Terms & Conditions — 5666b Platform Rules and Player Obligations

01 Introduction and Acceptance

These Terms and Conditions ("Terms") govern the relationship between 5666b ("the Platform", "we", "us", "our") and any individual ("Player", "you", "your") who accesses, registers on, or uses any service provided via the 5666b platform, including its website, mobile interface, casino games, sports betting products, and associated promotional activities.

By creating a 5666b account, clicking to confirm acceptance during registration, making a deposit, or placing a wager, you confirm that you have read, understood, and agree to be bound by these Terms in their entirety. If you do not agree with any part of these Terms, you must not create an account or use the 5666b platform in any capacity.

These Terms should be read alongside the 5666b Privacy Policy and Responsible Gaming Policy, both of which form part of the overall agreement between you and 5666b. In the event of any conflict between these Terms and those documents, these Terms shall prevail unless explicitly stated otherwise.

02 Eligibility Requirements

To register and maintain an account on the 5666b platform, you must satisfy all of the following eligibility criteria at all times:

1. Age: You must be at least 21 years of age. 5666b strictly enforces the 21+ age requirement and will verify your age using your National Identity Card (NID) or other acceptable government-issued identification before processing your first withdrawal.
2. Capacity: You must have full legal capacity to enter into a binding contract under applicable law. You must not be under any legal guardianship or court order that restricts your ability to manage your own financial affairs.
3. Self-Exclusion: You must not be subject to a self-exclusion order on 5666b or on any other gambling platform where cross-platform exclusion agreements may apply. Registering while subject to self-exclusion is a material breach of these Terms.
4. Single Account: You must not already hold an active 5666b account. Each individual is entitled to one account only. Operating multiple accounts simultaneously, or creating a new account after a previous account has been suspended or closed, is prohibited.
5. Not Acting on Behalf of Another: You must be registering and playing on your own behalf. Creating or operating an account on behalf of a third party — including a family member — is strictly prohibited.

03 Account Registration

To access real-money services on the 5666b platform, you must complete the account registration process in full. Registration requires you to provide accurate, current, and complete information including your full legal name, date of birth, residential address, email address, and mobile phone number. You agree to update this information promptly if it changes at any point.

5666b reserves the right to refuse registration to any individual without being required to provide a reason. Registration does not guarantee continued access to the platform. 5666b may, at its absolute discretion, close or suspend any account at any time.

You are solely responsible for maintaining the confidentiality of your login credentials, including your username, password, and any OTP codes associated with your account. You must not share your credentials with any other person under any circumstances. 5666b will never contact you to request your password or OTP code. Any unauthorised use of your account must be reported to 5666b support immediately.

5666b employs OTP-based two-factor authentication for logins from unfamiliar devices. You are strongly advised to enable this feature. 5666b accepts no liability for losses resulting from unauthorised account access where the player has failed to take reasonable steps to protect their credentials.

04 Identity Verification (KYC)

In accordance with its player protection and anti-money laundering obligations, 5666b operates a Know Your Customer (KYC) verification process. You agree to cooperate fully with this process and to provide all documentation requested by 5666b within the timeframe specified in any verification request.

Verification is mandatory before the first withdrawal on any 5666b account. The standard documentation required includes:

• A clear photograph or scanned copy of your Bangladesh National Identity Card (NID) showing your full name and date of birth
• A recent utility bill, bank statement, or mobile wallet statement confirming your residential address (issued within the last three months)
• For withdrawals above ৳50,000, additional source-of-funds documentation may be requested at 5666b's discretion

5666b aims to complete standard KYC reviews within 24 hours of receiving all required documentation. During the verification period, deposits and gameplay are permitted; withdrawals are held pending successful verification. 5666b reserves the right to suspend all account activity, including deposits and gameplay, if a verification request goes unanswered for more than seven calendar days.

Providing false, altered, or fraudulent documentation in connection with the KYC process is a serious breach of these Terms and will result in immediate, permanent account closure. Any balances held on such accounts will be forfeited.

05 Deposits and Payments

5666b accepts deposits via the following payment methods: bKash, Nagad, Rocket, Upay, Visa, and Mastercard. All transactions on the platform are denominated in Bangladeshi Taka (৳ BDT). No currency conversion fees are charged by 5666b on BDT-denominated transactions. Your mobile wallet or card provider may apply their own transaction fees, which are outside 5666b's control.

Deposit limits are as follows:

• Minimum deposit via mobile wallet (bKash, Nagad, Rocket, Upay): ৳200
• Minimum deposit via card (Visa, Mastercard): ৳500
• Maximum single deposit: ৳200,000 (subject to payment provider limits)
• Daily deposit limit: ৳500,000 unless a lower limit has been set by the player via responsible gaming controls

You may only deposit funds from a payment account registered in your own name. Deposits made from third-party accounts will be returned to the source and the associated game activity may be voided. 5666b reserves the right to request evidence confirming ownership of the payment method used.

