Terms and Conditions a18bet: Platform Usage Rules

These Terms and Conditions govern the use of all services offered by a18bet in Brazil — registration, deposits, withdrawals, Sports Betting, Live Casino, slots, bonuses, and the VIP Program. Please read carefully before using the platform.

Last updated: July 1, 2026

Welcome to a18bet. Before using any feature on the platform — whether betting on the Brasileirão, playing at the Live Casino, spinning a jackpot slot, or joining the VIP Program — you must read and understand these Terms and Conditions. They form a legal contract between you and the a18bet, and by creating an account or using the platform, you agree to everything set out here.

The a18bet made every effort to write these terms in plain, straightforward language, free of unnecessary legal jargon. If you have any questions about any point, please reach out to our Portuguese-language support via the platform chat or by email at suporte@a18bet.best before continuing.

1 Definitions and Acceptance of Terms

For the purposes of these Terms and Conditions, the following terms have the meanings set out below:

  • "a18bet" refers to the Sports Betting and online casino platform operated under the domain a18bet.best, including all its services, products, and features available to users in Brazil.
  • "User" is any individual with a registered and active account on the a18bet, residing in Brazil and aged 18 or older.
  • "Account" is the individual profile created by the User upon completing and verifying the registration process on the platform.
  • "Balance" refers to the total funds available in the User's account, including deposited real balance and bonus balance, where applicable.
  • "Bonus" are promotional credits granted by a18bet to the User in accordance with current promotions, subject to specific terms of use.
  • "Services" cover live and pre-match Sports Betting, Live Casino, slots, progressive jackpots, crash games, roulette, the VIP Program, and all other platform features.

By creating an account, making a deposit, using any of the Services, or simply browsing the platform of a18bet, you confirm that you have read, understood, and fully accepted these Terms and Conditions, as well as our Privacy Policy and the rules of Responsible Gambling. If you do not agree with any part of these terms, you should not use the platform.

2 Eligibility and Registration

To create an account and use the Services of a18bet, the User must:

  • Be at least 18 years old — the a18bet does not provide services to minors under any circumstances.
  • Be a Brazilian resident with a valid CPF registered with the Receita Federal.
  • Not be included on any gambling self-exclusion list in Brazil.
  • Not holding any other active account on the platform — each User is entitled to only an account on a18bet.
  • Provide accurate, complete, and up-to-date information at the time of registration.

Identity Verification (KYC)

The a18bet reserves the right to request proof of identity and residence documents at any time. The verification process (KYC — Know Your Customer) is mandatory before withdrawals above certain amounts and may include: a government-issued photo ID (RG or CNH), CPF, proof of address, and a selfie with your document. Unverified accounts may have withdrawals suspended until the process is complete.

Important

Creating multiple accounts using the same CPF, email address, or banking information constitutes a violation of these Terms and will result in the immediate blocking of all accounts involved and the cancellation of any bonus balances.

3 Deposits & Payment Methods

The a18bet accepts the following deposit methods available to users in Brazil:

  • Pix — the primary method, with instant credit 24 hours a day, including weekends and national public holidays.
  • Boleto bancário — settlement within 1 to 3 business days after payment.
  • Credit and debit card — major card brands accepted, subject to approval by the card issuer.
  • TED bank transfer — via Nubank, Itaú, Bradesco, Banco do Brasil, Caixa Econômica Federal, and other institutions authorized by the Brazilian Central Bank.
  • PicPay and Mercado Pago — subject to availability and limits of the respective platforms.

The minimum deposit amount is R$ 20.00. The a18bet does not charge fees on deposits; however, the User's financial institution may apply its own charges. All deposits must be made from accounts held in the registered User's name — third-party deposits are not accepted and will be reversed.

The a18bet uses payment processing systems with 256-bit SSL encryption. No card data is stored directly on our servers — processing is handled by PCI-DSS certified intermediaries.

4 Withdrawals

To request a withdrawal at the a18bet, the User must have a verified account (KYC completed) and the available real balance must be equal to or greater than the minimum withdrawal amount of R$ 30.00. Withdrawals must be made to the same payment method used for the deposit — except in cases authorized by support.

