b399 Terms & Conditions — Your Complete User Agreement
These Terms & Conditions govern your use of the b399 platform. By registering an account or placing any bet on b399, you confirm that you have read, understood, and agreed to all terms set out in this document. Please read carefully before proceeding.
Age Restriction — 18+ Only
b399 strictly prohibits access by individuals under 18 years of age. All accounts are subject to mandatory age and identity verification. Any account found to be registered by a person under 18 will be immediately suspended and all funds frozen pending investigation.
One Account Per Person
Each player may hold exactly one registered account on b399. Operating multiple accounts — whether under the same or different identities — constitutes a material breach of these Terms and will result in immediate suspension of all associated accounts and forfeiture of any pending withdrawals.
Fair Play Obligation
All players on b399 are required to engage with all games and betting markets in good faith. The use of automated betting software, bots, exploits, or any system designed to gain unfair advantage over the house or other players is strictly prohibited and will result in account termination.
Account Security Responsibility
You are solely responsible for maintaining the confidentiality of your b399 account credentials. b399 will never ask for your password via email, chat, or phone. Any activity conducted through your account — regardless of whether you personally performed it — is your responsibility unless you have notified b399 of unauthorised access.
Withdrawals to Verified Methods Only
All withdrawals from b399 are processed exclusively to payment methods that have been verified in the player's name. Third-party withdrawals — where the receiving account belongs to a different individual — are strictly forbidden and will trigger an immediate compliance review.
Terms Subject to Change
b399 reserves the right to modify these Terms & Conditions at any time. Material changes will be communicated to registered players via the email address on file at least 7 days before the change takes effect. Continued use of the b399 platform after the effective date constitutes acceptance of the revised Terms.
General Terms & Acceptance
These Terms & Conditions ("Terms") constitute a legally binding agreement between you ("the Player", "User", "you") and b399 ("b399", "the Platform", "we", "us", "our") governing all use of the b399 website, mobile application, and any related services accessible through https://b399.app or its associated domains and subdomains. By creating an account, accessing the platform, placing a bet, depositing funds, or using any feature of b399, you confirm that you have read these Terms in full, understood their contents, and agree to be bound by them without reservation.
These Terms apply to all products and services offered through b399, including but not limited to: sports betting (cricket, football, kabaddi, hockey, tennis, and all other available markets), live casino games (Baccarat, Roulette, Blackjack, Teen Patti, Andar Bahar, and all Evolution Gaming, Pragmatic Play Live, and Ezugi-supplied tables), slots and RNG games (all titles from Pragmatic Play, NetEnt, Microgaming, and partner studios), crash games (including Aviator by Spribe and all other multiplier-format titles), promotional bonuses, and any future products or features added to the b399 platform.
These Terms are supplemented by the following additional policy documents, each of which forms part of the overall agreement between you and b399:
- Privacy Policy — governing how b399 collects, stores, processes, and shares your personal data
- Responsible Gaming Policy — setting out b399's commitments and the player tools available for managing gambling behaviour
- Bonus & Promotions Terms — containing the specific wagering requirements, eligibility conditions, and expiry rules applicable to each individual b399 promotion
- Game-Specific Rules — applicable to individual game formats, accessible via the information panel within each game on the b399 platform
In the event of any conflict or inconsistency between these general Terms and any game-specific or promotion-specific terms, the more specific document shall prevail in relation to that specific game or promotion, and these general Terms shall govern all other matters.
Governing Language: These Terms are written in English and the English version shall be the authoritative version for all interpretation and dispute resolution purposes. Any translations provided for convenience do not alter the meaning of the English original.

Eligibility & Age Restriction
Access to b399 and the ability to register an account, deposit funds, or place bets is restricted to individuals who meet all of the following eligibility criteria at the time of registration and at all times during which the account remains active:
- Age: You must be at least 18 years of age. This requirement is absolute and non-negotiable. b399 does not offer any exceptions, trial periods, or demonstration access to individuals under 18, regardless of jurisdiction or parental consent status.
- Legal Capacity: You must have the full legal capacity to enter into a binding contract under the laws of your jurisdiction. If you are subject to any legal guardianship order or have been declared legally incapacitated, you are not permitted to register or use b399.
- Not a Prohibited Person: You must not be resident in or a national of any jurisdiction where the use of online gambling platforms is prohibited by applicable law. It is your sole responsibility to verify that using b399 is lawful in your jurisdiction before registering.
