Install the App in 3 Steps
Android installation uses an APK file because the app is distributed directly rather than through the Play Store — this is standard for casino apps in Indonesia. The file is around 30MB, so it downloads in under a minute on most connections. iOS access goes through the App Store in eligible regions. Once installed, sign in with the same username and password
you use on the desktop site — no separate account needed. Your wallet, history, and saved settings all sync automatically the first time you open the app.
- Download the APK or App Store link — Visit the gas4d mobile page on your phone's browser and tap the Android or iOS download button. The APK file will save to your downloads folder.
- Allow install from unknown sources (Android only) — Go to Settings, then Security or Privacy, and enable 'Install unknown apps' for your browser. This is a one-time step required for side-loaded APK files.
- Open and sign in — Tap the installed app icon, enter your gas4d username and password, then enable biometric login when prompted so future sessions open with just a fingerprint tap.
