UK mobile casinos are booming—but not every app deserves a place on your home screen.
Today, nearly 60% of all UK online gambling happens on mobile devices, which means casino apps have leapfrogged desktop sites and mobile browsers to become the go-to platform for real players in 2025. And it’s not just about being able to bet from your sofa. For millions, a great mobile slots app unlocks genuine flexibility—spinning the reels while commuting, cashing in exclusive in-app bonuses, or jumping straight into a table game in seconds.
he numbers paint a clear picture: as of 2025, there are around 4.5 million active UK accounts playing digital slots every month. Even more staggering, mobile-focused platforms are now delivering over 23 billion spins in a single quarter. That’s how central mobile apps are for casino fans across the country. Why? Players want speed, simplicity, and exclusive perks that sites alone can’t match—and UK casino operators have responded with apps designed for seamless gameplay, rapid cashouts, and bigger, better promotions.
Sure, forums like Reddit and Quora love to debate which casino apps to trust—but the advice often lags behind or misses key safety factors. Here at OffersBet, our team tests and updates every UK casino app featured for 2025. We prefer sites with a dedicated iOS and Android app rather than those that are merely mobile optimised. This is reflected in the ratings that we give.
But it doesn’t stop at just having an app. The best UK casino apps go further: large games libraries, good-value bonuses, and must-have features that make each spin or hand truly worthwhile. Ready to find out who’s really at the top in 2025? Check out our expert picks—like bet365, Grosvenor, and 10bet—on our list of the UK’s top online mobile casino options for this year.
The Best Casino Apps and Mobile Casinos in the UK
1: Bet365: The Top-rated Casino App
Welcome Bonus: Many days of free spins when you make an initial deposit of £10 or more
Apple Store Rating: ⭐️4.5/5.0 (16,800 ratings)
Google Play Rating: ⭐️4.1/5.0 (3,600 ratings)
Our Editor’s View: “Bet365 is by far the best mobile casino app in the UK, with impressive ratings among iOS and Android users. All its slots, table games, and live dealer titles work well on the app, but you can also sign in to play Bet365 games directly on a mobile browser. My only peeve with Bet365 is that the live chat via the app isn’t great. If you have an issue, it’s better to email the customer support team directly.”
Pros & Cons
| Pros | Cons |
| ✅Top rated app for iOS and Android | ❌Limited customer support |
| ✅Thousands of games from top studios | |
| ✅Superb sportsbook alongside the casino |
2: 10bet Casino: The Best Mobile Casino App for Game Variety
Welcome Bonus: Frst deposit bonus up to £50
Apple Store Rating: ⭐️3.0/5.0 (82 ratings)
Google Play Rating: ⭐️2.7/5.0 (231 ratings)
Our Editor’s View: “10bet is one of my go-to mobile casino apps thanks to its huge game offering, with over 2,000 titles to keep things interesting. Slots, table games, and live dealer titles are available via the iOS and Android apps from studios like NetEnt, Playtech, and Pragmatic Play. That said, 10bet doesn’t have the greatest welcome package right now, and the 50x wagering will likely put off low-budget players.”
Pros & Cons
| Pros | Cons |
| ✅Brilliant game selection and variety | ❌High wagering on the welcome bonus (50x) |
| ✅Decent line-up of crash games | |
| ✅Top class live casino offering |
3: Grosvenor Casino: Our Favourite App for Live Casino Games
Welcome Bonus: Deposit £20 or more for a £30 welcome bonus + 100 Free Spins
Apple Store Rating: ⭐️4.2/5.0 (12,800 ratings)
Google Play Rating: ⭐️2.7/5.0 (1,230 ratings)
Our Editor’s View: “Grosvenor is all about the live casino, with an incredible offering of unique and exclusive live dealer table games streamed from various Grosvenor locations in the UK. The app, particularly on iOS, is one of the best in the UK, and Grosvenor always has some decent ongoing rewards for all players. The main downside is that the welcome bonus is capped at wins of £2,000, so if you land a big win, you might not be able to cash out entirely.”
Pros & Cons
| Pros | Cons |
| ✅Highly rated iOS app | ❌Welcome bonus wins capped at £2,000 |
| ✅Exclusive live casino games | |
| ✅Engaging higher or lower ongoing rewards |
4: Monopoly Casino: Best Mobile Casino App for Branded Slots Fans
Welcome Bonus: Get £50 of free bonuses when you play £10
Apple Store Rating: ⭐️4.6/5.0 (14,300 ratings)
Google Play Rating: ⭐️4.2/5.0 (4,900 ratings)
Our Editor’s View: “Monopoly Casino is a strong choice for anyone who loves branded games and instant wins. The app stands out because of its exclusive Monopoly-themed slots and table games that aren’t available elsewhere, backed by Gamesys. The user experience is seamless on both Android and iOS, and the £50 bonus for a £10 stake is excellent value. However, you won’t find many traditional slot providers here like Pragmatic or NetEnt, which might be a drawback for some players.”
