Best online casinos | Top UK casino sites (May 2025)

WHEN selecting the best online casino in the UK, there are numerous factors to consider, so we always fall back on our Sun Factor ranking system to help us be as objective and thorough as possible in our reviews.

We want a platform that excels in various areas, from the game selection and user-friendly interface on both desktop and mobile to top-shelf security and helpful customer support. We look for casinos with generous promotions for both new and existing players, which come with clear terms and conditions and manageable wagering requirements.

So, with this in mind, let’s take a look at the top UK casinos, what they do well, and, importantly, how you can get maximum value from your time online. 

Top 20 online casinos UK

🌟 Best online casino overall

Casumo is our top pick for the best online casino in the UK for ticking all of these boxes and more.

But there are certainly other fantastic choices to consider: VideoSlots if you’re a slot machine fan, Casimba for roulette lovers, Duelz for game shows, Virgin Games for a premier live casino experience, Betway for the best mobile casino experience, or Jackpot Mobile for fans of generous welcome offers, are just a few other options worth considering.

🏆 Casumo - Top online casino

Casumo is a well-established online casino known for its playful design and a highly user-friendly gaming experience. It features a strong lineup of popular titles from trusted providers like NetEnt and Microgaming, covering everything from slot games to live dealer tables.

Its gamified approach through the "Casumoverse" system is also a big selling point - players earn rewards, trophies, and progress through levels as they play, adding an extra layer of engagement and encouraging loyalty and long-term commitment. Add to that a variety of secure payment methods and reliable 24/7 customer support, and is easily a top UK online casino in our book.

🎰 Best online casino for slots

Slots or fruit machines are by far the most beloved and played online casino games, and come in many different varieties and themes. Popular types include progressive jackpots like Mega Moolah, Megaways slots such as Bonanza, and high-RTP games like Blood Suckers.

Themes are diverse, too, ranging from Egyptian (Book of Dead) and Norse mythology (Vikings Go to Valhalla) to seemingly mundane like fishing adventures (Big Bass Bonanza). Among the top slot platforms out there, VideoSlots stands out for its extensive game library, user-friendly interface, and some truly creative slot tournaments.

🥇 VideoSlots - Top casino for slots

VideoSlots lives up to its brand name and reputation as our pick for the best slot site in the UK, with over 8,000 slots from 130+ software providers, including big names like Pragmatic Play and Play’n GO. Its user-friendly interface makes exploring the massive game library a breeze. Users who like playing diverse types of slots will have plenty of game provider brands to choose from the list. VideoSlots members have a chance of picking fantastic games from multiple categories, such as jackpot slots, megaways, classic slots, video slots, and more from a vast collection of titles.

In addition to the standard tournaments, there is a unique  ‘Battle of Slots’ competition, adding a competitive multiplayer twist as players compete across various slots for prizes such as free spins and cash rewards.

With fast payout options like PayPal and Skrill, plus a generous 100% welcome bonus up to £200 + 11 wager-free spins, offers a top-tier UK slot experience for both casual and seasoned players. 

♠️ Best online casino for blackjack

Blackjack is a popular card game where both players and the dealer start with two cards. The goal is to get as close to 21 as possible without going over. Aces count as 1 or 11, face cards as 10, and players choose to hit or stand to beat the dealer’s hand.

Popular variants include classic European Blackjack, Spanish 21, Single Deck Blackjack, and innovative versions like Blackjack Switch and Pontoon. Although best played live, online casinos offer the next best thing: live dealer games such as Lightning Blackjack and Free Bet Blackjack, which offer immersive experiences with real-time interaction with dealers.

Plenty of great UK casinos offer various Blackjack variants online, but our top pick is Netbet.

🥇 NetBet - Great for blackjack

NetBet is a top choice for blackjack fans, offering a ton of options, including classic, multi-hand, and live dealer games from top providers like Pragmatic Play and Evolution. There are over 20 variants ranging from classics like American (standard) and European Blackjack to more recent variants such as Multihand Blackjack and Royal Pairs.

9

While there’s no Blackjack-themed promo, new players can get up to 500 free spins, and regulars can look forward to tons of tournaments each month with great prizes to grab.  Add to it a large selection of popular UK payment methods, a fast and responsive site with great customer support, and is easily our top choice for blackjack lovers in the UK.

