Installation Steps
Start by creating an account on sb777. All it takes is an email address or mobile number — you'll be set up in under 2 minutes.
Go to your phone's Settings → Security → Unknown Sources and enable that option. This is required to install APK files.
Download the latest APK file from the sb777 website. The download takes just a few seconds.
Tap the downloaded file to install it, then log in and enjoy everything the app has to offer.
IOS users can visit the sb777 website through Safari and tap "Add to Home Screen" for a full app-like experience — no App Store required.
Built with PWA (Progressive Web App) technology, this version runs great on iOS 13 and above. You get push notifications, offline browsing, and a home screen shortcut — all included.

Steps to Install on iOS
Use Safari on your iPhone or iPad. PWA installation does not work properly on Chrome or Firefox.
Type sb777.ng in Safari and once the website loads, tap the Share button at the bottom.
From the share menu, select "Add to Home Screen", confirm the name, and tap "Add".
From now on, tapping the sb777 icon on your home screen will open it just like a native app.
Running low on storage? No problem. The sb777 web version works perfectly on all major browsers — Chrome, Firefox, Samsung Internet, and more. Just log in and play directly, no download or installation needed.
The browser version has everything — live betting, slot games, Live Casino, fast deposits and withdrawals — no features left out. Our responsive design works equally well from 320px screens all the way up to 4K displays.
The sb777 web version can be run in lite mode, working smoothly even on a 3G connection — including in remote areas of Bangladesh.
SSL/TLS encryption is fully active on the browser version too. Your login credentials and transactions are completely secure.
Life in Bangladesh moves fast. On a rickshaw, during an office break, or on the way home — your phone is your closest companion. The sb777 app was designed with this lifestyle at its core.
The app interface is fully localized — menus, buttons, and notifications are all easy to navigate, so anyone can use sb777 without any difficulty.
Push notifications are another major benefit. You'll get alerts on your phone before your favorite team's match kicks off, when odds shift significantly, or when your bet wins — so you never miss an important moment.
Everything in the sb777 App — All in One Place
The sb777 app loads in under 0.8 seconds. Even on a slow network, page loading is never an issue.
Log in in seconds using your fingerprint or Face ID. No more remembering passwords.
Customize notifications separately for match starts, odds changes, win alerts, and special offers.
Deposit and withdraw securely via mobile banking or bank transfer — all from within the app.
Watch selected matches live right in the app and place live bets at the same time — no need for two screens.
A full dark theme for comfortable late-night sessions. It also noticeably reduces battery drain.
Some people assume a mobile app can't match the desktop experience. With sb777, that's simply not the case. Our mobile app gives you the full Sports Betting section, all slot games, Live Dealer Casino, Virtual Sports, and eSports betting.
Deposit and withdrawal options are just like desktop — mobile banking, bank cards, and e-wallets are all supported in the app. VIP program, bonus claims, and tournament participation can all be handled from your mobile.
The live chat support feature works fully within the app as well. Even at 3 AM, you can reach support directly from the app whenever you need help.
Start Downloading NowSmartphone users in Bangladesh now number in the tens of millions. A huge share of internet users do everything on mobile — banking, shopping, entertainment. sb777 was built with exactly this reality in mind, making it Bangladesh's best betting mobile app.
Android phones far outnumber iOS devices in Bangladesh. Whether you're on a budget Symphony or Walton handset or a high-end device, the sb777 APK runs smoothly on all types of Android phones.
You'll need to enable "Unknown Sources" before installing the APK — this is safe because our APK is digitally signed and regularly scanned for malware. You can turn this setting back off once the installation is complete.
Many people assume PWA means a weaker experience — but sb777's iOS PWA is built with the latest technology. Thanks to Service Worker caching, the app opens much faster after the first load. Adding it to your home screen launches it in full-screen mode with no browser toolbar in sight.
Sb777 PWA works seamlessly on iPhone 12, 13, 14, and 15. Even older models like the iPhone SE and iPhone 8 run it without any issues.
When you log in to sb777, your session is secured with an encrypted token. Even if someone gets hold of your phone, they cannot open the app without your biometric lock or PIN. You'll also get an instant notification any time a new device logs into your account.
Keeping two-factor authentication (2FA) enabled adds a strong layer of security to your account. Without the OTP code, no one can log in — not even if they have your password.
The payment section in the sb777 app is designed specifically with mobile users in mind — large buttons, clear instructions, and an easy deposit flow anyone can follow.
When depositing via mobile banking, the sb777 app automatically detects your payment app and routes the payment to the correct number. The risk of a wrong transaction is virtually zero.
Sb777 releases at least one update every month, bringing new features, performance improvements, and security patches. Android APK users with auto-update enabled will be updated automatically. The iOS PWA always loads the latest version each time you open it.
If you run into any issues during installation, our 24/7 live chat support is ready to help. Chat in Bengali and get your problem resolved.
