These Terms form a legal agreement between the user ("you" or "member") and the ck644 platform. By accessing the site, creating an account, or using any service, you agree to all of these terms. If you do not agree with any part of these terms, please refrain from using the site.
ck644 reserves the right to amend, modify, or update these terms at any time without prior notice. Continued use of the site after revised terms are published will be considered acceptance of the new terms. Please review this page regularly.

- Do not share or give your login details to anyone else.
- If you notice any suspicious activity on your account, notify ck644 support immediately.
- ck644 will not be held responsible for losses resulting from unauthorized third-party access, unless it is proven that there was a fault in the platform's own security systems.
ck644 uses SSL encryption to keep all data secure. However, it is not possible to fully eliminate the inherent risks of internet use, so members must also exercise their own caution.
Deposits & Withdrawals
4.1 Deposit Rules
Funds can be deposited on ck644 only through the following approved payment methods:
- Minimum deposit amount: ৳300 (per method).
- The name and number provided at the time of deposit must match the details on your ck644 account.
- Deposits made through third parties are strictly prohibited.
- After verification, deposited funds are generally added to the account within a short time.
4.2 Withdrawal Rules
- Minimum withdrawal amount: ৳800.
- Withdrawals are processed only via the same method used for the deposit.
- Successful withdrawals are generally completed within 5 to 30 minutes.

Bonuses & Promotions
5.1 Welcome Bonus
New members on ck644 receive a 150% bonus on their first deposit, up to ৳15,000. For example, depositing ৳1,000 gives a ৳1,500 bonus for a total balance of ৳2,500; depositing ৳22,000 or more gives the maximum ৳15,000 bonus, for a total of ৳37,000.
5.2 Wagering Requirements
Wagering requirements must be met to withdraw bonus funds. Wagering is calculated on the bonus amount only, not the deposit amount. Example: ৳1,500 bonus × 15 = ৳22,500 must be wagered before winnings from the bonus can be withdrawn.
