Everything You Need to Know About the 21st App

Smartphone usage in Bangladesh is growing every day, with most people now accessing the internet from their mobile devices. With this in mind, 21st has built its mobile app not just as a simple application, but as a complete gaming experience that fits right in your pocket.

One of the biggest advantages of the 21st app is that it's entirely in Bangla. From the menus to game rules, payment processes to support chat — everything is in your native language. For the many users in Bangladesh who aren't comfortable in English, the 21st app is a game-changer.

Important Information for Android Users

Installing the 21st app on Android requires an APK file, as it is not available on the Google Play Store. There's no need to worry — installing an APK is completely safe as long as it's downloaded directly from 21st's official site. Our APK is regularly checked using VirusTotal and other security tools.

To enable Unknown Sources, open your phone's Settings, then go to the Security or Privacy section and turn on "Install Unknown Apps" or "Unknown Sources". This only needs to be done once — you won't need to repeat it for future app updates.

Account Management in the App

Once logged in to the 21st app, your dashboard brings everything together in one place — wallet balance, betting history, active bonuses, deposits, and withdrawals, all clearly displayed. Every transaction is recorded and can be checked at any time.

Biometric login is one of the 21st app's standout features. Once set up, you'll never need to type your password again — just place your finger or glance at your phone to log in instantly. It's not only convenient, it's an extra layer of security.

In-App Payments — Easier & Faster

BKash and Nagad payments on the 21st app are faster than on the website. The app can securely save your payment details, so you don't have to re-enter them every time. Just hit the Deposit button, enter the amount, and confirm — your funds are added in three simple steps.

21st is committed to keeping the app continuously updated. New games, new features, and security patches roll out on a regular basis. Update as soon as you receive a notification — that's the best way to get the full experience.

Important Note

Only download the APK from 21st's official site. Downloading from other sources may put you at risk.

App Download Bonus

Get an extra 10% bonus on your first deposit made through the app — a special offer exclusively for app users.