Pros & Cons
| Pros | Cons |
|---|---|
| ✅Unique Monopoly-themed games | ❌Lacks variety of external game studios |
| ✅Easy-to-use, well-reviewed app | ❌Limited live casino options |
| ✅Strong welcome offer with low entry |
5: Virgin Games: Best UK Casino App for Daily Free Games
Welcome Bonus: £50 bonus when you stake £10
Apple Store Rating: ⭐️4.7/5.0 (16,900 ratings)
Google Play Rating: ⭐️4.3/5.0 (6,000 ratings)
Our Editor’s View: “Virgin Games continues to be one of the most loved mobile casino apps in the UK, and it’s easy to see why. From daily free games with cash prizes to a fantastic selection of slots and instant win games, the app offers value and variety. I especially like the loyalty features and daily prize wheels. But don’t expect a massive library of third-party games—it’s more about curated quality than quantity.”
Pros & Cons
| Pros | Cons |
|---|---|
| ✅Daily free games and prize wheels | ❌Fewer game studios than some rivals |
| ✅Excellent mobile app design | ❌Limited game filtering/search tools |
| ✅Strong brand trust and reputation |
6: Mr Play: The Top Online Mobile Casino for Free Spins
Welcome Bonus: 100 spins + £200 in bonus cash
Apple Store Rating: ⭐️5.0/5.0 (unspecified)
Google Play Rating: ⭐️2.2/5.0 (147 reviews)
Our Editor’s View: “Mr Play has long been a top online casino in the UK, and if you download the iOS or Android app today, you can access up to 100 free spins and £200 in bonus cash as a new player. As such, it’s my number one recommendation for free spins. The app is extremely well-designed and easy to navigate, with over 1,000 games. Just be mindful that Mr Play’s payouts can take 3-5 days on average, longer than most of the fast-payout online casinos in the UK market.”
Pros & Cons
| Pros | Cons |
| ✅Modern & sleek casino design on mobile | ❌Not the fastest casino app for payouts |
| ✅Over 1,000 games | |
| ✅Numerous ongoing promotions |
7: Midnite Casino: Ideal iOS Casino App for Ongoing Promotions
Welcome Bonus: Deposit and wager £20 for 100 free spins
Apple Store Rating: ⭐️4.6/5.0 (1,400 ratings)
Google Play Rating: Not available
Our Editor’s View: “If you’re searching for a newly-released online mobile casino, Midnite fits the bill. Launched in 2023, the app is home to over 1,700 brilliant casino games, and if you sign up and deposit £20, you can access 100 free spins and a heap of good-value ongoing promotions. On the flip side, the Midnite Casino app is currently only available to iOS users. If you have an Android phone, you can log into your Midnite Casino account via Chrome or any other mobile browser.”
Pros & Cons
| Pros | Cons |
| ✅Excellent ongoing promotions | ❌No Android app |
| ✅Highly rated iOS casino app | |
| ✅Over 1,000 top-rated slots |
8: William Hill Vegas: Top-Rated App for Playtech Slots and Jackpots
Welcome Bonus: Bet £10, Get 50 Free Spins (no wagering)
Apple Store Rating: ⭐️4.6/5.0 (9,800 ratings)
Google Play Rating: ⭐️4.1/5.0 (4,300 ratings)
Our Editor’s View: “William Hill Vegas is ideal for fans of high-quality slot games and progressive jackpots, especially from Playtech. The Vegas-branded app is separate from the main William Hill sportsbook app, giving players a focused casino experience with fast loading times and sleek navigation. I like that the welcome offer has no wagering requirements, which is rare. However, the Vegas app doesn’t carry all of William Hill’s games—you’ll need to use the main app for live casino and some specialty games.”
Pros & Cons
| Pros | Cons |
|---|---|
| ✅No wagering on welcome spins | ❌Live casino not included in the Vegas app |
| ✅Strong Playtech jackpot selection | ❌Fewer promotions than main WH app |
| ✅Well-optimized standalone casino app |

Main Features of the Best Casino Apps and Mobile Casinos
Now that we’ve introduced you to the best casino apps and mobile casinos in the UK, we want to provide you with a checklist to help you identify other top-rated apps and platforms.
