Category 1
Security and Privacy
ck 77 uses SSL (Secure Socket Layer) encryption, which fully encrypts your login details, payment data and personal information before sending it. This means third parties cannot read that data. When you see "https" and a padlock icon in your browser's address bar, your connection is secure. For details on how data is stored and used, see our Privacy Policy.
A strong password should have at least 10 characters — a mix of uppercase and lowercase letters, numbers and special characters (#, @, !). Avoid simple passwords like "123456" or your date of birth. Do not use your ck 77 account password on any other site. Make a habit of changing your password every few months.
If you suspect an unauthorized login, change your password immediately. Then contact ck 77's 24/7 live chat — they can check your account activity. If needed, request a temporary account lock. Log out any active sessions on other devices. For more information about logging in, visit the ck 77 Login page.
Never. No ck 77 staff member will ever ask for your OTP, bKash PIN, Nagad PIN or password — not by phone, message or chat. If anyone asks for these, it is an attempt at fraud. If you receive any such suspicious contact, report it to live chat immediately. Keep your PIN and OTP completely private.
The only official ck 77 address is ck-77.cam. Any other domain — such as "ck77.com", "ck-77.net" or anything similar — may be fake. Always type the address directly into your browser or open it from a bookmark. Before clicking any link received via message or social media, check the address carefully. The genuine site will always show "https" and a padlock in the URL bar.
Public Wi-Fi networks are generally less secure and carry a higher risk of data theft. When logging in to ck 77 or making transactions, use your own mobile data or a trusted home network. If you have no option but to use a public network, you may use a reliable VPN. Remember to log out after completing your transaction.

Bonus Terms & Conditions
Every bonus at ck 77 has a set expiry period, which starts from the day the bonus is credited. If the wagering requirement is not met before the expiry date, the bonus and any associated winnings are cancelled. The expiry period for each bonus is clearly shown when you claim it. Complete the requirements before time runs out.
Wagering means you must place bets totalling a specific multiple of the bonus amount. For example: for bonuses other than cashback or the welcome bonus, only the bonus amount itself is multiplied — not the deposited amount. The welcome bonus wagering is 20x: if you deposit ৳1,000 and receive a ৳1,200 bonus, you must wager ৳1,200 × 20 = ৳24,000. This requirement must be met before bonus winnings can be withdrawn.
After opening a new account, ck 77 automatically credits a 120% bonus, up to ৳20,000 on your first deposit. The minimum deposit is ৳200. Example: depositing ৳33,400 gives you a ৳20,000 bonus, bringing your balance to ৳53,400, with a wagering requirement of ৳20,000 × 20 = ৳4,00,000. No separate code is needed to receive this bonus. Join ck 77 Casino and enjoy it right away.
No. The ck 77 welcome bonus is available only once per new account — on the first deposit only. If the same person creates multiple accounts to claim the bonus more than once, both accounts risk being closed. This is part of ck 77's fair play policy and is detailed in the Terms & Conditions.
The ck 77 weekly reload gift can be claimed once per week on any deposit. You receive a 30% bonus on your deposit, up to ৳8,000. The wagering requirement is 18x. For example: deposit ৳2,000 and you receive a ৳600 bonus, with a wagering requirement of ৳600 × 18 = ৳10,800. The minimum deposit is ৳200. You may need to press the claim button to receive this bonus.
The Cricket Victory Bonus is intended for use on cricket and other sports markets before placing bets. You get a 40% bonus on your deposit, up to ৳10,000, with a 15x wagering requirement. Example: depositing ৳2,000 gives a ৳800 bonus, with wagering of ৳800 × 15 = ৳12,000. This bonus is especially useful during BPL or T20 World Cup. For more details, visit the Cricket Betting page.

Depositing Money
Log in to ck 77, go to the "Deposit" option and select bKash. Enter the amount you wish to deposit (minimum ৳200), then send money from your bKash app to the ck 77 bKash number shown on screen using "Send Money". Save the transaction reference number. Your balance is usually credited within a few minutes.
ck 77 does not charge any deposit fee itself. However, bKash, Nagad or Rocket may apply their own "Send Money" charges according to their own terms. Bank transfers may also carry internet banking charges that vary by bank. Check your payment provider's charges before making a deposit.
ck 77 currently supports five deposit methods: bKash, Nagad, Rocket, Upay and Bank Transfer (Dutch-Bangla Bank, BRAC Bank, and other major commercial banks). The minimum deposit is the same for all methods — ৳200. Cryptocurrency and international cards are not supported.
The minimum deposit at ck 77 is ৳200, and this applies to all payment methods. With ৳200 you can play any slot game, including Gates of Olympus, Fortune Tiger, and Aviator. If you want to play at higher stakes, depositing more is advisable, as each game has its own minimum bet limit.
First, wait 15–30 minutes. If it still does not appear, take a screenshot of the bKash or Nagad transaction and send it to ck 77's 24/7 live chat. Providing the reference number and transaction time will allow the support team to verify it quickly. If you sent money to the wrong number during the deposit, mention that as well.
The minimum withdrawal amount at ck 77 is ৳1,000. After submitting a withdrawal request, funds are generally delivered within 15 minutes to 2 hours via bKash, Nagad, Rocket, Upay or bank transfer. If the wagering requirement for a bonus has not been met, the withdrawal process will not begin — so make sure requirements are fulfilled before withdrawing.

VIP Benefits
ck 77's VIP program has three tiers: Bronze — up to 0.4% weekly cashback; Silver — up to 0.8% weekly cashback; Gold — up to 1.2% weekly cashback. Each tier comes with additional special benefits. For more details, visit the ck 77 VIP page.
In addition to weekly cashback, ck 77 VIP members receive special deposit bonuses, faster withdrawal processing, a dedicated account manager, and access to exclusive tournaments and events. The higher the level, the greater the benefits. Account verification must also be complete to receive a special birthday reward.
VIP level progression at ck 77 is based on regular play. The more active you are and the more betting activity you carry out, the sooner you can reach a higher level. Contact live chat to ask about the specific turnover or points requirements — the support team can tell you how your account is progressing.
Weekly cashback is calculated on your total net loss for that week — that is, total losses minus total winnings. For example: if a Silver member has a net loss of ৳20,000 in a week, they receive ৳20,000 × 0.8% = ৳160 in cashback. This is the maximum cashback amount at Silver level for that week. Cashback is credited every Monday.
ck 77 VIP weekly cashback has its own terms, which differ from the welcome bonus. Whether cashback is added directly to your balance or carries any conditions can be confirmed through live chat. Generally, cashback carries a much lower wagering requirement than the welcome bonus, which is beneficial for high-volume players.
Refer new members through the Refer a Friend offer — when the referred member completes their first deposit, you can receive up to ৳3,000 as a reward, with a 12x wagering requirement. This is part of the VIP programme. Contact ck 77 live chat to get your referral link or code. Each active member you refer can add to your rewards.
