Narrowing Down to Top 50 Online Casinos UK

Let’s now talk about other important areas in which casino operators must excel to pop up on our list. These drivers affect the final score of the site in direct way. So, the next criteria in our blueprint to outline the top fifty online casinos for British punters are:

1. Track record and player reviews. Our experts visit different gambling forums to see what experience UK gamblers had on the site. Brands with a fine reputation and a clean record without penalties definitely get our approval.
2. Game and software variety. Needless to say, to be the best UK casinos they must have a diverse range of pastimes. We look at casual video slots, table and card games and live dealer action as standard. Cumulative jackpots, crash gambling and scratch cards contribute to better rankings. We also check what companies supply software and their rep.
3. Payment methods accepted. We assess the UK’s best online casinos’ cashboxes for available deposit/withdrawal solutions. British players, all as one, want to add money to their gaming balance and cash out real gains easily. So, for sure, there must be options like debit Visa/Mastercard, PayPal, Boku, Neteller and bank transfers, all common in the region.
4. Bonuses and promotions. Our suggested real money casinos equally well treat their new and loyal members. So UK residents can count on a warm welcome (extra money, FS or both) and regular proposals (reloads, cashback) with lavish benefits and reasonable playthroughs.
5. Customer care and support. Live chat 24/7 and email as contact ways are always a must for the top casinos in the UK. Friendly agents with good knowledge of the site’s services deserve extra points from our team. An extensive FAQ page with valuable info is also a huge positive in our view.

Checking these angles helps us understand what a British gambler can expect when they register to play at a certain real money casino.

Best Online Casinos Ranked by Popular Games

Backed by licence and safety certificates, good real money casinos in the UK have another very apparent thing in common. This refers to massive libraries that boast myriad gaming options, sometimes as big as 10,000, from standout providers. A diverse range of pastimes on offer is the sweetest lure for both — newbies and savvy punters. Therefore, when we analyse and rank the best gambling sites for UK residents, we always pay attention to how tightly their shelves are packed with varying games of chance.

Some operators focus more on slots, while others are sharpened to furnish blackjack, roulette, baccarat, poker and other table fun. Here we have another split into casino experience subgroups: RNG games and Live (real-time) streams with skilled croupiers. This matters, so our experts pinpoint the focus of attention of each new online casino for real money and then spell out its specifics in the review. Reading it, a British gambler will clearly understand whether the site can satisfy his/her needs or better leave it and keep looking. Below we explain every category in more detail.

Finest Slots Casinos for UK Players

From our perspective, slot machines fit perfectly into the world of real and online gambling alike. We’ve seen no remote casino which doesn’t add online slots to the lobby, there’re always at least a few hundred titles available. Major factors behind their crazy traction are the simplicity, delight and acute experience they offer. With rich graphics at an amazing level of detail, immersive sound effects and themed bonus rounds, each release is a mesmerising experience.

​

Playing at the top online casinos, UK residents deserve a broad choice of titles with bonus features: jackpot, free spins, re-spins, multipliers, wild and scatter symbols. Just as a possibility of visiting multiple realms as they spin the reels. Here we mean different slot themes:

• ancient civilisations and the Far East;
• fairytales and anime;
• space adventures;
• cosy farms and villages;
• iconic films and TV shows.

During the full screening, our team considers the above to outline the best casinos open to the UK. Here are our picks for the top three slots casinos:

PeachyGames Casino

UK players drawn to video slots will find themselves lost in the lobby of Peachy Games. Enjoy a great range of 1,000+ rousing slots, including titles with exorbitant progressive jackpots. Powered by Games Global, Yggdrasil, Rabcat, NetEnt, Blueprint and numerous other recognisable companies most top casino sites partner with.

Playzee Casino

The rush of adrenaline that comes with reels spinning at Playzee never departs from the heart. With over 3,000 slots on offer, you will choose between classic and innovative mechanics. The last adds a new dimension to traditional gameplay, giving it a unique charm. The website has lots of sorting options to facilitate your quest for the desired title.

To secure this jaw-dropping experience, Amazon Slots partners with Microgaming, NetEnt, and Playtech — outstanding studious who produce jackpots. Apart from these, expect to find megaways, cascading reels, gigablox and more fun in the lobby.

Top Casino Sites to Play Roulette

According to the UKGC study, among non-slot games, today locals to the Foggy Albion most often play… drum roll… RNG and live roulette (36% of surveyed people). Does that surprise you? Because for us it’s obvious. The digital gambling era generates so many immersive variations of roulette no one can pass up. Lobbies of the best UK casinos are literally bursting with uniquely modern twists like Double Action, Mini Wheel and Lightning Roulette. Nobody has revoked good old European, French and American versions, which set in motion an adrenaline-filled spinning. This famous trio en banc adorns nearly every gaming platform in the UK. And an endless choice of live croupier options is just the cherry on top.

