Terms & Conditions for
5777b — Bangladesh's Betting Platform

1. Acceptance of Terms

By accessing the 5777b website at 5777b.io, creating a player account, making a deposit, placing a bet, or participating in any game or promotion offered by 5777b, you confirm that you have read these Terms and Conditions in their entirety and that you agree to be bound by them. These terms apply to all users of the platform, regardless of how they access it — whether through a desktop browser, mobile browser, or any other device.

These Terms and Conditions are effective as of 01 January 2026 and supersede all prior versions. 5777b reserves the right to update or amend these terms at any time. Where material changes are made, 5777b will endeavour to notify registered players via the email address on file. Continued use of the platform following the publication of any amended terms constitutes acceptance of those changes.

If you are accessing 5777b on behalf of another person or entity, you represent that you have the authority to bind that person or entity to these terms, and references to "you" in these terms shall apply to that person or entity accordingly.

2. Eligibility

To register and maintain an account on 5777b, you must satisfy all of the following eligibility requirements at all times:

• You must be at least 21 years of age. 5777b strictly prohibits the use of its platform by individuals under the age of 21.
• You must be acting on your own behalf as a private individual and not as an agent, representative, or employee of any commercial entity.
• You must not be accessing the platform from a jurisdiction where online gambling is explicitly prohibited by applicable law.
• You must not be subject to any self-exclusion agreement, whether voluntary or enforced, that restricts your participation in online gambling activities.
• You must have full legal capacity to enter into a binding agreement under the laws applicable to your place of residence.

5777b reserves the right to refuse registration or close any account where it reasonably believes the eligibility criteria have not been or are no longer being met. This includes but is not limited to circumstances where the platform has reason to believe the player is under 21 years of age.

3. Account Registration

To access the full range of services offered by 5777b, players must register a personal account. Registration is free of charge. During the registration process, you will be required to provide certain personal information including your full legal name, date of birth, email address, and mobile number. All information provided must be accurate, complete, and current.

3.1 Single Account Policy

Each individual is permitted to hold one and only one active account on the 5777b platform. Creating more than one account — whether using the same or different personal details — is a violation of these terms. Where duplicate accounts are identified, 5777b reserves the right to close all but the original account, void any bets or winnings associated with secondary accounts, and suspend the player's ability to register again.

3.2 Account Security

You are solely responsible for maintaining the confidentiality of your account credentials, including your username and password. You must not share your login details with any other person. If you suspect that your account has been accessed without your authorisation, you must notify 5777b immediately by contacting support at [email protected]. 5777b will not be liable for any loss or damage arising from your failure to protect your account credentials.

3.3 Account Verification (KYC)

As part of our commitment to platform security and compliance with applicable anti-money laundering obligations, 5777b may require players to complete a Know Your Customer (KYC) verification process. This process may require the submission of:

• A valid government-issued photo identity document (e.g., National ID Card, Passport, or Driving Licence).
• Proof of address (e.g., a recent utility bill, bank statement, or government correspondence dated within 90 days).
• Proof of payment method ownership (e.g., a screenshot of a bKash or Nagad account registered in the player's name).

Withdrawals may be withheld until KYC verification is satisfactorily completed. 5777b processes verification documents securely and in accordance with its Privacy Policy.

4. Deposits & Withdrawals

5777b supports a range of payment methods tailored for players in Bangladesh. Accepted deposit and withdrawal methods include bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, and Islami Bank, among others. The availability of specific payment methods may vary from time to time and 5777b does not guarantee the permanent availability of any particular method.

4.1 Deposits

The minimum deposit amount on 5777b is ৳500. There is no maximum deposit limit for standard verified accounts, though 5777b may apply transaction limits at its discretion for security purposes. Deposits made via bKash, Nagad, Rocket, and Upay are typically credited to the player's account within minutes of the transaction being completed. Deposits made via bank transfer may take longer to process depending on the relevant financial institution's operating hours.

All deposits must be made from a payment account registered in the player's own name. Third-party deposits — where the payment source belongs to a person other than the account holder — are strictly prohibited and will result in a refund to the source account and may lead to the suspension of the player's 5777b account.

4.2 Withdrawals

Withdrawal requests are processed subject to the following conditions:

• The player's account must be fully verified (KYC completed) before any withdrawal can be processed.
• The minimum withdrawal amount is ৳1,000.
• Withdrawals will be returned to the same payment method used for the most recent deposit, wherever technically possible.
• Active bonus funds that have not met the applicable wagering requirements cannot be withdrawn.
• Withdrawals to bKash and Nagad for fully verified accounts are typically processed same-day during Bangladesh Standard Time (BST, UTC+6) business hours.
• Withdrawals to bank accounts are typically processed within 1–3 business days.

