3999 b FAQ — All your questions answered here

Each person may only open one account. Attempting to create multiple accounts using the same mobile number or device may result in all accounts being suspended. This policy is strictly enforced to maintain a fair gaming environment.

After logging in, go to "Profile Settings" on your dashboard to update your name, email, and payment details. Changing your mobile number requires OTP verification. For security purposes, you will need to enter your current password when setting a new one.

Regular games don't require additional verification. However, large withdrawals may require identity verification — this is entirely for your protection, to prevent anyone else from withdrawing funds from your account.

On the login page, click the "Forgot Password?" link. Enter your registered mobile number and request an OTP. Verify your identity using the 6-digit code sent to your mobile, then set a new password. The entire process takes under 2 minutes.

The following payment methods are currently accepted at 3999 b:

• Mobile Banking (Personal & Agent)
• Nagad (Personal & Merchant)
• Rocket (Dutch-Bangla Mobile Banking)
• USDT (TRC20 and ERC20 networks)

Mobile Banking, Nagad, and Rocket deposits are typically credited within 5 minutes. USDT deposits depend on network confirmations and usually take 10–30 minutes. If more than 30 minutes have passed, please contact support with your transaction ID.

3999 b does not charge any deposit fees. However, Mobile Banking or Nagad may apply their own transaction charges, which are set by the respective service providers. These charges are generally very small.

Standard withdrawal requests are processed within 5–15 minutes. During peak hours or for large amounts, processing may take up to 24 hours. VIP members receive priority processing.
