The Best Mobile Casinos in the UK for May 2025

Looking for top-class online casinos that'll run like a dream on your mobile? We've listed the very best mobile casinos right here, all of which offer things like deposit matches and bonus funds to new players.

If you love gaming on the go, LeoVegas is your top choice! With an easy-to-use app and a superb collection of games, it’s no surprise it's one of the most popular mobile casinos in the UK. When I tried it on my mobile, it ran smoothly - just what you’d expect from a multi-award-winning casino. Whether you're on Android or iOS, LeoVegas works well on all devices.

I really enjoyed LeoVegas Exclusives and Originals, but you can also spin top slots like Book of Dead and Big Bad Wolf - anytime, anywhere!

More of a live dealer fan? Tap the Live Casino tab to enter the stunning real-time gaming lounge. Real human dealers here stream straight from legendary Las Vegas casinos like Bellagio and MGM Grand.

With over 2,500 real money slots now available on the casino’s updated native app, there’s never been a better time to try it out. And don’t miss out on a casino bonus or a live casino deal when you sign up. 

Some might tell you online mobile casinos are the future. But most casino gaming in the UK today is already taking place on smartphones and tablets. 

It’s not hard to see why. Mobile casinos give you access to thousands of games like slots, roulette and blackjack. Land-based casinos will always be special. But the best roulette sites and other mobile casinos make the excitement of playing for real money easier to enjoy.

Playing at mobile casinos isn’t exactly new, but the experience just keeps getting better.

More games are being fine-tuned for mobile, and sites are running smoother than ever on all kinds of screens. In fact, all the freshest names on the market take a mobile-first approach. 

The only real downside to playing at a mobile casino versus heading along to a local land-based establishment is the lack of social element. Plus you’ll need a reliable internet connection – but that’s run-of-the-mill stuff these days. All in all, it’s a small trade off.

That depends on you, and how you like to play. If you're the sort of person who'd love to dip into a few slots when you get a spare minute, you'll be delighted by the ease and convenience of mobile-ready sites. 

On the other hand, maybe you visit online casinos less often and prefer the big screen immersive experience on desktop. If so, mobile gaming probably isn't for you. 

Gaming on mobile or desktop is simply a matter of where, when, and how you like to play. These days, you'll find high-quality experiences on both platforms, each with its own strengths.

Nothing is stopping you from enjoying the best of both worlds. You can enjoy desktop iGaming at home and then switch to mobile play when out and about.

If you're still unsure, let's run through some pros an cons of playing via mobile.

Any casino worth your time and money will work on mobile. It’s standard across the industry these days, and frankly there’s no excuse for a site to fall at this hurdle in 2025. But that’s a pretty low bar all things considered, and you won’t be surprised to hear that not all mobile casino sites are created equal. 

So what separates the good from the bad? The sites better left alone from the best UK mobile casinos in the business? Here are just a few criteria we always look at.

The best casinos won't just run smoothly on your smartphone, but work like a dream on tablets, notebooks, and even smart watches too. From Apple and Samsung to Huawei, Sony, Nokia, and Google, a quality site should cover the spectrum. Casumo Casino is one site that's knocking it out of the park in this regard. 

The development of HTML 5 has allowed casinos to create a high-quality experience on mobile. So much so, in fact, that playing on mobile or tablet these days is just as good as on desktop, with the only difference being the size of the screen. Just take Griffon Casino as one example. 

You'll soon know which casinos treat mobile as an afterthought. Just look at their mobile-friendly games libraries. Top mobile casinos have hundreds of slot, table and live dealer games that perfect perfect for playing on your phone.

Mobile casino sites should keep things simple, from quick sign-up and many casino payment options to easy withdrawals.

Taking all that and many more factors into account, we’ve settled on these few as the best mobile casino sites.

All the above taken into account and then some, we're ready to call it. 

From new to established casinos that are always tweaking their offering, we never sit still, and our lists are always changing. But as it stands here today, here's our podium finishers for the best mobile casinos in the UK.

If you’re firmly on team Apple, you’ll need mobile casino sites built with the iOS platform in mind. This operating system comes on all the company's devices, including the iPhone, iPad, and Apple Watch. 

Given how popular Apple’s kit is, most mobile casinos are tested rigorously to ensure the experience on iOS is a great one. And with plenty of Apple fans among our own ranks, we were able to find one that really stood out. 

That would be TonyBet Casino. With north of 4,000 games to choose from - all fully optimised for mobile - there's plenty here to keep you busy. The dedicated iOS app is super speedy and east to navigate, and overall you just get a premium experience when you call in here. They're pretty generous with their bonuses too, just like the one below. 

