Mobile Usage
The ckk4 Android and iOS apps are available through official channels. From installing the app to connection issues — common questions about the ckk4 App are answered below.
The ckk4 Android APK and iOS app are both available through official channels. Downloading from any third-party source is not recommended, as those may not be safe. Using the latest version of the app ensures the best performance and security. Visit the ckk4 APK page to learn more.
ckk4 runs on Android 6.0 or above and iOS 12 or above. Having at least 2GB RAM and a stable internet connection keeps gameplay smooth. On older entry-level phones, slots and live casino games may take a little longer to load, but all core features remain usable.
When the connection drops, the ckk4 server saves the session state. In most cases, logging back in lets you continue from where you left off. In slot games, if the connection drops mid-spin, the result is determined server-side, so there is no chance of any discrepancy in your balance. In live games, rejoining takes you back to the table.
First, clear the app cache: go to your phone's Settings, find ckk4 in the App Manager, and tap "Clear Cache". Then close the app and reopen it. If the problem persists, install the latest version of the app. Switching to a Wi-Fi connection may load pages faster than mobile data.
Yes, ckk4 can be used fully from a mobile browser — Chrome, Firefox, or Safari. The website is mobile-responsive, so all the same features are available even without the app. However, using the native app gives you push notifications and faster loading.
Verification and Documents
Account verification is part of ckk4's security system. Here you will find detailed answers on which documents are needed, when they are requested, and how your information is kept secure.
ckk4 may ask for identity verification before your first large withdrawal, or if any unusual activity is detected on your account. This is done to protect your account and prevent unauthorised access to your funds. Verification may also be required to confirm that you are 21 or older.
A National ID card (NID) is the most accepted document at ckk4. A valid passport or driving licence may also be accepted. The photo of the document must be clear and legible — blurry or damaged images are not accepted. When uploading a document, it is best to provide photos of both the front and back.
ckk4 protects your personal information using SSL encryption. ID information is used only for account verification and is not shared with any third party. Our privacy policy contains full details on how data is stored and used.
If verification fails, first read the rejection reason carefully. Usually it happens when the photo is blurry or the document is expired. Take a clear photo in good lighting and submit again. If the problem continues, contact ckk4's live chat — the support team is active 24/7.
After registration you can normally start depositing and playing games. However, ckk4 may request verification before withdrawals above a certain amount. So keeping your documents ready right after registration avoids any delay when you withdraw later. Reading the Terms & Conditions will give you a better understanding of the full process.
Deposit Questions
bKash, Nagad, Rocket, Upay or bank transfer — you can easily deposit money into ckk4 using any of these methods. Common questions about deposits are answered below.
The minimum deposit amount at ckk4 is ৳500 — this limit applies to every method. Whether you use bKash, Nagad, Rocket, Upay or bank transfer, you must deposit ৳500 or more. The system does not accept transactions below ৳500.
Log in to ckk4, go to the deposit menu and select Nagad as the payment method. Send the amount to the designated mobile number and enter the transaction ID or reference number in the form. The balance is usually updated within a few minutes. Make sure you have enough balance and mobile data in your Nagad account.
ckk4 does not charge any processing fee on deposits. However, bKash may charge a fee on send money or payment transactions according to its own policy — that is bKash's own charge, not ckk4's. If you send to the correct payment number using the correct method, the full amount is credited to your ckk4 account.
First wait 5–10 minutes, as there may be a short delay during busy periods on bank or MFS networks. If the amount still has not been credited, contact ckk4's live chat or email with a screenshot of the transaction or the reference number. With the right proof, the support team will resolve it quickly.
Yes, bank transfer is one of ckk4's approved deposit methods. You can transfer from various Bangladeshi banks including Dutch-Bangla Bank, BRAC Bank and Islami Bank. Bank transfers may take a little longer, so save the reference number after making the transfer. The minimum amount here is also ৳500.
VIP Benefits
ckk4's VIP program is structured in three tiers — Bronze, Silver and Gold. Each tier comes with weekly cashback and various other benefits. Detailed questions about the ckk4 VIP program are answered below.
ckk4 VIP members receive cashback on their net losses every week. Beyond that, you get priority customer support, special promotional offers and more flexible limits. The range of benefits grows as you move to higher tiers. VIP status is applied to your account automatically.
The three VIP tiers and their weekly cashback rates are: Bronze — up to 0.4%, Silver — up to 0.8%, Gold — up to 1.2%. Cashback is calculated on the net loss for that week, which is total losses minus total winnings.
Cashback applies to the net loss for that week — meaning the rate for your tier is applied to what remains after subtracting total winnings from total losses. For example: if a Silver member's net loss for the week is ৳20,000, they will receive ৳20,000 × 0.8% = ৳160 in cashback.
At ckk4, you are automatically moved to a higher VIP tier based on your regular play and transactions. Although specific turnover thresholds are not published, staying regular and active will increase your tier over time. Your VIP tier progress can be seen from the account dashboard.
Once ckk4's VIP cashback is credited to your account, withdrawal is possible subject to meeting certain conditions. The wagering or other conditions applicable to cashback bonuses are detailed on the Terms & Conditions page. The minimum withdrawal amount is ৳1,000.
