Section 1

Account & Registration

Everything you need to know about creating your cvk4 account, verifying your identity, managing login details, and account closure.

Creating a cvk4 account takes under two minutes. Visit cvk4.io, click the registration button, and fill in your mobile number, a secure password, and your date of birth. You must be 21 years or older to register. Once your details are submitted, a verification code is sent to your mobile number — enter it to activate your account and start playing.

cvk4 accepts the following identity documents for account verification: National Identity Card (NID), valid passport, or driving licence. You may also be asked to provide proof of address such as a recent utility bill or bank statement. Uploading clear, high-resolution images speeds up the review process. Most verifications are completed within 24 hours.

You can reset your cvk4 password by clicking "Forgot Password" on the login page and entering your registered mobile number. A one-time reset code will be sent via SMS. Enter the code, set a new password of at least eight characters, and log in. If you do not receive the SMS within a few minutes, contact support at [email protected].

No — cvk4 strictly allows one account per person. Duplicate accounts are a violation of the Terms and Conditions and will result in all accounts being suspended and any balances forfeited. If you accidentally created two accounts, contact support immediately to resolve the situation before any funds are at risk.

To permanently close your cvk4 account, email [email protected] from your registered email address with the subject line "Account Closure Request". Withdraw any remaining balance before submitting the request, as closure may take up to five business days to process. If you are closing your account due to gambling concerns, consider self-exclusion first — it may better suit your needs.
Section 2

Deposits & Withdrawals

All your questions about funding your account via bKash, Nagad, Rocket, and bank transfer — plus minimum amounts, processing times, and fees.

To deposit via bKash on cvk4, log in to your account, navigate to the Deposit section, and select bKash as your payment method. You will be shown a cvk4 agent number — send your desired amount to that number using the bKash app's Send Money feature, then enter the transaction ID on the cvk4 deposit page to confirm. Deposits are credited within minutes.

Nagad deposits on cvk4 are processed instantly in most cases — your account balance is updated within one to five minutes of a successful transfer. If your deposit has not appeared after ten minutes, check that you entered the correct transaction ID and contact support at [email protected] with the Nagad transaction reference for a manual review.

The minimum deposit on cvk4 is ৳200 for mobile banking methods including bKash, Nagad, Rocket, and Upay. For bank transfers via Dutch-Bangla Bank, BRAC Bank, IBBL, or Sonali Bank, the minimum is ৳500. There is no maximum deposit limit set by cvk4, though individual payment providers may apply their own transaction caps.

The minimum withdrawal on cvk4 is ৳500 for all supported payment methods including bKash, Nagad, and Rocket. Withdrawals to bank accounts such as Dutch-Bangla Bank or City Bank carry a minimum of ৳1,000. Your account must be fully verified before any withdrawal request can be approved — unverified accounts are limited to deposits only.

Withdrawals to bKash, Nagad, and Rocket are typically processed within one to four hours during business hours. Bank transfers to Dutch-Bangla Bank, BRAC Bank, City Bank, or Sonali Bank usually take one to three business days depending on the receiving bank's processing schedule. Withdrawals submitted over weekends or public holidays may take slightly longer.

cvk4 does not charge platform-side fees on standard deposits or withdrawals. However, your mobile banking provider — bKash, Nagad, or Rocket — may deduct a small service charge as part of their own fee structure. Check your provider's current rate schedule for details. Bank transfer fees, if any, are applied by the receiving bank, not by cvk4.

Games & Gameplay

Answers about cricket betting markets, slots, live casino, RTP, fair play certification, and playing on mobile devices.

cvk4 covers a wide range of cricket betting markets including match winner, top batsman, top bowler, total runs, man of the match, toss winner, and over/under run totals. In-play betting is available for BPL, IPL, T20 World Cup, ODI series featuring the Bangladesh Tigers, and major international Test and ODI fixtures. Markets update in real time as the match unfolds.

BPL bets on cvk4 are governed by standard cricket betting rules. A match must reach a minimum number of overs (typically five per side for T20) for bets to stand; rain-interrupted or abandoned matches may be voided depending on the specific market. Bets placed before the toss are confirmed once the toss result is known. Always review the full market rules in your bet slip before confirming.

cvk4 exclusively partners with certified game providers such as Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi — all of which use independently audited Random Number Generators (RNGs). The RTP (Return to Player) percentage for each slot and casino game is published in the game's information panel. cvk4 does not modify game outcomes in any way.

Yes — cvk4 is fully optimised for mobile browsers on both Android and iOS devices. You can access the complete game library, deposit and withdraw funds, and place live cricket bets directly from your smartphone without downloading any additional app. The mobile interface adapts automatically to your screen size for a smooth playing experience.

RTP varies by slot title and provider. Most Pragmatic Play and NetEnt slots on cvk4 carry an RTP between 94% and 97%. For example, popular titles like Crazy 777 and Wild Bandito display their exact RTP in the game information panel before you start playing. Higher RTP means a lower house edge over the long run, though individual session outcomes remain random.

Bonuses & Promotions

Learn how cvk4 welcome bonuses work, what wagering requirements mean, how free spins caps apply, and how the loyalty programme rewards regular players.

cvk4 offers a welcome bonus to new players on their first deposit. The current offer, bonus percentage, and maximum bonus amount are displayed on the promotions page after you log in. Bonus terms — including minimum deposit, wagering requirements, eligible games, and expiry period — are clearly outlined for each promotion so you know exactly what to expect before opting in.

A wagering requirement is the total amount you must bet before bonus funds or bonus winnings can be converted to withdrawable cash. For example, a ৳1,000 bonus with a 20x wagering requirement means you need to place ৳20,000 in total bets before the bonus clears. On cvk4, wagering progress is tracked in real time in your account's bonus section.

Free spins promotions on cvk4 may carry a maximum win cap — the specific cap is stated in each promotion's terms and conditions. Winnings above the cap are not credited. Always read the individual promotion rules before using free spins so you are fully aware of any limits that apply to your potential winnings.

Yes — cvk4 rewards regular players through a tiered loyalty programme. As you wager, you accumulate points that move you up through loyalty tiers. Higher tiers unlock benefits including enhanced withdrawal limits, exclusive bonus offers, faster withdrawal processing, and access to a dedicated account manager. Full programme details are available in the promotions section after logging in.
