How We Rank Top UK Online Casinos at KingCasinoBonus UK

KingCasinoBonus.uk expert and CEO, Ionut Catalin Marin, created our ranking system for the best online casinos in the UK. Rooted in his detailed and methodical process, we update our list with only top casino sites that meet our experts’ high standards.

Have a deeper look at our casino review strategy. We use 6 criteria and a thorough process to ensure that you are satisfied with your choice:

Our Best Online Casino UK Review Criteria

• Safety and Licensing: We prioritise your safety when ranking the best online casinos UK and select only UKGC-approved sites on this page. You enjoy fully respected player rights under the UK Gambling Act with fair games and transparent T&Cs. Our analysis of the customer support and responsible gambling tools are included here to ensure you get links to proper help if needed. 
• Slot Games: When evaluating online casino games, our expert reviewers consider the variety of slots – we expect at least 500 classic and video slots.
• Live Games: A top casino site must have live blackjack, roulette, baccarat or craps for an immersive gaming experience.
• Payments: We expect various payment methods to meet any player’s needs. Another deciding factor for us is the payout processing time. We check our UK online casinos’ track record for timely payouts, each method’s payout speed, and the transaction limits.
• Promotions: Our experts test online casino promotions manually. For each selected online casino you see on this page, we underwent an in-depth testing process, signing up, claiming the welcome bonus, and evaluating the Bonus Policy. We note the quality and quantity of bonuses offered in our reviews and the restrictions on who can claim them or how they can be used.
• Mobile interface: Our testing process unfolds both on computers and mobile devices to ensure ease of use, speed of loading times and compatibility across iOS and Android browsers. Additionally, we test any mobile apps available on the official app stores.

Most used phone models for UK casinos

Why mobile online casinos are better than land-based casinos

• All the casino features are optimised and work well on mobile, so there’s no downside.
• Since we carry our mobile phones everywhere, casinos can be accessed everywhere.
• Mobile online casinos have a 24/7 schedule, making them more accessible than land-based venues that work on a strict schedule.
• The number of games available in a mobile casino is sometimes 1000 times larger than the number of slot machines and game tables in a land-based casino.

Apps vs browser online casino comparison

From what we’ve seen in the 8 years of analysing casinos, mobile browser casino play is still 1.5x more popular than downloading an online casino app. It is easier and faster, and you don’t need to install anything on your phone. Ultimately, the choice is yours.

Tips to optimize your mobile experience

• Don’t gamble on outdated software or devices. They might be glitchy and freeze frequently, and you don’t want that to happen when you are playing with real money bets
• Only play on safe casinos licensed by the UKGC and verified by KingCasinoBonus.uk. That way, you can be protected from scams.
• Make sure to set reminders for how much you play and how much you spend. All UK casinos have responsible gambling tools you should use.
• When starting to play at a new casino, choose small bets on a game you know or know the rules to.
• Have a steady internet connection when making bets, so you don’t lose connection when you play.

How to Get Started in Online Casinos: A-Z New Player Guide

Our industry experts are real-life gamblers just like you, and we will guide you from registering to your favourite UK online casino.

How to compare the current best online casinos UK using our site

You can’t just register on the first site that catches your attention. Comparing your online casinos using our criteria allows you to choose a site based on the real facts we share with you.

• Our curated selections make security checks obsolete.
• We group the best UKGC-licensed casinos according to specific criteria.
• Some of the most popular filters in the UK include slots, live game payouts or bonuses.

When you select a casino, you need to know your gambler profile and what you want from a casino. Then, you need to have a gambling budget ready.

How to sign up for an online casino account

1. Creating a new profile on one of the best online casinos in the UK is standard.
2. You have a few boxes where you must write down your personal information, like name and address, contact info, and sometimes a few details about a payment method that you will link to your gambler account.
3. Remember not to try to use details that do not belong to you when creating an account. You must send accurate data and only use your IDs and source of funds.

To pretend you are someone else by using their data online is a criminal offence in the UK.

Why do you need to complete the KYC process?