Processing times

  • Pix: withdrawals processed in up to 5 minutes after approval, 24 hours a day, 7 days a week.
  • TED transfer: processed on business days, within standard Brazilian banking hours.
  • Boleto bancário: not available for withdrawals — deposits only.
  • Credit card: card reversals may take 5 to 10 business days depending on the card issuer.

The a18bet does not charge fees on Pix withdrawals. The amount requested is the amount credited to the User's account. For withdrawals above R$ 10,000.00, additional documentation may be required in accordance with compliance and anti-money laundering regulations (Law No. 9.613/1998).

VIP Members

Users at the Gold, Platinum, and Diamond tiers of the VIP Program receive priority withdrawal processing — most Pix withdrawals are approved in under 2 minutes. Diamond members have no weekly withdrawal limit.

5 Bonuses and Promotions

The a18bet offers bonuses and periodic promotions, including a 200% welcome bonus on the first deposit, capped at R$ 500.00 in bonus funds. Each promotion has its own specific terms — the rollover, validity period, and eligible markets are defined individually for each offer and communicated at the time the bonus is granted.

  • Each User is entitled to one welcome bonus only, linked to the registered CPF.
  • Bonuses are non-transferable between accounts and may not be withdrawn before the applicable rollover conditions have been met.
  • Bonus balance is used only after real balance is exhausted on bets, unless the specific promotion states otherwise.
  • Voided, canceled, or bets placed at odds below the minimum threshold may not count toward the bonus rollover.
  • The a18bet reserves the right to cancel bonuses upon detection of abusive use, multiple account creation, or bets that constitute arbitrage.
  • The weekly VIP Program cashback is credited as available balance, subject to the specific conditions described in section 8 of these Terms.

Bonus promotions are valid for Sports Betting (Brasileirão, Libertadores, Copa do Brasil, and other competitions) and casino games, as specified in each offer. The a18bet may modify, suspend, or end any promotion at any time, with prior notice through the appropriate communication channel.

6 Sports Betting

Sports bets placed on a18bet follow these general rules:

  • Odds are displayed in decimal format and may change at any time before the bet is confirmed.
  • A bet is considered valid only after confirmation with the bet receipt generated by the system.
  • Live bets are subject to broadcast delays — the a18bet is not responsible for discrepancies between the actual game state and what is displayed on the platform at the time of the bet.
  • Cash Out (early settlement) is available on selected bets and subject to market availability. The Cash Out value is determined by the system in real time.
  • If an event is canceled, the bet is voided and the amount is returned to the User's balance.
  • For parlay bets, the cancellation of one selection results in the ticket being recalculated with the remaining selections.

Markets & Coverage

The a18bet covers all 380 matches of the Brasileirão Série A, Copa do Brasil, Copa Libertadores, Brazilian state championships, and the major international tournaments. Markets for volleyball, basketball (NBB), MMA/UFC, tennis, and e-sports are also available. The number of markets per event varies depending on the competition and the level of live broadcast coverage.

The a18bet reserves the right to limit bets, adjust odds, or cancel bets in cases of detected irregularities, obvious pricing errors, or violations of the rules set out in this section.

7 Live Casino, Slots, and Other Games

The casino games available on a18bet — including live tables for blackjack, baccarat, roulette, and poker, slots with and without progressive jackpots, crash games, and other titles — are provided by software providers certified by independent auditing laboratories. All results are generated by certified RNG (Random Number Generator) systems, ensuring randomness and fairness.

  • The RTP (Return to Player) for each game is displayed on the title's panel before the session begins.
  • Technical failures during a game session will be investigated by a18bet based on server records — in the event of a disconnection, the round state is recovered from the server logs.
  • Bets placed with bonus balance on casino games may have a different contribution rate toward the rollover — please refer to the specific bonus terms.
  • Progressive jackpots are funded by a fraction of every bet placed on the game and are paid out according to the provider's rules. The minimum eligible bet amount to participate in the progressive jackpot is shown on each slot's panel.

