The 399 Bet Android app puts 500+ games, instant bKash deposits, live casino tables, and real-time bonuses right in your pocket. Fast to install, smooth to use, and built for Bangladesh mobile players.
Free download for Android — no Play Store needed. Enable "Unknown Sources" and install in under 60 seconds.
Four simple steps and you are playing on the 399 Bet app in under two minutes.
Go to your Android Settings, then Security or Privacy, and turn on "Install from Unknown Sources" or "Allow from this source." This lets you install APK files that are not from the Play Store. You only need to do this once.
Tap the Download Android APK button on this page. The 399 Bet APK file is only 18 MB, so it downloads in seconds even on a 3G connection. Your browser will save it to your Downloads folder automatically.
Open your Downloads folder and tap the 399 Bet APK file. Your phone will ask you to confirm the installation. Tap Install and wait about 10 seconds. The 399 Bet app icon will appear on your home screen when it is done.
Open the app, log in with your 399 Bet account details, and you are in. Your wallet balance, active bonuses, and the full game library are all right there. Not registered yet? Create a free account directly inside the app.
No iOS version yet: The 399 Bet app is currently available for Android only. iPhone and iPad users can access the full platform through the mobile browser at 399-bet.top — the browser version works just as well and includes all the same games, bonuses, and payment options.
The 399 Bet app is built from the ground up for mobile players in Bangladesh. Here is what makes it different.
The 399 Bet app loads games up to 40% faster than the mobile browser version. Game assets are cached locally on your device, so even on a slow 3G connection you get smooth gameplay without constant buffering or lag. This matters a lot when you are in the middle of a fishing game or a live casino round.
Never miss a bonus offer again. The 399 Bet app sends you push notifications for new promotions, deposit match offers, reload bonuses, and tournament alerts. You can customise which notifications you receive from the app settings so you only get the ones that matter to you.
The 399 Bet app integrates directly with bKash and Nagad so you can deposit with a single tap. Your payment details are saved securely, and deposits are credited to your game wallet instantly. Minimum deposit is just ৳200, making it easy to top up whenever you want.
Log in to the 399 Bet app using your fingerprint or face unlock — no need to type your password every time. Biometric login is faster, more secure, and works on any Android device that supports fingerprint or face recognition. Your account stays protected even if your phone is lost or stolen.
Every single game available on the 399 Bet website is also available in the app — fishing games, All-Star Fishing, Teen Patti Joker, live casino tables, slots, and sports betting. The app game lobby is organised by category so you can find your favourite game in seconds without scrolling through hundreds of titles.
The 399 Bet app checks for updates automatically every time you open it. When a new version is available, it downloads and installs in the background without interrupting your session. You always have the latest features, security patches, and game additions without having to manually re-download the APK.
The 399 Bet app is the most convenient way to access everything the platform has to offer. Whether you are commuting in Dhaka, relaxing at home in Chittagong, or taking a break anywhere in Bangladesh, the app gives you instant access to your account, your wallet, and 500+ games — all from a single icon on your home screen.
We built the 399 Bet app specifically for the way people in Bangladesh use their phones. Most of our players are on Android devices, often with limited storage and variable mobile data speeds. That is why the app is only 18 MB — small enough to download quickly even on a 3G connection, and light enough to run smoothly on budget Android phones without draining your battery or eating up your storage.
The app is not just a wrapper around the website. It is a fully native Android application with features you cannot get in the browser — push notifications for bonus alerts, biometric login with your fingerprint, faster game loading through local caching, and a streamlined one-tap deposit flow for bKash and Nagad. These features make a real difference to your daily experience on the platform.
Security is built into every part of the 399 Bet app. All data between the app and our servers is encrypted with SSL. Biometric login means your account is protected even if someone else picks up your phone. And our fraud detection system monitors every login and transaction in real time, so any suspicious activity is flagged and blocked before it can affect your account or your funds.
Every game on the platform is available in the app. Here is a quick overview of what you can play:
Both the 399 Bet app and the mobile browser version give you access to the same games, bonuses, and payment options. The difference is in the experience. The app is faster, supports biometric login, sends push notifications, and has a more polished interface designed specifically for touchscreen use. If you play regularly, the app is the better choice. If you just want to try the platform before committing, the browser version at 399-bet.top works perfectly well on any mobile browser.