- Not Self-Excluded: You must not have an active self-exclusion in place on b399 or through any recognised third-party self-exclusion scheme. Attempting to circumvent a self-exclusion by registering a new account is a serious breach of these Terms.
- Not a b399 Employee or Associate: Current employees, contractors, consultants, and immediate family members of b399 staff are not permitted to hold player accounts or participate in any promotional programme on the platform.
Age Verification Process
b399 operates a mandatory Know Your Customer (KYC) verification process for all accounts. Upon registration, or at any point prior to processing a withdrawal request, b399 may require you to submit one or more of the following documents to verify your age and identity:
- National Identity Card (NID) — Bangladesh National ID
- Valid passport (any nationality)
- Driver's licence (Bangladesh or international)
- Birth certificate (for age verification if other documents are unavailable)
For address verification, b399 may additionally request a recent utility bill, bank statement, or official government correspondence dated within the last three months showing your name and residential address in Bangladesh.
Until KYC verification is completed to b399's satisfaction, withdrawal requests may be held pending. b399 reserves the right to suspend an account and hold funds if verification documents are not submitted within 30 days of the first withdrawal request, or if the documents provided are found to be fraudulent, altered, or inconsistent with the registration information provided.
18+ Strictly Enforced: b399 uses automated age-screening tools at registration and manual document review at withdrawal. Any account found to belong to a person under 18 will be permanently suspended without appeal.
| Requirement | Status |
|---|---|
| Minimum Age | 18 years |
| ID Verification | Mandatory |
| Address Proof | Required for withdrawals |
| One Account Limit | Strictly enforced |
| Self-Excluded Players | Access denied |
Account Registration & Verification
To access the full range of b399 services — including deposits, betting, live casino, and withdrawals — you must register a personal account. The registration process requires you to provide accurate, current, and complete information including your full legal name, date of birth, residential address in Bangladesh, a valid mobile number (for OTP verification), and a unique email address not previously associated with any other b399 account.
Accuracy of Registration Information: You warrant that all information provided during registration is true, accurate, current, and complete. Providing false, misleading, or incomplete registration information — including using a false name, date of birth, or address — constitutes immediate grounds for account suspension, forfeiture of balance, and potential reporting to relevant authorities where applicable law requires it.
Account Security: You are solely responsible for all activity conducted through your b399 account. You must select a strong, unique password and must not share your login credentials with any third party. If you suspect that your account has been accessed without your authorisation, you must notify b399 immediately at [email protected] so that the account can be secured. b399 cannot be held liable for losses resulting from unauthorised access where the player has failed to maintain adequate account security.
Account Name Consistency: The name on your b399 account must exactly match the name on the payment methods you use for deposits and withdrawals. Discrepancies between the account name and the registered payment method name will delay or block withdrawal processing until the inconsistency is resolved through the KYC process.
Two-Factor Authentication
b399 offers OTP-based two-factor authentication (2FA) via your registered mobile number. Players are strongly encouraged to enable 2FA to add an additional layer of security to their account. In the event of a dispute relating to account access, b399 may require evidence that 2FA was in place before investigating claims of unauthorised activity.
KYC Documents Accepted
b399 accepts the following for identity verification:
- Bangladesh National ID (NID)
- Valid Passport
- Driver's Licence
- Birth Certificate
- Recent utility bill or bank statement (address proof)
Deposits, Withdrawals & Payments
All financial transactions on b399 are conducted in Bangladeshi Taka (BDT). b399 does not charge currency conversion fees on BDT transactions. The following payment methods are accepted for both deposits and withdrawals, subject to the individual minimum and maximum limits published in the b399 cashier section:
bKash
Instant processing for verified accounts
Nagad
Instant processing for verified accounts
Rocket

Deposit Rules
- The minimum deposit on b399 is ৳200 via bKash or Nagad. Minimum amounts for other payment methods are displayed in the cashier.
- All deposits must originate from a payment method registered in your own name. Deposits from third-party accounts — accounts belonging to other individuals — will be returned and may trigger a compliance review.
- b399 reserves the right to request proof of the depositing payment method (e.g., a screenshot of the bKash or Nagad account showing the registered name and number) as part of the KYC process.
- Deposits are credited to your b399 wallet balance upon confirmation from the payment provider. b399 is not responsible for delays caused by the payment provider's own processing systems.
Withdrawal Rules
- Withdrawal requests are processed during b399 operational hours (Bangladesh Standard Time, UTC+6). The target processing time for verified accounts is under 60 minutes for bKash and Nagad withdrawals, subject to bank and MFS provider processing times.
