The 399 app brings the full platform to your Android or iOS device. Fishing games, live casino, bingo, slots, and sports betting — all running smoothly on your phone, wherever you are in Bangladesh. Download the 399 app once and you will never need to open a browser again.
The 399 app is not just a mobile version of the website. It is a purpose-built app designed for players in Bangladesh who want a faster, smoother, and more convenient gaming experience on their phone.
The 399 app loads games significantly faster than a mobile browser. Because the app is installed directly on your device, it does not need to reload pages or re-fetch assets every time you open it. Games like Fishing Yi Lu Fa and Boat of Fortune feel noticeably more responsive on the app compared to playing through a browser.
Never miss a promotion again. The 399 app sends push notifications directly to your phone when a new bonus is available, when a withdrawal is processed, or when a special event is running. You do not need to check the website — the app keeps you informed automatically so you can grab offers before they expire.
Every element of the 399 app — game controls, deposit buttons, navigation menus, and account settings — has been designed specifically for touchscreen use. Buttons are the right size, text is readable without zooming, and the layout adapts perfectly to any screen size from a small budget Android to the latest iPhone.
Deposit and withdraw using bKash, Nagad, or Rocket without ever leaving the 399 app. The payment flow is integrated directly into the app so you do not need to copy account numbers or switch between apps. Tap deposit, enter the amount, confirm on your mobile banking app, and your 399 balance updates within minutes.
The 399 app supports fingerprint and face unlock on compatible devices. Once you have logged in once, you can use your phone's biometric security to sign in instantly on every future visit. No typing your password every time — just a tap or a glance and you are inside your account.
The 399 app updates itself in the background so you always have the latest version with the newest games, security patches, and features. You do not need to manually check for updates or re-download the app. Everything stays current automatically, keeping your experience smooth and your account protected.
Getting the 399 app on your phone takes less than five minutes. Follow these steps for Android or iOS and you will be playing within minutes of downloading.
Go to your Android Settings, then Security or Privacy, and enable "Install from Unknown Sources" or "Allow this source". This is required because the 399 APK is downloaded directly rather than from the Play Store.
Tap the "Download for Android APK" button on this page. The 399 APK file will download to your phone's storage. The file is small — under 30 MB — so it downloads quickly even on a standard mobile connection.
Open your Downloads folder, tap the 399 APK file, and tap "Install" when prompted. The installation takes about 30 seconds. Once complete, the 399 app icon will appear on your home screen.
Open the 399 app, tap "Login" if you already have an account, or tap "Register" to create a new one. Your existing account works on the app — no need to create a separate account for mobile.
The 399 iOS app installs as a Progressive Web App (PWA). Open Safari — not Chrome or another browser — and navigate to 399.today. Safari is required for the PWA installation feature to work on iPhone and iPad.
At the bottom of Safari, tap the Share icon — it looks like a box with an arrow pointing upward. A menu will appear with several options for sharing and saving the page.
Scroll down in the Share menu and tap "Add to Home Screen". Give it a name — "399" works fine — and tap "Add". The 399 app icon will appear on your iPhone home screen just like a regular app.
Tap the 399 icon on your home screen. It opens in full-screen mode without the Safari browser bar, giving you a clean app-like experience. Login with your existing account or register a new one to get started.

Most players in Bangladesh access 399 from their mobile phones, and the 399 app is built specifically for that reality. Mobile internet in Bangladesh — whether Grameenphone, Robi, Banglalink, or Teletalk — can vary in speed and stability. The 399 app is optimised to handle these conditions better than a standard mobile browser.
The app uses less data than the website because it caches game assets locally after the first load. This means that if you play Fishing Yi Lu Fa regularly, the game loads faster every time you open it because the app does not need to re-download the same graphics and sounds. For players on limited data plans, this makes a real difference.
The 399 app also handles connection drops more gracefully than a browser. If your mobile signal cuts out briefly during a game session, the app will attempt to reconnect automatically rather than showing an error page. Your game state is preserved where possible, so you do not lose progress because of a momentary signal issue.
Every game available on the 399 website is also available on the 399 app. There is no reduced game library on mobile — you get the full experience. Here is what you can play after downloading the 399 app:
The 399 app makes managing your money as easy as playing games. Deposits via bKash, Nagad, and Rocket are fully supported and the process is straightforward. Open the app, go to the Deposit section, choose your payment method, enter the amount, and follow the on-screen instructions. Your balance is updated within a few minutes of a successful deposit.
Withdrawals work the same way. Go to the Withdraw section in the app, enter the amount you want to withdraw and your bKash or Nagad number, and submit the request. Withdrawal processing times on 399 are among the fastest available for players in Bangladesh, with most requests completed within the same day.
All financial transactions on the 399 app are protected by the same SSL encryption used on the website. Your payment details are never stored on your device — they are processed securely through the 399 payment system.
This usually means "Install from Unknown Sources" is not enabled. Go to Settings, search for "Unknown Sources" or "Install Unknown Apps", and enable it for your browser or file manager. Then try installing the APK again.
Try closing other apps running in the background to free up RAM. If the issue persists, clear the 399 app cache from your phone's App Settings. Also check that you are on a stable 4G or Wi-Fi connection — a weak signal will cause games to lag regardless of the device.
Make sure you are using Safari, not Chrome or Firefox. The "Add to Home Screen" option only appears in Safari's Share menu. If you are already in Safari and cannot see it, scroll down in the Share menu — it may not be visible without scrolling.
Pull down on the main screen to refresh, or go to Account and tap the refresh icon next to your balance. If the balance still does not update, log out and log back in. If you continue to have issues, visit the FAQ page or contact 399 support via live chat.
New to 399? You do not need an account before downloading the app. Download first, then register directly inside the app. The registration process takes about three minutes and you can make your first deposit immediately after.