When a casino asks you to send clear pictures, scans, or screenshots of your IDs, they do it to verify that the name and address that you entered while signing up are actually yours. The KYC process is a paperwork verification method that adds an extra layer of safety and support to the entire gambling industry by combating money laundering.

All UK casinos will ask you for financial KYC at a certain point. There, you need to show them where you get your funds and demonstrate that the means of payment that you’ve been using are yours or assigned in your name.

Strategic Play: Tips to Minimize Risk in Online Casinos

How to use sign-up bonuses in UK online casinos safely

1. Start with free spins on sign-up in online casinos since slots are the easiest game.
2. You should move up to deposit bonuses only after comparing the best options in the UK.
3. If you choose no deposit casino bonuses from verified sources like our experts’ list, you enjoy an extra layer of safety and complete information in an easy-to-digest presentation.

Always read the Bonus Terms

Free bonuses come with strings attached, so it’s best to understand all your requirements before using them. Moreover, regarding 1st deposit offers on sign-up, not reading the bonus rules may have negative financial implications.

Sister sites functioning on the same white-label license may restrict your access to their sign-up bonus. To counter that, you can choose from our new independent casino list for 2024.

Here’s a quick reminder of the most important bonus terms at online casinos:

• Min deposit: the amount you need to deposit to activate your bonus. It starts at £1, £5 or £10 in the UK;
• Bonus value: the amount of promotional funds you receive from the casino site after your deposit has been processed;
• Eligibility: some bonuses are for new players, while others, particularly reload bonuses, are suitable to claim only by existing players;
• Welcome package: a promotional bundle that contains bonuses for multiple deposits along with free spins, usually spread between 1-5 days;
• Wagering requirement: the number of times you need to play through the bonus value or the deposit and bonus value combined before cashing out real money from it;
• Expiry date: the date after which wagering the bonus is no longer available and you lose any unused bonus funds.

Best Payment Methods to Use in UK Online Casino Sites

Compare the most convenient methods for depositing and cashout in UK online casinos. The transaction limits and processing time values are estimates based on our experience with the best online casinos reviewed on this page.

Our best recommendation for UK players is to choose a PayPal casino that combines payment speed and reasonable limits for the average player.

You should settle for a debit card if you deposit over £5,000.

Top 20 Slots UK Players Play in Online Casinos

This top 20 slots table results from a simple formula. We looked at special features, slot providers and how many UK players have claimed bonuses in May for each slot game. We also tell you where to play each game with a bonus:

Top-Rated Online Slots Providers in the UK Industry

NetEnt: our top choice for slots – ⭐4.4/5

• Best for: video slots, low volatility games
• Alternatives: Red Tiger Gaming, Quickspin
• Best bonus for NetEnt: 100 no deposit spins on Starburst at Luck Casino

We know the online casino UK industry and market trends in and out. Over the years, we have observed that NetEnt has had a steady top position within the UK preferences, including when partnering with our best online NetEnt casinos in the UK.

If you’re asking why does NetEnt take the lead, they are game creators that deliver complete products for slot play. Their games contain pleasing graphics that attract your attention but are not over the top while catering to the needs of players on a budget.

Microgaming: best creator of jackpot slots – ⭐ 4.4/5

• Best for: progressive jackpots, Mega Moolah
• Alternatives: Playtech
• Best bonus for Microgaming: up to 500 bonus spins at Immortal Wins

Even though the classic slots games hit the high standards, Microgaming has created its reputation as a well-known jackpot creator studio, prompting us to reflect this quality in our rating. With over 30 jackpot slots created, this is the most successful provider for progressive options in UK online casinos.

Famous Microgaming jackpot titles

• Mega Moolah
• Major Millions
• Treasure Nile

The game themes are quite varied in this portfolio, and they can range from classic fruit games to more adventurous themes (Immortal Romance, for example) to branded games like the Game of Thrones slot.

Play’n Go: most popular UK online slot provider – ⭐4.3/5

• Best for: pop-culture slots, branded slots, TV-show slots
• Alternatives: NetEnt, Quickfire
• Best bonus for Play’n Go: 10 free spins no deposit + 100% up to 75 + 75 Book of Dead spins at Lucky Vegas Casino 

Play’n Go has already created more than 200 games, and they constantly release new releases that explore new themes and features, which explains our high rating for this innovative online casino UK games provider.