The best online gambling sites we see as true roulette powerhouses in the UK market are:

Best UK Casinos for Card Games Experience

Blackjack, poker and baccarat are a timeless classic. Card games gained much ground because they give players the best odds among all casino pastimes. When one employs a good strategy, the house edge may be cut to 0.5% in some variations. There are myriad choices for your pleasure and wallet: from original rules to intriguing ones with fun options and side bets. Here are a few big examples:

Most operators are black jack oriented, with poker falling by the wayside. The reason is clear: there are many custom-built UK poker sites where people can play with real money. Trying to hog the traffic would be a failure and makes no sense, therefore the focus is on other card games. As for baccarat, it is more widespread in a live format.

Top online casinos from our array have a good mix of classic and innovative setups with wide betting opportunities. Thus both high rollers and those who are currently on a budget will find something to kill time with. Cardmates’ favourites in this niche are:

Top Online Casinos with Live Dealer Tables

Premium gambling sites deliver a gateway to non-stop fun right on your screen. One more key determinant of success for such venues is the section with real dealer tables. These games transport punters from their kitchens or workplaces to the immersive atmosphere of a land casino. You'll feel right there, playing at our top sites, while wearing your pyjamas (comfort above all 🙂). All thanks to HD video, authentic design of studios from where the action is being streamed (sometimes from real casinos), and of course, human croupiers. Real-time games of chance are your go-to choice if you don’t have a gambling establishment nearby.

Vetting the best live casino sites for UK citizens, we ensure they can relish not only customary games but also fun show-style formats. Boom City, Gonzo’s Treasure Map and Deal or No Deal are among them. Now, take heed of the finest spots to play with real dealers online:

Leading Software Providers

In this section, you’ll learn where all the fun of online casinos that UK players love and cannot give up comes from. The list of software developers with whom a gambling site deals tells us much about the quality of its content. Some brands are in greater demand than others, so operators always try to provide trending games that appeal to a wide audience. We like to see the best UK casino sites powered by gaming suppliers of good repute like:

• Games Global. What’s interesting about this brand is that it embraces many smaller yet talented studios. These guys drastically improved their portfolio with Microgaming releases a few years ago. (To be exact, they purchased them.)
• NetEnt is a notable name in the world of UK online casinos. You’ve probably heard of and even tried their iconic Jumanji and Mega Fortune. These and other titles are praised for their wide betting range, high return rates and captivating experience.
• Pragmatic Play bribes with unique features that other studios attempted to follow. Their lauded daily drop slots are presented in British top casino sites. The brand delivers eye-catching and gratifying pastimes for all tastes.
• Relax Gaming produces very creative games with fun visuals. Their vivid slot machines have seduced not one thousand British players. Each new release is a real artwork, backed by enriching bonus rounds and solid RTPs.
• Nearly all casino sites in the UK engage with Playtech, another iGaming sector giant. This company mainly launches video slots and real dealer tables, yet its portfolio is much more diverse. Playtech deserves our trust as one of the most reliable developers.
• Blueprint is all about thrilling and rewarding leisure time. Scores of the best UK casinos, incl. those from our list, are powered by their games. Irrespective of your theme-related needs, this studio has something for everyone’s joy.
• Evolution is a successful enterprise that takes live casino gaming a notch higher. UK players can count on unmatched adventures while playing with human dealers at the top 50 online casinos fuelled by Evolution. Its portfolio speaks better than words.

Likewise, our experts check that products from more niche studios are available in the lobby. Content houses like Eyecon, Inspired, Slingo and Stakelogic also deserve high scores. The bigger the game count, the better. Here at Cardmates, we are sure that the choice from dozens of vendors exudes site solidity.

Bonuses at the Best Online Gambling Sites in UK

What else can affect the vogue of gambling sites are incentives and promo campaigns of various types. As a standard, we look for bonuses that unlock more fun for both – new and existing casino members. Then we inspect playthroughs to warrant that they are fair and reasonable.

Below, we’ve highlighted the most common types of bonuses one can come across at top casinos in the UK.

Aside from that, top-tier casino operators often create in-house currency. They release special coins or points to amass for completing sundry tasks. People can later exchange these assets for real funds, bonus spins and other benefits. Mind that there might be playthrough rules, too.

Best Bonuses: UK Online Casinos List

VegasLand Casino

• Carnival Welcome Pack: 150% bonus for the first three deposits up to £200 plus 100 FS
• Drops & Wins adventures with daily cash prizes from Pragmatic Play
• Frenzy Spins challenge with up to 50 extra spins daily

Winomania Casino

• Warm Welcoming Offer: 100% matched bonus up to £100 on your initial deposit plus 100 FS
• Daily Spinomania brings up to 200 Extra Spins in return for small deposits
• Weekly cashback up to 20%

Available Payment Methods

Here, we highlight the most prevalent banking solutions for moving funds in and out of a casino site. This matters as playing at the best UK casinos you should decide what services to use in either case in advance. In fact, under the rules, deposit and withdrawal must be through the same gateway. But every imperative has its exceptions, as is known. Not all deposit methods support cashout transactions; in such cases, a punter will be forced to use an alternative way.