The a18bet is not liable for service interruptions caused by scheduled maintenance or infrastructure failures on the part of game providers. In all cases, bets in progress are settled according to server records at the time of the interruption.

8 VIP Program

The VIP Program of the a18bet consists of five tiers — Bronze, Silver, Gold, Platinum, and Diamond — with progression criteria based on monthly real-money betting volume. Enrollment is automatic for all Users with an active account.

  • VIP tier is reassessed monthly based on betting volume over the previous 30 days.
  • The weekly cashback is calculated on net losses for the period and credited every Friday as available balance.
  • Different game types may contribute differently to VIP volume — bets placed with bonus balance have reduced or zero contribution, as specified in the bonus terms.
  • Benefits such as a dedicated account manager (Platinum and Diamond), exclusive tables (Gold and above), and higher limits take effect immediately upon tier promotion.
  • The a18bet reserves the right to modify the criteria, benefits, and tier structure of the VIP Program with 15 days' prior notice to affected Users.

9 User Conduct and Prohibited Activities

The User agrees to use the platform of a18bet exclusively for personal entertainment purposes, on an individual and non-commercial basis. The following are strictly prohibited:

  • Creating or operating bots, scripts, or automated systems to place bets, collect data, or abuse promotions.
  • Placing bets with the intent to arbitrage odds across platforms or systematically exploit pricing errors.
  • Using insider information, match-fixing, or any form of sports fraud to gain an advantage in betting.
  • Attempting to launder money or using the platform for any illicit financial activity under Brazilian law.
  • Sharing login credentials or using another User's account.
  • Creating multiple accounts with the same CPF, device, or IP address to abuse welcome bonuses or promotions.
  • Making threats, harassing others, or using abusive language on any communication channel of the a18bet.

Detection of any prohibited behavior will trigger an investigation and may result in immediate account suspension, cancellation of bonus balances, and, in serious cases, reporting to the relevant Brazilian authorities.

10 Account Suspension and Closure

The a18bet may suspend or close a User's account in the following situations:

  • Violation of any provision of these Terms and Conditions.
  • Self-exclusion request by the User.
  • Detection of underage use.
  • Accounts inactive for more than 12 months, following email notification.
  • Legal or regulatory determination by the competent Brazilian authorities.

Users may also close their account at any time by contacting support. Upon closure, any available real balance will be returned after identity verification and standard withdrawal processing. Unused bonus balances are forfeited at the time of closure.

The a18bet may unilaterally close accounts suspected of fraud without prior notice, retaining funds until the investigation is complete.

11 Limitation of Liability

The a18bet offers its platform "as is", with reasonable efforts toward availability and security. The a18bet is not liable for:

  • Financial losses resulting from sports bets or casino games played on the platform — sports betting and gambling carry inherent financial risk.
  • Service interruptions caused by third-party infrastructure failures, cyberattacks, scheduled maintenance, or events beyond the platform's control.
  • Misinterpretation of betting rules by the User.
  • Loss of account access due to a forgotten password or credentials compromised by the User.
  • Indirect, special, or consequential damages arising from the use of the platform.

The maximum liability of a18bet toward any User, under any circumstances, is limited to the real balance available in the User's account at the time the event giving rise to the claim occurs.

12 Responsible Gambling

The a18bet believes that betting should be a form of entertainment, never a source of income or a solution to financial problems. The platform offers the following responsible gambling tools:

  • Daily/weekly/monthly deposit limit: the User may set maximum deposit limits in the account settings area.
  • Session loss limit: lets you set a maximum loss amount before an automatic pause is triggered.
  • Temporary self-exclusion: the User may self-exclude from the platform for periods of 7, 30, 90, or 180 days.
  • Permanent self-exclusion: permanent account closure with a CPF-level block.
  • Game reality: session time and betting volume notifications to help you stay in control.

The a18bet blocks access for self-excluded users and does not accept registrations from anyone under 18. If you or someone you know shows signs of problem gambling, visit our Responsible Gambling for help resources in Brazil.

