ob55 App — Play Casino & Cricket Anywhere in Bangladesh

Yes — the ob55 APK file is built and hosted exclusively by ob55 at ob55.lat. It does not contain malware, spyware, or any unauthorised code. The only Android permission it requests is internet access, which is required for the game servers to work. You can verify this during install by reviewing the permissions list Android shows before you tap Install. The file is scanned before each release. Always download from ob55.lat — never from third-party links shared on Telegram or Facebook.

Android labels any APK that is not downloaded directly from the Google Play Store as an "unknown source." This is a standard Android security prompt — it does not mean the file is dangerous. Because the ob55 App is not listed on the Play Store (online betting apps are not permitted there in Bangladesh), you need to allow installation from your browser or file manager. Enable this once in Settings, install ob55, and you can disable it again straight after. This process is the same for every legitimate betting app in Bangladesh.

First, delete the downloaded ob55.apk file and re-download it fresh from this page — a corrupted download is the most common cause of install failure. If the App installs but will not open, check that your Android version is 6.0 or higher (Settings → About Phone). Make sure you have at least 120 MB of free storage and close background apps to free up RAM. If the problem continues after a clean install on a supported Android version, contact ob55 24/7 Live Chat with your phone model and Android version.

The ob55 App checks for updates automatically and shows a notification banner on the home screen when a new version is available. Tap the banner to go to the download page, download the new APK from ob55.lat, and install it over your existing App — your account, balance, and settings are all preserved. You do not need to uninstall the old version first. The current version is 2.3.15, updated 10 November 2026. If you dismissed the update notification, you can always download the latest APK from this page.

Your existing ob55 account works in the App — there is no separate App account. Open the App, tap Log In, and use the same username and password you use on the ob55.lat website. Your balance, bonus history, VIP level, and transaction records all carry over automatically. If you have forgotten your password, use the Forgot Password link on the login page to reset it before opening the App. New players should register here first.

There is no native iOS App for ob55 — Apple's App Store does not allow real-money betting apps from most operators in Bangladesh. However, iPhone and iPad users can get a very similar experience by opening ob55.lat in Safari and tapping Share → Add to Home Screen. This creates a full-screen web app icon on your home screen. All games, live casino, cricket betting, and payment methods (bKash, Nagad, etc.) work the same way. The web app updates automatically whenever ob55 pushes a site update — no manual reinstall needed.

Yes — the welcome bonus applies regardless of whether you deposit through the App or the website. First-time depositors receive a 115% bonus on their first deposit, up to ৳15,000. For example, depositing ৳5,000 gives you ৳5,750 in bonus funds, bringing your total balance to ৳10,750. The minimum qualifying deposit is ৳450. Bonus funds carry an 18x wagering requirement before withdrawal. See the full Bonus & VIP guide for terms and eligible games.