​

Top British online casinos are flexible when it comes to payments across all devices. They cater to British players, allowing them to choose from a number of familiar options. Among them are:

• Debit cards. They provide fast and secure fund transfers with friendly limits, in both directions. Visa and MasterCard are accepted at the bulk of online casinos in the UK. Mind that processing charges may be applied, but you will see them clearly stated in the cashbox.
• Electronic wallets. A convenient and safe method to manage your finances with peace of mind, at all times. Their other upper hand is faster handling times: 15 min – 24 hours compared to 1 – 3 banking days through cards. Some top casino sites, however, eliminate UK punters from promos (most often welcome ones) if they replenish via Skrill and Neteller. In such cases, when you capriciously want to use an e-wallet, pay attention to PayPal or ecoPayz.
• Bank transfers (wire type). This method needs no introduction as it has long served visitors of legitimate online casinos. As you probably know, withdrawals this way are processed at a snail's pace and have quite high charges. Therefore wire transfers are less favoured amongst UK residents, though things have improved in recent years.
• Instant bank transfers. Easier and faster than the previous bank transfer type. Crowds of UK casino sites are friendly to IBT methods, with Trustly services being today’s premier choice. A punter simply enters their online banking account and specifies how much they want to move in/out.
• Prepaid payments. Cards or vouchers, already topped with a certain sum of money, have been detected by our experts at the best casinos for UK players. Transfers are instant and 100% anonymous, so many British players enjoy using them. But prepaid cards won’t let you cash out to them, so think of how you will take away your winnings if any.
• Money transfer apps. Apple Pay and Google Pay are among the payment options in high demand. Most gamblers have already set them up, so top online casinos commonly add these gateways to the cashier. Their huge positive is that users handle transactions with a few clicks, without much effort and extra steps.
• Pay by phone payments. Though they normally go one way (for deposits), a good share of the gambling community relies on these methods. Funding accounts at UK casino sites in this case are routed through a phone bill with minor or no fee. This gate will suit budget punters as fiat transaction limits behind are quite low. Boku operator leads the pack in the country, by the way.

Best UK Mobile Casino Sites

We believe that mobile mode has a big impact on how suitable the casino services are for you. In light of this, online casinos with solid browser versions or slick apps top our ranking. Gambling on the move is an alternative solution who love spinning reels or playing cards but hate staying at home.

The best online casino sites in UK are created with mobile users in mind. Regardless of your location and device — iOS or Android, tablet or smartphone — British players can relish their favourite games whenever it suits them. Plus, on-the-go gambling allows for breezy transactions as such platforms support mobile payment methods. All you need is a fully charged device with solid access to the Internet.

Comparison Between Latest and Old Casinos

Here we drop our online casino comparison of old-timers and recent UK market entrants. In our view, new casino sites deserve your attention if they have a requisite permit and follow safety and other standards. These operators jump over their heights to recruit new players, which means they will try to bribe you with lavish bonuses, quirky features and showy design.

Other advantageous signs of the UK’s new casino sites are just manufactured slot releases that oldies might miss and up-to-date payment solutions to facilitate your banking. Yet, there's one thing that young operators cannot beat – track record. This will take years to work on.

Top New Online Casinos on the UK Market

All the indicated casino sites have obtained a UK licence and thus are eligible to serve British players, on legal grounds.

UK Online Casinos Legislation

Online gambling in Great Britain is within the law, supported by state authorities and governed by legal rules. Thus, adult Britons (over 18) can safely sign up to play real money games on suitably licensed platforms. These days, all UK casino sites (and the industry as a whole) are under the control of the UK Gambling Commission.

This formal watchdog operates on behalf of and is sponsored by the government. To be more specific, the DCMS Committee, which stands for the Department for Digital, Culture, Media, and Sport, backs it. The UKGC, in fact, was set up by The Gambling Act 2005 to approve (or not) real money casinos and crown them as qualifying. When you select brands from our rating, you can be sure of your safety because they all have this seal of approval at the bottom of their web pages.

Responsible Gambling Policies

Legitimate online casinos, once they gain a UK licence, must go after safe gambling policies. So they furnish the requisite tools to keep their clients' experience healthy and enjoyable. For example:

• session limits to cut down on your on-site time when you overplay;
• deposit limits to regulate how much money you spend on slots at the top casino sites;
• loss limits to be automatically logged out once you lose a set maximum;
• self-exclusion means banning yourself from a certain casino site for several months or for good.

Be sure to take breaks if you feel your play is getting out of control. If you still find it challenging to opt out of tables/reels, sleek support. There are enough dedicated agencies where British punters can get free help.
