The 77z app is available on both Android and iOS. Live scores, quick betting, instant deposits and withdrawals — everything in one place.
77z App – The Full Betting Experience on Your Smartphone
See at a glance how the 77z app differs from a standard mobile site.
As a native app, 77z loads up to three times faster than a mobile browser — smooth performance even on a slow connection.
Odds update every second during a live match. Live scores and ball-by-ball analysis — all in one place on the app.
Get instant notifications on your phone before a match starts, when a goal is scored, or when odds shift significantly. Never miss a moment.
Log in to your account in just one second using fingerprint or Face ID. No password typing needed.
Deposit directly from Mobile Banking, Nagad, or Rocket. Withdraw your winnings in just a few minutes.
Slots, Live Casino, poker, roulette — every game is playable right in the app. A full desktop-quality experience on mobile.
Android users can install the app by downloading the APK file directly. Even though it is not on the Google Play Store, it is completely safe and virus-free. You will need to change one small setting before installing — just follow the steps below.
Before downloading the APK file, go to your phone's Settings → Security → Unknown Sources Enable the option.
Open 77z.vin in your browser and go to the "App" section from the top menu.
The download will start automatically. File size is typically between 30–45 MB.
Open the downloaded file from your notification bar or file manager.
Once installation is complete, the 77z icon will appear on your home screen.
If you already have an account, just log in. If not, you can create a new one in under a minute.
77z Android App – Quick Install, Smooth Performance
77z iOS App – A Seamless Experience on iPhone and iPad
Installing the 77z app on iOS works a little differently. Even though it is not available directly on the App Store, you can get the full app experience via the web app (PWA) or sideloading. The whole process only takes a few minutes.
On iOS, you will get the full app experience only by adding the site to your home screen through Safari.
Look for the share button — the box with an arrow icon — in the bottom bar of Safari.
Select "Add to Home Screen" from the menu.
Enter 77z as the name and tap Add — the app icon will appear on your home screen right away.
From now on, you can open 77z directly from the home screen icon — just like a native app.
Installing via PWA on iOS enables push notifications, fullscreen mode, and some offline features. A fully native iOS app is coming soon.

With mobile internet usage in Bangladesh growing rapidly over the past few years, betting through a mobile app has become the go-to choice for many users. The 77z app was built with exactly that in mind — designed around the network limitations, device specs, and payment methods of Bangladeshi users.
Many betting platforms require a high-end phone to run their app. The 77z app, however, runs on Android 6.0 and above — meaning it works just fine on budget phones from 2017 and 2018. That is a significant advantage, especially given that most active users in Bangladesh are on mid-range or budget smartphones.
Another standout feature of the 77z app is full Bengali language support. Menus, instructions, and support chat are all available in Bengali. For users who are not comfortable in English, this makes for a genuinely easy experience.
Payments in the 77z app are built around Bangladesh. Mobile Banking, Nagad, and Rocket — all three mobile banking services are available directly within the app. No need to open a separate browser or leave the app. Deposits are completed in just a few taps.
Cricket in this country is more than a sport — it is a passion. The 77z app offers live betting on all Bangladesh cricket matches. IPL, BPL, World Cup — special markets are open in the app for every major tournament. Ball-by-ball updates, wicket alerts, and live match scores, all in one place.
Beyond sports, the 77z app includes a full casino section. Live baccarat, roulette, blackjack, and hundreds of slot games — all running smoothly on the app. Casino game graphics are optimized for mobile screens, so they look great too.
Support matters too. The 77z app has a built-in live chat feature. If you run into any issue, you can talk to the support team in Bengali without ever leaving the app — any time of day or night. For many users, that kind of accessibility is a real relief.
Exclusive App Bonus: A special welcome bonus is available on your first deposit through the 77z app. This bonus is not offered on the website — it is exclusive to app users.
