Install the sis4d App in 3 Steps
Android users download the APK directly from sis4d — the file is around 30MB so it transfers quickly on a mobile connection. Before you tap install, go to your phone settings and allow installation from unknown sources; this is a standard Android step for apps outside the Play Store. iOS users follow the link on sis4d to the App Store listing and
tap get. Once the app opens, sign in with your existing account or complete the short registration flow right inside the app. DANA, OVO, and GoPay are available in the cashier from the first session — no extra wallet linking required if your account is already verified. Players in Yogyakarta and across Indonesia have reported the whole process taking under five minutes
on a stable connection.
- Download the APK or App Store build — Visit sis4d on your phone browser and tap the Android or iOS download link. The Android APK is around 30MB; the iOS build installs from the App Store.
- Allow install from unknown sources (Android only) — On Android, go to Settings, then Security or Privacy, and enable 'Install unknown apps' for your browser. This is a one-time step before you tap the APK file.
- Open the app and sign in — Launch sis4d, enter your account credentials, and set up fingerprint login when prompted. Your full lobby — slots, live tables, sportsbook — is available straight away.
