Mobile access in three steps

We run the platform through your phone browser, so there's no app store download and no install size to manage. Open the site from Chrome or Safari, sign in once, and the browser remembers your session. Add the page to your home screen if you want a one-tap shortcut. Biometric unlock activates after the first login — from then on, fingerprint or

face recognition takes you straight to the lobby. Deposits through bKash, Nagad, Rocket work the same way they do on desktop, and your betslip syncs across devices so you can start a bet on your phone and finish it on a laptop.

  • Open the site — Visit F21 Site from Chrome, Safari, or your default browser. The mobile layout loads automatically when the site detects a phone screen.
  • Sign in securely — Enter your account credentials or use the OTP sent to your mobile number. The browser saves your session so you stay logged in between visits.
  • Enable biometric unlock — After the first login, go to account settings and turn on fingerprint or face unlock. Next time you open the site, one tap takes you to the lobby.

APP FEATURES

Built for speed and one-handed control

We shaped mobile access around Bangladesh habits — quick logins, thumb-reach layout, wallet shortcuts that load your last-used payment method first. Every feature below cuts friction between opening the app and placing a bet.

Biometric login Fingerprint or face unlock replaces your password after the first session. Open the app, tap once, and you're in the lobby — no typing on a moving bus.
Push notifications Get alerts when your betslip settles, a live table opens, or the slot feature you triggered pays out. Turn notifications on from account settings to track results in real time.
Dark mode The interface switches to dark mode after sunset or when your device does. Easier on the eyes during late sessions, and it saves battery on OLED screens.
Offline lobby preview Game thumbnails and provider filters cache locally so you can browse slots even when signal drops. Tap a title and it loads when connection returns — no need to search again.

Quick deposit tiles surface bKash, Nagad, Rocket at the top of every screen so you can fund a bet without drilling through menus. Dark mode

switches on automatically after sunset, and the offline lobby preview caches game thumbnails so you can browse slot titles and provider filters even when signal drops. It's built for the commute, the lunch break, the wait at the airport.
