The ko99 app is now available on both Android and iOS. Slots, Live Casino, Sports Betting — all in one place, in Bengali, right in the palm of your hand.

This app is optimized for Bangladesh's network conditions and runs smoothly even on limited data. Live Casino video streams without interruption even on a 3G connection. The ko99 app interface is fully in Bengali, making it far more comfortable for users who aren't at ease with English.
Once you log in to the app, your full game history, balance, and bonuses are all visible on one screen — no digging around. Keep notifications on and you'll hear about new promotions and bonuses the moment they go live.