🛞 Best online casino for roulette

Popular versions include European Roulette (single zero), American Roulette (double zero), and French Roulette, which offers the “La Partage” rule that allows players to recover half of their bet on 1:1 bets (red/black or odd/even) that land on zero.

Live dealer games have also grown in popularity in recent years, with games like Lightning Roulette and Immersive Roulette. Players can enjoy a range of betting options, from single numbers to red/black or odd/even, giving players numerous options on how lucky or confident in their prediction ability they feel.

Casimba is our favourite pick for roulette, but you can’t go wrong with any of our top five operators.

🥇 Casimba - Our pick for roulette online

Casimba offers a wide range of high-quality games and a sleek, modern platform that works equally well on desktop and mobile. The casino features multiple roulette variants, including European, French,  and several live dealer options such as Fireball Roulette from top providers like Evolution Gaming.

The site is mobile-friendly, fully licensed, and easy to navigate, while 24/7 customer support ensures players will always have a helping hand around. New players can claim a generous welcome bonus including a , while veterans have weekly prizes and loyalty rewards to look forward to.

🍿 Best online casino for game shows

Live casino game shows have become a major draw for UK players, offering a fun alternative to traditional casino games. Titles like Crazy Time, Monopoly Live, Deal or No Deal, and Mega Wheel combine the excitement of traditional game shows with flashy visuals and live hosts to create a TV-style gaming experience.

The best online casinos in the UK offer a wide range of these games that are well-optimised, feature engaging presenters, and offer plenty of classic gameshow experiences from the comfort of your couch.

Many popular UK online casinos have incorporated several of these games into their repertoire, but our favourite is Duelz Casino.

🥇 Duelz - Top casino for game shows

Duelz Casino offers a standout selection of live game shows, making it a top pick for UK players seeking interactive entertainment that harkens back to watching popular game shows on the telly.

Powered by leading providers like Evolution and Pragmatic Play, the platform features popular titles such as Crazy Time, Gonzo’s Treasure Map, Boom City, and Sweet Bonanza Candyland. 

9

The site's gamified design further enhances the experience, allowing players to engage in random duels with others and unlock various rewards. With a user-friendly interface and a generous welcome bonus of up to , Duelz is our favourite online casino for game shows in the UK.

♣️ Best casino for poker

Poker is a timeless favourite that blends skill, strategy, and luck. Popular formats include Texas Hold’em, Omaha, and Caribbean Stud, each offering unique twists on the hand-building and betting processes. Some players enjoy fast-paced tournament play, while others prefer cash games or live dealer versions for a more social feel when playing online.

Online casinos these days offer everything from video poker to real-time tables with professional hosts, and picking a favourite means choosing among numerous very closely matched competitors. For the best all-around poker experience with the widest selection of poker variants, though, we recommend PokerStars Casino.

🥇 PokerStars - our go-to casino for poker

PokerStars is a standout name in online poker, offering an unmatched range of formats, from cash games and tournaments to live dealer poker. The platform features Texas Hold’em, Omaha, and other popular variants, catering equally to beginners and seasoned players.  Its software is fast, intuitive to use, and reliable, with excellent filtering options and detailed stats breakdowns.

9

Combine all this with regular promotions, high-stakes events, and a strong player community, and deserves to be your go-to destination for online poker in the UK.

🤵 Best online live casino

Live casino games have surged in popularity among UK players during the COVID-19 pandemic, offering the thrill of real-time gameplay with professional dealers from the comfort of home.

Even now that we’ve been able to visit brick-and-mortar casinos for years, they are still some of the most popular games at online casinos.  From classics like blackjack and roulette to engaging game shows such as Monopoly, live casinos provide an immersive experience that combines the social aspects of classic casinos with the convenience of online play. 

To meet exceedingly high player expectations, top online casinos must offer high-quality streaming, a diverse game selection, and a great user experience, from site design to customer support. Our top pick for its great game selection, coupled with a beginner-friendly, no-nonsense approach to game lobbies, is Virgin Games casino.

🥇 Virgin Games - Best live experience

Virgin Games delivers one of the best live casino experiences in the UK, thanks to its well-designed online platform and wide selection of real-time table games.

Players can enjoy live versions of blackjack, roulette, baccarat, and more, hosted by professional dealers and streamed in HD. The site is easy to navigate, with a clean layout and quick loading times that make jumping into a game hassle-free. 