Android is the bigger beast. You’ll find it on devices from brands like Samsung, Google, and OnePlus.

If a mobile casino can’t get it right here, it begs the question of where they can get it right. Thankfully, most of the casinos we come across comfortably pass the smell test, but some really do go that bit extra. We found this one in particular to be the best mobile casino in the UK when using Android. 

The MrQ Casino app for Android is impressive. It’s easy to navigate and looks great right from the start. Once you dive in, you’ll find hundreds of games. Most of them are slots, which makes it perfect for playing on your phone.

What's particularly impressive is that MrQ fits in more than 80 live games for mobile. If that wasn't enough, they're often running epic bonuses for new players. 

While these are our best sites for iOS and Android right now, there are plenty more top-class examples out there. In fact, any half-decent casino will be working tirelessly to ensure the experience on any and all mobile devices is a good one. 

We always check for this, and if playing on mobile didn't live up to expectations somewhere, you wouldn't find it listed on our site. 

So we've told you which casinos we'd go for right now, but don't just take our word for it. Whether you already had a mobile site in mind, it makes total sense to compare. 

Our Casino Comparison tool lets you do just that. It allows you to weigh up the attributes of three different sites. Just click below to get things started.

Once you've found a casino you're happy to play at, it's time to turn all the attention to gameplay. Sure, almost every site we list here will cover all the bases. But just like anything in life, some simply do better than others.

Which UK site has the most mobile games out there? Which online casinos knock it out of the park for slots, table classics, and live dealer games? Let's find out. 

Quality over quantity, the old saying goes. But from our experience, a hefty game selection is always a sign you’re playing in the right place. Especially when those titles are perfectly optimised to work on mobile. 

To use another phrase, variety is the spice of life. If you're going to sign up for a new mobile casino, it's only natural to expect an exciting selection of games. 

Whether you like online baccarat or bingo, it's always great to find UK mobile casinos with something for everyone. 

On that note, we’ve crunched the numbers and ranked the top mobile casinos by the size and scale of their games library. Here’s a look at who came out in front. 

If you’re playing at a quality site, you should find as many games available on mobile as you would expect on a desktop or even at a land-based casino. 

Software developers have found inventive ways to bring almost every casino classic to our phones. Meanwhile, the latest games are always built with mobile gaming in mind.

So whether you play poker online or progressive jackpot slots are more your bag, you can expect the same slick experience you’re used to. Especially when you choose one of the licensed sites we list on Casinos.com. 

We expect to see upwards of 80% of a casino’s games available on mobile, and we’re very happy this is a benchmark most mobile online casinos are now meeting. 

Now that the lobbies of UK mobile casinos are packed to the rafters, you’ve an even tougher call in picking a game to play. Some sites will have thousands of titles, so how can you tell which games are worth your time and money?

Slot games are the bread and butter of the mobile casino world. That’s hardly surprising given how well these games lend themselves to playing on the go. Most involve a simple spin to play, with graphics and animations that are a tidy fit for our phone and tablet screens. 

Plus, unlike many other casino games, you can dip in and out of slots within seconds. The result is that you can play mobile slots pretty much anywhere – riding the bus or in a waiting room. Whenever you get a moment to yourself, basically. 

If you’re not on board already, online casino free spins might sweeten the deal. Tons of sites dish these out to new players in their welcome packages, and some of those casinos continue to hand them out to players who stick around. 

For sheer number of slots combined with overall site quality, Casumo is one of the best UK slot sites we could find. There are more than 2,000 slots titles available on mobile, and their sign up bonuses always include some free spins on the most popular slot games. 

It’s been much more difficult to adapt table classics for mobile. The clue is in the name. These games are designed around a live setting where you share a table with your fellow players. And yet, new mobile casinos in the UK have found the answer. 

Today, many online roulette and blackjack casino sites offer random and exciting games. All thanks to inventive software providers.

These popular casino games look great on smaller screens, and good sites offer different ways to play and bet. The only thing some players may find lacking here is the lack of interactive element – you’ll be playing against the computer. If that doesn’t sit right with you - why not try live casino? 

For table games on mobile, you'll struggle to find better than BetVictor. A household name in gambling, its online casino is every bit as good as its sports betting these days. That's particularly true of its epic table games segment. Both its iOS and Android apps - as you'd expect from such a big brand - are top quality. 

If you love an authentic casino experience, live mobile casino is the stuff of dreams. The latest software at the top live casinos lets you place real-time bets on classics like blackjack and roulette. It also lets you try recent hits like gameshows and live bingo rooms. 

