Why Players Trust ck644
Account & Registration
Registering on ck644 takes under two minutes. Open ck644.net in your mobile browser, tap the registration button, and enter your mobile number, a chosen username, and a secure password. You will receive a one-time SMS verification code to confirm your number. Once that code is entered, your account is active and ready for your first deposit. You must be 21 years or older to register — age is verified during KYC before your first withdrawal.
ck644 requires a valid government-issued photo ID to complete KYC verification. Accepted documents include your National Identity Card (NID), passport, or birth certificate. You will also need to upload a clear selfie holding your ID so our team can confirm the match. KYC reviews are typically completed within 24 hours. Completing KYC unlocks higher withdrawal limits and is mandatory before your first withdrawal is approved.
On the ck644 login page, tap Forgot Password and enter the mobile number linked to your account. A reset code will arrive via SMS within seconds. Enter the code, then choose a new password of at least 8 characters mixing letters and numbers. If you no longer have access to your registered mobile number, email [email protected] from your registered address and our team will guide you through manual identity verification before resetting access.
No — ck644 strictly permits one account per person. Duplicate accounts are flagged during KYC and are closed immediately, with any associated bonuses forfeited. If you accidentally created a second account, contact [email protected] right away to consolidate your records before our compliance system flags the duplication. Operating multiple accounts to claim bonuses more than once is a breach of our Terms and Conditions.
To permanently close your ck644 account, send a closure request by email from your registered address to [email protected]. Our team will verify your identity, process a withdrawal of any remaining balance, and close the account within 48 hours. If you are closing because gambling has become a concern, we strongly recommend requesting self-exclusion instead — it closes your account and also blocks re-registration for a minimum of 12 months, providing a stronger layer of protection.
Deposits & Withdrawals
bKash deposits on ck644 are credited instantly — funds usually appear in your account balance within 30 seconds of the bKash transaction being confirmed. There is no manual processing step for bKash; the system updates automatically. If your balance has not updated after 5 minutes, take a screenshot of your bKash transaction confirmation and send it to [email protected] with your account username for priority resolution.
The minimum deposit on ck644 is ৳200 BDT across all supported payment channels including bKash, Nagad, Rocket, and Upay. There is no maximum deposit limit for verified accounts, though single deposits above a certain threshold may trigger additional security checks in line with our KYC policy. We recommend using our in-account deposit limit tool to set a personal cap that keeps your gaming within budget.
The minimum withdrawal on ck644 is ৳500 BDT. Withdrawals to bKash and Nagad are typically processed within 1 to 3 hours during support hours (9 AM to 11 PM Bangladesh Standard Time). Rocket and direct bank transfer withdrawals may take up to 24 hours depending on the receiving institution. KYC must be complete before any withdrawal is approved. ck644 charges no withdrawal fees, though your payment provider may apply its own standard mobile money charges.
Yes — ck644 supports direct bank transfers for both deposits and withdrawals. Supported institutions include BRAC Bank, City Bank, Dutch-Bangla Bank (DBBL), Islami Bank Bangladesh (IBBL), and Sonali Bank, among others. Bank transfer deposits typically clear within 2 to 6 hours depending on your bank's processing schedule. For large transactions, bank transfer is often the most convenient option. Contact [email protected] for dedicated deposit account details.
Withdrawals on ck644 can be declined for several reasons: incomplete KYC verification, an active bonus with outstanding wagering requirements that must be cleared first, a withdrawal request below the ৳500 minimum, or a mismatch between the name on your ck644 account and the name on your payment account. In all cases the funds remain safely in your balance and a reason is provided. Send your transaction ID to [email protected] for a specific explanation and fast resolution.
Games & Gameplay
ck644 covers a wide range of cricket betting markets across BPL (Bangladesh Premier League), IPL, T20 World Cup, ICC tournaments, and bilateral Test and ODI series involving the Bangladesh Tigers. Available markets include match winner, top batsman, top bowler, total runs over or under, method of first wicket, player of the match, and live in-play betting with ball-by-ball odds updates. Pre-match and in-play markets are both available on the ck644 cricket betting page.
Yes — all games on ck644 use certified Random Number Generator (RNG) technology ensuring every outcome is entirely random and independent of previous results. Games are supplied by verified providers including Pragmatic Play, Evolution Gaming, Spribe, and Ezugi, all of whom hold third-party RNG certifications. RTP (Return to Player) percentages are published for each slot title and can be found in the game information panel before you start playing.
