Mobile Betting — No laptop needed anymore

Just a few years ago, online betting meant sitting in front of a laptop or desktop. Times have changed. Smartphone usage in Bangladesh is growing fast, and most people now access the internet on their phones. With that in mind, 399 Casino has built a powerful mobile app designed for this reality.

Check pre-match odds on the bus to work, place your bets on the way back from the market, and bet while watching the live stream from the comfort of your home at night. The 399 Casino app is always with you.

The app is built with Bangladesh's internet conditions in mind. It runs smoothly on slow connections, and live betting works without lag even on a 3G network.

  • 24 hours a day, 7 days a week — bet whenever you want
  • Smooth performance even on slow networks
  • Data Saver Mode — Lower Data Usage
  • View previous results even while offline
