2 Account Registration and Eligibility

2.1 Age Eligibility

To register on the 3666bet platform and participate in any gaming or betting activity, the user must be at least 21 (twenty-one) years of age. Accounts belonging to underage users will be closed immediately and the associated funds may be forfeited.

2.3 Identity Verification (KYC)

3666bet may at any time request a national identity card, passport, or other documents to verify a user's identity. The Platform reserves the right to hold withdrawals until verification is complete. Attempting identity verification with false information will result in account closure.

3 Account Management and Security

3.1 Login Credential Security

The user is solely responsible for keeping their username and password confidential. Login credentials should not be shared with anyone. The user is solely responsible for all activities that occur on their account.

If you suspect unauthorised access to your account, notify the 3666bet support team immediately. Support is available 24/7 via live chat or email.

3.2 Account Suspension and Closure

3666bet reserves the right to investigate, suspend, or close any account in the following circumstances:

  • Breach of any provision of these Terms.
  • Fraudulent or suspicious activity.
  • Attempting to exploit technical errors on the Platform.
  • Use of bots or automated software.
  • Attempts to gain unauthorised access to another user's funds or information.

3.3 Inactive Accounts

An account may be marked as inactive if there are no transactions for 12 consecutive months. A maintenance fee may be deducted from the balance of an inactive account — the user will be notified in advance where applicable.

4 Financial Transactions: Deposits and Withdrawals

4.1 Deposits

The minimum deposit amount at 3666bet is ৳200. Accepted deposit methods are: bKash, Nagad, Rocket, and bank transfer (major commercial banks including Dutch-Bangla Bank, BRAC Bank, and Islami Bank). Deposits from third-party accounts are not permitted — the deposit source must be the user's own registered account.

Deposits or withdrawals in cryptocurrency or any other digital currency are strictly prohibited. Funds deposited through unauthorised methods may be forfeited.

4.2 Withdrawals

The minimum withdrawal amount is ৳800. Withdrawal requests are generally processed within 15 minutes to 2 hours. Withdrawals can only be made through the same method used for the original deposit — bKash, Nagad, Rocket, or bank transfer.

Withdrawals may be held if identity verification has not been completed or if an investigation is ongoing on the account. Users will be given the opportunity to withdraw available eligible funds before an account is closed.

4.3 Currency

All transactions will be conducted in Bangladeshi Taka (৳). Deposits or withdrawals in foreign currency are not permitted.

5 Bonuses and Promotional Offers

5.1 Welcome Bonus

New users will receive a 200% bonus on their first deposit, up to a maximum of ৳15,000. This bonus can be withdrawn after completing a wagering requirement of 20 times the total bonus amount.

For example: depositing ৳1,000 will earn a ৳2,000 bonus, making the total balance ৳3,000. To withdraw this bonus, a wagering amount of ৳2,000 × 20 = ৳40,000 must be completed.

5.2 Bonus Usage Rules

  • A user may receive the welcome bonus only once.
  • Bonus funds cannot be withdrawn directly — completing the specified wagering requirement is mandatory.
  • Claiming bonuses on multiple accounts from the same household, device, or IP address is prohibited.
  • 3666bet reserves the right to forfeit bonuses if bonus abuse is suspected.
  • The validity period of a bonus is 30 days from the date of issue — it will be cancelled automatically after that.

5.3 Other Promotions

3666bet offers VIP cashback and weekly offers from time to time. Each offer has its own terms and conditions, which will be communicated separately at the time the offer is made. All promotions may be changed or cancelled at any time at 3666bet's discretion.

6 Betting and Gaming Rules

6.1 General Gaming Rules

All games and betting activities are conducted in accordance with the rules set by the 3666bet platform. If a technical error occurs in any game, the relevant round may be declared void and the wagered amount will be refunded.

6.2 Sports Betting

In sports betting, if the odds change after a bet has been accepted, the odds at the time the bet was placed remain final. If betting closes before a match begins, no further bets can be placed. If an event is cancelled, the amount wagered on that bet will be refunded.

6.3 Live Betting

In live betting, odds may change due to network delays. The data recorded on the Platform's server will be considered final. 3666bet is not responsible for any bet missed due to loss of internet connection.

6.4 Maximum Payout Limit

A maximum payout limit from a single bet may apply to certain games or events. This limit varies by game type and will be displayed in the game interface where applicable.

The following activities are strictly prohibited on the 3666bet platform:

  • Placing bets or playing games using bots, scripts, or automated software.
  • Collecting bonuses through fraudulent means ("bonus hunting").
  • Risk-free betting across multiple accounts ("arbitrage").
  • Attempting to gain unauthorised access to another user's account.
  • Attempting to hack, crack, or reverse-engineer the Platform's software.

If any of the above activities are detected, the account will be closed immediately, the associated funds will be forfeited, and legal action may be taken if necessary.

8 Responsible Gaming and Self-Exclusion

3666bet believes that online gaming should be used for entertainment purposes only. In line with the site's Responsible Gaming guidelines, every user is encouraged to be aware of their own gaming limits.

8.1 Setting Deposit Limits

Users can set daily, weekly, or monthly deposit limits on their account. Reducing a limit takes effect immediately; increasing a limit is subject to a 72-hour waiting period.

8.2 Self-Exclusion

A user may voluntarily close their account for a set period (from 30 days up to permanently). During the self-exclusion period, all promotional communications will also be stopped.

8.3 Age Verification

3666bet will not provide services to any user unless they are confirmed to be 21 or older. The use of parental control tools is recommended to protect minors.

9 Privacy and Data Protection

3666bet is committed to protecting users' personal information. Full details of how data is collected, stored, and used are provided in the site's Privacy Policy.

All data transmission is secured using SSL encryption technology. User data is not sold or shared with third parties without authorisation. Data may be shared with authorities if required by legal obligation or for fraud investigation.

10 Limitation of Liability

10.1 Service Availability

3666bet endeavours to ensure uninterrupted service as far as possible. However, temporary disruptions may occur due to maintenance, server upgrades, or unforeseen technical issues. The Platform will not be held liable for any loss arising from such disruptions.

10.2 Third-Party Software

Game providers used on the Platform (such as Pragmatic Play, PG Soft, JILI, Evolution, etc.) have their own terms of service. 3666bet is not directly liable for any errors in their software; however, every effort will be made to assist users in protecting their interests.

10.3 Liability for Financial Loss

Winning and losing in gaming or betting is entirely the user's own responsibility. 3666bet is not liable for any direct or indirect financial loss resulting from use of the Platform, unless the loss is directly caused by a technical error on the Platform.

11 Changes to Terms and Termination

11.1 Right to Make Changes

3666bet reserves the right to partially or fully modify these Terms at any time. For significant changes, users will be given at least 7 days' notice — via email or a Platform notification.

If the user continues to use the Platform after the updated Terms have been published, they will be considered to have accepted the new terms.

11.2 Termination of Agreement

A user may terminate this agreement at any time by closing their account. In that case, any eligible funds in the account will be returned, but bonus funds will be considered void.
