1. Acceptance of Terms

By registering an account, logging in, or otherwise using the 399b platform, you acknowledge that you have read these Terms & Conditions in their entirety and agree to be legally bound by them. These terms constitute the entire agreement between you and 399b with respect to your use of the platform and supersede all prior communications or understandings on the same subject.

These Terms & Conditions apply alongside any other rules, guidelines, or policies that 399b may publish from time to time, including game-specific rules, promotional terms, and the Privacy Policy. In the event of a conflict, these Terms & Conditions shall take precedence unless otherwise stated.

2. Eligibility Requirements

To register and use the 399b platform, you must satisfy all of the following eligibility requirements at the time of registration and on a continuing basis throughout your use of the platform:

  • You must be at least 21 years of age. 399b strictly prohibits access by minors. Age verification may be requested at any time.
  • You must be a natural person (not a corporation, partnership, or other legal entity) capable of entering into legally binding contracts.
  • You must not be accessing the platform from a jurisdiction where online gambling is expressly prohibited by applicable law.
  • You must not have been previously excluded, suspended, or permanently banned from the 399b platform or any related service.

Age Policy: 399b operates a strict 21+ policy across all products and markets. If we have reasonable grounds to believe a user is under 21 years of age, we will immediately suspend the account pending identity verification. Any winnings accumulated during this period may be withheld.

3. Account Registration and Security

Each individual may hold only one account on the 399b platform. Creating multiple accounts — whether under different names, email addresses, phone numbers, or payment methods — is strictly prohibited and will result in immediate account closure and forfeiture of funds. When registering, you agree to provide accurate, current, and complete information and to keep that information up to date throughout your use of the platform.

Your Responsibilities

  • Keep your username and password strictly confidential. Do not share your login credentials with any other person.
  • Notify 399b support immediately if you suspect unauthorized access to your account or that your password has been compromised.
  • Ensure that the personal details registered to your account (name, date of birth, payment details) are truthful and match your official identification documents.
  • You are solely responsible for all activity conducted under your account, including any bets, deposits, and withdrawals made by anyone using your credentials.

KYC Verification

399b may require you to complete Know Your Customer (KYC) verification before processing withdrawals or at any point during your use of the platform. This may include providing a copy of a government-issued photo ID, proof of address, and proof of payment method ownership. Failure to provide adequate documentation within the requested timeframe may result in account suspension.


4. Deposits and Withdrawals

399b supports a range of trusted payment methods widely used across Bangladesh to ensure seamless fund management for all players. All monetary values on the platform are denominated in Bangladeshi Taka (৳ / BDT).

Deposit Conditions

  • Minimum deposit amount is ৳200. Deposits are generally processed instantly, subject to the payment provider's processing times.
  • Only deposit funds that belong to you. 399b does not accept deposits from third-party sources, including funds from other individuals or companies.
  • 399b reserves the right to request verification of the source of funds at any point. Deposits made using fraudulent payment credentials will result in account termination and possible legal action.

Withdrawal Conditions

  • Minimum withdrawal amount is ৳500. Withdrawals are typically processed within 1 to 3 business days, subject to KYC status and payment provider processing.
  • Withdrawals will only be sent to the same payment account used for the original deposit (bKash, Nagad, Rocket, Upay, or bank account as applicable). This is a standard anti-money-laundering control.
  • Any active wagering requirements attached to a bonus must be fully satisfied before a withdrawal can be processed. Attempting to withdraw funds before meeting rollover conditions may result in bonus cancellation.

5. Bonuses and Promotional Offers

399b periodically offers bonuses, free spins, cashback promotions, and other incentives to both new and existing players. All bonuses are subject to specific terms that govern how they may be used and when any associated winnings can be withdrawn.

  • Welcome bonus offers are available to new players who complete registration and make a qualifying first deposit. The minimum qualifying deposit, bonus percentage, and wagering requirements will be published on the relevant promotion page.
  • Standard wagering requirement for most 399b bonuses is 20x the bonus amount. Unless stated otherwise, bonuses must be wagered before any withdrawal can be made from the bonus balance.
  • Bonuses are personal and cannot be transferred, sold, or shared. Only one bonus may be active per account at any given time unless a specific promotion states otherwise.
  • 399b reserves the right to modify, suspend, or cancel any promotion at any time without prior notice. Players found to be abusing bonus offers — including through the use of multiple accounts or coordinated wagering — will have their bonuses voided and may face account termination.

Free spins issued as part of a promotion are subject to the same wagering requirements unless the promotion explicitly states otherwise. Winnings from free spins will be credited as bonus funds, not real-money funds, until the applicable rollover condition is met.