Famous games from Play’n G0

• Rich Wilde and the Book of Dead
• Reactoonz
• Fire Joker

Play’n Go slot animations and special features are always very clear and well spread throughout a gaming session. You can consult the winning combinations through the game settings and informative table in each slot.

Big Time Gaming: the hotspot for Megaways – ⭐4.1/5

• Best for: Megaways slots, multi-payline slots
• Alternatives: IGT
• Best bonus for Big Time Gaming: 30 no wagering spins at Bally Casino

We rate Big Time Gaming with 4/5 because their games are always trending on the UK market. The basic reason is that the integral features work well with an average session, and the graphics are great on any mobile device.

Main qualities of BTG games

• The clean graphics don’t seem overcrowded
• Some special features are added to make the experience engaging

A mark of uniqueness comes from the “Megaways” features, which you’ll often see in their game titles.

Megaways games allow each spin to convert a random number of symbols, thus changing the grid every time. On average, the lowest number of symbols that can fall is 2, while the higher-margin goes to 7 mostly. It takes a different perspective regarding what is regarded as the usual gameplay.

Thunderkick: new online casino game provider – ⭐4.1/5

• Best for: new casino games
• Alternatives: Eyecon
• Best bonus for Thunderkick: 30 no wagering spins at Bet365

We have decided to include them on our listing of best slot providers for the best casino sites because their portfolio is solely focused on slots and because they have had successful collaborations with other providers on our list.

Themes approached by Thunderkick

• Ancient history/mythology
• Adventure
• Arcade-inspired games.

After extensive hours of research on this provider, we found a common theme: stakes on certain bets can be multiplied by thousands, according to the game tables. The initial game features are not guaranteed, as the best online casinos UK may change them, so your safest route is to read each site’s terms to see the latest changes.

Safety First! How the UKGC Protects Your Security

The United Kingdom Gambling Commission regulates all UK online gambling and betting activities. This institution licenses online and land-based operators and checks if the products they offer respect the legislation.

They are the ones that create, update, and enforce the legislation. They do that as a result of the joint effort of law experts, psychologists, gambling addiction therapists, and operators alike. Their goal is to set up healthy standards for all sides.

How the UKGC protects you

The UKGC enforces strict standards upon online casinos which act as shields that protect you from scams:

• The UKGC protects your financial situation by not allowing operators to steal your money, lock it in their accounts for no reason, not allowing you to take it back, etc.
• On top of that, they force casinos to be transparent with you. The operator is bound to inform you, in simple terms, of what happens to your funds, where they are stored, in what conditions can they be transferred, etc.
• The casinos are also required to protect your personal data. It needs to be stored securely, not accessible to anyone else, collected minimally only with the details that are needed to verify that the account is yours and you are an adult.

License granting system for online casinos in the UK

1. When a UK online casino applies for a license, all these features fall under supervision.
2. The site is tested for over 6 months before they get the seal of approval.
3. Then, randomly, they go back and test if the terms and promises’ validity is still respected.
4. A license can be revoked anytime if the provisions are not respected.

Read the full guide to what the UKGC does to understand better the extent of its regulations and protections for UK gamblers.

How to verify the casino license and stay safe

Here’s the process we go through when verifying. We suggest you follow the same trail as us:

1. Go to the main page of a casino of choice and scroll down to the footer.
2. Read the text there (sometimes it might be presented in a smaller font than the rest) and scan until you get to the part with a hyperlink.
3. Click on the hyperlink. It should redirect you to the UKGC site, specifically the page where the main operator is listed, and all their licenses are listed (expired, new, or pending).

If you see a green text that says “ACTIVE” under the Status column, the specific license is valid and currently in work.

That’s it! If you see something similar to the screenshot above, that means that the UKGC licenses your casino at the moment, and it has passed all the safety standards required.

If you can’t see the number in the site’s footer or the main terms and conditions page, if you can’t see a hyperlink anywhere, or if the link sends you to a different page or a page that doesn’t have the green text, stay away from that casino! It is most likely not licensed and can be a scam!
