Why Choose the big321 App?

Faster Loading

The big321 app uses optimised WebView technology to load pages faster than a regular browser, especially on Malaysia's 4G networks.

Real-Time Notifications

Get notifications straight to your phone — from new promotions and match results to deposit and withdrawal updates on your big321 account.

Easy Login

Fingerprint support and saved login sessions let you access your big321 account with a single tap — no need to type your password every time.

Direct MYR Transactions

Deposits and withdrawals in MYR (RM) can be done directly from the app — FPX, e-wallets, and other local payment methods are fully supported.

  2. Go to Security or Privacy.
  3. Enable the option Install Unknown Apps or Unknown Sources.
  4. On Android 8.0 and above, you may need to grant special permissions to the browser or file manager you're using to open the APK.
Minimum System Requirements
  • Operating system: Android 6.0 (Marshmallow) or above
