Terms and Conditions 377bt — Clear Rules for All Users

Here you'll find, in plain and straightforward English, the rules governing the use of the 377bt platform — registration, bets, bonuses, Pix withdrawals, casino, and more. Please read carefully before creating your account.

Last updated: January 2026 Brazilian Portuguese Version

What You Need Good to Know to Get Started

The most important points of 377bt's Terms and Conditions, summarized in plain language

Prohibited for Users Under 18

377bt is an adults-only platform. Registration and use of the platform are prohibited for anyone under 18 years of age. Identity verification may be requested at any time.

10x Rollover Bonus

The 100% welcome bonus carries a 10x rollover requirement within 30 days. That means a R$ 100.00 bonus requires R$ 1,000.00 in qualifying bets before you can withdraw. Clear terms, no surprises.

Withdraw via Pix in up to 90 Seconds

Pix withdrawals are processed within 90 seconds of approval, with no fee. The bank account holder must match the name registered on 377bt. Withdrawals to third-party accounts are not permitted.

Security & Identity Verification

377bt may request identity documents (national ID, driver's license, or passport) and proof of address at any time, particularly for larger withdrawals. The process is quick and necessary to ensure everyone's security.

Responsible Gambling Tools

377bt provides deposit limits, temporary and permanent self-exclusion, and specialist support. These tools are encouraged and can be activated at any time by the user from within their account area.

Please read carefully before registering.

By creating an account at 377bt, you confirm that you have read, understood, and agreed to all Terms and Conditions below. These terms constitute a binding agreement between you and 377bt. If you have any questions, please contact our support team before proceeding.

01 Definitions and Parties

For the purposes of these Terms and Conditions, the following definitions apply:

  • "377bt" or "Platform": refers to the sports betting and online casino service available at https://377bt.best and its subdomains, operated by the company responsible for the site.
  • "Username" or "you": an individual, aged 18 or over, residing in Brazil, who registers and uses 377bt's services.
  • "Account": individual profile created by the user upon registration, linked to a unique and valid CPF.
  • "Bet": amount in BRL (R$) placed by the user on a sports outcome or casino game available on the platform.
  • "Bonus": credit granted by 377bt to the user, subject to the specific terms of use and rollover conditions described in the corresponding promotion.
  • "Real Balance": amount in BRL (R$) deposited by the user, available for betting and withdrawal.
  • "Bonus Balance": bonus credit subject to rollover conditions, not withdrawable until all applicable conditions have been met.

These Terms and Conditions govern the entire relationship between 377bt and platform users, including the use of all services, features, promotions, and content made available.

02 Eligibility & Registration Important

To create an account at 377bt, you must meet all of the following requirements:

  • Be at least 18 years of age as of the registration date.
  • Be a Brazilian resident and hold a valid CPF issued by the Receita Federal.
  • Provide accurate, complete, and up-to-date information on the registration form.
  • No active or suspended account at 377bt, whether in your own name or on behalf of a third party.
  • Not be on an active self-exclusion list under any responsible gambling program.

One account per CPF. Each CPF may be linked to only one active account at 377bt. Creating multiple accounts is a serious violation and may result in the permanent suspension of all associated accounts and retention of balances.

By registering, you authorize 377bt to verify your information against public and private databases for identity confirmation, fraud prevention, and regulatory compliance purposes. Full identity verification — including submission of a government-issued ID (RG or CNH) and a selfie — may be required before withdrawals above certain amounts are released.

Registration Responsibility

You are solely responsible for keeping your account credentials — username and password — secure. 377bt will never ask for your password by email, chat, or phone. If you suspect unauthorized access, change your password immediately and contact support.

03 Platform Access

377bt is accessible via web browser (desktop and mobile) at https://377bt.best. No app download required — the platform runs directly in Chrome, Safari, Firefox, or any up-to-date browser.

Access to the platform is provided "as is". 377bt does not guarantee uninterrupted availability and may carry out scheduled or emergency maintenance without prior notice. During periods of unavailability, bets in progress are handled in accordance with the specific rules of each sport or game.

  • 377bt reserves the right to restrict access for users from specific regions or devices without prior notice, in accordance with legal or security requirements.
  • Using a VPN, proxies, or any IP-masking technology to access the platform is a violation of these terms and may result in account suspension.
  • Automating bets via bots, scripts, or third-party software is strictly prohibited.
04 Deposits

377bt accepts the following deposit methods for Brazilian users:

  • Pix: instant transfer via Pix key (CPF, email, phone number, or random key). Immediate processing, 24 hours a day.
  • Boleto Bancário: generated at the time of deposit, with a clearing period of up to 1 business day.
  • Credit or Debit Card: Visa and Mastercard accepted. Subject to issuer approval.
  • PicPay: transfer via PicPay digital wallet. Processing within up to 30 minutes.
  • Mercado Pago: transfer via Mercado Pago wallet. Processed within 30 minutes.

Minimum deposit: R$ 20.00. The maximum deposit per transaction varies depending on the method used. Check the Deposits and Withdrawals section of the platform for current limits.

