Frequently Asked Questions

Here you'll find answers to the questions ok99 users ask most. Click on any question to expand the answer.

Account & Profile

To update your profile on ok99, log in first and click your profile icon at the top right of the screen. From there, go to "My Profile" or "Account Settings." You can change your name, email, address, and date of birth from this section.

Changing your mobile number is a different process, since it serves as your login ID. You cannot update your registered mobile number on your own — you'll need to contact ok99's customer support to do so. The support team will verify your identity (by matching your National ID or registration details) before initiating the change. The number is typically updated within 24 hours. You can submit this request via Live Chat or by emailing support@ok99.biz. Please note that strict verification is required for security purposes — this is to protect your account.

No, ok99 strictly allows only one account per person. Attempts to create multiple accounts using the same mobile number, the same National ID, or the same device are automatically detected by the system.

If someone is caught with multiple accounts, all of them will be closed simultaneously and any bonuses or winnings held in those accounts may be forfeited. This policy exists to prevent abuse of the bonus system and to ensure a fair environment for all members. If two members of the same household want to play from the same device, it's best to notify ok99 Support in advance — they will assess the situation and decide accordingly.

Interface & Mobile App

If the ok99 app won't open or keeps crashing, try the following steps one by one:

1. Check your internet connection: Check that your mobile data or Wi-Fi is active. Try opening another page in your browser to confirm your connection is working.

2. Update the App: Older versions of the ok99 app can be unreliable. Download the latest version from the ok99 app page, uninstall the old one, and install the new version.

3. Clear cache: Go to your phone's Settings > Apps > ok99 > "Clear Cache."

4. Restart Your Phone: In many cases, simply restarting your phone will resolve the issue.

5. Free Up Storage: If your phone has less than 1 GB of free storage, the app may crash.

If the problem persists after trying all of the above, contact ok99 via live chat and share your phone model and Android version — the technical team will get it sorted quickly.