9

Backed by Gamesys and licensed by the UKGC, is a trusted and reliable choice for players who value a polished, approachable, and highly immersive live casino. And while there isn’t a welcome promo specifically tailored to live games, you’ll need just £10 to get access to as many as 100 free spins.

📱 Best casino app for Android and iPhone

With more players choosing to game on the go, having a simple-to-use and reliable mobile casino app is more important for online casinos than ever.

Whether you're going for a quick slot spin or two or looking to play some live online poker, a top-notch mobile experience should offer fast loading, easy navigation, and full access to the site’s games and features, including some good security measures to keep your account safe.

Our top pick for mobile play is Betway, thanks to its well-designed apps and consistent performance across both Android and iPhone devices.

🥇 Betway - Top mobile casino app

Betway’s mobile app is sleek, fast, and packed with features. Available on both Android and iOS, it offers full access to slots, table games, and live casino titles, all optimised for smaller screens. The app is easy to navigate, with quick loading times and several secure payment options.

also provides push notifications for promos and new games, making it easy to stay up to date with the latest developments. There are also tons of great promotions for both new and existing players, such as the ability to stake £10 & get 125 free spins on the Hold & Spinner slot with its latest casino promotion.

💰 Best online casino sign-up offers

Welcome offers are one of the main reasons players try out new online casinos. They give you extra value right from the start, usually in the form of bonus cash, free spins, or often both, encouraging players to step out of their comfort zone and try new games or put down larger deposits than they otherwise might. 

These deals are especially popular among new players looking to get the most out of their first deposit. While many UK casinos offer strong sign-up bonuses, our top pick is Jackpot Mobile Casino for its generous welcome package and simple, mobile-friendly setup that makes getting started quick and easy.

🥇 Jackpot Mobile - Great welcome offer

offers a generous welcome package for new UK players, totalling up to £500 in bonus funds and 150 free spins across your first three deposits. The first deposit grants a 100% match up to £100 plus 100 spins, followed by a 50% match up to £100 with 25 spins on the second deposit, and a 50% match up to £300 with 25 spins on the third. 

9

With a library of over 1,700 games from top providers like NetEnt, Microgaming, and Evolution, it offers a diverse selection of slots, table games, and live dealer options, you’ll have plenty of interesting titles to try out even after you’ve played through every part of the welcome bonus.

🔬 How we picked the best casino sites in the UK

Choosing the best online casinos is about more than just a great game and bonus selection. The top contenders in the industry need to provide an all-around exceptional user experience, from the site and app design to safety & privacy features, all the way to excellent customer support. 

That’s why we created a rigorous evaluation system known as The Sun Factor. This in-house methodology allows us to objectively assess every UK casino site we review and assign relevant ratings, ensuring that only the most reputable and well-rounded platforms make our lists. We break down every key element that matters to players, from safety and licensing to supported payment methods, game and bonus variety, and finally, customer support. 

🔒 Casino licensing and security

The first thing we look for in any online casino is a valid licence from the UK Gambling Commission (UKGC). This ensures the casino is legally allowed to operate in the UK and is held to high standards of fairness, player protection, and transparency.

We also assess whether the site uses advanced SSL encryption technology to keep players’ personal data and payment information secure. If an online casino doesn’t meet even these essential safety criteria, it doesn’t make it past the first cut.

📜 Adherence to responsible gaming standards

Responsible gambling is another non-negotiable aspect of our rating system. The best UK casino sites must offer effective tools to help players stay in control of their gaming habits. This includes the ability to set deposit limits, self-exclusion options for players who know they might struggle to stay away, and easily reachable links to support organisations like GamCare or BeGambleAware. 

We also assess how proactively the platform promotes responsible gaming, whether through on-site messaging or having dedicated support teams trained to handle problem gambling issues.

💳 Payment methods and transaction processing

A top-rated online casino needs to offer fast, secure, and flexible banking options. We evaluate whether players can use a range of trusted payment methods, including debit cards, bank transfers, popular e-wallets like PayPal, mobile favourites such as Apple and Google Pay, and even prepaid payment cards such as PaysafeCard.

We also test how quickly the casino processes deposits and especially withdrawals - no one wants to wait days or weeks for their winnings to clear.

