Identifying the best casino apps and mobile casinos is essential if you want to play slots, table games, and live dealer titles on your smartphone or tablet.
At OffersBet 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.
However, a mobile casino app should also offer many games, good-value bonuses, and other features to achieve a top score. So, join us as we introduce you to the UK’s top online mobile casino options this year: bet365, Grosvenor app, and 10bet are among the top ones.
The Best Casino Apps and Mobile Casinos in the UK
1: Bet365: The Top-rated Casino App
Welcome Bonus: 10 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: 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 |
3: 10bet Casino: The Best Mobile Casino App for Game Variety
Welcome Bonus: 50% first deposit bonus up to £250
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 |
4: Grosvenor Casino: Our Favourite App for Live Casino Games
Welcome Bonus: Deposit £20 or more for a £30 welcome bonus
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 |
5: 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 |

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 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—100 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 “10 days of free 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.