- KYC verification must be fully completed before any withdrawal is approved. Accounts with incomplete or pending verification will have withdrawal requests held until the verification process is finalised.
- Withdrawals are processed exclusively to the same payment method used for the most recent qualifying deposit, or to a verified payment method in the player's name on file with b399.
- Any active bonus balance subject to wagering requirements must be fully wagered before a withdrawal of the associated real-money balance can be processed. Attempting to withdraw while a bonus wagering requirement is incomplete will result in the bonus and associated bonus winnings being forfeited prior to withdrawal approval.
- b399 reserves the right to conduct enhanced due diligence on withdrawal requests exceeding ৳50,000 in a single transaction, which may extend processing times by up to 3 business days.
Anti-Money Laundering (AML): b399 operates a strict anti-money laundering policy in line with international best practices. Any deposit or withdrawal pattern that suggests layering, placement, or integration of illicit funds will be investigated and reported to the relevant authorities. b399 reserves the right to freeze account balances and withhold withdrawals during AML investigations without prior notice.
Bonuses & Promotions
b399 offers a range of bonuses and promotional offers to both new and existing players. All bonuses are subject to the specific terms published alongside each individual promotion in the b399 Promotions section. The following general rules apply to all b399 bonuses unless the specific promotion terms state otherwise:
- Welcome Bonus: New players registering their first b399 account are eligible for the b399 Welcome Bonus of 100% on the first deposit up to ৳20,000. The Welcome Bonus is available once per player, per household, per device, and per IP address. Any attempt to claim the Welcome Bonus multiple times through duplicate accounts will result in forfeiture of the bonus and potential account suspension.
- Wagering Requirements: All bonuses are subject to a wagering requirement — the number of times the bonus amount (or bonus plus deposit amount, as specified per promotion) must be wagered before a withdrawal can be requested. Specific wagering multiples, eligible games, and contribution rates are displayed on each promotion detail page.
- Game Contribution Rates: Not all games contribute equally to meeting wagering requirements. Typically, slots contribute 100%, while live casino games, crash games, and sports bets may contribute a lower percentage. Exact contribution rates are published on the individual promotion page.
- Bonus Expiry: All b399 bonuses carry an expiry period, typically 7 to 30 days from the date of credit, as specified per promotion. If wagering requirements are not met within the bonus expiry period, the bonus and any associated bonus winnings will be automatically forfeited.
- Bonus Abuse: b399 monitors all bonus activity for patterns consistent with bonus abuse, including but not limited to: systematic low-risk wagering designed to meet requirements without genuine play, coordinated multi-account wagering, and exploitation of offer mechanics not intended by b399. Any account found to be engaged in bonus abuse will have bonuses forfeited and the account reviewed for suspension.
- Seasonal Promotions: b399 runs Eid, Pohela Boishakh, BPL season, and other calendar-based promotions periodically. These promotions are available for a limited time only and are subject to their own specific terms. b399 is not obligated to repeat any seasonal promotion in future periods.
b399 reserves the right to modify, suspend, or withdraw any bonus or promotional offer at any time, with or without prior notice, where continued operation of the promotion would constitute a risk to the platform or its players, or where a technical error has resulted in incorrect bonus crediting.
| Bonus Parameter | Standard Rule |
|---|---|
| Welcome Bonus | 100% up to ৳20,000 |
| Wagering | Per promotion page |
| Expiry | 7–30 days |
| Per Player | One welcome bonus |
| Slot Contribution | 100% (standard) |
| Live Casino | Reduced % (see promo) |
Betting & Gaming Rules
All bets and game rounds on b399 are subject to the specific rules applicable to the event, market, or game title in question, as published within the b399 platform. The following general rules apply across all product verticals:
Sports Betting
- All cricket bets — including BPL, IPL, Bangladesh Tigers international fixtures, T20 World Cup, and ICC tournaments — are settled in accordance with the official result published by the governing body of the relevant competition. b399 does not rely on broadcast commentary or unofficial sources for settlement purposes.
- In-play bets are accepted at b399's absolute discretion. b399 reserves the right to suspend in-play markets at any time without notice, particularly where there is a concern about data integrity, connectivity, or unusual betting patterns.
- Bets placed after the official start of an event — whether due to a technical delay or connectivity issue on the player's side — may be voided at b399's discretion.
- b399 reserves the right to limit, restrict, or refuse any bet from any player at any time, without providing a reason. This applies particularly where b399 identifies patterns consistent with match-fixing information, insider knowledge, or coordinated syndicate activity.