The main online casino deposit and withdrawal methods to look out for are:

🎰 Casino games

A strong game library is central to a quality online casino experience. We examine both the variety and the quality of games on offer, including slots, table games, live dealer options, and any site-exclusive titles. Does the site have software partnerships with respected providers like NetEnt, Playtech, and Evolution, or is it focused on less-known providers or even its own unique titles? 

While we’re always happy to see new and unexpected games on sites we review, sticking to the classics has one big advantage: proven quality. That means top-tier graphics, smooth performance, typically good RTP percentages, and the use of an independently audited Random Number Generator ensuring game fairness.

🤑 Welcome offers and ongoing promotions

Let’s face it: the quality of the bonuses offered to both new and existing players is often what makes or breaks an online casino.  We dig deep into the terms and conditions of each bonus, looking at wagering requirements, expiry dates, game restrictions, and payout caps. Transparency is key here; we only recommend offers that give players genuine value without hidden catches or small font “a-ha” moments.

In addition to welcome offers, we also evaluate the generosity and frequency of ongoing promotions. A great online casino keeps rewarding loyal players long after they’ve used up the offer(s) that got them playing on the site in the first place. This includes reload bonuses, free spins, cashback deals, VIP programs, special tournament invites, and seasonal campaigns. Platforms that go the extra mile to engage and retain their player base always get extra points in our book.

The best UK casino bonus offers with fair wagering requirements are:

• Matched deposits - these offers give you bonus credit equal to the amount you deposit, e.g. if you deposit £50, you’ll receive a £50 bonus. 
• No deposit bonuses – the opposite of a deposit bonus is a no deposit bonus. Rewards are released when you perform an action that isn’t a deposit, such as completing the registration process.
• Reload bonuses – first deposit bonuses are also known as welcome bonuses because they’re for new customers. Reload bonuses are for existing customers because you’re reloading your account.
• Bonus free spins – you can play some of the top online slots, such as Starburst and Gonzo’s Quest, without spending a penny by using bonus spins. 
• Cashback – losses won’t sting as much with cashback bonuses because you receive rebates when luck isn’t on your side. 
• No wagering free spins - some casinos will not impose a wagering requirement on your free spins winnings. Those bonuses are quite popular among players, and more commonly offered nowadays.

📱 Mobile experience 

Today, the best mobile casinos are fully-stocked native apps for iOS and Android devices. 

What’s neat about the top mobile casino apps is the fact that they contain features their desktop counterparts don’t have. For example, if you download the MrQ Casino iOS app, you’ll be able to swap your alphanumeric password for Face ID logins. 

In addition to enhanced security, mobile casino apps can link directly to banking apps. This facilitates seamless transactions.

If an online casino operator doesn’t offer a mobile app, don’t worry; mobile casino sites are just as slick as their app-based counterparts. What’s more, you can create a shortcut to the mobile site on your mobile’s home screen, which makes it as accessible as an app.  

☎️ Customer support

Responsive, professional customer support can make or break a player’s experience on the site. We test each casino’s support channels, including live chat, email, and even phone options when available.

We evaluated everything from general availability and response speed to the general helpfulness of the agents.

The best UK casinos out there not only offer 24/7 assistance but also provide comprehensive help sections and clear FAQs. These allow players to find out the info they need or troubleshoot a problem by themselves if they prefer.

📋 How to create an account at an online casino

Signing up at a UK online casino is usually a quick and straightforward process, especially when registering with a licensed and reputable site, as you always should. That said, sometimes you can miss an important step or two and miss out on a key promotion, so here’s a short guide on how to ensure you’ll get everything right. Do note that these are general instructions, and some specifics, such as what the “sign up” button is called, may vary from site to site.

