Casumo slots app

Does Casumo have a slots app in the UK?

Yes. Casumo publishes an app for iPhone and iPad through Apple’s App Store and an Android app through Google Play, and both are available to UK players. The two listings are not identical: the iOS title, Casumo Casino & Sports Betting, bundles the casino and the sportsbook in one download, while the Android title, Casumo - Live Casino & Slots, is presented as a casino app. Either way, the app logs into the same account you would use on the Casumo casino website, with the same balance, limits and game lobby.

What the app does not do is change the games. A slot such as Big Bass Bonanza or Starburst runs on the developer’s server and is streamed to whatever screen you use, so its RTP, paytable and random number generator are the same in an app, a mobile browser or on a laptop. Game availability changes, so search the lobby for any title you want rather than assuming it is there.

The app store pages are the source for the details on this page (app names, size, iOS version, age ratings and listed features). Store listings change with each update, so check the current listing before you download.

Casumo app on iPhone and Android: the store details

The table below sets the two listings side by side. Where a store does not publish something, it says so rather than guessing.

The iOS listing notes that the Mac version is “Designed for iPad” and not verified for macOS, so on a Mac the website is the more predictable option. The Google Play listing’s PEGI 18 rating also flags in-game purchases, which is the store’s standard label for any real-money gambling app rather than a separate feature.

How to install the Casumo app and get to the slots

Installing takes a few minutes. The steps are the same in spirit on both platforms; the only difference is which store you open.

1. Open the App Store (iPhone or iPad) or Google Play (Android) and search for Casumo. Check the developer name matches the listing shown above before installing.
2. Install the app and open it. On iOS, make sure the device runs iOS 15.0 or later first.
3. Log in with your existing Casumo details, or register a new account. New accounts are age- and identity-checked before you can deposit or play, including demo games.
4. On iPhone, turn on Face ID or Touch ID login if you want quicker access; the store listing says both are supported.
5. Set a deposit limit when prompted. Since 31 October 2025, UK operators must ask you to set a financial limit before your first deposit.
6. Open the casino lobby, search for a slot, read its help screen and set your stake before the first spin.

What the Casumo slots app adds over the mobile website

The App Store listing names several features that are about convenience. None of them changes a slot’s maths, but some change how quickly you can get back into a game, which is worth thinking about honestly.

Two of these deserve a plain comment. Reel Races are timed slot competitions; how prizes are decided is set out in the race rules, and our explainer on whether slot tournaments work covers how this kind of competition is usually scored. The Adventure is a levelling system that moves as you play; a higher level reflects how much has been staked, not any skill, and the house edge still applies to every spin along the way.

Playing slots in the Casumo app: what changes and what does not

A slot on a phone screen looks different, but the machine underneath is the same. The developer’s server runs the RNG, picks the reel positions and works out the payout before the reels on your screen stop. The app simply draws the result. That is why a slot’s RTP is the same on any device and why tapping the screen at a particular moment makes no difference, a point covered in can you stop a slot spin early.

UK rules apply in the app too

• No autoplay: each spin has to be started individually (autoplay ban, since 31 October 2021).
• At least 2.5 seconds per spin, and no turbo or slam-stop buttons (2.5 second spin rule).
• Stake caps of £5 per spin for players aged 25 and over and £2 per spin for players aged 18 to 24 (online slot stake limits).
• No celebration of a return that is equal to or less than your stake, and your net position and time played shown on screen.
• No feature-buy option: slots supplied to Great Britain don’t sell entry to the bonus round.

Small-screen practicalities

Portrait mode suits simple 5×3 games; wide grids and Megaways slot machines are often easier to read in landscape. If your connection drops mid-spin, the result was already decided on the server and is normally settled to your balance when you reconnect, as explained in what happens if your connection drops mid-spin.

Does the Casumo app pay out more? The maths on mobile

No. Return to player is fixed in the game version supplied to the casino, not in the app. What the app can change is how many spins you get through, because quicker logins and deposits remove friction. Here is what that means in pounds for a 96% RTP slot.

At the 2.5-second minimum, 300 spins take at least 12.5 minutes, and in practice longer once features play out. The figures are averages across millions of spins; a single session can end well above or well below them, and high-volatility games swing hardest. Our page on how much a slot costs per hour works through more stake levels.

Casumo app privacy labels and data

Both stores require developers to declare what data an app collects. The App Store privacy label for the Casumo app lists identifiers, usage data and diagnostics as data that may be used to track you, and financial information, contact information, user content, identifiers, usage data and diagnostics as data linked to you. Google Play’s data safety section says the app may share location data, collects personal and financial information, encrypts data in transit and lets you request deletion.

Location data matters for gambling apps because licensed operators need to know where a customer is playing from. Read the current labels on the store page before installing, and review the permissions the app asks for in your phone’s settings afterwards; you can decline optional tracking requests when they appear.

Casumo app or mobile browser: which suits you?

If you only play occasionally, the mobile website in Safari or Chrome does the same job with nothing installed. Our mobile slots guide and slot apps guide compare the two approaches across casinos.

Setting limits inside the Casumo slots app

The limits you set apply to your account, so a deposit limit added on the website also binds the app and the other way round. UK rules require operators to let you set limits in free text rather than choosing from suggested amounts, and a reduction in a limit takes effect straight away; an increase usually has a waiting period. A time-out or self-exclusion set on one device covers every device on that account.

Casumo is also covered by GAMSTOP (opens in a new tab), the national online self-exclusion scheme every UK-licensed online operator must take part in. For the full set of options, see the Casumo safer gambling tools page.

Casumo app support and troubleshooting

Casumo’s UK homepage (opens in a new tab) publishes an email address, hey@casumo.com, and UK support hours of 7:00 to 23:00 (UK time). It does not publish a phone number on the page we used as a source, and live chat details are not listed there, so use the help section inside the app for the current contact options.

• App will not install: check the iOS version (15.0 or later) and free storage.
• Can’t log in after an update: update the app from the store, then try password reset on the website.
• Deposit refused: credit cards cannot be used to gamble in Great Britain, and an e-wallet topped up with a credit card is also off limits.
• Slot will not load: close and reopen the game; if a spin was in progress, check the game history before contacting support.

Casumo app offers and where to play

Casumo’s welcome offer works the same whether you join through the app or the website: 18+, new customers, opt-in required, 50% bonus up to £100 on a first deposit of at least £20. The bonus must be wagered 10x within 7 days, with a maximum of £5 per bet while it is active, and game, play and payment restrictions apply. On a £20 deposit that is a £10 bonus and £100 of wagering; on a £200 deposit it is the full £100 bonus and £1,000 of wagering. More detail is on the Casumo slot bonus page.

The second box below is PlayOJO, whose offer is 80 free spins on Big Bass Bonanza with a first deposit of £10 or more (new UK customers excluding Northern Ireland, 18+), each spin worth 10p, with no wagering on winnings. Game availability changes at every casino, terms apply, and gambling should only ever be paid for from money you can afford to lose.

18+. Gambling should be entertainment that costs money, not a way to make it. Decide a budget before you play: plan a slot budget. Free, confidential help: National Gambling Helpline 0808 8020 133.