Bonus Abuse Warning: 399b employs advanced detection systems to identify patterns of systematic bonus exploitation. Accounts found to be engaged in matched betting, arbitrage, or other strategies designed primarily to extract bonus value without genuine gameplay may be closed and all associated funds forfeited.


6. Responsible Gaming

399b is committed to promoting responsible gaming practices across its platform. We believe gambling should be an enjoyable form of entertainment — not a financial obligation or a source of distress. We encourage all players to set personal limits and to seek help if their gambling habits begin to cause concern.

  • Deposit limits, session time limits, and self-exclusion tools are available to all registered players. Contact our support team to activate these features.
  • 399b will not extend credit to players. Never gamble with money you cannot afford to lose. Do not use gambling as a means to recover previous financial losses.
  • For more information and support resources, please visit our Responsible Gaming page. If you are worried about your gambling, you can request self-exclusion by contacting our support team at [email protected].

7. Prohibited Activities

The following activities are strictly prohibited on the 399b platform and will result in immediate account suspension, forfeiture of funds, and may be reported to the relevant authorities:

  • Using automated bots, scripts, or artificial intelligence tools to interact with games, claim bonuses, or manipulate outcomes.
  • Engaging in or facilitating money laundering through the platform, including layering funds through multiple accounts or payment methods to obscure the origin of funds.
  • Attempting to exploit software bugs, glitches, or technical errors to gain an unfair advantage. Any winnings obtained through such exploitation will be voided.
  • Providing false identity information, submitting fraudulent documents, or impersonating another person during KYC verification or any other account process.
  • Using the platform while self-excluded, or circumventing self-exclusion measures by registering under a different name or using another person's account credentials.

8. Intellectual Property

All content on the 399b platform — including but not limited to logos, trademarks, software, game assets, graphics, text, and promotional materials — is the exclusive property of 399b or its licensed content providers and is protected by applicable intellectual property laws. You may not reproduce, distribute, modify, create derivative works from, publicly display, or otherwise exploit any content from the 399b platform without prior written permission.

Game software provided through the 399b platform by third-party studios such as Pragmatic Play, Evolution Gaming, Spribe, NetEnt, and Microgaming remains the intellectual property of those respective studios. 399b holds valid licences to operate these games on its platform; users are granted only a limited, non-transferable licence to use the platform for personal, non-commercial entertainment purposes.

9. Limitation of Liability

To the fullest extent permitted by applicable law, 399b shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising from your use of the platform. Specifically, but without limitation, 399b is not liable for:

  • Any loss of funds resulting from unauthorized access to your account where you have failed to keep your login credentials secure.
  • Interruptions to service arising from scheduled maintenance, technical faults, third-party service failures, force majeure events, or factors beyond 399b's reasonable control.
  • Any financial losses, gambling debts, or negative consequences resulting from your use of the platform, including losses incurred due to a technical error that was subsequently corrected.

10. Account Suspension and Termination

399b reserves the right to suspend, restrict, or permanently close any account at its sole discretion. Circumstances that may lead to account action include, but are not limited to:

  • Breach of any provision within these Terms & Conditions, including but not limited to prohibited activities, bonus abuse, or the use of multiple accounts.
  • Suspicion of fraudulent activity, collusion, match-fixing, or other actions that undermine the integrity of the platform or its games.
  • Failure to provide adequate identity or payment verification documentation within the timeframe requested by 399b's compliance team.

Fund Return on Closure: Where an account is closed for reasons other than fraud, abuse, or breach of these terms, any remaining real-money balance (excluding bonus funds) will be returned to the player via the payment method on file, subject to standard KYC clearance. Accounts closed due to a confirmed breach will have all balances forfeited.


11. Dispute Resolution

In the event of a dispute regarding a transaction, bet outcome, or any other aspect of the 399b service, you should first contact our support team at [email protected] with a clear description of the issue, your account details, and any supporting evidence. 399b aims to acknowledge all complaints within 48 hours and to resolve them within 14 business days where possible.

In all disputes regarding game outcomes, the game server log maintained by 399b or its certified game provider shall be the definitive record. In the event of a discrepancy between the game display on your device and the server log, the server log shall prevail. 399b's decision on all matters relating to game fairness, bonus eligibility, and account conduct shall be final, subject only to the dispute process described above.

12. Amendments to These Terms

399b may revise these Terms & Conditions at any time. When material changes are made, we will provide reasonable notice to registered users via email or a prominent notice on the platform. The updated terms will display the revised effective date at the top of the page. Your continued use of the 399b platform after the effective date of any revision constitutes your acceptance of the updated terms.

If you do not agree with a revised version of the Terms & Conditions, you must stop using the platform and may request account closure by contacting our support team. It is your responsibility to review these terms periodically to remain informed of any changes that may affect your use of the platform.
