Last updated: 1 January 2025

What You Need to Know Before You Start

These are the most important things to understand about using 3666. The full terms follow below — please read those too.

You Must Be 18 or Older

3666 is strictly for adults. You must be at least 18 years old to register an account or place any bets on the platform. We verify age during registration and reserve the right to request documentation at any time.

One Account Per Person

Each player is permitted one account on 3666. Creating multiple accounts — whether under your own name or someone else's — is a breach of these terms and will result in all accounts being suspended and balances forfeited.

Withdrawals to Your Own Account Only

All withdrawals from 3666 must go to a bKash, Nagad, or Rocket account registered in your own name. We do not process withdrawals to third-party accounts under any circumstances.

Bonuses Have Wagering Requirements

All bonuses and promotional credits on 3666 are subject to wagering requirements before they can be withdrawn. The specific requirements for each promotion are stated clearly in the promotion details at the time of the offer.

Fraudulent Activity Is Prohibited

Any attempt to exploit technical errors, use automated software, collude with other players, or manipulate game outcomes on 3666 will result in immediate account suspension and forfeiture of all funds held in the account.

You Are Responsible for Your Account

You are responsible for keeping your 3666 login credentials secure. Do not share your password with anyone. 3666 is not liable for losses resulting from unauthorised access to your account caused by your failure to keep your credentials private.

Important: These Terms and Conditions form a legally binding agreement between you and 3666. By accessing or using the 3666 platform at 3666.onl, you confirm that you have read, understood, and agreed to these terms in full. If you do not agree, you must not use the platform.

1 Acceptance of Terms

These Terms and Conditions ("Terms") govern your access to and use of the 3666 online gaming platform, available at 3666.onl ("the Platform"). By registering an account, making a deposit, or placing a bet on 3666, you confirm that you have read these Terms in full and agree to be bound by them.

These Terms apply to all users of 3666, including registered players, visitors browsing the platform, and anyone who accesses any part of the 3666 website or mobile application. If you are using 3666 on behalf of another person, you confirm that you have the authority to bind that person to these Terms.

3666 reserves the right to update or amend these Terms at any time. When changes are made, the updated Terms will be published on this page with a revised "last updated" date. Your continued use of 3666 after any changes are published constitutes your acceptance of the revised Terms.

Plain language summary: Using 3666 means you agree to these rules. If you don't agree, don't use the platform. We'll let you know when the rules change, and continuing to use 3666 after that means you accept the new version.

2 Eligibility

To register and use 3666, you must meet all of the following eligibility requirements:

  • You must be at least 18 years of age at the time of registration.
  • You must be a natural person — corporate entities may not register accounts on 3666.
  • You must not be a resident of any jurisdiction where online gaming is prohibited by law.
  • You must not be an employee, contractor, or immediate family member of an employee or contractor of 3666 or any of its affiliated companies.
  • You must not be subject to any self-exclusion order or voluntary exclusion agreement that covers the 3666 platform.
  • You must have the legal capacity to enter into a binding agreement under the laws applicable to you.

3666 reserves the right to verify your eligibility at any time. If you are found to be ineligible, your account will be suspended and any pending withdrawals may be withheld pending investigation. Deposits made by ineligible players may be returned at 3666's discretion, but winnings generated during an ineligible period will be forfeited.

Age verification: 3666 takes underage gambling seriously. If we have reason to believe that a player is under 18, we will suspend the account immediately and conduct a full review before any funds are released.

3 Account Registration

To access real-money games on 3666, you must register an account. During registration, you are required to provide accurate, complete, and up-to-date information. This includes your full name, date of birth, mobile number, and any other information requested by 3666 during the registration process.

You are permitted to hold only one account on 3666. If you already have an existing account, you must not create a new one. Duplicate accounts will be merged or closed, and any bonuses claimed across multiple accounts will be voided.

You are responsible for maintaining the confidentiality of your 3666 login credentials. Do not share your username or password with anyone. If you suspect that your account has been accessed without your authorisation, contact 3666 support immediately at [email protected].