All deposits must be made using payment methods registered under the account holder's name at 377bt. Third-party deposits are prohibited and may be returned to the original sender. 377bt is not responsible for amounts deposited by mistake or in duplicate — in such cases, contact support immediately.

Processing & Confirmation

Pix deposits are credited automatically once confirmed by the Brazilian banking network. For other methods, processing times may vary. If a deposit has not been credited within the expected timeframe, 377bt support is available 24 hours a day to investigate the transaction upon presentation of proof of payment.

05 Withdrawals Pix in 90s

Withdrawals at 377bt are processed via Pix as the standard method, with processing times of up to 90 seconds after approval. The minimum withdrawal amount is R$ 10.00 and there are no withdrawal fees.

Withdrawal Conditions
  • The bank account holder receiving the withdrawal must match the account registered at 377bt (same CPF).
  • Withdrawals to third-party accounts are strictly prohibited and may result in the request being cancelled and the account being investigated.
  • Before your first withdrawal, full identity verification may be required — submission of a national ID (RG) or driver's license (CNH), front and back, plus a selfie holding the document.
  • Bonus funds may only be withdrawn after the rollover and all other conditions of the applicable promotion have been fully met.
  • Withdrawals above R$ 5,000.00 may require additional documentation in accordance with anti-money laundering (AML) requirements.
Processing time:

Pix withdrawals are processed within 90 seconds under normal conditions. In exceptional circumstances — such as a security review, pending identity verification, or high demand — processing may take up to 48 hours. 377bt will notify the user by email if there is a delay.

06 Sports Betting

377bt offers pre-match and live Sports Betting across more than 30 sports, including football (Brasileirão Série A, Copa do Brasil, Libertadores), UFC and MMA, NBB basketball, volleyball, e-sports, tennis, and more. The following general rules apply to all sports bets:

  • Confirmed bets cannot be canceled by the user, except when the cash out feature is available and active for that specific bet.
  • The minimum bet amount is R$ 1.00. The maximum varies depending on the event, market, and the user's account history.
  • Bets on events that are canceled or postponed by more than 48 hours are considered void and the stake is returned to the real balance.
  • If an event results in a technical no-contest (e.g., No Contest in MMA), the bet is voided and the stake is refunded.
  • Obvious errors in odds — such as odds clearly outside market standards due to a technical fault — may result in the cancellation of affected bets, with full refund of stakes.
Live Betting & Cash Out

Live bets may be subject to brief interruptions for odds updates. Cash out lets you settle a bet before the final result at the value offered by the platform at the time of the request. The cash out value may be lower or higher than the original stake, depending on how the event unfolds. 377bt reserves the right to suspend cash out at certain points during an event without prior notice.

Sports Integrity

377bt monitors suspicious betting patterns and works with sports organizations to combat match-fixing. Accounts displaying suspicious activity may be preventively suspended and investigated. Bets placed through collusion or using privileged information will be voided and the associated funds withheld.

07 Casino & Games

The 377bt casino section includes live blackjack, roulette, baccarat, slots, crash games, and other titles provided by certified suppliers. The following terms apply to the use of casino games:

  • All digital casino games use Random Number Generators (RNG) audited by certified independent companies.
  • The RTP (Return to Player) for each game is available on its respective information page within the platform.
  • Technical failures during a match — such as internet disconnection or server outage — are handled in accordance with the game provider's rules. In general, interrupted rounds are voided and the wagered amount is returned.
  • 377bt is not liable for losses resulting from failures in the user's internet connection.
Blackjack & Live Games

377bt's live tables are operated by licensed providers with certified studios. The specific rules for each blackjack, roulette, or baccarat variant are available before each game begins. If there is a discrepancy between the result shown in the live stream and the result recorded in the system, the system result prevails, except in cases of proven technical error.

08 Bonuses & Promotions Important

377bt offers regular promotions, including a 100% welcome bonus on your first deposit, up to R$ 500.00. The general conditions applicable to all bonuses are:

Welcome Bonus: 100% match on your first deposit, up to R$ 500.00. 10x rollover required within 30 calendar days from the credit date. Only bets with minimum odds of 1.50 count toward the rollover. Casino bets contribute 100% toward the casino bonus rollover.

  • Each user is entitled to one welcome bonus only, linked to the CPF registered on the account.
  • Bonus balance cannot be withdrawn until the rollover requirement has been fully met.
  • Your real-money balance can be withdrawn at any time — withdrawing it before completing the rollover will automatically cancel the bonus.
  • Bets on events with odds below 1.50, or bets on specific markets (such as Asian handicap of -1.5 or greater), may not count toward the rollover — check the specific conditions of each promotion.
  • The bonus expires automatically after 30 calendar days if the rollover has not been fully completed.
  • 377bt reserves the right to modify, suspend, or cancel any promotion with at least 24 hours' notice, except in cases of detected abuse or fraud.
  • Users who employ low-risk betting strategies to complete the rollover (such as covering all outcomes of the same event) may have their bonus cancelled.

