Read through the sections below step by step or go directly to the section you need.
Section 1
Account Related Questions
Opening an account at c366 is very simple. Go to the c366 Login page and fill out the registration form — you'll need to provide your mobile number, a preferred username, and a strong password. Once you submit your details, your account will be activated immediately and you can start playing right away. Keep in mind, each player can only have one account.
If you forget your password, click the "Forgot password?" option on the login page. Enter your registered mobile number or email and a verification code will be sent to you. After confirming your identity with the code, you can set a new password. If you have trouble completing the process, contact c366 support — 24/7 live chat is always available.
There are a few common reasons for login issues: wrong password, Caps Lock being on, or an outdated browser cache. First, refresh your browser and clear the cache. If your password is correct but you still can't log in, your account may be temporarily locked — in that case, reaching out via live chat will get it sorted quickly.
Your username must be unique, and it's a good idea to mix letters and numbers. Your password should be at least 8 characters long and is most secure when it combines uppercase and lowercase letters, numbers, and special characters. Avoid simple passwords like "12345678" or "password". Never share your password with anyone.
No, under c366's rules each player can only hold one account. If a person is found to have multiple accounts, those accounts will be closed and the balances in them may be forfeited. All benefits, bonuses, and VIP perks are available through a single account — so there's no need for more than one.
Section 2
Account Verification
The name on your c366 account must exactly match the name on the mobile wallet (bKash, Nagad, or Rocket) you use. This is to make sure no one else can withdraw money from your account. If the names don't match, your withdrawal may be blocked, so it's important to enter the correct name from the start.
If your verification is rejected, first understand the reason — it usually happens when the document image is blurry, cut off, or expired. Take new, clear photos and resubmit. If the issue continues, speak with the support team via live chat — they're ready to help in Bengali and will clearly let you know which documents are needed.
c366 uses SSL encryption to keep all data secure. Your identity card or other documents are used only for verification purposes and are not shared with any third party. Under c366's privacy policy, your personal information is stored with the highest level of protection. Visit the privacy policy page for more details.
Account verification is done for two main reasons: first, it confirms that you are who you say you are and that no one has opened a fake account in your name. Second, it ensures secure transactions — especially at the time of withdrawal. Once verification is complete, all future transactions become much faster and hassle-free.
A National ID card (NID) is the most commonly used document for identity verification. A passport or driving licence may also be accepted. You'll need to submit clear photos of both the front and back of the document, where the name, date of birth, and photo are clearly visible. The support team will confirm whether a particular document is acceptable.
Section 3
Withdrawal Rules and Process
The minimum withdrawal from c366 is ৳500. Requests below this amount will not be processed. For deposits, however, you can start with as little as ৳300. You can withdraw to bKash, Nagad, or Rocket — any one of them — but the wallet name must match the name on your c366 account.
Withdrawals from c366 are generally completed within 30 minutes to 3 hours. Most requests are processed within that window. There may be a slight delay during busy periods, but if it takes longer than that, ask via live chat — the support team will let you know the status of your request.
No, under c366's security policy withdrawals can only be made to a wallet registered in your own name. Withdrawal requests to another person's bKash, Nagad, or Rocket number are not processed. This rule is in place to prevent fraud and unauthorized transactions. So at the time of registration, use a wallet number that is in your own name.
If a withdrawal has been "Pending" for more than 3 hours, first confirm that your account is verified and that the wallet name matches the name on your account. If the issue still isn't resolved, contact live chat and provide the withdrawal reference number — the support team will review the request promptly.
Winnings from a bonus can be withdrawn only after the wagering requirement for c366's welcome bonus has been met. For example, if you receive a ৳1,000 bonus, you'll need to wager 20 times that amount — meaning ৳20,000 in bets. Keep in mind, wagering is counted only on the bonus amount, not on the deposit. Once the requirement is met, the balance automatically becomes withdrawable.

Questions About Slot Games
RTP, or Return to Player, is the average percentage of total bets that a slot game returns to players over the long run. For example, a game with a higher RTP theoretically pays back more. Keep in mind, though, that RTP is an average across billions of spins — it doesn't apply directly to a single session. Every spin is completely independent.
Volatility, or risk level, describes how often and how large the rewards are in a slot game. High volatility games offer bigger rewards but less frequently — these are better suited for patient players. Low volatility games pay out smaller rewards more often — they're better for playing longer on a smaller budget. Which one you choose depends on your play style and budget.
If you want to play on a small budget, choose low or medium volatility slots — they pay out smaller rewards more frequently, so your balance lasts longer. Look for games with a low minimum bet. You'll find games suited to different budgets in c366's slots section. Set a specific limit before you start playing and don't go beyond it.
Many slot games are available in demo or free play mode, where you can understand the game's mechanics and features without using real money. Playing a bit in demo mode before trying a new game makes it easier to decide. You can see which games at c366 have demo mode directly in the game lobby.
Free spins are a feature where you get extra spins without any bet being deducted from your own balance. They are usually awarded when a special symbol (Scatter) lands a certain number of times within the game. Winnings from free spins may be subject to wagering requirements, so check the rules for each game once.

If your internet connection suddenly drops during a game, c366's system saves the state of that round. Once you reconnect, you can continue the game from where it left off.
