Installing the 399 BDT app on Android takes less than two minutes. Because the app is distributed as a direct APK file rather than through the Play Store, you'll need to allow installation from unknown sources — this is a standard one-time step for any APK download in Bangladesh and is completely safe.
The 399 BDT APK is scanned and verified before every release. It contains no malware, no adware, and no hidden permissions beyond what the app needs to function.
Open 399-bdt.org in your Android browser and navigate to the App page. Tap the "Download Android APK" button to start the download.
When prompted, go to Settings > Security > Install Unknown Apps and allow your browser to install APK files. This is a one-time setting you only need to change once.
Once the download finishes, tap the notification or find the file in your Downloads folder. Tap it to begin installation and follow the on-screen prompts.
Open the 399 BDT app, tap Login if you already have an account, or tap Register to create a new one in under two minutes. Your welcome bonus is waiting.
Visit 399-bdt.org using Safari on your iPhone or iPad. Other browsers on iOS may not support the installation process correctly, so Safari is recommended.
Tap the iOS download button on this page. You'll be guided through a short profile installation process — this is how iOS apps outside the App Store are distributed.
Go to Settings > General > VPN & Device Management, find the 399 BDT profile, and tap "Trust". This allows the app to run on your device.
Find the 399 BDT app icon on your home screen, tap to open, and login or register. The full platform — live casino, crash games, sports — is ready to go.
iPhone users can install the 399 BDT app through a simple profile installation via Safari. The process takes about two minutes and doesn't require jailbreaking your device. Once installed, the app works exactly like any other app on your home screen.
The 399 BDT iOS app installs via a standard enterprise distribution profile. Your device does not need to be jailbroken and your warranty remains intact.
Both work, but the 399 BDT app gives you a noticeably better experience across the board.

The 399 BDT app was built with one thing in mind — making it as easy as possible for players in Bangladesh to access their favourite games from anywhere, at any time. Most players in Bangladesh use their phones as their primary device for everything, and the 399 BDT app is designed around that reality. It's lightweight, it's fast, and it works well even when your mobile data signal isn't perfect.
When you download the 399 BDT app, you're not getting a stripped-down version of the platform. You get the full thing — every game, every payment method, every promotion, and the same account you'd access on a desktop browser. The app just makes it more convenient. One tap to open, biometric login if your phone supports it, and you're straight into your account dashboard.
Every game on the 399 BDT platform is available through the app. That includes Happy Fishing, Fortune Snake, Boxing, EVO Live casino tables, Cockfighting, and Go Rush. The full Games lobby is accessible from the app's home screen, with all categories clearly laid out so you can find what you want without scrolling through pages of content.
One of the biggest advantages of the 399 BDT app over the browser version is how payments work. When you tap to deposit via bKash or Nagad inside the app, it deep-links directly to your bKash or Nagad app — no copying account numbers, no switching between browser tabs. You confirm the payment in your mobile banking app and the funds appear in your 399 BDT balance within seconds. Withdrawals work the same way. It's the smoothest payment experience available for online gaming in Bangladesh.
Yes. The 399 BDT app is safe to download and install. The APK file is scanned for malware before every release and only requests the permissions it actually needs — camera access for biometric login, notification permission for bonus alerts, and network access to connect to the platform. It does not access your contacts, messages, or any other personal data on your device.
Because the 399 BDT app is distributed as a direct APK rather than through the Google Play Store, Android will ask you to allow installation from unknown sources. This is a standard Android security prompt that appears for any APK downloaded outside the Play Store — it doesn't mean the file is unsafe. Millions of apps in Bangladesh are distributed this way, including many banking and utility apps.
The 399 BDT app runs on Android 6.0 and above, which covers the vast majority of Android phones currently in use in Bangladesh. For iOS, the app requires iOS 12 or later. The app is only 18MB in size, so it won't take up much space on your device and the download is quick even on a slower connection. A minimum of 1GB RAM is recommended for the smoothest experience, though the app will run on devices with less.
If you're new to 399 BDT, you can register directly inside the app or through the Register page. Creating an account takes under two minutes — just your mobile number and a password. Once you're registered, you can make your first deposit via bKash or Nagad and claim your welcome bonus immediately. Everything is handled inside the app from start to finish.
399 BDT is committed to responsible gaming. The app includes built-in tools to set deposit limits, session time reminders, and self-exclusion options. Visit our Responsible Gaming page to learn more. 18+ only.