  • All information provided during registration must be truthful and accurate.
  • You must update your account details promptly if any information changes.
  • 3666 may require identity verification documents before processing withdrawals or at any other time.
  • Accounts registered with false information may be closed without notice and balances forfeited.

4 Deposits and Payments

3666 accepts deposits via bKash, Nagad, and Rocket. All deposits must be made from a mobile banking account registered in your own name. Third-party deposits — where the payment account belongs to someone other than the registered 3666 account holder — are not permitted and will be returned where possible or held pending investigation.

Deposits on 3666 are processed in real time. Once a deposit is confirmed by the payment provider, the funds will appear in your 3666 account balance immediately. If a deposit does not appear within 30 minutes, contact our support team with your transaction reference number.

  • Minimum deposit amounts are displayed at the time of transaction and may vary by payment method.
  • 3666 does not charge fees on deposits, but your mobile banking provider may apply their own charges.
  • Deposits made in error cannot always be reversed — contact support as quickly as possible if you make a mistake.
  • 3666 reserves the right to refuse or reverse any deposit that it reasonably suspects is connected to fraudulent activity.

Note: All transactions on 3666 are processed in Bangladeshi Taka (BDT). There is no currency conversion involved when using bKash, Nagad, or Rocket.

5 Withdrawals

You may request a withdrawal of your available balance at any time, subject to the conditions set out in these Terms. Withdrawals on 3666 are processed to the same payment method used for your most recent deposit, and must go to an account registered in your own name.

3666 aims to process all withdrawal requests within minutes of approval. However, processing times may be longer during periods of high demand or if your account is subject to a verification review. 3666 is not responsible for delays caused by your mobile banking provider once the funds have been dispatched from our end.

  • Withdrawal requests will not be processed until any applicable wagering requirements on bonus funds have been met.
  • 3666 may request identity verification documents before approving a withdrawal, particularly for first-time withdrawals or large amounts.
  • Minimum and maximum withdrawal limits apply and are displayed in the withdrawal section of your account.
  • Withdrawals to third-party accounts will not be processed under any circumstances.
  • 3666 reserves the right to delay or withhold a withdrawal if there is reasonable suspicion of fraudulent activity or a breach of these Terms.

6 Bonuses and Promotions

3666 offers bonuses and promotional credits to both new and existing players from time to time. All bonuses are subject to the specific terms stated at the time the offer is made, as well as the general bonus conditions set out here.

Unless stated otherwise in the specific promotion terms, the following general conditions apply to all bonuses on 3666:

  • Bonus funds must be wagered a minimum number of times before they can be withdrawn. The wagering requirement for each promotion is stated clearly in the offer details.
  • Only one bonus may be active on your account at a time unless 3666 explicitly states otherwise.
  • Bonuses are non-transferable and have no cash value until wagering requirements are met.
  • 3666 reserves the right to withdraw a bonus offer at any time before it has been claimed.
  • If 3666 determines that a bonus has been claimed in bad faith or through abuse of the promotion system, the bonus and any winnings derived from it will be voided.
  • Bonus expiry dates apply — unused bonus funds will be removed from your account after the stated expiry period.

Our approach to bonuses: 3666 designs its promotions to be genuinely achievable for regular players. We don't set wagering requirements that are impossible to meet in practice. If you have a question about a specific bonus, contact our support team before claiming it.

7 Gameplay Rules

All games available on 3666 — including Mega Fishing, Happy Fishing, Fortune Tiger, Fortune Snake, Rummy, Teen Patti 20-20, and all other titles in the lobby — are governed by their individual game rules, which are accessible within each game. In the event of a conflict between individual game rules and these Terms, these Terms take precedence.

All games on 3666 use certified Random Number Generator (RNG) systems to ensure fair and unpredictable outcomes. 3666 does not manipulate game results and has no ability to influence individual game outcomes once a round has begun.

