Troubleshooting

Common Issues & Quick Fixes

Most issues are covered here — check before contacting support

Start by checking your internet connection. Then make sure your username and password are correct — pay attention to whether Caps Lock is on. If you're still having trouble, use the "Forgot Password" option. If that doesn't resolve it, reach out to us via live chat.

Deposits via bKash or Nagad typically arrive within 5 minutes. If yours is delayed, contact our support team with a screenshot and transaction ID. For bank transfers, please allow up to 24 hours.

The most common reasons for a rejected withdrawal are incomplete KYC, unmet bonus wagering requirements, or incorrect payment details. A full explanation will be sent to your email. If you're unsure what went wrong, reach out via live chat.

To install the APK on Android, enable "Unknown Sources" under Settings > Security. On iOS, download directly from the App Store. If installation fails, restart your phone and try again.

If you haven't received your bonus, first check that all conditions are met — such as the minimum deposit amount and correct promo code entry. Some bonuses can take up to 30 minutes to credit automatically. If it still hasn't appeared, contact support.

Clear your browser cache and cookies, then try again. On mobile, close the app and reopen it. If Live Casino games are freezing, switch to a WiFi or 4G connection for a more stable experience.

For security reasons, too many incorrect password attempts will automatically lock your account. Use the link sent to your email to unlock it, or contact support to verify your identity and restore access.

KYC verification is usually completed within 24 hours of uploading your national ID and selfie. During busy periods, it may take up to 48 hours. Uploading clear images in the correct format will speed up the process.