06 Withdrawals

Withdrawal requests on 5666b are subject to the following conditions:

1. Minimum withdrawal: ৳500 per transaction.
2. Maximum withdrawal: ৳500,000 per day unless a higher limit has been approved in writing by 5666b compliance staff.
3. Method: Withdrawals are processed to the same payment method used for your most recent qualifying deposit. 5666b does not process withdrawals to third-party accounts or payment methods not previously used for a deposit on the same account.
4. Processing time: Withdrawal requests submitted before 21:00 Bangladesh Standard Time (BST, UTC+6) on any day are processed the same day. Requests submitted after 21:00 BST are processed on the following business day. Target processing time is within two hours of the request being approved.
5. KYC prerequisite: KYC verification must be completed in full before any withdrawal is released from the 5666b platform. Incomplete verification will result in a withdrawal hold until documentation is provided and reviewed.
6. Bonus wagering: Where a withdrawal request includes bonus-derived funds, all applicable wagering requirements must be met before those funds are eligible for withdrawal. Real-money funds deposited by the player are not subject to wagering requirements and may be withdrawn at any time, subject to the other conditions in this section.

5666b reserves the right to conduct enhanced due diligence on any withdrawal request, particularly for high-value or unusual transactions. In such cases, 5666b may request additional documentation, which must be provided within 48 hours. Failure to provide requested documentation within this period may result in the withdrawal request being held pending compliance review.

07 Bonuses and Promotions

5666b offers a range of bonuses, free bets, promotional credits, and loyalty rewards to eligible players. All bonuses are subject to the specific terms attached to each offer, which will be published at the time the promotion is active. The following general bonus terms apply across all 5666b promotions unless a specific promotion's terms expressly state otherwise:

• Bonus funds and free bets are credited to your account only after the qualifying deposit or action has been completed and verified.
• Bonus funds are held separately from real-money funds in your account wallet. Real-money funds are used first in gameplay unless the specific bonus terms direct otherwise.
• Standard wagering requirement for deposit match bonuses: 20x the combined deposit and bonus amount, unless stated otherwise on the promotion page.
• Wagering contributions vary by game type: slots typically contribute 100%; live casino games contribute between 10% and 20%; sports bets at odds of 1.50 or greater contribute 100%.
• Bonuses must be used within the validity period stated in the promotion terms. Expired bonus funds are forfeited without compensation.
• 5666b reserves the right to withdraw, modify, or cancel any bonus or promotion at any time without prior notice, provided that existing wagering progress on active bonuses is honoured up to the point of cancellation.
• Any attempt to exploit bonus offers through bonus abuse, arbitrage, or multi-accounting will result in immediate forfeiture of all bonus funds and associated winnings, and may result in account suspension.

08 Game Rules and Fair Play

All casino games available on the 5666b platform are supplied by internationally certified game providers including Evolution Gaming, Pragmatic Play, NetEnt, Microgaming, Spribe, and Ezugi. Each game operates according to the rules published by its respective provider, which are accessible within the game interface. 5666b does not modify game logic, payout structures, or RNG outcomes.

All game outcomes are determined by certified random number generators (RNG) independently audited by recognised testing laboratories. Return-to-player (RTP) percentages and volatility ratings are displayed within each game's information panel. 5666b does not guarantee specific outcomes or profit levels from any game.

In the event of a technical malfunction during a game round — including disconnection, server error, or power failure on the player's side — the following rules apply:

• If a game round has been fully resolved by the provider's server before the disconnection, the result stands and the outcome is recorded in your account history.
• If a game round was interrupted before resolution, 5666b will investigate the incident and credit any winnings that can be verified from server logs within 72 hours.
• 5666b accepts no liability for disconnections caused by the player's internet service provider, mobile network, device failure, or power outage.

09 Sports Betting Rules

Sports betting on 5666b covers cricket (BPL, IPL, T20 World Cup, Bangladesh Tigers fixtures), football, kabaddi, and hockey, with pre-match and in-play markets available. The following rules apply to all sports bets placed on the platform:

• Minimum bet: ৳100 per selection.
• Maximum bet limits vary by market, sport, and event; limits are displayed at the point of bet placement and may be adjusted by 5666b at any time.
• In-play odds are subject to delays and may be suspended or withdrawn at any time without notice. Bets accepted during a suspension window are void.
• 5666b reserves the right to void any bet placed on incorrect odds resulting from a manifest error, regardless of whether the bet has been confirmed. Players will be notified and their stake returned in full.
• For cricket, ball-by-ball in-play markets settle according to the outcome of the ball in question as confirmed by the official scorer. Disputes regarding ball-by-ball settlements must be raised within 24 hours of the event concluding.
• Abandoned or postponed events are treated as void, and stakes are returned to the player's account, unless the event is resumed and completed within 48 hours of the original scheduled start time.
• Winnings from settled bets are credited to your 5666b wallet on the same day as match settlement, generally within two hours of the official result being confirmed.