If you take your research into your own hands, here are the key features to look for when deciding whether to download a mobile casino app:
App Rating
Start by visiting the Apple or Google Play Store, depending on your operating system, and see the casino’s rating.
The better the reviews from verified users, the better the app will be when you download it. Spend a few minutes reading through the latest reviews for a good idea of what to expect when you download and play.
Mobile-Ready Slots and Game Variety
The best casino apps and mobile casinos offer at least 1,000 games from dozens of studios, including Evolution, Pragmatic Play, NetEnt, and Playtech.
Small game lobbies lack variety, and you should avoid sites that only host games from unknown studios. Before signing up, check that the casino offers fresh mobile slots, table games, and live dealer games, and use the search bar provided to find your favourite titles.
Bonus Size & Terms
Practically every online mobile casino offers promotions, so you need to consider its size, terms, and conditions before triggering it.
We expect a welcome bonus with bonus cash or free spins and give the best ratings to mobile apps with low wagering requirements (20x or lower). You should also check the timeframe, including how long you have to satisfy the requirements before cashing out.
Our editor on casino app bonuses: “It often pays to download a casino’s mobile app, as many platforms offer unique and exclusive promotions to mobile users. For the latest mobile bonuses in the UK, check our exclusive casino promo codes before downloading an app from the Apple or Google Play Stores.”
Payment Options
One of the most attractive things about downloading a mobile casino app is the option to transact with Apple Pay or Google Pay. This is perhaps the most convenient way to deposit and withdraw online casino funds, and it is the reason for downloading an app alone.
You should also consider which other payment methods the casino supports (e-wallets, debit cards, etc) and check how long it takes for the casino to pay your winnings. Ideally, the casino app should offer instant deposits and withdrawals within 1-3 days.
The Benefits of Mobile Casino Apps
Why should you choose an online mobile casino over a standard site? Well, there are numerous benefits to playing games via dedicated apps, including:
✅Unlimited gameplay: The convenience of a mobile app is second to none. You can access your mobile casino account anytime, anywhere, whether on the tube or in the staff room on your lunch break.
✅Exclusive offers: Casino app users can often access exclusive promotions that aren’t available to other casino customers. These promotions are advertised directly on the app; you can access them whenever you play your favourite games.
✅Optimised gaming: Though you can play casino games on a mobile browser without downloading an app, doing so ensures optimised gaming and the best possible gambling experience. Expect top-quality graphics, short load times, and excellent gameplay when you play on your smartphone.
✅Excellent customer support: The best casino apps and mobile casinos offer excellent customer support via the app, usually in the form of 24/7 live chat. You may also have the option to complete KYC checks via the app, which is much more convenient than sending them via email.
From our editor and app reviewer:
Why I Prefer Mobile Casinos Over Desktop
Having tested dozens of UK casino apps, I genuinely prefer playing on my phone rather than desktop. For example, when I played slots like Big Bass Bonanza on Bet365’s app, it loaded noticeably faster than the desktop version. I can easily switch between games like roulette or blackjack during my daily commute, and depositing instantly with Apple Pay is far more convenient than entering card details manually on desktop.
Casino App Sign-Up Offers Worth Claiming
I’ve claimed multiple sign-up offers across different UK casino apps, and some stood out clearly from the rest. For instance, Mr Play’s welcome offer—500 free spins and £200 bonus cash—is one of the best I’ve encountered, especially since the wagering terms are clear and fair. Bet365’s “20 days of 500 spins” promo is another excellent deal, allowing me to explore different games each day without additional deposits.
Mobile Slots That I Keep Coming Back To
From personal experience, mobile slots are my favourite for quick entertainment. Games like Starburst on 10bet’s app or Pragmatic Play’s Wolf Gold at Midnite Casino load seamlessly on my phone and always run smoothly, even on a weaker Wi-Fi connection. Plus, many mobile casinos regularly offer boosted winnings or free spins on popular slots, making mobile gameplay even more rewarding.
Discover the best casino apps and mobile casinos in the UK in 2025, such as Grosvenor, 10bet, bet365 Games app, Mr Play mobile-ready casino. Sign up for the top-rated online mobile casinos via Offersbet for new slots, promos, game variety, and more.
Here are some of the best new UK mobile sites: Midnite Casino, Gentlemen Jim app, Betrino Casino, NRG Mobile, PricedUp app. Among the top favourites are bet365 (free spins sign-up promo), Grosvenor, 10bet (best app), and MrPlay (perfect slots mobile operator). Another app for real money games we recommend is Vic Mobile Casino.