- Maximum winnings from a single bet or accumulator are capped at ৳5,000,000 per market per settlement event, unless explicitly stated otherwise in a specific market or promotional context.
Casino & Slots
- All casino game outcomes are determined by the RNG (Random Number Generator) systems of the game provider — Pragmatic Play, NetEnt, Microgaming, Evolution Gaming, Ezugi, or Spribe — and not by b399. b399 does not control, influence, or interfere with game outcomes.
- In the event of a game malfunction, disconnection, or technical error during a casino game round, b399's liability is limited to returning the bet stake for the affected round. b399 is not responsible for losses arising from connection failures on the player's device or network.
- Jackpot wins and large single-round wins above ৳1,000,000 may be subject to verification before payment, which may take up to 5 business days.
Dispute Resolution: Any dispute regarding bet settlement must be raised with b399 support at [email protected] within 30 days of the relevant event or game round settling. Disputes raised after this period will not be considered. b399's decision on all settlement disputes, made after review of the relevant data and provider records, is final and binding.
User Obligations & Prohibited Conduct
As a registered player on b399, you agree to use the platform lawfully, ethically, and in accordance with these Terms at all times. The following conduct is expressly prohibited and will result in account suspension, forfeiture of funds, and potential legal action where applicable:
- Multiple Accounts: Creating, operating, or benefiting from more than one b399 account per person, household, device, or IP address.
- Fraudulent Activity: Providing false identity documents, using stolen payment methods, initiating fraudulent chargebacks, or engaging in any form of financial fraud against b399 or other players.
- Automated Betting: Using bots, scripts, macros, artificial intelligence tools, or any form of automated system to place bets, exploit game mechanics, or circumvent platform security measures.
- Collusion: Coordinating with other players to manipulate outcomes in poker, live casino games, or any other multiplayer format available on b399.
- Insider Betting: Placing bets using material non-public information about the outcome of a sporting event, including match-fixing information or information obtained from individuals directly involved in the event.
- Exploiting Errors: Deliberately exploiting software bugs, pricing errors, or system malfunctions to generate artificial winnings. Any winnings derived from an obvious error will be voided.
- Unauthorised Access: Attempting to access b399 systems, servers, databases, or other players' accounts through any means not authorised by b399.
- Misuse of Support: Submitting false claims to b399 support, including false reports of unauthorised access, incorrect game results, or fraudulent payment disputes.
b399 employs automated monitoring tools and a dedicated compliance team to identify and investigate suspected prohibited conduct. Where prohibited conduct is confirmed, b399 will take all available remedial action including account termination, balance forfeiture, and cooperation with law enforcement authorities in Bangladesh and internationally.
Account Suspension & Closure
b399 reserves the right to suspend, restrict, or permanently close any player account at any time, with or without prior notice, where b399 has reasonable grounds to believe that any of the following circumstances apply:
- The account holder is under 18 years of age or has provided false age documentation
- A material breach of any clause of these Terms & Conditions has occurred
- The account is subject to a fraud investigation, AML review, or law enforcement inquiry
- The account has been involved in prohibited conduct as defined in Section 7
- The account holder has requested a self-exclusion through the b399 responsible gaming tools
- b399 is required to close the account by applicable law, regulation, or court order
Player-Initiated Closure
You may request the closure of your b399 account at any time by contacting [email protected] with a clear written request. Before closing an account, b399 will process any pending withdrawal of your verified real-money balance to your registered payment method. Bonus balances that have not met their wagering requirements will be forfeited upon account closure.
Dormant Accounts
An account is considered dormant if no login activity has been recorded for a continuous period of 12 months. b399 reserves the right to apply a monthly dormancy administration fee of ৳200 to dormant accounts with a remaining balance, deducted from the balance until the balance reaches zero or the player re-activates the account by logging in. Players will be notified by email before dormancy fees begin to apply.
Data Retention After Closure: In accordance with b399's Privacy Policy and applicable data protection obligations, transaction records, account history, and identity verification documents may be retained for up to 5 years following account closure. This retention is required to meet anti-money laundering record-keeping obligations.
Self-Exclusion
If you need to take a break from gambling, b399's responsible gaming tools allow you to self-exclude for 6 months, 1 year, or permanently — directly from your account dashboard, without contacting support.
Contact for Account Issues
For all account closure, suspension, or dispute queries, write to b399 at [email protected]. All requests are handled during Bangladesh Standard Time (UTC+6) business hours.