13 Privacy and Data Protection (LGPD)

The processing of Users' personal data by a18bet is carried out in compliance with Brazil's General Data Protection Law (LGPD — Law No. 13,709/2018). Data collected during registration and platform use is used exclusively for:

  • Identity verification and fraud prevention.
  • Deposit and withdrawal processing.
  • Operation of the Services and the VIP Program.
  • Communication of promotions and news from a18bet (with opt-out option).
  • Compliance with Brazilian legal and regulatory obligations.

Your data is never sold, rented, or shared with third parties for commercial purposes. Sharing with partners occurs solely for payment processing and game providers, under contractual confidentiality obligations. Users have the right to access, correct, port, or request deletion of their data by contacting support. See our Privacy Policy for full details on how personal data is handled.

14 Changes to Terms and Conditions

The a18bet reserves the right to modify these Terms and Conditions at any time. Material changes will be communicated to Users at least 15 days in advance through:

  • Visible notification on the platform at login.
  • Email sent to the address registered on the account.
  • Update of the "last modified" date at the top of this page.

Continued use of the platform after the effective date of any changes constitutes acceptance of the updated Terms. If you do not agree with the changes, you must close your account and request a withdrawal of your available balance before the new terms take effect.

15 Final Provisions

These Terms and Conditions are governed by the laws of the Federative Republic of Brazil. Any disputes between the User and a18bet that cannot be resolved amicably will be submitted to the jurisdiction of the Comarca de São Paulo, State of São Paulo, with express waiver of any other jurisdiction, however privileged it may be.

If any provision of these Terms is found invalid or unenforceable by a competent authority, the remaining provisions will remain in full force and effect. The failure of a18bet in exercising any right provided under these Terms shall not constitute a waiver of that right.

For questions, complaints, or requests related to these Terms, contact the support team at a18bet via the platform's chat (available 24 hours in Portuguese) or by email suporte@a18bet.best. Platinum and Diamond level members can contact their account manager directly via WhatsApp.

These Terms and Conditions take effect on July 1, 2026, and supersede all previous versions. To access prior versions, please contact support.

❓ Questions about the Terms and Conditions

The most frequently asked questions from users about a18bet's rules

Yes, for withdrawals above certain amounts a18bet requires identity verification (KYC). The process is completed once and typically includes a government-issued photo ID (RG or CNH), CPF, and proof of address. For most users, verification takes less than 24 hours after the correct documents are submitted. Pix withdrawals of smaller amounts may be approved without full KYC, but we recommend verifying your account in advance to avoid any future delays.

Any real balance remaining in the account is returned to the User via the payment method used for deposits, once identity verification is complete. The return follows standard withdrawal timelines — via Pix in up to 5 minutes after approval. Unused bonus balances are automatically cancelled when the account is closed and are not refunded. If you are considering closing your account for responsible gambling reasons, we recommend first using the temporary self-exclusion tool available in your account settings.

No. a18bet requires that all deposits and withdrawals be made through bank accounts held in the name of the platform account holder. Deposits made by third parties are identified and automatically reversed to the sender. This policy exists to protect Users against fraud and to comply with Brazilian anti-money laundering regulations. If you only have access to a joint account, contact support to find the best solution before completing the transaction.

The 200% welcome bonus up to R$ 500.00 has rollover requirements that are disclosed at the time the bonus is granted. Generally, the bonus amount must be wagered a set number of times before it can be withdrawn — bets on markets with odds above a minimum threshold count in full, while bets at very low odds or voided bets may have reduced or zero contribution. Sports bets on the Brasileirão, Copa do Brasil, and Libertadores at standard odds count in full. Check the specific bonus Terms in the promotions section of your account for the exact rollover details currently in effect.

Under normal circumstances, bets confirmed with a system-generated receipt are not cancelled by a18bet. Cases where this may occur include: an obvious pricing error (odds that are clearly incorrect and do not reflect actual market conditions), cancellation of the sporting event before it begins (in which case the amount is refunded to the balance), and detection of an irregularity in the sporting result as recognized by the organizing body. In all cases, a18bet notifies the User by email and credits the corresponding amount to the account balance within 24 hours.
