It's completely normal to feel unsure when you're new to any online platform — how to open an account, where to send money, how to use a bonus. The ko77 Help Center was built to answer exactly these questions, in plain, simple English.
Ko77's support team is available around the clock. Live chat responses typically come within 5 minutes on average.
Mobile payments in Bangladesh have never been easier. Mobile Pay and Nagad are already on almost everyone's phone, and you can use these familiar methods to deposit and withdraw on ko77 — no separate bank account needed. That said, small issues can still come up, like entering the wrong transaction ID or sending a payment to the wrong number. In those cases, the ko77 support team is ready to resolve things quickly.
Forgetting your password happens to everyone. Resetting it on ko77 is quick and easy. On the login page, click the "Forgot Password?" link, enter your registered mobile number, and use the OTP you receive to set a new password. The whole process takes under 2 minutes.
Ko77 will never ask for your password or OTP via email or SMS. If anyone requests this information, it may be a scam — stay alert.
Bonuses can be confusing, but here's how it works: to claim ko77's welcome bonus, you need to place a certain amount of bets after your first deposit. Once the wagering requirement is met, the bonus funds become available for withdrawal. Full terms and conditions can be found in the Bonus section of the Help Center.
Many users run into trouble downloading the app. On Android, you need to install the APK file directly since betting apps are restricted on Google Play. To do this, go to your phone's settings and enable the "Unknown Sources" or "Install Unknown Apps" option. The ko77 Help Center has a full step-by-step guide with screenshots, covering all Android devices.
For Live Casino issues — such as a game disconnecting mid-session or connection problems — ko77 follows a policy of automatically refunding your bet. To report an issue, provide the game ID and time via the support chat.
