Account & Registration

Registering on 666kk is quick and simple. Just follow the steps below:

  • Verify your number using the OTP code sent to your mobile.
  • Once registration is complete, you can log in to 666kk right away.
The entire process takes just 2 minutes.

Each member is allowed to register one account only. Opening multiple accounts violates 666kk's terms and conditions and may result in permanent account suspension. To keep the playing field fair for everyone, we ask all members to use a single account.

After logging in, go to "Account Settings" and select the "Change Password" option. Enter your current password and your new password. For security, use a password of at least 8 characters that includes numbers, letters, and special characters.

On the login page, click "Forgot Password?". Enter your registered mobile number and an OTP will be sent to you. Verify the OTP and set your new password. The entire process takes under 5 minutes.

Deposits & Withdrawals

666kk supports a variety of payment methods:
  • Mobile Banking (Various Popular Services)

  • Cryptocurrency (USDT, BTC, etc.)
Deposits through all methods are typically credited to your account within 1–15 minutes.

The minimum deposit on 666kk starts at just BDT 300, making it accessible for most players in Bangladesh. The minimum withdrawal amount is also kept low so any member can easily cash out their winnings. Check the deposit page for exact figures.

Most withdrawals are processed within 15 minutes to 2 hours. Your first withdrawal may require KYC verification, but once that's done, future withdrawals will be faster. Bank transfers may take 1–3 business days.
