399days Terms & Conditions — Please read in full before using the platform.

Please read these Terms & Conditions carefully before registering or using 399days. They cover everything related to membership, payments, bonuses, responsible gaming, and account management.


Key Points

The Six Core Pillars of 399days Terms & Conditions

Our Terms & Conditions are built around six key principles — to ensure transparency and protection for all members.

Membership & Eligibility

You must be at least 18 years old to open an account with 399days. Each person may hold only one account — duplicate accounts may result in both being permanently closed.

Bonus & Promo Terms

All bonuses come with wagering requirements. Withdrawals are not permitted until the specified conditions are met before the bonus is granted. 399days communicates all terms clearly.

Payment & Withdrawal Policy

Deposits and withdrawals are available via mobile banking and bank transfer. Withdrawals can only be made to your registered payment method — transfers to third parties are not permitted.

Account Security

Members are solely responsible for keeping their password and login credentials confidential. Sharing your account or allowing a third party to use it is strictly prohibited.

Responsible Gaming

399days encourages all members to play within their means. Deposit limits, cooling-off periods, and self-exclusion are all available and can be activated at any time.

Prohibited Activities

Fraud, bonus abuse, money laundering, and system manipulation are strictly prohibited. Any such activity detected will result in the immediate suspension of the account.

Important: By creating an account or using 399days services, you are deemed to have fully accepted these Terms & Conditions. Non-compliance may result in account termination.

01 General Terms & Conditions

These Terms & Conditions constitute a legally binding agreement between the 399days platform (https://399days.vu) and its members. Visiting the website, registering an account, or using any of its services indicates your acceptance of these terms.

399days reserves the right to update these Terms & Conditions at any time. Changes will be published on the website and, where applicable, members will be notified. Continued use of the platform after any update constitutes acceptance of the revised terms.

These Terms & Conditions are provided in Bangla. If you need clarification in English or another language, our support team is happy to help.

02 Account Register

Accurate and truthful information is required when registering with 399days. Accounts created with false information may be terminated, and any balance held in such accounts may be forfeited.

  • Each person may hold only one account. If multiple accounts are found, all of them will be closed.
  • Your account is for personal use only and must not be shared with or used by anyone else.
  • The mobile number or email address provided at registration may need to be verified.
  • If your account details change (such as your phone number or payment information), please update them through our support team.

03 Age Verification

You must be at least 18 years old to use 399days services. Minors are strictly prohibited from registering or playing.

399days may request ID or other documents for age verification at any time. Until verification is complete, withdrawals or certain services may be temporarily suspended. This is done solely for the member's protection.

Creating an account or using 399days services on behalf of a minor may be a criminal offence. 399days reserves the right to report such incidents to the relevant authorities.

  • Deposits must be made only from a payment method registered in your own name.
  • Deposits sent from a third-party account will not be accepted and will be returned.
  • If a deposit fails, the amount will be returned automatically. If there is a delay, please contact support.

  • The welcome bonus is available to new members on their first deposit only — it does not apply to existing accounts.
  • Bonus balance cannot be withdrawn before the wagering requirements are fulfilled.
  • Using the same bonus offer across multiple accounts will result in all accounts being closed.
  • Once a bonus expires, the balance is automatically forfeited.
  • 399days reserves the right to modify or cancel any promotional offer at any time.

07 Game & Betting Rules

Each game on 399days has its own set of rules. We recommend reading them before you start playing. All game outcomes are governed by a certified RNG (Random Number Generator) — with no human intervention.

  • Odds in Sports Betting may change at any time — the odds at the moment your bet is confirmed are final.
  • If a game is interrupted due to a technical issue, the affected round may be voided and the stake refunded.
  • Any disputes regarding Live Casino results will be resolved by reviewing the game logs.
  • The use of automated betting software or bots is strictly prohibited.

08 Prohibited Activities

The following activities are strictly prohibited on 399days. If detected, the account will be immediately closed and the balance may be forfeited.

  • Any attempt at fraud, deception, or system manipulation.
  • Bonus abuse — such as collecting bonuses through multiple accounts.
  • Depositing funds obtained through money laundering or illegal sources.
  • Attempting unauthorized access to another member's account.
  • Using bots, scripts, or automated software to play games.
  • Intentionally exploiting any vulnerability or bug in the platform.

09 Responsible Gaming

399days believes gaming should be a source of entertainment. We encourage all members to set their own limits. The following tools are always available on the platform:

  • Deposit Limits: Set daily, weekly, or monthly deposit limits.
  • Cooling-Off Period: Take a break from gaming for a specified period of time.
  • Self-Exclusion: Temporarily close your account for a set period.
  • Reality Check: You will receive reminders about how long you have been playing.

11 Intellectual Property

The 399days website, logo, content, game interfaces, and software are entirely the intellectual property of 399days. Copying, republishing, or commercial use of any part without prior permission is strictly prohibited.

399days reserves the right to amend these Terms & Conditions, in part or in full, at any time. Notice will be posted on the website before changes take effect. For significant updates, members will be notified by email or in-platform notification.

Continued use of the platform after any changes will be treated as acceptance of the updated terms. If you do not agree to the new terms, please contact support to request account closure.

13 Account Closure & Suspension

Members may request account closure at any time. Any available balance should be withdrawn before the account is closed.

399days may suspend or close an account at its own discretion for the following reasons:

  • KYC verification has not been completed, or false information has been provided.
  • Accounts that have been inactive for an extended period (generally more than 12 months).
  • At the direction of a legal or regulatory authority.

If a valid balance remains at the time of account closure, withdrawal is still possible subject to verification.
