We update this page when we find outdated information or a relevant change. For options we think stand out, see our best online casino UK page.

Customer service, payment methods and security are worth checking before you sign up, and the right choice depends on what you want from a casino.

Our casino reviews also include comments from members of the Mr. Gamble forum. These reflect individual player experiences and aren’t conclusions reached by our editorial team.

UK Online Casinos Defined

A UK online casino is a website or app that offers casino games such as slots, roulette and blackjack to players in the UK. UK casinos must follow UK Gambling Commission (UKGC) rules.

Each casino sets its own bonuses, payment methods and terms, so two UK casinos can offer very different experiences, even though UKGC rules apply to both.

How to Compare Online Casinos?

Comparing casinos starts with weighing up your options. Each casino offers slightly different benefits: some focus on bonuses, others on safety, others on games. What is available also depends on where you live, and UK players should only use casinos that hold a UKGC licence.

The right casino for you is the one that fits what you want from it. A bonus is more than its headline amount, so read its terms.

Distinguishing Casino Categories

Want to compare casinos online? There are different types of casinos and brands specialising in their own unique strengths. Casinos differ in what they specialise in, and players often have specific preferences. We have grouped casino sites by type to help you compare them.

Award-Winning Casino Sites

Online casino operators can win industry awards for their achievements. Awards often go to large, well-known brands, but they don’t guarantee a good experience for every player, so don’t rely on awards alone.

While many casino sites belong to well-known brands, there are also UK casino sites run by smaller operators that hold the same UKGC licence and follow the same regulations. These sites can sometimes offer a different experience or game selection compared with big-name platforms, but they must still meet the same UKGC requirements for transparency and player protection.

Which casino suits you comes down to your own preferences. Check the licence, the bonus terms and the payment options before you sign up.

Compare UK Casinos Only

UK casino sites are built for British players, with pounds sterling, UK payment methods and games with familiar themes. UK online casino sites also try to stand out with promotions such as tournaments, raffles or exclusive bonus offers.

New Casino Sites

New casino sites are casinos that have recently launched in the UK. They often arrive with modern designs, newer game libraries and introductory offers for new customers, which can make them appealing if you want something different from the established brands.

A newer casino has had less time to build a track record, so open its review and check the offer terms before you sign up. That way you know exactly what you’re getting.

Low Deposit Casinos

Not every player wants to start with a large deposit, and many UK casinos set a low minimum deposit, such as £5 or £10. A low minimum can make it easier to try a site and its welcome offer without committing a lot at once.

Low deposits still involve real money, so decide how much you want to spend before you play. For more options, see our no minimum deposit casino UK page.

Mr. Gamble's Criteria for UK Casino Sites Comparisons

We check every listed casino’s licence on the UK Gambling Commission public register and read the terms of each offer. Where a casino’s review has a casino test section, our team has tested that site ourselves with a real-money deposit.

The areas we consider when comparing UK online casinos are:

• A valid UKGC licence.
• Responsible gambling tools, such as deposit limits, time-outs and self-exclusion.
• Bonus terms and conditions.
• Availability to UK players.
• Website and mobile experience.
• Payment methods and withdrawals, including limits, fees and processing times.
• Games and providers.
• Customer support.

Each casino’s review goes into more detail on these areas.

How to Compare and Choose Online Casinos

Beginner’s Checklist for Analysing Online Casinos

If you are new to online casinos, it can be hard to know where to start. Many casino sites are open to adults aged 18 and over, and they differ in the bonuses, payment methods and games they offer.

This is why we created Mr. Gamble: to bring transparency to the industry and help players compare casinos. If you are a beginner, here are some tips on choosing an online casino that suits you.

1. Make sure the UK casino site has a UK licence from the United Kingdom Gambling Commission (UKGC). More on this below.
2. Check if the casino has favourable conditions for deposits and withdrawals, or low wagering requirements.
3. Read casino reviews, including ours, and check the details against the casino’s own terms.
4. Expect to provide ID when you register, and be ready for the casino to ask for further documents before a withdrawal.
5. Set deposit limits before you play. More on safer gambling tools below.
6. If you have a question, contact support and see how quickly and clearly they respond.

Online Casino Bonus Comparison

Many UK online casinos offer bonuses to attract new players. Our guide to the best bonuses offered at online casinos in the UK is a good place to start, and each offer is easier to judge once you look at its wagering requirement, expiry, eligible games and withdrawal limits.

UK casino sites often run ongoing promotions as well as welcome offers. Only deposit what you’d planned to spend, not just to unlock an offer.”

Comparing Top Online Casino Games UK

Online casino games range from classics with simple rules to newer games with more complex features, so there is plenty to choose from.

Which games you enjoy most is a matter of personal preference. Common choices include slots, poker, blackjack and craps.

If you want games that are quick to pick up, slots and roulette are simple to learn. If you care about the odds, check each game’s return to player (RTP) figure and rules. RTP is a long-run average over a very large number of rounds, so it doesn’t predict the result of a single session.

Below, we provide brief explanations of some popular online casino games as well as a list of gambling sites where you can play these games.

Compare Live Casinos Online and Live Dealer Casinos

Live dealer casinos stream live casino games run by a real person acting as a croupier. Live casino games range from roulette and bingo to card games like blackjack, poker and baccarat.

The advantage of a live casino is that you can interact with a real dealer, which some players find more realistic. You can compare live casinos and live dealer casinos below:

Casinos With Blackjack for UK Players

Blackjack, also known as Twenty-One, is a card game with a long history. It is offered by many land-based and online casinos.

