Why the 3111 App?
For most people in Bangladesh, a smartphone is their primary — and often only — device for getting online. The 3111 app was built with that in mind. Its file size is intentionally kept small so it runs smoothly even on budget and entry-level phones.
The app interface is entirely in Bangla — menus, notifications, transaction history, all of it. No English required. The 3111 design team has carefully tailored every section to match the reading habits and screen sizes of users in Bangladesh.

One of the biggest advantages of having the app installed is real-time notifications. Whether your favourite team is about to kick off, odds shift significantly, or your bet comes in — you'll get an instant alert on your phone. This isn't something you get from a web browser.
The 3111 app also includes a live streaming feature for selected matches. That means you're not just watching odds — you can watch the game itself, right in the same place. Catching a live stream of cricket or football while placing in-play bets takes the mobile experience to a whole new level.
Deposits and withdrawals on the 3111 app are completely hassle-free. bKash, Nagad, Rocket – Bangladesh's most popular mobile banking options are all accessible directly from the app. Deposits are typically confirmed within 30 seconds.
Withdrawals are just as straightforward. Submit a request from the Wallet section of the app and your funds will typically arrive in your mobile banking account within 24 hours. 3111 is committed to transparent, on-time payments — always.

The 3111 Android app is updated regularly. When a new version is available, you'll get a notification right inside the app — and the update downloads in a single tap. No need to come back to this page.
Skipping updates may mean some new features won't appear, so it's always best to run the latest version. From a security standpoint, updated apps are also better protected — every update includes security patches.
The official 3111 APK is malware-free and SSL-encrypted. Do not download it from third-party sites.
The app runs smoothly even on a 3G connection. For betting on limited bandwidth, you can switch on Lite Mode.
Get notified only about the games or matches you care about. You can turn off unnecessary notifications anytime.
Menus, buttons, help text — everything is in Bangla. No foreign-language interface to navigate.
