you should have a good idea of what cards are still in the deck and whether or not you have an advantage. You would then base your decisions on what you know. Some brick-and-mortar casinos ban card counting. Online blackjack games shuffle the deck so often that card counting is practically ineffective.

Online Blackjack Final Thoughts

Over the years, UK players have enjoyed multiple online games. However, blackjack is one consistent classic game that withstands the test of time. The best online blackjack sites offer different game variations. Also, they are secure, reliable, and have multiple banking options. With such an experience, the blackjack sites will remain popular and attract more players. However, remember to play responsibly at all times.
