Both versions of the bet399 app are built for Bangladesh players — fast, lightweight, and fully integrated with local payment methods. Pick your platform and get started in minutes.
The bet399 Android app is distributed as a direct APK download — no Play Store required. It installs in under 60 seconds and runs on any Android device version 6.0 or above. The APK is scanned and verified before every release.
You may need to enable "Install from unknown sources" in your Android settings before installing. Full instructions are on the page below.
The bet399 iOS app is available through the App Store and installs like any other iPhone or iPad app. No special settings required — just search for bet399, tap install, and you're ready to play within seconds of the download completing.
iOS installation is straightforward — no additional steps needed. Your Apple ID must be set to a supported region to find the app in the App Store.
Because the bet399 Android app is distributed as a direct APK rather than through the Play Store, there's one extra step compared to a standard app install. It takes about 30 seconds and you only need to do it once. Here's the full process from start to finish.
Go to Settings on your Android device. The exact menu name varies by manufacturer — on Samsung it's usually under "Biometrics and Security", on other devices it may be under "Privacy" or "Apps".
Find the option labelled "Install unknown apps" or "Unknown sources" and enable it for your browser app (Chrome, Firefox, or whichever browser you use to download the APK). This tells Android it's okay to install apps from sources other than the Play Store.
Tap the Download Android APK button on this page. The file will download to your phone's Downloads folder. The file size is 28 MB — on a standard 4G connection it takes under 30 seconds.
Once the download completes, tap the notification or open your Downloads folder and tap the bet399 APK file. Android will ask you to confirm the installation — tap Install.
The app installs in seconds. Tap Open, log in with your bet399 account details, and you're ready to play. If you don't have an account yet, tap Register and complete the quick sign-up process directly in the app.
Installing bet399 on iPhone or iPad is simpler than the Android process — it works exactly like any other App Store download. No settings changes required.
Tap the Download iOS App button on this page. You'll be taken to the bet399 listing in the App Store. Make sure you're signed into your Apple ID before proceeding.
On the bet399 App Store listing, tap the Get button. You may be asked to confirm with Face ID, Touch ID, or your Apple ID password — this is standard App Store security, not specific to bet399.
The app is 31 MB and downloads quickly on any Wi-Fi or mobile data connection. You'll see the progress circle on the app icon on your home screen.
Tap the bet399 icon on your home screen. Log in with your existing account or register a new one directly in the app. The full game library and all payment options are available immediately after login.
The bet399 app isn't a stripped-down mobile version — it's the full platform. Everything available on the desktop site is available in the app, optimised for touchscreen use.
Every game on bet399 is available in the app — slots, crash games, live casino, sports betting, and more. The game library in the app is identical to the desktop version, with no titles removed or restricted for mobile.
Deposit and withdraw directly through bKash, Nagad, or Rocket from within the bet399 app. The payment flow is integrated natively — you don't need to switch between apps or copy account numbers manually.
Get notified about new promotions, deposit bonuses, and game launches the moment they go live. bet399 push notifications are opt-in — you control what you receive and can turn them off at any time from your phone's settings.
The bet399 app is optimised for Bangladesh's mobile network conditions. Games load quickly even on 4G connections, and the app uses less data than the browser version — important for players on limited data plans.
Log in to bet399 with your fingerprint or face recognition instead of typing your password every time. Biometric login is faster, more secure, and works on any Android or iOS device that supports it.
The bet399 live chat support is built into the app. If you have a question about a deposit, a game result, or your account, you can reach the support team without leaving the app — available 24 hours a day.
Most Bangladesh players access bet399 on a mid-range Android phone with a 4G connection. The app is designed around that reality — small file size, low data usage, large touch targets, and a payment flow that works with the mobile wallets already on your phone. It's not a desktop site squeezed onto a small screen; it's a purpose-built mobile experience.
You can play bet399 in a mobile browser without downloading anything. But the app offers a noticeably better experience in several areas that matter for daily play.
