The 4777 BTU app isn't just a smaller version of the website — it's built from the ground up for mobile betting. Here's what makes it different.
The 4777 BTU app is optimised for Bangladesh mobile networks. Whether you're on 4G, 3G, or a slower connection, the app loads quickly and stays responsive. Games launch fast, odds update in real time, and your BDT balance refreshes instantly after every transaction.
Enable push notifications on the 4777 BTU app and never miss a promotion, bonus credit, or game result. Get alerts when your withdrawal is processed, when a new bonus is available, or when a game you follow has live odds open. You control which notifications you receive.
Log in to the 4777 BTU app using your fingerprint or face ID — no need to type your password every time. Biometric login is fast, secure, and works on most modern Android and iOS devices. Your credentials are stored locally on your device and never transmitted.
Deposit and withdraw in BDT directly from the 4777 BTU app. The mobile cashier supports all the same payment methods as the desktop site. Check your balance, request a withdrawal, and track transaction history — all from your phone without switching to a browser.
Your loyalty points balance is visible right on the 4777 BTU app home screen. Every bet you place through the app earns points toward your next reward tier. Redeem points, check your tier progress, and claim loyalty bonuses — all without opening a desktop browser.
The 4777 BTU app uses the Slate Bronze theme throughout — dark backgrounds, bronze gold accents, and high-contrast text that's easy to read in any lighting. Whether you're betting in bright sunlight or late at night, the app is comfortable on your eyes.
Getting the 4777 BTU app set up takes less than two minutes. Follow these steps and you'll be placing bets in BDT from your phone before you know it.
Android users: You may need to enable "Install from unknown sources" in your device settings before installing the 4777 BTU APK. This is a standard Android security step for apps installed outside the Play Store — it's safe and takes five seconds to enable.
If you don't have a 4777 BTU account yet, register for free at 4777-btu.app/register. It takes under two minutes. If you already have an account, just log in at 4777-btu.app/login — your existing credentials work on the app.
Open your mobile browser and navigate to 4777-btu.app/app. The page will detect your device type and show you the correct download option — APK for Android or PWA installation for iOS. No need to search an app store.
Tap the download button and wait for the file to save to your device. On Android, open the APK file from your downloads folder and tap Install. On iOS, tap "Add to Home Screen" from your browser's share menu to install the 4777 BTU app as a PWA.
Open the 4777 BTU app from your home screen, log in with your username and password, and you're in. Your BDT balance, bet history, bonuses, and game access are all exactly as you left them on the desktop site.

Most people in Bangladesh do everything on their phone — banking, shopping, entertainment. Betting should be no different. The 4777 BTU app was built with that in mind. It's not a desktop site squeezed onto a small screen. It's a proper mobile betting app, designed from scratch for the way Bangladesh players actually use their phones.
Every game available on the 4777 BTU desktop site is available on the app. That means Nine, Slots, Ice Hockey, Dino Hunter, and Swimming are all accessible from your phone. The game interfaces are adapted for touch screens — larger tap targets, swipe-friendly navigation, and layouts that make sense on a portrait screen. You're not fighting a desktop layout on a 6-inch display.
Live odds on the 4777 BTU app update in real time, just like the desktop version. If you're watching a Swimming or Ice Hockey event and want to place a bet mid-game, the app handles it without lag. Bet slips are easy to build on mobile — tap the odds you want, enter your BDT stake, and confirm. The whole process takes seconds.
One of the most important things about the 4777 BTU app is that your account is fully synced. Your BDT balance on the app is the same as your balance on the desktop site — there's no separate mobile wallet or secondary account. Deposit on your phone, withdraw on your computer, check your bet history on your tablet. It all stays in sync automatically.
The 4777 BTU app cashier supports BDT deposits and withdrawals through the same payment methods available on desktop. If you prefer to manage your money on your phone, the app makes it easy. Deposit requests process quickly, and withdrawal requests are handled with the same speed as the desktop site.
The 4777 BTU app uses the same 256-bit SSL encryption as the desktop site. Every login, every transaction, and every bet is transmitted securely. Biometric login — fingerprint or face ID — adds an extra layer of protection without slowing you down. Your account credentials are never stored in plain text on your device.
If you lose your phone or it gets stolen, you can log out of all active sessions from any device by visiting your account security settings. This immediately ends any open sessions on the lost device, protecting your BDT balance and personal information. Contact 4777 BTU support if you need help securing your account after a lost device.
Pro Tip: Set up biometric login on the 4777 BTU app as soon as you install it. It's faster than typing your password and adds a meaningful layer of security — especially if you share your phone with family members.
The 4777 BTU app is updated regularly to add new features, improve performance, and fix any issues. On Android, you'll receive a notification when a new version of the APK is available — just download and install it over the existing version. On iOS, the PWA updates automatically when you open it with an internet connection.
Always make sure you're running the latest version of the 4777 BTU app. Older versions may not support new games or payment methods, and security patches are included in every update. If you're unsure which version you have, check the app settings screen — the version number is displayed there.
If the 4777 BTU app isn't loading or behaving unexpectedly, the first step is to close it completely and reopen it. If the issue continues, clear the app cache from your device settings — this resolves most display and loading problems without affecting your account data. For persistent issues, uninstall and reinstall the latest version of the app.
Login problems on the app are usually caused by the same things as on desktop — a wrong password or a temporarily locked account. Use the forgot password flow on the 4777 BTU website if you can't log in on the app. If you're still stuck, contact support at [email protected] and the team will help you get back in.
Register a free account, get the app on your Android or iOS device, and start betting on Nine, Slots, Ice Hockey, Dino Hunter, and Swimming — all in BDT, all from your phone.
