First Deposit Tips
Always enter the reference number provided by 666c correctly when making a deposit — without it, your funds may take longer to credit. Also, deposit from the same mobile number you used to register; using a different number can cause delays.

What to know before you register

Signing up at 666c is straightforward, but knowing a few things from the start can save you trouble later. Most importantly — all the information you provide must be accurate and your own. Using a family member's name or a friend's number to register can cause issues when you try to withdraw.

Your mobile number is especially important because deposits and withdrawals are linked to the bKash or Nagad account registered under that number. Make sure the number you provide is your own and currently active — the OTP will be sent there.

Take your password seriously. Avoid simple combinations like "123456" or your birth year. Use at least 8 characters with a mix of uppercase and lowercase letters and numbers. Enabling 2FA after registration adds an extra layer of security to your account.

Each person may only register one account at 666c. Two members of the same household may hold separate accounts — however, multiple accounts on the same device will trigger a system alert. If your previous account was closed for any reason, please contact support before opening a new one.

If you have a referral code, enter it during registration — it cannot be added later. If a friend or someone you know is already a 666c member, using their code benefits both of you. You'll still receive the welcome bonus even without a code.

FAQ

Answers to some of the most frequently asked questions about payment methods and parlay bets.

666c supports all of Bangladesh's most popular mobile banking methods. bKash, Nagad, and Rocket offer the fastest and most convenient way to deposit, with a minimum of ৳500 and zero deposit fees. Bank transfers are also available — you can send from major banks including Sonali Bank, Dutch-Bangla, and BRAC Bank, though the minimum is ৳2,000 and processing can take 1–4 hours. Mobile banking deposits typically reflect within 5–15 minutes. One important thing to keep in mind: always use the reference number or recipient number found in the 666c cashier section. Sending without the reference or to the wrong number will require manual crediting and cause delays. You must deposit from your own mobile banking account — deposits from third-party numbers are not permitted.

A parlay, or accumulator bet, is a single bet that combines multiple matches or events. All selections must win for you to collect — but the rewards can be substantial. On 666c, this is available as a "parlay" or "multi bet." For example, say you pick three football matches: Team A wins Match 1 (odds 1.8), Team C wins Match 2 (odds 2.1), and Match 3 ends in a draw (odds 3.4). Combined as a parlay, the total odds are 1.8 × 2.1 × 3.4 = 12.85. A ৳500 bet would return ৳6,425 if all three come in. However, if even one result is wrong, the entire bet is lost. To place a parlay, go to the Sports section and click on your chosen odds one by one — the parlay option will appear automatically in the bet slip. Enter your stake and the slip will show your potential winnings. A single parlay can typically include up to 10–15 selections. The minimum parlay stake matches the standard sports minimum — ৳100.