  • Bets placed and confirmed cannot be cancelled or reversed once a game round has started.
  • In the event of a technical error during a game round, 3666 will investigate and resolve the issue as fairly as possible. Bets affected by a verified technical error may be voided and stakes returned.
  • 3666 is not responsible for losses resulting from a player's misunderstanding of game rules.
  • Minimum and maximum bet limits apply to all games and are displayed within the game interface.

8 Prohibited Conduct

The following activities are strictly prohibited on 3666. Engaging in any of these activities will result in immediate account suspension and may result in legal action:

  • Using automated software, bots, scripts, or any other tool to interact with 3666 games or systems without human input.
  • Colluding with other players to gain an unfair advantage in any game.
  • Exploiting software bugs, glitches, or errors in 3666's systems for financial gain.
  • Using stolen, fraudulent, or unauthorised payment methods to make deposits.
  • Attempting to launder money or use 3666 for any illegal financial activity.
  • Creating multiple accounts to claim bonuses more than once.
  • Providing false information during registration or identity verification.
  • Accessing 3666 from a jurisdiction where online gaming is prohibited by law.
  • Harassing, threatening, or abusing 3666 staff or other players.

Consequences: Any account found to be engaged in prohibited conduct will be suspended immediately. Balances held in suspended accounts may be forfeited in full. 3666 cooperates with law enforcement authorities and will provide account information when required by law.

9 Account Suspension and Closure

3666 reserves the right to suspend or close any account at any time, with or without prior notice, if it has reasonable grounds to believe that the account holder has breached these Terms or engaged in any activity that is harmful to 3666 or other players.

You may also request the closure of your own account at any time by contacting 3666 support. If you close your account voluntarily, any remaining balance will be returned to your registered payment method after any applicable verification checks have been completed.

  • Accounts suspended for breach of Terms may have their balances withheld pending investigation.
  • 3666 will notify you of an account suspension by email or in-app message where possible, but is not obligated to do so in cases involving suspected fraud.
  • If you believe your account has been suspended in error, contact support at [email protected] with your account details and a description of the issue.

10 Limitation of Liability

3666 provides its platform on an "as is" basis. While we work hard to keep the platform running smoothly and reliably, we cannot guarantee uninterrupted access or error-free operation at all times.

To the maximum extent permitted by applicable law, 3666 shall not be liable for:

  • Any loss of funds resulting from a player's own decisions or misunderstanding of game rules.
  • Losses caused by interruptions to the platform due to maintenance, technical failures, or circumstances beyond our control.
  • Delays in payment processing caused by third-party payment providers.
  • Unauthorised access to a player's account resulting from the player's failure to keep their credentials secure.
  • Any indirect, consequential, or incidental losses arising from the use of 3666.

Nothing in these Terms limits 3666's liability for fraud, gross negligence, or any other liability that cannot be excluded by law.

11 Privacy

3666 collects and processes personal data in accordance with our Privacy Policy, which is available at /privacy-policy. By registering an account on 3666, you consent to the collection and use of your personal data as described in that policy.

3666 does not sell your personal data to third parties. We share data only where necessary to process payments, verify identity, or comply with legal obligations. For full details on how we handle your data, please read our Privacy Policy.

12 Responsible Gaming

3666 is committed to promoting responsible gaming. We provide tools to help players manage their gaming activity, including deposit limits, session time reminders, and self-exclusion options. These tools are available in your account settings or by contacting our support team.

If you feel that your gaming is becoming a problem, we encourage you to use these tools or contact our support team for assistance. Full details of our responsible gaming programme are available on our Responsible Gaming page.

  • Gaming on 3666 should be treated as entertainment, not as a source of income.
  • Never chase losses — if you are on a losing streak, take a break.
  • Set a budget before you start playing and stick to it.
  • If you need to take a break, use the self-exclusion feature — our support team will action your request immediately.

13 Changes to These Terms

3666 may update these Terms and Conditions at any time. When we make changes, we will update the "last updated" date at the top of this page. For significant changes, we may also notify registered players by email or in-app notification.
