Account FAQ

Opening an account on c667 is quick and completely free. Go to the registration page and enter your name, email, mobile number, date of birth, and password, then complete email verification. Your account will be active in as little as 3 minutes.

You must be at least 18 years old to register on c667. Age is verified during registration and confirmed via valid ID during KYC. Accounts belonging to users under 18 will be closed.

KYC (Know Your Customer) is the identity verification process required under international financial regulations. It must be completed before making any withdrawal. To complete KYC, please upload one of the following documents:
  • National ID Card (NID) – Both Sides
  • Passport – Information Page
  • Driving License – Both Sides
Verification is typically completed within 24–48 hours.

No. Under c667 policy, each individual is allowed only one account. If multiple accounts are found under the same person or the same ID, all associated accounts may be suspended and balances frozen.

On the login page, click the "Forgot Password?" link. Enter your registered email address. A password reset link will be sent within a few minutes. The link must be used within 24 hours.

Once KYC verification is complete, your account name cannot be changed. Your email address, however, can be updated from your profile settings — you will need to verify the new email address. Contact live chat for assistance.

To permanently close your account, contact our support team. Make sure to withdraw any remaining balance beforehand. For a temporary break, you can use the Cooling-Off or Self-Exclusion options under Responsible Gaming.
Deposits & Withdrawals

Payment FAQ

The minimum deposit on c667 is BDT 500. Limits may vary slightly by payment method. There is no maximum limit, though KYC verification is required for large transactions.

You can deposit on c667 using the following methods:
  • Mobile Banking
  • Bank Transfer
  • Internet Banking
  • Debit & Credit Cards
All methods credit your balance instantly or within a few minutes.

Withdrawals on KYC-verified accounts are typically processed within 15 minutes to 3 hours. Mobile banking is the fastest option. Bank transfers may take up to 24 hours. First-time withdrawals may require additional verification.

c667 does not charge any fees on withdrawals. However, your bank or mobile banking provider may apply their own transfer charges. Withdrawals from bonus funds require the wagering conditions to be met first.

Your balance is usually credited within 5–10 minutes. If it takes longer, contact c667 Live Chat with a screenshot of the payment or your transaction ID. Our team will resolve the issue promptly.

It is generally recommended to withdraw using the same method as your deposit. However, you can withdraw via a different method, in which case additional verification may be required. Contact Support for more details.

The maximum daily withdrawal limit depends on your account tier and verification status. Fully KYC-verified accounts have significantly higher limits. For exact figures, check your account settings or contact the Support team.

If your withdrawal is still being processed, it may be possible to cancel it through the Support team. However, once the transaction has been completed, it cannot be reversed.
Bonuses & Offers

Bonuses FAQ

A welcome bonus is automatically credited on your first deposit after opening a new account. Full details on the bonus amount and terms are available on the Promotions page. No special code is required during registration to receive the bonus.

Wagering Requirement is the wagering requirement that must be met before a bonus can be withdrawn. For example, 30x means you need to place bets totalling 30 times the bonus amount. Each bonus has its own terms — the details are always stated at the time of registration or in the bonus terms and conditions.

Every bonus has a set validity period (typically 7–30 days). If the wagering requirements are not met within that period, the bonus balance is automatically forfeited. Your original deposit is not affected by the cancellation.

You'll receive a referral bonus when someone registers and makes their first deposit using your referral link or code. Bonus amounts and terms are available on the Promotions page. Find your referral code in your account settings.

c667 offers weekly or monthly cashback to regularly active members. Cashback is credited automatically once you reach a certain wagering amount. Check the Promotions section of your account for current cashback offers.

Free spins can generally be used on specific slots games, as stated in the bonus terms. Any winnings from free spins are credited directly to your bonus balance and wagering requirements apply.
Games & Betting

Gaming FAQ

c667 offers over 500 games and betting options:
  • Sports Betting – cricket, football, tennis, badminton, and 20+ more sports
  • Live Sports Betting (In-Play)
  • Slots – 300+ Games
  • Live Casino – Roulette, Blackjack, Baccarat
  • Virtual Sports

c667 uses decimal odds. For example, odds of 2.50 mean a BDT 100 bet returns BDT 250 if you win (profit of BDT 150). Higher odds mean a less likely outcome but a bigger payout. Odds can change for each match.

Live Betting, or In-Play betting, means placing bets while a match is in progress. Odds change with every moment of the game, making it more exciting than standard pre-match betting – you can make decisions based on how the match is unfolding.

RTP (Return to Player) is the theoretical percentage of total wagers that a game returns to players over the long term. For example, an RTP of 96% means that, on average, BDT 96 is returned for every BDT 100 wagered. Most Slots on c667 have an RTP between 94% and 97%.

If a match is cancelled or the result is not determined, the bet is marked as void. In this case, the full stake is returned to your balance. If one leg of a multi-bet is voided, the bet is recalculated using the remaining legs.

The minimum bet is generally BDT 10. Maximum limits vary by event and market. For high-volume betting, please contact your account manager. Limits are displayed individually for each game or market.

Cash Out lets you withdraw part or all of your potential winnings before a match ends, helping you reduce risk. The Cash Out offer changes based on current market conditions and is not available on every match.