• Choose a licensed UK casino site – Start by picking a site regulated by the UK Gambling Commission. You can find our top-rated choices listed above to ensure you’re signing up for the best online casinos in the UK.
• Click on the “Sign Up” or “Join Now” button – Usually found at the top right or left of the homepage, this will take you to the new user registration form.
• Enter your personal details – You’ll need to provide your full name, date of birth, address, email, and phone number to comply with UKGC regulations, so expect to fill this info out on every UK-focused gambling site you sign up for.
• Create a username and password – Choose secure login credentials you’ll remember, and agree to the site’s terms and conditions. Remember not to use the same password twice, and especially try to avoid using the same or similar credentials on gambling sites that you’d use for other activities, such as your online banking account.
• Verify your identity – Most casinos will ask for photo ID and proof of address (such as a utility bill) to confirm your identity. This is part of mandatory KYC (Know Your Customer) checks and helps both you and the casino stay safe from bad actors and scammers.
• Opt in for the promotion and enter a bonus code (optional) – Casinos often have time-limited promotional offers that you can take advantage of by opting in and optionally entering a bonus code during the registration process. In some cases, simply registering an account and making your first deposit will be enough, but sometimes you’ll have to actively opt in and/or enter a promo code.
• Make your first deposit – Head to the cashier or banking section, choose a payment method, and fund your account. Make sure to read the promotion terms so you’re using only eligible payment methods here (e-wallets are often excluded) and your deposit is large enough to meet the requirements (typically £10 or more).
• Start playing – Once your account is verified and funded, you’re ready to start playing. If you’re trying to fulfil the conditions to get the bonus funds or free spins as part of the welcome offer, now is a good time to get familiar with the eligible games and any other terms & conditions you’ll need to fulfil. These can include potential time constraints or wagering requirements needed to unlock your bonuses.

🏆 Award-winning UK casino sites

Like any other thriving industry, gambling has its own awards ceremonies. There are a variety of respected organisations dedicated to naming the top online gambling operators. 

By way of patting ourselves on the back for spotting quality, we’re proud to say that most of our partner casinos have won awards. Here are a few of the accolades our recommended casinos have won in recent years:

• Online Casino of the Year 2024 - (Global Gaming awards)
• Digital Operator of the Year 2023 - (Global Gaming Awards)

• Online Casino Operator of the Year 2023 - (International Gaming Awards)
• Casino Operator of the Year 2024 (Bronze) - (EGR Operator Awards)

The best online casino software providers, as voted for by industry experts, work with our partner platforms, including Duelz, MrQ, and Virgin Games. Some of the notable winners are:

• Online Casino Supplier of the Year 2024 - Pragmatic Play (Global Gaming Awards)

👨‍⚖️ Why trust our casino reviews? 

Here at the Sun, our writers are not only experienced at their job but also passionate players and punters themselves. Each site we recommend is rigorously tested using our detailed Sun Factor methodology,  a structured evaluation system that focuses on key areas like licensing, security, game variety, user experience, and customer support. We aim to provide our readers with honest, clear insights to help them choose only the best online casinos the UK has to offer.

FAQ about casino sites in the UK

We get it - navigating online casinos can be a bit of a maze, especially if you’re new to the online gambling scene. That’s why we’ve rounded up answers to the questions we hear most often from our readers. Think of it as your no-nonsense guide to the stuff you actually want to know. 

1. Are casino sites legal in the UK?

Online casino gambling is legal in the UK as long as the platform in question is licensed by the Gambling Commission. The UK Gambling Commission (UKGC) is the official governing body of all gambling matters. From horse racing and poker to sports betting and casino games, the UKGC ensures the regulations, as defined by UK gambling law, are upheld by its licences. Therefore, as long as you use a UKGC-licensed online casino, such as Virgin Games, you can be confident it’s legal and safe. 

2. Can I use my credit card to play at an online casino? 

No, online gambling operators haven’t been able to accept credit card deposits since 2020. The was part of the government’s safer gambling reforms. Banning credit card deposits is designed to reduce the risk of people gambling with borrowed money. Debit card payments are still accepted at the best online casino sites, as are eWallets transactions from processors such as PayPal and Skrill.

3. What wagering requirements to expect at the best online casinos? 

The top casino bonuses have a wagering requirement (aka playthrough target) of 35x or lower. You’d need to bet £350 to clear a £10 bonus with a 35x wagering requirement. Clearing a bonus means you’ve converted it from site credit to cash that can be withdrawn. Any online casino bonus with a playthrough of 35x or lower is almost always claiming if you can do it responsibly. 

4. What online casino has the fastest payouts?

Duelz and Hot Streak Slots are two of the fastest payout online casinos in the UK. These popular online casinos typically process withdrawals within 1-2 days. The average payout time for UK online gambling sites is 3-5 days. Therefore, if you want your winnings in less time, it’s worth checking out Duelz and Hot Streak.
