How to Choose a Blackjack Site?

We’ve given you the 7 online blackjack sites we’d recommend joining if you’re from the UK. But we’re also going to justify our ratings by taking you through our reviewing process.

That’s why we have provided you with a list of different elements of a blackjack site. We’ll take a look at each individually shortly.

First, we’re going to make our top listing more specific. As players, you all have different wants and needs. Some of you are after online blackjack bonuses, for instance, while others look for the best mobile casino experience. Here’s a more detailed rankings table below.

As a UK player, you’re bound to have heard of Betfair. They’re over 2 decades old and one of the top online casinos around. What you may not realise is that they also have a strong online blackjack product.

They have a total of 10 RNG variants of the classic table game, at the time of writing. But their major selling point is that courtesy of Playtech they offer jackpot versions of online blackjack. One example is Frankie Dettori's Magic Seven Blackjack.

Betfair Casino is also home to several promotions which can be claimed playing online blackjack. Plus, their standard wagering requirements state that blackjack has a 50% contribution. Compared to other competitors, this is extremely generous, as we’ll find out later when we discuss bonuses.

Blackjack Online Game Variations – The UK’s Top Picks

Most of you will know how to play blackjack. For those who don’t, we’ll provide the basics later on. But what you may not realise is that the online world has opened the doors to 100+ variations.

mutlihand blackjack online

Aside from providing an exciting new experience, tweaking the rules has an effect on the return to player. As you probably know, blackjack is already one of the high RTP casino games. This is what sets it ahead of slot games.

Some providers, like Playtech, have managed to lower the house edge even further. We’ll take a closer look at some of the top online blackjack games and their respective RTP below.

Blackjack Game% RTPWhere to Play in the UK
Blackjack Switch99.87%Paddy Power Casino
Atlantic City Blackjack Gold Series99.65%Betway Casino
European Blackjack99.60%Energy Casino
Multi-Hand Blackjack99.60%Leovegas Casino
Frankie Dettori's Magic Seven Blackjack98.49% - 99.58% RTPBetfair Casino
First Person Blackjack99.21%Rizk Casino

Above we have looked at some of the more popular games available at UK blackjack sites. Choosing the right one for you will depend on what you’re after from the game.

Playtech’s Blackjack Switch, for instance, allows you to play with two hands, which increases your chances of winning. The previously mentioned, Frankie Dettori's Magic Seven Blackjack, on the other hand, bears a much higher house edge. But you’re able to win up to 7,777x your bet. European Blackjack is a staple at online casinos.

Top Software Providers for Online Blackjack

At the heart of online blackjack games are their providers, which is what we’ll look into next. As you probably know, there are hundreds of games studios out there. Most are focused on online slots but will still include one or two table games.

The best online blackjack providers will, of course, have a much wider range of variations. We have listed them below.

Blackjack ProviderStrengthWhere to Play in the UK
NetEntQuality Audio-VisualsLeoVegas Casino
MicrogamingWide Range of GamesBetway Casino
PlaytechVersatile Options such as ProgressivesBetfair Casino

NetEnt, Microgaming and Playtech are all reputable names at online casinos. They’re mostly known for their slots, particularly their jackpot games. However, as both tables above show, they have also produced numerous online blackjack games.

Not only can their games be considered safe and fair, but they are also unique and extremely realistic.

Play Online Blackjack & Claim Bonuses

We’ve helped singled out the best blackjack sites and which games to play. You’re probably wondering whether it’s possible to claim a bonus. Regulars at online casinos will already know that promotions tend to be focused on slot games. But in many cases, online blackjack is still kept in the picture.

Let’s refer back to the previously mentioned, Betfair Casino. One thing we pointed out was their fair wagering requirements with blackjack games contributing to 50% of this. As a general rule table games almost always contribute less to wagering. This is down to the fact that they tend to have a higher return to players than online slot games. Blackjack, for instance, usually contributes to somewhere between 10 and 20%.

While it is completely possible to claim bonuses playing online blackjack, it’s not the best game to play if you want to maximise your wins.

Aside from the above, some online blackjack sites offer promotions specifically for this game. 888 Casino is one example, with regular offers on specific blackjack games. These types of bonuses are harder to come by, though, which is why you need to be on the constant lookout.

Changes in the UK laws relating to gaming duties have led to a reduction in the number of no deposit bonuses. When casinos do offer them, they’re mostly in the form of free spins and eligible on slots only.

If you check out our no deposit offers on our dedicated page, you will, however, notice that a select few casinos offer bonus cash. An even smaller selection of these same gaming sites open up their sign-up bonuses to online blackjack players. 888 Casino and their notorious ‘FreePlay Bonus’ is one example.

The Best Mobile Blackjack Apps

Nowadays, mobile blackjack is even more popular than the desktop version. Software providers have, of course, adapted to these changes in demand. But so have online casinos.

