399bet Terms and Conditions

Please read all the terms below carefully before opening an account on this platform. By using the platform, you are considered to have agreed to these terms.

Last Updated: July 2025

This document sets out the binding terms and conditions governing the relationship between the 399bet platform and its users. By accessing the platform, creating an account, or using any service, the user is considered to have fully read, understood and accepted all of these terms.

These terms are written in English and apply to users in Bangladesh. In the event of any interpretive conflict, this English version shall be considered final. 399bet reserves the right to change these terms at any time — continued use of the platform after any change constitutes acceptance of the updated terms.

For matters not explicitly addressed in this document, generally accepted standard practices will apply.

To open an account on 399bet, users must meet the following requirements:

  • You must be at least 21 years of age. Use of this platform by minors is strictly prohibited.
  • Each individual may open only one account. If multiple accounts are found, all of them may be suspended.
  • All information provided at registration must be truthful, accurate and up to date.
  • Users must register under their own name; opening an account on behalf of someone else or under a false identity is prohibited.
  • Accessing the service from areas where online gaming is legally prohibited is entirely at the user's own responsibility.

399bet may request necessary documents for identity verification at registration. Withdrawal facilities may be limited until the verification process is complete.

Each user is solely responsible for the security of their account. Login credentials — username and password — must always be kept confidential and must not be shared with any third party.

A strong password is required, combining uppercase and lowercase letters, numbers and special characters. It is recommended to change your password regularly and not to use the same password on any other site.

If you suspect unauthorised access to your account, contact the 399bet support team immediately. 399bet will not be held responsible for any financial loss resulting from the user's own negligence.

For withdrawals above a certain amount, or whenever 399bet deems it necessary, users may be required to submit a copy of their national ID or passport and address verification documents. Certain account functions may be suspended until this process is complete.

All financial transactions on 399bet are conducted entirely by digital methods. bKash, Nagad, Rocket, Upay and bank transfer are currently available for deposits and withdrawals. Bank transfers are supported with major commercial banks including Dutch-Bangla Bank, BRAC Bank and Islami Bank.

  • Minimum deposit: ৳500 (per method).
  • Minimum withdrawal: ৳500.

Withdrawal requests are generally processed within 30 minutes to 3 hours of receipt. However, processing may take longer during verification or in unusual circumstances.

Users must ensure that deposited funds come from a legitimate source. In the case of suspicious transactions, 399bet reserves the right to block any transaction or suspend the account.

If an incorrect credit occurs due to a technical error, 399bet reserves the right to reclaim that amount. The user is obliged to return the funds even if they have already been spent.

399bet offers various types of bonuses and promotions. Each offer has its own terms and conditions that must be followed.

New members will receive a 100% bonus on their first deposit, up to ৳5,000. To receive this bonus, the bonus amount must be wagered 10 times. For example: a ৳1,000 deposit receives a ৳1,000 bonus, giving a balance of ৳2,000, and to withdraw the bonus, bets totalling ৳1,000 × 10 = ৳10,000 must be placed.


  • Bonus funds cannot be withdrawn directly — they may only be withdrawn after the wagering requirement has been met.
  • Another bonus cannot be activated while one bonus is already active.
  • 399bet reserves the right to cancel any bonus if fraud is suspected.
  • Transferring bonus funds to a third party is strictly prohibited.
  • Promotional offer terms are subject to change; visit the relevant promotion page for up-to-date information.

399bet offers various types of games including slots, live casino, sports betting, fishing games and bingo. Each game category has its own rules, which are provided within the game.

  • A confirmed bet generally cannot be changed or cancelled.
  • 399bet reserves the right to cancel bets accepted in error due to a technical fault.
  • In sports betting, if a match or event is cancelled, the bet is generally refunded.
  • Bets accepted before an odds change will be settled at the previous odds.

All games are operated through trusted software providers — such as Pragmatic Play, PG Soft, JILI, Evolution and Spribe. Game outcomes are determined by a Random Number Generator (RNG) and there is no possibility of any manipulation.

Engaging in any of the following activities may result in permanent account closure and forfeiture of deposited funds:

  • Operating an account using a false or another person's identity.
  • Knowingly exploiting any system vulnerability or bug to gain an unfair advantage.
  • Using bots, automated software or any fraudulent technology.
  • Opening multiple accounts to claim bonuses repeatedly.
  • Using the platform for money laundering or illegal transfer of funds.
  • Harassing other users or damaging the reputation of the platform.
  • Attempting fraud through chargebacks or payment disputes.

399bet is committed to providing a smooth and quality service at all times. However, the limits of our liability are clarified below:

  • 399bet is not responsible for losses caused by internet disconnection, power outages or technical faults on the part of third parties.
  • If account information is leaked as a result of the user's own negligence, 399bet will not be held responsible.
  • Game outcomes are entirely random and not predetermined — no specific win is guaranteed.
  • There is no obligation to refund any bet amount lost due to a temporary service interruption, however each case will be reviewed.

We always encourage responsible gaming. Visit our responsible gaming guidelines page to learn more, including options to set personal limits and take a voluntary break.

For full details on how your personal information is collected, stored and used, please see our Privacy Policy. It contains complete information on cookie use, sharing data with third parties and user rights.

399bet uses SSL encryption and other security technologies to keep users' financial and personal information secure. Payment information is never stored directly on our servers — it is processed through authorised payment gateways.

Collected information is used solely for account management, payment processing, fraud prevention and service improvement. If you are contacted for marketing purposes, you may request to opt out at any time.

A user may voluntarily request to close their account at any time. It is advisable to withdraw all valid balances before submitting the request.

399bet may suspend or close an account without prior notice in any of the following situations:

  • Violation of any provision of these terms.
  • Suspicion of fraudulent activity.
  • Failure to complete identity verification or provision of false information.
  • An order from a court or authority.
  • Long-term inactive account (generally more than 12 months).

If an account is closed for reasons other than a breach of rules, the valid balance may be withdrawn. In cases of rule violations, bonus-related balances may be forfeited.

399bet reserves the right to change, amend or add to any part of these terms at any time. For significant changes, an attempt will be made to notify users via their registered email or through the platform.

Continued use of the platform after any change means the user is automatically considered to have agreed to the new terms. It is therefore recommended to review this page regularly. You can also visit our Frequently Asked Questions (FAQ) page for answers to common questions.

If you have any questions or feedback about these terms, please contact the 399bet support team. Our support service is available seven days a week, 24 hours a day, in both Bengali and English.

  • Live Chat: Instant support is available via the chat icon in the bottom-right corner of any page on the platform.
  • Email: [email protected]