Yes — ck644 is fully optimised for mobile browsers and requires no app download at all. The platform runs smoothly on Android (Chrome) and iOS (Safari) without any installation. Open your browser, go to ck644.net, and log in. Every feature — bKash deposits, live cricket betting, slots, fishing games, and live casino — is available directly in the browser. The site loads quickly even on standard 4G connections common across Dhaka, Chittagong, Sylhet, and the rest of Bangladesh.
ck644 offers a full live casino suite powered by Evolution Gaming and Ezugi, including Live Baccarat, Live Roulette, Live Blackjack, Live Dragon Tiger, Andar Bahar, and popular game shows such as Crazy Time and Lightning Roulette. Every live table streams in real time with professional dealers. Minimum and maximum bet limits vary by table and are displayed before you take a seat. Rules for each game are accessible via the information icon inside the game interface.
Aviator on ck644 is a multiplier-based crash game by Spribe. A plane takes off and a multiplier climbs from 1x upward — place your bet, then cash out before the plane flies away. If you cash out at 3x, your stake is multiplied by 3. If the plane crashes before you cash out, your bet is lost. The crash point is determined by a provably fair RNG algorithm that neither ck644 nor Spribe can influence. Auto cash-out and auto bet features are available in the game settings panel.
Bonuses & Promotions
ck644 offers new Bangladesh players a welcome bonus on their first deposit. The exact bonus percentage and maximum amount are shown on the promotions section of the site and are updated periodically to reflect current offers. To claim the welcome bonus, complete registration, make your first deposit, and opt in when prompted. Always review the current bonus terms on the promotions page before depositing — wagering requirements, eligible games, and expiry dates all apply.
A wagering requirement (also called rollover) is the number of times you must bet the bonus amount before you can withdraw bonus-derived winnings as real cash. For example, a ৳1,000 bonus with a 10x wagering requirement means you must place ৳10,000 in total qualifying bets before that bonus converts to withdrawable funds. Your progress is tracked in real time in the Bonuses section of your ck644 account. Slots typically count 100% toward rollover; live casino games may contribute at a lower rate — always check the specific bonus terms.
No — bonus funds and any winnings generated from bonus play cannot be withdrawn until the full wagering requirement is met. Requesting a withdrawal before rollover is complete will result in the bonus and its associated winnings being forfeited; only your original real-money deposit balance will be released. You can voluntarily forfeit an active bonus from the Bonuses section of your account at any time if you prefer to withdraw your real-money balance without waiting to complete the wagering requirement.
Yes — ck644 regularly includes free spins as part of welcome packages, reload bonuses, and seasonal promotions tied to events such as Eid, Pohela Boishakh, and BPL season. Free spins are credited to specific slot games noted in the promotion terms and expire after a set number of days. Winnings from free spins are subject to the wagering requirement stated in that promotion. Check the active promotions page on ck644 for the latest free spin offers available to Bangladesh players.
Log in to your ck644 account and go to My Account, then select the Bonuses tab. This page shows all active bonuses, their expiry dates, current wagering progress expressed as an amount completed versus total required (for example ৳4,200 of ৳10,000), and which games are eligible for each bonus. Expired bonuses appear in your bonus history. If the displayed progress does not match your betting activity, contact [email protected] with your account ID and a list of recent bet references for investigation.
Safety & Responsible Gaming
ck644 is a safe and reliable platform built with 256-bit SSL encryption to protect all player data and financial transactions. Your personal information is never sold to third parties, and all payment processing runs through secure encrypted channels. ck644 enforces KYC verification, age checks, and player protection tools as part of its responsible gaming policy. Players across Dhaka, Chittagong, Sylhet, Khulna, and Rajshahi use ck644 regularly for cricket betting and online casino gaming with confidence.
The minimum age to play on ck644 is 21 years old, and this requirement is strictly enforced. All players must complete age verification as part of the KYC process before their first withdrawal is approved. Any account found to belong to a person under 21 will be closed immediately and any funds returned. If you share a device with younger household members, please use parental control software to prevent access to gaming platforms including ck644.
Deposit limits, daily loss limits, and session time limits can all be set directly in your ck644 account under Settings, then Responsible Gaming — no support contact is needed and limits take effect immediately. For self-exclusion, which closes your account and blocks re-registration for a minimum of 12 months, email [email protected] from your registered address with the subject line Self-Exclusion Request. Self-exclusion is processed within 24 hours. A shorter cooling-off period of 24 hours up to 90 days is also available in account settings.
ck644 uses 256-bit SSL encryption on all data transmission between your device and our servers — the same standard used by major international banks. Your payment credentials such as your bKash PIN or bank account details are never stored on ck644 servers; transactions are handled entirely by the respective payment provider. Personal data is stored on secure servers with access controls, and our privacy policy strictly prohibits sharing your information with third parties without your consent except where required by applicable law.
If gambling is negatively affecting your finances, mental health, or relationships, act now rather than waiting for it to get worse. Log in to your ck644 account and immediately set a deposit limit or cooling-off period through the Responsible Gaming section of account settings. For a full break, email [email protected] to request self-exclusion — our team handles all such requests with complete confidentiality and no judgment. Talking openly with a trusted friend or family member about gambling concerns is often the most important first step toward regaining control.