To play, find a title and room you like the look of, then join and wait to enter. Once the game starts, you can see and hear the dealer. You'll have full sight of what’s happening in the room or on the table, with playing options available on screen.

It’s the closest you can get to the thrill of a land-based casino without being there – all from the convenience of your mobile. 

If that sounds right up your street, give Mr Vegas a whirl. With over 200 mobile-friendly titles, you can enjoy baccarat, roulette, gameshows, and live bingo. And don't forget to use this new player bonus when you do.

As new games are released every week, finding the best mobile casino games can be tough. There's no one game we can point you to and promise an unrivalled game experience with maximum odds of winning. But there are a few key things that you can clock when exploring the games lobby.

This is the percentage of the money wagered that a game will end up paying back to players over time. The higher the percentage, the more it pays back, but it’ll always be below 100% since casinos do expect to make money. 

Generally, anything over 96% is deemed to be pretty good. But the best games, usually live casino games like blackjack, are upwards of 98%. Meanwhile even the best online slots for real money tend to have the lowest RTP but do offer a chance of winning huge from a small bet. And that’s always thrilling to play.

Here's one game offering mega-high RTP right now: 

n these games, the jackpot keeps growing as more people place bets without anyone winning. Then, when the jackpot drops, one lucky player hits it big with a massive payout!

Unlike games such as poker, a progressive jackpot does not require skill; it is all about sheer luck. This is exciting, given that the biggest progressive jackpot games offer millions of pounds in prizes.

As far as progressive jackpots go, they don’t get much bigger than this: 

In an area of the industry that’s booming, it’s no surprise that developers are dropping new mobile casino titles all the time. In fact, almost all the latest casino games are being built for mobile since that’s where most people choose to play these days. In other words, if it’s a recent release, you can be confident it will run smoothly on all your devices.

If you’re well versed in the world of mobile casino and need a new game to try, we can’t recommend these newly dropped titles enough. But even if you’re a newcomer, slot games like these are nice and easy to get the hang of. 

Fresh games drop by the week, so don't forget to check back here whenever you're ready to try something new. We also keep a keen eye out for any brand new online casinos, so check our dedicated page for any sites you might have missed.

Given the wholesale shift towards mobile gaming, many top UK mobile casino sites have built their own bespoke app.

Some of them have been knocking about for years already. Meanwhile, players with a keen eye may always see new platforms dropping into their relevant stores. So, is this something that gives these casinos on mobile the edge? 

Our answer? Not really. Sure, it’s always great to see a casino put effort into constructing a slick and well-optimised app. But it’s not essential. Any quality mobile casino will have a browser site that runs almost as well as even the best casino apps. If the experience in your browser is poor, that’s a surefire sign you’re playing in the wrong place to begin with. 

While the experience should be somewhat similar, there are a few differences. Mobile browsers always need an internet connection. But apps work offline (e.g. free games). And sometimes apps can be a tad smoother with no lags at all.

On the flip side, you don’t have to download anything when you play in your browser. Plus, there are more casinos on mobile sites, and you often get a bigger selection of games, even if an online casino offers both options.

Getting up and running at a casino for mobile shouldn’t be any hassle – not if you’re in the right place. In fact, the hardest part of all is choosing which site to play at. 

We’ve listed plenty for you above, all of which are licensed sites that meet all our marks for quality. They also all offer a welcome bung to new players. And you might find the best online casino bonus in the UK here. 

Once you’ve chosen, click the link to begin the signup process. It only usually takes a matter of minutes. After that, all that’s left to do is deposit and play.

The best sites, lik PayPal casinos offer a bunch of different payment options. You can use popular methods like Maestro and Visa or e-wallets. But since you’ve already got your mobile, you may find a pay by phone casino super handy. 

Once the funds have landed, you’re ready to head to the lobby and let the fun begin. 

If you’re new to casino sites altogether, here’s a clearer rundown of how things work. 

Step 1: Choose a mobile casino – All of those we list here are high quality, legit, licensed sites. 

Step 2: Get set up with an account – Follow the steps to complete your registration. You’ll need to provide things like your name, date of birth, and address, as well as choosing a username and password. 

Step 3: Claim your bonus – Casino bonuses are available to new players and are usually added automatically. Always check the promos area of your account as you may need to enter a code to claim it. 

Step 4: Deposit and play – Choose a payment method and put funds into your account. This will usually be required to unlock the bonus. Then head to the games library and let the fun begin.