4.3 Currency

All transactions on 5777b are conducted in Bangladeshi Taka (BDT, symbol ৳). 5777b does not accept deposits in foreign currencies. Any funds deposited in a currency other than BDT will be declined or returned to the source account.

5. Bonuses & Promotions

5777b offers promotional bonuses to eligible players from time to time, including but not limited to welcome bonuses, reload bonuses, free bets, and tournament prizes. All bonuses are subject to the specific terms and conditions published alongside each offer at the time the offer is made available. In the event of any conflict between the general terms in this section and the specific terms of an individual promotion, the specific promotional terms shall prevail.

5.1 General Bonus Conditions

• Bonuses are available to players who have registered a verified account and met any eligibility criteria stated in the relevant promotion.
• Unless otherwise specified, each bonus may be claimed once per player, per household, per IP address, and per payment method.
• Bonus funds are credited to a separate bonus balance and must be wagered the required number of times before they may be converted to withdrawable cash.
• Wagering requirements must be completed within the timeframe specified for each promotion. Bonus funds that expire before wagering requirements are met will be forfeited.
• 5777b reserves the right to withdraw a bonus offer, modify its terms, or cancel a bonus at any time if there is reasonable suspicion of abuse or misuse.

5.2 Bonus Abuse

Any player found to be engaging in bonus abuse — including but not limited to creating multiple accounts to claim bonuses repeatedly, placing low-risk or zero-risk bets specifically to fulfil wagering requirements, or using automated tools to exploit promotional offers — will have their bonuses voided and their account suspended. 5777b takes a zero-tolerance approach to promotional fraud.

6. Betting Rules

All sports bets placed on 5777b are subject to the specific rules applicable to the sport and market in question, as published in the 5777b Sportsbook Rules. The following general rules apply to all bets placed on the platform:

• Bets are accepted at the odds displayed at the time the bet is confirmed. Once a bet slip has been accepted and a confirmation reference issued, the odds are locked and cannot be changed.
• 5777b reserves the right to void any bet placed on an event that has already commenced or where the outcome was known at the time of placement.
• In the event of a technical error resulting in the display of clearly incorrect odds (e.g., odds that are manifestly out of line with the prevailing market), 5777b reserves the right to void affected bets and refund the original stake to the player's account.
• Maximum bet limits apply to all markets. These limits may vary by sport, event, market type, and player account status. 5777b reserves the right to reduce maximum bet limits for any player at any time without notice.
• Minimum bet amount: ৳50 per bet slip.

7. Casino & Games

5777b's casino and games offering — including live dealer tables, slots, and crash games — is provided through partnerships with third-party game studios and software providers including Evolution Gaming, Ezugi, Pragmatic Play, NetEnt, Microgaming, and Spribe. All games use certified Random Number Generator (RNG) technology and are subject to the technical specifications and rules set by the respective game provider.

The Return to Player (RTP) percentages applicable to individual slot and casino games are set by the game provider and are available within the game information panel for each title. 5777b does not alter the RTP of any game supplied by a third-party provider.

In the event of a disconnection or technical fault occurring during an active game round, 5777b's server logs will be used to determine the state of the game at the time of the interruption. Where a game round cannot be completed, the player's stake for that round will be refunded to their account balance. 5777b will not be liable for interrupted sessions caused by factors outside its control, including but not limited to the player's internet connection, device failure, or power outage.

8. Prohibited Conduct

The following activities are strictly prohibited on the 5777b platform. Engaging in any of the following may result in immediate account suspension, the voiding of bets and winnings, and the forfeiture of account balances:

• Using automated software, bots, scripts, or any other non-human means to interact with the platform, place bets, or access account features.
• Colluding with other players, dealers, or any third party to gain an unfair advantage in any game or market.
• Exploiting software bugs, glitches, or errors in the platform or any third-party game to gain an advantage. Any winnings obtained through exploitation of errors will be voided.
• Engaging in arbitrage betting strategies that exploit discrepancies between 5777b's odds and those of other platforms.
• Using the platform for any form of money laundering or other financial crime.
• Providing false, misleading, or fraudulent identity, payment, or account information.
• Accessing or attempting to access another player's account without their explicit consent.
• Threatening, harassing, or abusing 5777b staff or other players via any communication channel.

5777b does not warrant that the platform will be available without interruption, error, or security breach at all times.
