Mobile internet usage in Bangladesh is growing rapidly, and so is the trend of mobile betting. b 77 was built with this in mind — designed specifically for Bangladeshi users and optimised for local network conditions.
Some apps consume a lot of bandwidth, making them costly to run on mobile data. The b 77 app can be used in data-saver mode, using just 30–50 MB per hour. It runs smoothly on any carrier — Grameenphone, Robi, or Banglalink.
Yes. The b 77 app runs on all devices with Android 6.0 (Marshmallow) or above, so even phones from 2016 are supported. For iOS, you'll need iOS 13 or later.
Even on 2 GB RAM, the app runs smoothly. Performance is even better on high-end devices, but b 77 works perfectly well on mid-range and budget phones too.

A common question we hear is whether to use the b 77 app or access the site through a mobile browser. Honestly, both work well — but the app comes with a few extra advantages.
The app delivers live push notifications instantly — you'll be alerted the moment odds change or your bet wins. This feature is not available on the browser.
The app also supports biometric login — something the browser doesn't offer. Sign in with your fingerprint or Face ID in just one second, which is a real advantage when you need to place a bet quickly.
No — the browser version gives you access to all features too. b 77's mobile website is fully responsive and includes every game and betting market. That said, it may use slightly more data and load a bit slower compared to the app.
If you're new to b 77, our suggestion is to try the browser version first — if you like it, go ahead and download the app. Both use the same account, so you can log in from any device.
