Android App and iPhone Web App: What Is the Difference
On Android, Slotonauts comes as an APK file. You download it from the site and install it like any other app, and its icon appears in your app list.
On iPhone, the site works as a web app (PWA). You add it to the home screen through Safari, and it opens like an app, without the App Store and without a separate download. In both cases you use the same account, the same balance and the same bonuses as on the website.
What You Get on Your Phone
The app is not a cut-down version. On your phone you get:
- the full casino lobby with slots, jackpots, Hold and Win and crash games;
- the live casino with roulette, blackjack, baccarat and poker;
- the sportsbook and the Cybersport section with live betting;
- promotions, missions and your VIP progress;
- the Cashbox for deposits and withdrawals;
- the Online Chat with support.
With notifications turned on, you also hear about new bonuses and tournaments as soon as they start.
How to Install on Android
Installing the APK takes six short steps:
- Open the site on your phone and go to the menu, then App.

- Expand How to install for Android.

- Press Download. The download starts right away.

- Open the file from your Downloads folder.
- If the system asks, allow installation from unknown sources, then install the app.
- Turn on notifications. This is a condition for the install bonus.
How to Add the App on iPhone
On iPhone, everything happens in Safari:
- Open the site in Safari, go to the menu, then App, and expand How to install for iOS.

- Tap the Share icon, the square with an arrow, in the toolbar.
- Scroll down and choose Add to Home Screen.
- Tap Add to confirm.
- Find the Slotonauts icon on your home screen.
- Turn on notifications to get the bonus.
Downloading With a QR Code
If you open the App page on a computer, you will see two options: the Download link and a QR code. Point your phone camera at the code, open the link and continue the installation on your phone.
Bonus up to 50 € for Installing
The size of the install bonus depends on how much you deposit:
| Deposit | Bonus |
|---|---|
| From 1 € | 5 € |
| From 51 € | 10 € |
| From 101 € | 15 € |
| From 251 € | 20 € |
| From 501 € | 30 € |
| From 1001 € | 50 € |
To receive it:
- make a deposit from 1 € before installing or within 72 hours after;
- turn on notifications for the app;
- remember that the bonus is given once.
The app bonus works alongside the other Slotonauts bonuses, from the welcome package to weekly cashback.
Signing Up and Logging In on Mobile
Registration in the app works the same as on the site: an e-mail and a password, or one tap with Google, Telegram or X. If you already have an account, simply log in with the same details. The welcome package of 375% up to 3000 € + 300 FS is available in the app too.

Games and Betting in the App
Some games feel especially natural on a phone: slots and Hold and Win titles, quick crash rounds, live roulette and in-play bets during a match. In the mobile version, a tab bar at the bottom of the screen keeps four buttons close: Games, Sport, Sign up and Promotions. From there, the full casino games lobby is one tap away.
Mobile Payments
The Cashbox is the same as on the website. Apple Pay and Google Pay are the quickest options on a phone, and you can also pay with Visa, Mastercard, Monzo, Revolut, Starling Bank or crypto. Withdrawals go through the Cashbox too, are usually processed in 24-36 hours, and their status is shown in Withdrawal history.
Staying Safe on Mobile
A few habits keep your account protected:
- download the APK only with the Download button on the official site, never from other sources;
- lock your phone screen with a PIN, fingerprint or face recognition;
- log out if you play on someone else's phone.
The site itself runs over SSL.
Installation Problems and Fixes
If something goes wrong, the fix is usually simple:
| Problem | What to do |
|---|---|
| Android blocks the installation | Allow installation from unknown sources when the system asks |
| No Add to Home Screen option | Open the site in Safari, not in another browser |
| The bonus has not arrived | Turn on notifications and check that you deposited within 72 hours |
| Cannot find the file | Look in the Downloads folder |
