All About the ko999 App

Mobile internet usage in Bangladesh keeps growing, with most people now spending far more time on smartphones than on computers. With that in mind, ko999 has built its mobile app as the top priority. Everything available on the website — live betting, casino games, payments, and bonus management — is fully accessible in the app, with no features left out.

A lot of members ask — if you can play in the browser, why bother downloading a separate app? The answer is simple. Logging in on the app takes no time at all, push notifications mean you'll never miss a big match or bonus offer, and the app's optimized code keeps things running smoothly even on a slow connection. Whether you're in Dhaka or somewhere with weaker network coverage, the ko999 app holds up.

What games are available on the app?

The ko999 app covers three main sections. First, Sports Betting — place bets on cricket, football, tennis, badminton, and over 30 other sports. All major tournaments are covered: BPL, IPL, Champions League, and Premier League. Second, Live Casino — play baccarat, roulette, blackjack, and Dragon Tiger with real dealers in real time. Third, Slots — choose from 500+ slot games, many with daily jackpots worth thousands of BDT.

"The ko999 app runs perfectly on my old Xiaomi phone. Logging in through the browser used to take forever — now I'm in within a second on the app."
— Mahmudul Hasan, Member from Rajshahi

How do I make payments through the app?

The ko999 app supports direct deposits and withdrawals via four mobile banking methods — bKash, Nagad, Rocket, and Upay. Go to the Payment section in the app, enter the amount and your mobile banking number, then confirm. Deposits typically arrive within 5 minutes, and withdrawals average 10–15 minutes.

How do I get app updates?

Ko999 releases regular app updates with new features and bug fixes. Android users can check for updates in the app's settings or download the latest APK from ko999.ws. For iOS users, simply refreshing Safari will automatically load the latest version.
