Install the App in 3 Steps
Android users download the APK directly from the bank303 login site — no app store needed. Before you tap the file, go to your phone Settings, open Security or Privacy, and switch on 'Install from unknown sources' for your browser. The file is around 30MB so it downloads fast on mobile data. iOS users find the app through the link on our
site, which opens the correct App Store page for supported regions. After install, open the app, enter your account details, and confirm with the OTP sent to your registered number. Your account wallet and game history carry over automatically — nothing to set up again.
- Download the APK or App — Tap the download link on the bank303 login site. Android gets the APK file; iOS opens the App Store page directly.
- Allow Install from Unknown Sources — Android only — open Settings, go to Security or Privacy, and enable installs from your browser before opening the APK file.
- Open and Sign In — Launch the app, enter your account credentials, and confirm the OTP. Your wallet balance and game history load immediately.
