18+ Only — The 399 bd app is intended for adults aged 18 and above. By downloading and using the app, you confirm that you meet the minimum age requirement. Gambling involves financial risk — please play responsibly.

Android Installation Steps

Installing the 399 bd APK on Android takes under three minutes. Follow these steps carefully — especially the "Unknown Sources" setting which is required for all third-party APK installs in Bangladesh.

1

Open the 399 bd Website in Your Browser

On your Android device, open Chrome, Firefox, or any browser and navigate to 399-bd.app. Tap the Download button on this page. Your device will begin downloading the APK file (approximately 28 MB). You may see a warning that the file is an APK — this is normal for apps downloaded outside of the Google Play Store.

2

Allow Installation from Unknown Sources

Go to your device Settings → Security (or Privacy, depending on your Android version). Enable the "Install Unknown Apps" or "Unknown Sources" toggle. On newer Android versions (8.0+), you will be prompted to grant this permission specifically to your browser — tap "Allow from this source". This is a one-time setting that many Bangladesh players on Walton, Symphony, and Xiaomi devices have already configured.

3

Open the Downloaded APK File

Pull down your notification shade and tap the downloaded APK file, or open your device's file manager and locate the file in the Downloads folder. Tap the file to begin the installation wizard. Android will display a list of permissions the app requires — these are standard for a casino and betting application (internet access, storage, notifications).

4

Tap Install and Wait

Tap the "Install" button on the Android installation screen. The process typically takes 15–30 seconds. Once complete, tap "Open" to launch 399 bd immediately, or find the 399 bd icon on your home screen or app drawer.

5

Log In or Register Your Account

Open the app, tap "Login" if you already have a 399 bd account, or follow the registration flow to create a new account. Deposit via bKash, Nagad, or Rocket and you are ready to play. The whole process from fresh install to first bet takes under five minutes.

iOS Installation Steps

iPhone and iPad users install 399 bd as a Progressive Web App through Safari. No App Store approval needed, no storage charges — just a clean, fast app icon on your home screen.

1

Open Safari on Your iPhone or iPad

The PWA install method works exclusively through Apple's Safari browser. If you are currently reading this in Chrome or Firefox on iOS, copy the URL and paste it into Safari. The PWA install option is not available in third-party iOS browsers due to Apple platform restrictions.

2

Tap the Share Icon

In Safari's bottom toolbar, tap the Share icon — it looks like a square with an upward-pointing arrow. Scroll through the share sheet options that appear. You may need to scroll down past AirDrop and messaging options to find the home screen option.

3

Tap "Add to Home Screen"

Tap "Add to Home Screen" from the share sheet. A dialog will appear showing a preview of the 399 bd icon and the default name. You can rename it if you wish, though "399 bd" is pre-filled. Tap "Add" in the top-right corner to confirm.

4

Find the 399 bd Icon on Your Home Screen

The 399 bd icon will appear on your iOS home screen just like any native app. Tap it to open the platform in a full-screen, browser-chrome-free experience. iOS 16.4 and above also supports push notifications for the PWA — enable them when prompted so you never miss a live BPL match alert.

5

Log In and Start Playing

Tap your new 399 bd home screen icon, log in with your account credentials, and you are ready. Deposits via bKash and Nagad work identically on iOS and Android — the payment flow is fully mobile-optimised regardless of your device.

App Features and Game Categories

The 399 bd mobile app is not a stripped-down version of the desktop site — it is the full platform, rebuilt from the ground up for touch screens and mobile data connections common across Dhaka, Sylhet, and Chittagong.

Cricket Betting

Live in-play betting on BPL, IPL, T20 World Cup, and all major Bangladesh Tigers fixtures. Match winner, top batsman, total sixes, and powerplay markets — all accessible in two taps.

Slot Games

Hundreds of video slots from Pragmatic Play, NetEnt, and Microgaming. Swipe-optimised game lobby with filters by provider, volatility, and RTP. Megaways and jackpot titles included.

Live Casino

HD live streams from Evolution Gaming and Ezugi studios. Play Baccarat, Roulette, Blackjack, and Crazy Time with real dealers on your phone — even on a standard 4G connection.

Crash Games

Aviator by Spribe and other crash titles with touch-optimised cash-out buttons. The large tap targets make mobile play fast and accurate — no missed cash-outs due to small buttons.

Teen Patti

Classic, Joker, and AK47 variants available in both RNG and live-dealer formats. The card animation and chip UI are redesigned for portrait-mode mobile play — fluid and intuitive.

Andar Bahar

30-second rounds make Andar Bahar perfect for mobile sessions during a commute. The near 50/50 odds and minimal UI clutter make this one of the most-played games on the 399 bd app.

Instant Deposits

Tap-to-pay bKash and Nagad integration built directly into the app. No redirection to external pages — deposits confirm in seconds so you can get back to your game without interruption.

Push Notifications

Opt-in alerts for upcoming BPL match start times, bonus credit confirmations, withdrawal status updates, and exclusive mobile-only promotions available only to app users.

Frequently Asked Questions About the Download

Common questions from Bangladesh players about installing and using the 399 bd mobile app. If your question is not answered here, our 24/7 live chat support team is always available.

Yes, the 399 bd Android APK and iOS PWA are completely free to download and install. There are no download fees, subscription charges, or in-app purchase requirements to access the platform. You only spend money if you choose to deposit funds and place real-money bets.

The 399 bd APK is safe when downloaded directly from 399-bd.app. Our APK file is code-signed and scanned regularly for malware. We strongly recommend downloading only from this official source — not from third-party APK sites or mirror downloads, which may be tampered with. Thousands of Bangladesh players install the app each month without any issues.

Android shows a warning for any app installed outside of the Google Play Store — this is a standard system security message, not a sign that the file is harmful. Since 399 bd is an online gaming platform not listed on Google Play, the APK is distributed directly. Simply enable "Install from Unknown Sources" for your browser as described in the installation steps above, and the warning will not block the install.

Yes. Your 399 bd account is linked to your registered phone number and works across all devices — Android app, iOS PWA, and desktop browser. Your wallet balance, bonus credits, bet history, and account settings are fully synchronised in real time. You can start a session on desktop and continue on your phone without any interruption.

When a new version of the 399 bd app is available, you will receive a push notification prompting you to update. Tap the notification to download and install the latest APK — the process takes under 60 seconds. Alternatively, open the app and look for the update banner on the home screen. iOS PWA users receive updates automatically whenever they open the app, as the PWA always fetches the latest version from the server.

Most features of 399 bd — including sports betting, slots, and Teen Patti — work well on a standard 3G connection. Live casino streaming requires at least 4G for a smooth HD experience. If you are in an area with limited connectivity, such as rural Sylhet or Rangpur, we recommend sticking to slot games and sports betting which use significantly less data than live dealer streams.

Our 24/7 live chat support team can walk you through any installation issue step by step. Access live chat by logging into your account at 399-bd.app on your browser. You can also email us at [email protected] — plain text address, not a link — and our team typically responds within 4 hours during Bangladesh Standard Time (BST, UTC+6) business hours.

Yes. The 399 bd app is strictly for adults aged 18 and above. By downloading, installing, and using the app you confirm that you are at least 18 years old. We conduct age verification checks during the account registration and KYC process. If you are concerned about underage access, please use the parental controls available on your Android or iOS device to restrict access to the app.
