399bid Terms & Conditions

Please read these Terms & Conditions carefully before registering or using the 399bid platform. By accessing any part of this website, you agree to be bound by the provisions set out below.

Last updated: 1 January 2026  |  Effective immediately upon registration

1. Introduction and Acceptance

Age Restriction: The Services are available exclusively to individuals who are 21 years of age or older. If you are under 21, you are strictly prohibited from registering an account, depositing funds, or participating in any game or betting activity on the 399bid platform.


2. Eligibility and Account Registration

You must meet all of the following conditions to open and maintain a 399bid account.

  • 2.1 You must be a natural person aged 21 years or older. Corporate entities, bots, and automated scripts are not permitted to register accounts.
  • 2.2 You must register using accurate, current, and complete personal information. Providing false, misleading, or incomplete information at the point of registration is a material breach of this Agreement and may result in immediate account suspension or permanent closure without refund of funds.
  • 2.3 Each individual is permitted to hold one (1) account only. Duplicate accounts ("multi-accounting") are strictly prohibited. 399bid reserves the right to merge, suspend, or permanently close duplicate accounts and to void any winnings or bonuses generated across such accounts.
  • 2.4 You are solely responsible for maintaining the confidentiality of your account credentials, including your username and password. You must notify 399bid immediately if you become aware of any unauthorised access to your account. 399bid shall not be liable for any losses resulting from your failure to safeguard your login details.
  • 2.5 399bid may, at its sole discretion, require you to submit identity verification documents (Know Your Customer, "KYC") before processing any withdrawal. Acceptable documents include government-issued national identity cards, passports, and utility bills issued within the past three months confirming your residential address.
  • 2.6 You confirm that you are not a resident of any jurisdiction where online gambling is explicitly prohibited by law. You accept sole responsibility for determining whether your use of the Services is lawful in your jurisdiction.

3. Deposits, Withdrawals, and Payment Methods

Important: 399bid does not charge fees for deposits or withdrawals. However, your mobile wallet provider (e.g., bKash, Nagad) may apply their own standard transaction charges. These third-party charges are outside 399bid's control and are the sole responsibility of the Member.

  • 4.1 Bonuses must be claimed within the time period specified in the individual promotion. Unclaimed bonuses expire automatically and cannot be reinstated.

  • 4.3 399bid reserves the right to modify, suspend, or cancel any promotion at any time without prior notice. Promotional abuse — including but not limited to collusion, use of multiple accounts, or exploitation of software errors — will result in forfeiture of all bonus funds and may lead to permanent account closure.
  • 4.4 Only one welcome bonus is available per person, per household, per IP address, and per device. Attempts to claim multiple welcome bonuses will be treated as promotional abuse.

5. Gameplay, Betting Rules, and Fair Play

  • 5.1 In the event of a technical malfunction or software error that results in an incorrect game outcome, the affected round or bet will be declared void and the stake returned to the Member. Winnings paid in error due to a software fault will be reclaimed by 399bid.
  • 5.2 Members must not engage in any form of cheating, collusion, match-fixing, arbitrage betting, or use of automated betting software ("bots"). Suspected instances of any such activity will result in immediate account suspension pending investigation and, where confirmed, permanent closure with forfeiture of funds.
  • 5.3 Minimum and maximum stake limits per game or betting market are displayed within the relevant game or market interface. These limits may be amended by 399bid at any time.

6. Key Policy Commitments

A summary of the core commitments 399bid makes to every Member under this Agreement.

Data Security and Privacy

All personal and financial data submitted to 399bid is protected by SSL (Secure Socket Layer) encryption. 399bid will not sell or share your personal data with unaffiliated third parties, except as required by applicable law or as described in our Privacy Policy. Members are encouraged to review the Privacy Policy for full details of data handling practices.

Responsible Gaming Commitment

399bid is committed to promoting responsible gambling.

Full details are available on the Responsible Gaming page.

Account Verification (KYC)

To comply with anti-money laundering obligations and to protect the integrity of the platform, 399bid may request identity verification documents at any point during the account lifecycle — particularly prior to processing withdrawals above a threshold set at 399bid's discretion. Failure to complete verification within a reasonable timeframe will result in withdrawal suspension.

Account Suspension and Closure

399bid reserves the right to suspend, restrict, or permanently close any account at any time and without prior notice if the account is found to be in breach of this Agreement, involved in fraudulent activity, or operating in a jurisdiction where the Services are prohibited. Upon closure for breach, any bonus balances and associated winnings will be forfeited. Real-money balances may be returned subject to satisfactory KYC completion.

Dispute Resolution

In the event of a dispute regarding a bet, game outcome, bonus, or account transaction, Members must contact the 399bid support team in the first instance via the live chat facility available from within the logged-in platform. 399bid will investigate all disputes in good faith and aim to provide a written response within five (5) business days.
