Everyone wants everything at their fingertips these days — and gaming is no exception. Downloading the KB99 mobile app gives you an experience that goes beyond the website, because the app is purpose-built to take full advantage of everything your mobile device has to offer.
The first advantage is speed. Games load in the kb99 app an average of 40% faster than in a web browser, because certain game assets are cached within the app — so there's no waiting every time you load a game.
The second major advantage is security. The kb99 Android APK is completely safe — free from malware and adware. The file is distributed directly from our own servers, and every version is scanned by a third party.
The third advantage is push notifications. Updates on bonus offers, free spins, and special events are delivered straight to your phone — something that's hard to get on a browser.
The app is built with battery-optimized code, so your phone stays cool even during extended play sessions.
The app uses built-in image compression, reducing mobile data usage by 30% compared to the website.
Get instant notifications for jackpot bonuses, daily rewards, and new game releases.
Secure login with fingerprint and Face ID — no need to remember a password.
You might wonder — why isn't KB99 on the Play Store? The answer is straightforward. Online gaming apps in Bangladesh cannot be listed directly on Google Play due to its content policies. That's why KB99 distributes its app as an APK, which is entirely legal and safe. Thousands of users across Bangladesh install and use the KB99 app this way every day.
The latest version of the KB99 app (v3.2.1) comes packed with new features. Live Casino now streams in 4K quality, the Bingo room lets you manage up to 36 cards at once, and Fish Game graphics have been significantly improved. bKash and Nagad payments are also faster than ever.
KB99 has built a dedicated iOS app that fully adheres to Apple's Human Interface Guidelines. It runs seamlessly from iOS 12 all the way through the latest iOS 18, and is fully supported on iPad as well — making Live Casino even more enjoyable on a larger screen.
For those who prefer not to download an app or who like to play on PC, the kb99 web version is just as great. Open it in Chrome or Firefox for the full gaming experience. Even on a slow connection, the kb99 website runs smoothly thanks to our lightweight code.
KB99 releases app updates every month, bringing new games, bug fixes, and performance improvements. On Android, you'll see a notification to update as soon as one is available when you open the app. On iOS, make sure Automatic Updates is enabled under Settings → App Store.