There are many variations of blackjack, including Pontoon, Spanish 21, Double Exposure, Progressive Blackjack and Blackjack Switch. Which ones you can play depends on the casino.

Online Casinos With Roulette in the UK

Roulette is a popular online casino game with simple rules. A wheel with numbered pockets is spun, a small ball is thrown in, and you try to predict where it will land.

There are several types of roulette, most notably European, French and American roulette.

Online UK Casinos With Baccarat 

Baccarat, or baccara, is another classic casino game offered by many gambling sites.

There are three popular variations of this game, namely Baccarat Chemin de Fer, Baccarat Banque, and Punto Banco. Check which version you can play at a casino by reading the game’s description and rules.

UK Casinos With Bingo

Online bingo is a popular leisure activity for people in the UK. Players mark off numbers on their cards as the numbers are drawn at random.

Players win by completing a line or pattern, such as a full house.

Online Casino Software and Game Providers

Casinos don’t usually develop their games themselves. Software providers create them.

Many casino gaming software providers have their own specialities and use different technologies to develop their games.

NetEnt is a software provider founded in Sweden, with a library that includes classic, progressive and video slots.

Microgaming supplies games to online casinos, including themed slots.

Playtech supplies casino games and software to online casinos, including slots, live dealer games and progressive jackpots.

Deposit and Withdrawals in Online Casinos

Online casinos offer a wide range of banking options nowadays, and not every site offers the same choices. Some accept a long list of less-known payment providers, while others stick to the major banking companies. UK online casinos tend to share at least a few payment methods

The method you pick can shape your experience. Fees, withdrawal limits and withdrawal times are set out in each casino’s terms and differ between casinos, and faster withdrawals don’t necessarily mean higher fees. Some payment methods, such as certain e-wallets, are also excluded from bonuses, so check the offer terms before you deposit.

Choosing a payment method is a personal decision. You are likely already using one of the options UK online casinos accept to make instant payments.

Casinos Accepting Card Payments

Visa and Mastercard debit cards are offered by many gambling sites, and they are an easy choice if you’d like to use a card you already have. Credit cards can’t be used for gambling in the UK.

Other options, such as Revolut, are less common. Besides cards, there are plenty of other ways to deposit and withdraw.

Casinos With E-Wallets

E-wallets, such as Skrill and Neteller, are a common way to deposit and withdraw at online casinos. They keep your payments in one account, which some players prefer to using a card directly.

These are some of the payment methods you’ll see most often at online casinos:

• Skrill
• Neteller

Pay by phone casino sites allow players in the UK to make deposits through their mobile carriers. Instead of entering card or bank details, you enter your mobile number and confirm the payment via SMS or a pop-up. The amount is either added to your monthly phone bill or deducted from your prepaid balance.

Deposit limits are low and vary by provider and casino. You can’t withdraw using this method, so you’ll need another method to withdraw.

Many major UK mobile operators allow paying by phone through services like Boku, Fonix and Siru Mobile.

Online casino with PayPal sites let you deposit and withdraw through your PayPal account. A big draw for many players is that you don’t share your bank card details directly with the casino.

Using PayPal doesn’t change how a casino is licensed or how good its games and support are, so the licence and offer terms are still worth a look.

Play with Desktop, Mobile, Tablet, and More

Many online casinos can be played on desktop, mobile and tablet, and a few offer VR. Each device offers a different way to play, so pick whichever suits you.

Compare Mobile Casinos

Mobile casino sites let you play on a smartphone or tablet with an internet connection. Mobile casinos usually let you play games, contact customer service and make payments from your phone or tablet, but features can differ between casinos.

Because you can play from anywhere, keep an eye on how much time and money you are spending.

No Download Casinos

No download casinos let you play in your web browser without installing software, so you can open a site and start playing on desktop or mobile.

Many casinos also offer an app, so check what the site you choose offers.

VR Casino and Virtual Casino Games

Virtual reality casino games place you in a simulated casino using a VR headset, which makes for a very different experience from a standard casino site.

VR casinos are still uncommon, and their game selection may be smaller than at standard online casinos.

Gambling Laws and Regulations in the UK

Under the Gambling Act 2005, the UK Gambling Commission has the official authority to issue, approve and regulate gambling licences. If you play at a UK-based online casino, make sure it holds a licence from the UKGC.

A UKGC licence means the casino is required to meet UKGC standards on fair and open gambling and on protecting players. A licence alone doesn’t guarantee a good experience. Operators that break licence conditions can face fines or lose their licence.

Licensing authorities set different rules, and UK players should look for a UKGC licence.

Online Casinos and Responsible Gambling

All UKGC-licensed online casinos must offer responsible gambling tools. Responsible gambling is a subject that the UKGC heavily promotes for the safety of the players. At Mr. Gamble, we also take responsible gambling factors into account when reviewing casinos.

Responsible gambling tools should include the following:

1. Deposit limits.
2. Reality checks that show how long you have been playing.
3. Time-outs and self-exclusion.
4. A transparent transaction history, including deposits, withdrawals, wins and losses.
5. Links to support organisations.

Gambling carries a risk of losing money, so only play with money you can afford to lose. To self-exclude from all UKGC-licensed online casinos at once, use GAMSTOP. For support, call the GamCare National Gambling Helpline on 0808 8020 133, free and open 24/7.
