21tk Frequently Asked Questions

Creating a 21tk account takes under two minutes. Visit 21tk.org, tap the sign-up option, enter your Bangladesh mobile number, choose a secure password, and confirm you are 21 or older. You will receive a one-time password (OTP) to verify your number. Once verified, your account is active and you can make your first deposit via bKash, Nagad, or Rocket.

The minimum age to register and play on 21tk is 21 years. This is a strict requirement that applies to all players accessing the platform from Bangladesh or any other location. Age verification may be requested before your first withdrawal. Any account found to be held by a person under 21 will be closed and all balances forfeited.

21tk may request a government-issued identity document for KYC verification before processing your first withdrawal or during a compliance review. Accepted documents include a Bangladesh National Identity Card (NID) or passport. Send a clear photo or scanned copy to [email protected]. Verified accounts benefit from faster withdrawal processing.

If you have forgotten your 21tk password, email [email protected] with your registered mobile number and request a password reset. Our team will verify your identity and issue a reset link or OTP to your registered number within one hour. For your security, 21tk will never ask you to share your password via email or any other channel.

No — each player is permitted to hold only one 21tk account. Registering duplicate accounts is a breach of the Terms and Conditions and may result in all accounts being suspended along with any balances. If you suspect a duplicate account was created accidentally under your mobile number, contact [email protected] immediately to have the issue resolved.

bKash deposits on 21tk are credited almost instantly — usually within 30 seconds to 2 minutes of a confirmed bKash transaction. If your balance has not updated after 10 minutes, contact [email protected] with your bKash transaction reference number and our team will investigate and manually credit your account if required.

The minimum deposit on 21tk is ৳200 BDT. This limit applies to all supported payment methods including bKash, Nagad, Rocket, and Upay. There is no specified maximum deposit, though large deposits may trigger an additional identity verification step in line with our compliance procedures.

The minimum withdrawal amount on 21tk is ৳500 BDT. Withdrawals are sent to the same payment method used for your most recent deposit — for example, a deposit via Nagad means your withdrawal goes back to your Nagad wallet. Processing typically takes 1 to 4 hours for bKash and Nagad, and up to 24 hours for bank transfers to Dutch-Bangla, BRAC, or other Bangladeshi banks.

21tk does not charge any platform-side fees on deposits or withdrawals. However, your payment provider — such as bKash, Nagad, or Rocket — may apply their own transaction fees in line with their standard schedule. We recommend checking your provider's current fee structure if you have concerns about third-party charges before transferring funds.

All games on 21tk use certified random number generator (RNG) technology provided by established studios such as Pragmatic Play, Evolution Gaming, and Ezugi. RNG certification means every spin, deal, or outcome is statistically independent and cannot be influenced. Return-to-player (RTP) percentages for each game are typically shown in the game's information panel.

21tk's live casino streams real-dealer games in real time from professional studios.

21tk offers a welcome bonus to newly registered players who complete their first qualifying deposit. Bonus details — including the match percentage, maximum bonus amount in BDT, and eligible games — are published on the promotions section of the platform and updated regularly. Always read the full T&C before claiming so you understand the wagering requirements and expiry date.

A wagering requirement is the number of times you must bet the bonus amount before bonus-derived winnings become withdrawable. For example, a ৳1,000 bonus with a 20x wagering requirement means you need to place ৳20,000 in total bets before you can withdraw. Not all games contribute equally to clearing the rollover — check the specific promotion terms for contribution percentages.

Yes — every 21tk bonus has an expiry window within which the wagering requirement must be completed. The validity period (commonly 7 to 30 days) is stated in the terms of each individual promotion. If the bonus expires before the rollover is met, the bonus and any winnings from it are removed from your account. Check each promotion's T&C carefully before accepting.

Check the promotions section before each major tournament begins.

21tk uses SSL encryption to protect all data transmitted between your device and our servers, and player funds are held separately from operational funds.
