Each player is permitted one 399b account only. Duplicate accounts are not allowed and will result in suspension. Your account is personal — it cannot be shared, transferred, or sold to another person under any circumstances.
You must be at least 18 years old to register and play on 399b. Age verification may be requested at any point. Accounts found to belong to players under 18 will be closed immediately and any balance will be handled in accordance with applicable policy.
All bonuses on 399b are subject to wagering requirements before they can be withdrawn. The specific requirement for each bonus is stated clearly in the promotion details. Attempting to withdraw bonus funds before meeting the requirement will result in the bonus being forfeited.
All transactions on 399b are processed in Bangladeshi Taka (BDT) via bKash, Nagad, or Rocket. Withdrawals are sent to the same payment method used for the most recent deposit. 399b does not charge fees on standard deposits or withdrawals.
You are responsible for keeping your 399b login credentials secure. 399b will never ask for your password via email, chat, or phone. Any activity that occurs on your account while you are logged in is your responsibility — report suspicious activity to support immediately.
399b reserves the right to suspend or close any account that is found to be in breach of these terms, involved in fraudulent activity, or operating in a way that is harmful to other players or the platform. Decisions are made fairly and can be appealed via the support team.
These Terms and Conditions ("Terms") constitute a legally binding agreement between you ("Player", "User", "you") and 399b ("399b", "we", "us", "the platform"). By accessing the 399b website, creating an account, making a deposit, or using any feature of the 399b platform, you confirm that you have read these Terms in full and agree to be bound by them.
If you do not agree with any part of these Terms, you must not use the 399b platform. Continued use of 399b after any update to these Terms constitutes acceptance of the revised version. 399b recommends that all players review these Terms periodically to stay informed of any changes.
These Terms apply to all players using 399b from Bangladesh. By registering, you confirm you are doing so voluntarily and in accordance with the laws applicable to you.
To register and use the 399b platform, you must meet all of the following eligibility requirements:
399b reserves the right to request proof of age and identity at any time. If a player is found to be under 18, their account will be closed immediately, all pending withdrawals will be cancelled, and any deposited funds will be returned to the original payment method after deducting any winnings generated during the period of underage use.
Each player may hold only one active account on 399b. Creating multiple accounts — whether under the same name, the same device, the same IP address, or the same payment method — is strictly prohibited and will result in all associated accounts being suspended.
When registering your 399b account, you agree to provide accurate, complete, and current information. This includes your full legal name, date of birth, mobile number, and any other information requested during the registration process. Providing false information is a breach of these Terms and may result in account closure and forfeiture of any balance.
You are responsible for maintaining the confidentiality of your 399b login credentials. Do not share your username or password with anyone. 399b will never contact you to ask for your password. If you believe your account has been accessed without your authorisation, contact 399b support immediately via live chat.
399b may require identity verification (KYC) before processing your first withdrawal. This is a standard security measure to protect all players on the platform.
399b accepts deposits in Bangladeshi Taka (BDT) via bKash, Nagad, and Rocket. All deposits are credited to your 399b account balance in BDT with no currency conversion and no platform-side deposit fees. Minimum deposit amounts and any applicable limits are displayed on the deposit page within your account.
Deposits must be made from a payment account that belongs to you. 399b does not accept deposits from third-party accounts. If a deposit is received from a payment account that does not match the name on your 399b account, the deposit may be reversed and the account suspended pending investigation.
Withdrawals from your 399b account are processed to your registered bKash, Nagad, or Rocket account in BDT. 399b aims to process all withdrawal requests within five minutes during normal operating hours. Processing times may be longer during periods of high demand or if additional verification is required.
Before your first withdrawal can be processed, 399b may require you to complete identity verification. This involves submitting a copy of a valid government-issued ID and confirming ownership of your registered payment method. This process is completed once and does not apply to subsequent withdrawals.
Withdrawals can only be made to accounts registered in your own name. Third-party withdrawals are not permitted under any circumstances.
399b offers a range of bonuses and promotions to both new and existing players. All bonuses are subject to the specific terms stated in the relevant promotion, including wagering requirements, minimum deposit thresholds, eligible games, and expiry dates. These promotion-specific terms form part of these overall Terms and Conditions.
Wagering requirements must be met in full before any bonus-derived winnings can be withdrawn. The wagering requirement for each bonus is clearly stated in the promotion details. If you attempt to withdraw before meeting the requirement, the bonus and any associated winnings will be forfeited.
All games available on 399b — including slots, fishing games, card games, and live casino tables — operate using certified random number generation (RNG) systems. Game outcomes are determined independently and cannot be influenced by 399b, by other players, or by any external party. 399b's RNG systems are subject to regular independent audits to confirm ongoing fairness.
Each game on 399b has its own set of rules, which are accessible from within the game interface. Players are responsible for understanding the rules of any game before placing real-money bets. 399b is not liable for losses resulting from a player's misunderstanding of game rules.
The following actions are strictly prohibited on the 399b platform. Engaging in any of these activities will result in immediate account suspension, forfeiture of balance, and may be reported to relevant authorities where applicable.
399b monitors all account activity continuously. Suspicious patterns are flagged automatically and reviewed by the security team. We take the integrity of the platform seriously for the benefit of all players.
399b reserves the right to suspend, restrict, or permanently close any account at its discretion, particularly where there is evidence or reasonable suspicion of a breach of these Terms. Where possible, 399b will notify the affected player and provide an opportunity to respond before a final decision is made.
If your account is suspended due to a suspected breach, any pending withdrawals may be placed on hold during the investigation period. If the investigation concludes that no breach occurred, the account will be reinstated and any held withdrawals processed promptly.
399b is committed to promoting responsible gaming across its entire player base. We provide a range of tools that allow players to manage their gaming activity, including deposit limits, session time reminders, cooling-off periods, and self-exclusion options. These tools are available to all players from within their account settings at any time.
If you feel that your gaming is becoming a problem, we strongly encourage you to use these tools or contact the 399b support team for assistance. Gaming on 399b should always be an enjoyable form of entertainment — not a source of financial stress or personal harm.
399b collects and processes personal data in accordance with its Privacy Policy. By registering on 399b, you consent to the collection and use of your personal information as described in that policy. 399b uses your data to operate your account, process transactions, verify your identity, and communicate with you about your account and relevant promotions.
399b does not sell your personal data to third parties. Data is shared only where necessary for the operation of the platform — for example, with payment processors to facilitate deposits and withdrawals — and only to the extent required for that purpose.