As always, there are a few that stand ahead of the grown, both in terms of interface and user experience. Below are some of our top picks for mobile blackjack sites in the UK.

Mobile Blackjack CasinoNo. of Mobile Blackjack GamesNative App Available
888 Casino8Yes
LeoVegas Casino20Yes
BetVictor Casino10Yes

Nowadays, it’s not about the number of mobile blackjack games you offer. This is because most desktop games are devised using HTML-5 software. The best experience is based on ease of use and overall quality of gameplay.

While native apps are often faster to load, they aren’t essential in offering a top mobile blackjack experience. Casino Gods, for instance, has devised a state of the art instant play web-app that puts it up there with the best.

Real Money Blackjack – Deposits & Withdrawals

Online blackjack sites usually give you two options; playing for free or for real money. Demos are a good opportunity to learn the ropes. If you want to be in with a chance of cashing out, then you’ll need to play real money blackjack games. And that involves making a deposit.

If you check back to our list of the blackjack sites, you’ll notice that most provide a decent range of payment options. As always, though, quality should trump quantity. And as a player from the UK, region-specific options like PayPal are what you want to see. Below we’ve taken our top sites from earlier on and illustrated their banking options.

Blackjack SiteTop UK Payment OptionsWithdrawal Limits
Betfair CasinoPaypal, Apple Pay, Skrill, Neteller, MuchBetter, VisaN/A
888 CasinoPayPal, Apple Pay, Skrill, Boku, MuchBetter, Netller, Paysafecard, Trustly, Visa £20 - £10,000
Casimba CasinoSkrill, Neteller, Paysafecard, Visa£20 - £5,000

Apple Pay is another UK friendly payment method that’s slowly catching on. This again is proof of the move towards mobile gaming.

One thing to be aware of is that as of April 2020, players from the UK are no longer able to make credit card transactions. Debit cards like VISA are of course still accepted at online blackjack sites.

Are Online Blackjack Sites Safe?

Playing online blackjack for real money does, of course, carry some risks. Checking the house edge for each game can act as a guide, but it won’t ensure game fairness. Playing at a trusted site, however, will. Here’s a safety checklist below to help you.

  • Look for licence information (all UK casinos must be licensed by the UKGC)
  • Ensure that the casino makes use of RNG blackjack software that is fully audited
  • The blackjack site should use the latest SSL technology
  • Terms and conditions should be clear and easy to access
  • Check back to the privacy policy for more security details

The above should ensure that the online blackjack site you opt for is safe. In fact, all of the casinos that we recommend are in line with this same list.

Managing Your Money

A trustworthy blackjack site will look to protect you and your funds. But you’ll also need to take several steps to ensure appropriate money management. Again, we’ll provide a list of points to keep in mind when playing blackjack for real money.

  • Keep your personal bankroll and gaming funds separate
  • Check the RTP and rules for each online blackjack variation
  • Stick to a staking plan that suits your budget
  • Know when to stop

How to Play Blackjack Online?

Blackjack is sometimes referred to as ‘21’. The latter gives you a better understanding of what the name is about. The hand value closest to 21 wins. But if you score a value of anything higher, you go bust.

Below we have listed the value for each different card type.

  • Face Cards: 10
  • Ace Cards: 1 or 11
  • All Other Cards: card value

In order to begin playing online blackjack, you’ll be asked to place a bet. Each hand is then dealt 2 cards. In some cases, both are placed face up whereas other game variations follow the hole card rule. One card is kept face down, which of course has an effect on the game’s house edge. As a player, you have several options which include standing, hitting, doubling or splitting.

As you can see from the above, there are a number of terms that you need to be familiar with when playing online blackjack. We explain them all in the table below.

Blackjack Term Description
Hole Card 2nd card is kept face down
Hit Ask for another card
Stand Stick with your current hand
Split Pairs can be split into 2 separate hands
Double Double your bet to receive 1 more card
Bust Hand exceeds 21 – automatic loss
Blackjack An Ace & a 10 – Best hand in the game

The rules are simple enough to grasp, however, as we have seen, there are hundreds of variations available at online blackjack sites. Each comes with specific house rules, which in turn affect the RTP.

One example is the Surrender rule which occurs when the dealer receives an Ace or a 10-value as a first card. Players can opt for an early or late surrender which lets them opt-out of the game before or after the dealer checks whether they have landed Blackjack.

This one of the many rules you’ll need to check for. They can provide an exciting twist to the game, just as long as you’re aware of them.

How to Win at Online Blackjack?

As with any other casino game, online blackjack is based on luck. Card counting used to be seen as an answer, but this is no longer the case, particularly when playing online. Software providers use state-of-art RNG software to ensure this further. It is impossible to predict when you’re dealt a winning hand.

A slight plus side to online blackjack is that over the year’s enthusiasts have devised a basic strategy. While it cannot guarantee a win, it can significantly improve your results. Combined with proper money management, this can definitely prove handy at blackjack sites.
