Account & Registration

To register at www3666, you'll need your mobile number or email address, a strong password, and your full name. You must be 18 or older. You may later be asked to provide your national ID or passport details for account verification.

No. Under www3666's policy, each person may only hold one account. Creating multiple accounts using the same mobile number, email address, or device may result in all accounts being suspended and any accumulated balance being forfeited.

Verification is not required to start betting, but KYC verification must be completed before making a withdrawal. You'll typically need to upload photos of the front and back of your national ID along with a selfie. The process is usually completed within 24 hours.

Click the "Forgot Password?" link on the login page. Enter your registered mobile number or email and an OTP will be sent to you. Use that code to set a new password. The OTP expires in 10 minutes, so use it promptly.

Your new password must be at least 8 characters long. Including uppercase letters, numbers, and special characters is strongly recommended.

First, make sure Caps Lock is off and that you're entering your password correctly. Clear your browser cache and try again. If the problem continues, use the password reset option. Multiple failed attempts may temporarily lock your account — contact support if that happens.

Betting Rules

www3666 offers betting on over 30 sports, including cricket, football, kabaddi, hockey, tennis, and badminton. Cricket and football have the widest range of markets for Bangladeshi users. In the live betting section, you can place bets in real time while a match is in progress.

www3666 uses decimal odds. For example, odds of 1.85 mean a ৳100 bet returns ৳185 in total (your original ৳100 plus ৳85 in profit). The formula is simple: stake × odds = total return. Visit the betting analysis page for a more detailed guide.

Once a bet is confirmed, it generally cannot be changed or cancelled. However, www3666's Cash Out feature lets you partially or fully cash out a bet during a live match under certain conditions. Cash Out may not be available for all matches.

If a match is cancelled or abandoned, www3666 will generally refund the stakes on all bets placed for that match. The amount is automatically credited back to your account balance. For parlay bets, the cancelled leg is counted as odds of 1.0.