10 Prohibited Conduct

The following actions constitute a material breach of these Terms and may result in immediate account suspension, permanent closure, and forfeiture of account balances:

1. Fraud and Deception: Providing false personal information, using stolen payment credentials, fraudulent charge-backs, or misrepresenting your identity in any way.
2. Multi-Accounting: Creating, operating, or benefiting from more than one 5666b account, regardless of the purpose.
3. Collusion: Cooperating with other players in poker or any other game to gain an unfair advantage, including chip dumping, seat reservation abuse, or coordinated soft-play.
4. Bonus Abuse: Any systematic exploitation of bonuses, free bets, or promotions including coordinated abuse across multiple accounts or devices.
5. Automated Play: Using bots, scripts, macros, or any automated tool to interact with the platform in place of genuine manual play.
6. Arbitrage and Match Betting: Placing offsetting bets on the same event across multiple accounts or platforms to guarantee profit regardless of outcome.
7. Money Laundering: Using the 5666b platform to deposit, transfer, or withdraw funds derived from illegal activity, or to obscure the source of funds. All suspicious activity is reported to appropriate authorities.
8. Exploitation of Errors: Deliberately exploiting software bugs, pricing errors, or system vulnerabilities for financial gain. Any winnings derived from exploiting a known error are void.

11 Account Suspension and Closure

5666b reserves the right to suspend or close any account at its absolute discretion, with or without prior notice. Circumstances that may result in account suspension or closure include, but are not limited to, any of the prohibited conduct listed in Section 10, failure to complete KYC verification, and suspected fraudulent activity.

Where an account is suspended for investigation, all pending withdrawals and active game sessions will be paused until the investigation is concluded. 5666b will aim to complete investigations within 14 calendar days, though complex cases may take longer. The player will be informed of the outcome and, where applicable, of any action taken.

Where an account is closed by the player voluntarily, any verified real-money balance remaining in the account will be returned to the player's registered payment method within five business days. Bonus funds are forfeited upon voluntary account closure unless they have already met the applicable wagering requirement.

Where an account is closed by 5666b as a result of a breach of these Terms, the platform reserves the right to retain the account balance as partial or full compensation for any losses, costs, or damages arising from the breach.

12 Responsible Gaming

5666b is committed to promoting responsible gambling and providing tools that keep gaming a form of entertainment. The following responsible gaming controls are available to every account holder via the account settings panel:

• Deposit Limits: Set daily, weekly, or monthly deposit caps. Limit reductions take effect immediately. Limit increases require a 72-hour cooling-off period before taking effect.
• Session Reminders: Configure time-based notifications that alert you when you have been actively playing for a specified duration.
• Reality Checks: Enable periodic on-screen prompts that display your net gaming position and session duration at intervals you select.
• Self-Exclusion: Initiate a temporary self-exclusion period of between 24 hours and six months. Self-exclusion is immediate and irrevocable within the chosen period — it cannot be reversed by contacting support. Permanent self-exclusion is also available on request.

If you feel that your gambling is no longer under your control, we encourage you to use the self-exclusion tool immediately and to contact our support team via WhatsApp or email. For more detailed guidance, please visit the 5666b Responsible Gaming page. The 21+ age restriction is a fundamental part of 5666b's responsible gaming programme and is enforced at the withdrawal stage via NID verification.

13 Limitation of Liability

To the fullest extent permitted by applicable law, 5666b's total aggregate liability to any player for any claim arising out of or in connection with the use of the platform — whether in contract, tort, breach of statutory duty, or otherwise — shall not exceed the total net deposits made by that player in the 90-day period preceding the event giving rise to the claim.

5666b shall not be liable for any indirect, consequential, special, incidental, or punitive losses or damages, including but not limited to loss of profit, loss of opportunity, loss of data, or loss of goodwill, even if 5666b has been advised of the possibility of such damages.

5666b does not accept liability for losses arising from: interruptions to the platform caused by third-party infrastructure providers; force majeure events including natural disasters, civil unrest, or telecommunications failures; or the player's failure to follow platform instructions or use available responsible gaming tools.

When material changes are made, 5666b will notify registered players via email or an in-platform notification at least seven days before the changes take effect. Continued use of the platform after the effective date of any amendment constitutes acceptance of the revised Terms.
