Kau9 is not available directly on the Google Play Store, so you'll need to download and install the APK file manually. Follow the steps below.
Go to your phone's Settings > Security or Privacy and enable "Unknown Sources" or "Install Unknown Apps".
Download the Android APK file from the kau9 website. Once the download is complete, you'll find the file in your Downloads folder.
Tap the downloaded APK file. When the installation prompt appears, tap "Install".
Once installation is complete, open the kau9 app, log in to your account, and start playing.
Once the APK is installed, turn Unknown Sources back off — it's better for your phone's security. kau9's official APK is completely safe and virus-free.
IPhone and iPad users can install the kau9 app in two ways: directly from the App Store, or by adding it to the home screen as a PWA (Progressive Web App) via the Safari browser.
Visit kau9.net in Safari on your iPhone. Make sure to use Safari rather than Chrome or any other browser.
Tap the Share icon (an arrow pointing up from a box) in the bottom menu bar.
Tap "Add to Home Screen", enter a name, and tap "Add". The kau9 app icon will then appear on your home screen.
Everything the website offers is now at your fingertips. The kau9 app comes with exclusive mobile features.
Kau9 uses optimized code so games load fast even on a slow connection. You'll get a smooth experience on 3G as well.
Get instant notifications straight to your phone for new bonuses, live match kick-offs, and special offers.
Access your kau9 account instantly with a single touch using Fingerprint or Face ID — no password typing required.
Play Live Casino and Fish Games using your smartphone's full screen. The fullscreen experience on the app is far superior to the website.
Deposit to Mobile Banking, Nagad, or Rocket in just 3 taps from the app. Saved payment methods make transactions even faster.
Kau9 defaults to dark mode, which is easier on the eyes — especially when playing at night.
The number of online gaming apps in Bangladesh is growing fast, but not all of them deliver the same quality. Many apps turn out to be slow, prone to crashing, or lacking a Bangla interface. kau9 built its app with exactly these pain points in mind — every feature is designed specifically for players in Bangladesh.
One of kau9's biggest advantages is its size. At just 45 MB, the app runs smoothly even on low-storage phones. Many users in Bangladesh rely on 32 GB or 64 GB devices and keep a close eye on storage. kau9 understands that reality — the app is kept lightweight without cutting any corners on features.
Another key difference is offline support. The kau9 app can keep the main interface loaded even with a weak internet connection. You'll still need a connection to play games, but your account details, past transaction history, and game list are accessible offline.
Nearly all of the website's games are available on the kau9 app. Live Casino tables for roulette, baccarat, and blackjack, hundreds of slots variants, multiple fish game versions, and bingo — all neatly organized in the app. The Sports Betting section also features live odds for cricket, football, kabaddi, and more.
Kau9 releases regular app updates to keep the mobile gaming experience at its best. Each update brings new games, performance improvements, and minor bug fixes based on user feedback. If the app is already installed, you'll automatically receive notifications whenever a new update is available.
Yes, kau9 offers exclusive deals for mobile app users. These include mobile-only bonuses, app-exclusive tournaments, and extra cashback on your first deposit made through the app. These offers are reserved strictly for app users and are not available to those using the website.
The in-app customer support feature is genuinely useful. You can reach the support team via live chat directly within the app. If you run into a payment issue or spot a game error, you can report it instantly without leaving the app.
After installing, log in over Wi-Fi the first time — the initial data load will be much faster.
