21bit Casino keeps the Android route short: one file, one permission, then your account.
Finish the file before you tap
Tap the Android download button on this page and let the 47 MB file finish before you touch it. Watching the progress bar to the end prevents a truncated package.
Browser install permission
Open Settings and allow your browser to install unknown apps for this one session. Turning the switch off again once the install completes is the tidiest habit.
Right after the prompt
Confirm the install prompt and wait for the app icon to appear on your home screen. If nothing shows after a minute, open your downloads list and run the file from there.
Same email, same account?
Launch the app and sign in with the email address tied to your existing 21bit Casino account. One account covers the app, the browser and the web app, so nothing needs setting up again.
Why install at all
21bit Casino app versus a saved tab
Settles whether the extra icon earns its place on a phone already full of them.
Tables made for a thumb, not a cursor
Open a live table wherever you are and play it in the app's own full-screen layout, drawn from the same 4,879-title floor as desktop, with no pinch-and-zoom fiddling.
Cashier built into the tap flow
Top up through Visa, Mastercard, Skrill, Neteller, Apple Pay, Google Pay, PayID or POLi without leaving the app, with deposits from A$12 and withdrawals from 27.
Is my old login still good?
Reach your existing account with the email address you registered, because app, browser and web app share one login and one set of credentials.
Browse the full 4,879 on a tram
Scroll 4,879 titles from 101 providers in a layout made for touch, so the catalogue you know on desktop arrives sorted rather than shrunk.
21bit Casino on iOS
Does 21bit Casino work on iPhone?
Nothing gets bypassed here: the iPhone route runs through Apple's own store.
Store listing, not a lookalike
Open the App Store on your iPhone and search for 21bit Casino, checking that the listing shows version 4.8.2. Ignoring similarly named entries keeps you with the casino itself.
Will it stall mid-way?
Tap Get and let the 47 MB download run over a steady connection. Keeping the screen awake until the icon lands avoids a stalled transfer.
Already signed in elsewhere?
Sign in with the email address and password you already use on the computer. Your session, balance and bonuses follow the account rather than the device.
Alerts you can switch on
Allow notifications when the prompt appears, and the app can tell you about withdrawals and bonuses. Declining costs you nothing and the setting stays open in iOS at any time.
Stuck partway through
From dead icon to a running app
Gives you a likely cause and two concrete moves for each stall, before you contact support.
Tapping the icon does nothing
A crash within seconds of tapping the icon usually means a half-finished update or a cached file left behind, so the splash screen never clears.
Force-stop the app and reopen it
Delete the app, then install 4.8.2 again
Password refused, access restored
A rejected password points at a mismatch rather than a broken app, because the login screen checks the email address on your account, not the device.
Request a reset link to your registered email
Retry with email, not a username
Android or iOS below the floor
Android 8.0+ and iOS 15+ are the floors, so a phone below either will find no compatible build or refuse to finish installing 47 MB.
Check the software version in Settings
Use the browser version instead
A block you can lift and relock
An install halted by the handset itself is the phone shielding you from an unknown source, not the file failing, and the warning names that source.
Allow that one source in settings
Turn the permission off afterwards
A current app, and a tidy exit
Reopen Google Play or App Store listing
Let the new build land, then open it
Confirm the details show version 4.8.2
Long-press the icon, then uninstall
Delete the saved APK from your downloads
Clear any Home Screen shortcut it added

Notifications, storage and tablet use
Skim six replies to see what this Malta-licensed operator does by default, and why.
trustWhat happens when I switch app notifications off?+
Switching them off stops the pushes but leaves nothing broken. Your bets, deposits and messages still work; you simply check the app yourself. You can turn the alerts back on later in the phone's settings, and nothing about your account changes.
trustWhat if my phone only has a little space left?+
The Android build takes 47 MB and the iOS build takes 47 MB. Both sit at version 4.8.2, updated 09.2026, so leave a little space free for the next update.
trustDo I need a separate app account?+
One login covers both. Sign in with the email you registered and the app opens the same balance, the same history and the same saved payments as the browser. Keep to a single account, since duplicates are closed.
trustWhere do I claim the welcome offer?+
Yes. The welcome offer is tied to your account, not to a screen, so claiming it in the app is the same as claiming it in the browser. Wagering progress carries across both, and the terms page states the rest.
trustWhat if my phone blocks the APK download?+
A file taken from the casino site carries the same 256-bit SSL protection as the browser session. Anything arriving through a link that someone sent you should be deleted instead.
trustWhere do I get the app for my tablet?+
On an iPad, install the iOS build from the App Store; it runs on iOS 15 and above. Android tablets take the same APK as a phone. Either way the games list is the same 4,879 titles.