The full conditions of each promotion are available on its respective details page within the platform. If you have any questions about rollover or bonus withdrawal conditions, contact support before accepting any promotion.

09 Prohibited Conduct

The following behaviors are strictly prohibited and may result in immediate account suspension, voided bets, and withheld balances:

  • Creating multiple accounts (multi-accounting) using the same CPF, IP address, or device.
  • Use of insider information or access to non-public information to place sports bets.
  • Colluding with other users to manipulate betting outcomes or gain an unfair advantage in promotions.
  • Use of bots, scripts, automated software, or any technology to automate bets or casino plays.
  • Money laundering: using the platform to move funds of illicit origin or for purposes unrelated to betting and entertainment.
  • Use of credit cards or bank accounts belonging to third parties for deposits.
  • Any intentional attempt to exploit technical glitches, odds errors, or platform bugs.
  • Harassment, threats, or abusive language directed at support staff or other users.
  • Submitting false documents or incorrect information during the identity verification process.

377bt continuously monitors account activity for irregular behavior. If a violation is suspected, the account may be preventively suspended while the investigation is underway. The user will be notified by email and will have the opportunity to contest the decision.

10 Account Closure
Account Closure by the User

You may request the closure of your 377bt account at any time, free of charge, by contacting support. Before closing, we recommend withdrawing your full available real-money balance. Any unmet bonus balances are automatically cancelled upon account closure.

Closure by 377bt

377bt reserves the right to close or suspend accounts in the following situations:

  • Breach of any provision of these Terms and Conditions.
  • Suspected fraud, money laundering, or any other illicit activity.
  • Providing false information during registration or identity verification.
  • Self-exclusion request initiated by the user.
  • Extended account inactivity (over 12 months without login or betting activity).

In the event of account closure due to a proven violation, available balances may be withheld by 377bt depending on the severity of the breach. The user will be notified by email with the reasons for the closure and the options available to contest it.

11 Privacy & LGPD

377bt processes all users' personal data in compliance with Brazil's General Data Protection Law (LGPD — Law No. 13.709/2018). The information collected at registration — such as full name, CPF, email address, date of birth, and payment details — is used exclusively for:

  • Account management and delivery of contracted services.
  • Identity verification and fraud prevention.
  • Communications about bets, promotions, and platform updates (with opt-out option).
  • Compliance with legal and regulatory obligations.

377bt does not sell, rent, or share personal data with third parties without explicit consent, except as required by law or a competent authority. All communications are protected by 256-bit SSL encryption. To exercise your rights as a data subject (access, correction, portability, or deletion), contact us at suporte@377bt.best.

For detailed information on how your data is handled, visit our Privacy Policy.

12 Responsible Gambling

377bt believes betting should be a form of entertainment, not a source of problems. That's why we offer the following responsible gambling tools, accessible directly from your account area:

  • Deposit limits: set a maximum daily, weekly, or monthly deposit limit. Once set, the limit can only be increased after a 7-day cooling-off period.
  • Betting limit: set a cap on the maximum amount wagered per period.
  • Temporary self-exclusion: suspend your account for periods of 1 week, 1 month, 3 months, or 6 months. During self-exclusion, creating a new account or logging in is not permitted.
  • Permanent self-exclusion: permanent account closure with no possibility of reactivation.
  • Real-time: alerts on active session time on the platform.

If you or someone you know is struggling with gambling, contact 377bt's support team or visit our Responsible Gambling for information on support resources available in Brazil. The platform is strictly prohibited for users under 18 — reports of underage access are treated as the highest priority.

13 Limitation of Liability

377bt is not liable for financial losses resulting from:

  • Betting or casino game outcomes, which are inherently uncertain.
  • Internet connection failures or issues with the user's device during bets or gaming sessions.
  • Service interruptions due to scheduled or emergency maintenance.
  • Third-party actions, such as external banking fraud outside the platform.
  • Decisions based on incorrect information provided by the user during registration.

377bt's total liability to any individual user, under any circumstances, is limited to the real balance available in the user's account at the time of the event giving rise to the claim. 377bt is not liable for indirect damages, lost profits, or consequential losses of any kind.

14 Changes to These Terms

377bt reserves the right to update these Terms and Conditions at any time. Significant changes will be communicated to users by email with at least 7 days' notice. Minor changes — such as text corrections or clarifications — may be implemented without prior notice.

The most recent version of the Terms and Conditions will always be available on this page, with the date of the last update shown at the top of the document. Continued use of the platform after the effective date of the updated conditions constitutes tacit acceptance of the changes. If you do not agree with the new terms, you may close your account without penalty before the effective date.

15 Jurisdiction and Applicable Law

These Terms and Conditions are governed by the laws of the Federative Republic of Brazil. Any dispute arising from the use of 377bt that cannot be resolved amicably through customer support will be referred to mediation or, if unsuccessful, to the courts of the District of São Paulo — SP, with express waiver of any other jurisdiction, however privileged.

377bt is committed to responding to all user complaints within 5 business days through the available support channels. For urgent matters related to withdrawals or account security, the response time is up to 24 hours.
