Before creating your account or placing any bet on bet4k, please read the terms below carefully. They explain your rights, our responsibilities, and the rules governing use of the platform. We've written everything in plain language, without unnecessary legal jargon.
We've summarized the most important points of our terms so you have a clear picture before you start using the bet4k platform.
Each user may hold only one active account on bet4k. Registration requires a valid CPF, a Brazilian email address, and a Brazilian mobile number. Identity verification is mandatory before the first withdrawal. Duplicate accounts are closed and balances retained in accordance with the terms.
All transactions on bet4k are processed exclusively in BRL (R$). Minimum deposit of R$ 20.00 via Pix, bank slip, credit or debit card, PicPay, or Mercado Pago. Withdrawals via Pix in up to 5 minutes, no fees, minimum of R$ 20.00.
Every bonus offered by bet4k has rollover requirements clearly published prior to activation. The standard minimum rollover for the welcome bonus is 30x the bonus amount. Specific details for each promotion are described on the corresponding page.
Your personal data is protected in full compliance with Brazil's General Data Protection Law (Law No. 13,709/2018). 256-bit SSL encryption is applied to all sessions. Two-factor authentication is available. No data is sold or shared without your consent.
Bet4k is a platform exclusively for users aged 18 and over. Registration by minors is prohibited by law and by our internal policies. If an irregularity is identified, the account is immediately suspended and the balance returned upon verification of ownership.
Bet4k offers deposit limits, betting limits, and self-exclusion tools to all users. These tools are voluntary and take effect immediately upon activation. Limit increases have a 7-day waiting period for added security.
By creating an account, making a deposit, or using any service provided by bet4k, you confirm that you have read, understood, and agreed to all terms and conditions described on this page. If you disagree with any point, please do not use the platform.
These Terms and Conditions constitute a legal agreement between you ("User") and bet4k ("Platform", "we"). By accessing the site, creating an account, or using any feature offered by bet4k — including Sports Betting, live casino, crash games, slots, and roulette — you confirm that you have read and fully accept these terms.
Acceptance is automatic upon completing the registration process. If you do not agree with any provision contained herein, please stop using the platform and contact our support team for clarification or to request account closure.
Bet4k reserves the right to update these Terms at any time. Material changes will be communicated via the registered email address and/or through a prominent notice on the platform at least 7 days in advance. Continued use of the platform after such notice constitutes acceptance of the changes.
Current version: January 2026. Whenever you log in after an update, you will be notified of the relevant changes to the terms.
To create an account on bet4k and use its services, you must meet all of the following requirements:
Registering on bet4k requires accurate and truthful information: full legal name as it appears on an official document, CPF, date of birth, active email address, and a Brazilian mobile number. Providing false information constitutes an immediate violation of these terms and may result in account closure and the withholding of any balances pending verification.
Before the first withdrawal is released, all users go through an identity verification process (KYC — Know Your Customer). We require a copy of an official government-issued photo ID (national ID card, driver's license, or passport) and proof of address issued within the last 90 days. The process is carried out by our in-house team within 48 business hours.
Each user may hold only one active account on bet4k. Creating multiple accounts to claim bonuses improperly or for any other reason is strictly prohibited and constitutes fraud against the platform. Any duplicate accounts identified will have their balances consolidated into the original account, and the duplicates will be closed immediately.
Bet4k uses real-time CPF verification technology integrated with Brazil's Receita Federal systems. Invalid or cancelled CPFs, and those belonging to users under 18, are automatically blocked during registration.
All transactions on bet4k are processed exclusively in BRL (R$). The platform does not accept or convert foreign currencies under any circumstances.
Bet4k accepts the following deposit methods for Brazilian users:
The minimum deposit is R$ 20.00 per transaction. There is no maximum deposit limit, subject to confirmation for amounts above R$ 10,000.00 for compliance purposes.
Bet4k processes withdrawals exclusively via Pix to the registered and verified Pix key in the account holder's name. The minimum withdrawal is R$ 20.00. There are no withdrawal fees. Processing time is up to 5 minutes after the request, available 24 hours a day, 7 days a week, including weekends and holidays.
For withdrawals above R$ 5,000.00, bet4k may request additional documentation for compliance and anti-money laundering purposes, in accordance with applicable regulations. The review period in such cases is up to 2 business days.
Bonus balances may only be withdrawn after the wagering requirements have been fully met. Withdrawing a bonus balance before completing the rollover will result in the forfeiture of the remaining bonus amount; only the accumulated real balance will be retained.
Bet4k offers Sports Betting on football (Brasileirão Série A and B, Copa do Brasil, Libertadores, Copa Sudamericana, and state championships), volleyball (men's and women's Superliga, Nations League), basketball (NBB), MMA/UFC, tennis, e-sports, and more. The casino features live roulette, slots, crash games, and blackjack.
Bet4k employs advanced fraud detection systems. The following behaviors are strictly prohibited and subject to immediate account closure and balance retention:
All casino games available on bet4k — including European roulette, Lightning Roulette, slots, crash games such as Aviator, and blackjack — use certified random number generators (RNG) or supervised live streams. The RTP (return to player) for each game is published on that game's page. Game results are final and cannot be disputed once a round is complete.
Bet4k offers bonuses and promotions on a regular basis, including a welcome bonus, weekly cashback, free bets, and seasonal promotions. Each promotion has specific terms published on its details page — those terms complement and take precedence over the general provisions of this section in the event of any conflict.
Bet4k's standard welcome bonus matches 100% of your first deposit, up to a maximum of R$ 500.00. To activate the bonus, the minimum qualifying deposit is R$ 20.00. The bonus is automatically credited to your account once the deposit is confirmed.
The welcome bonus carries a 30x rollover requirement on the bonus amount for Sports Betting with minimum odds of 1.50, or the equivalent in casino games. The rollover must be completed within 30 calendar days from the date the bonus is credited. Any unused bonus balance remaining after this deadline will be automatically canceled.
The 10% weekly cashback is calculated based on the net balance lost from Monday through Sunday of each week. The amount is credited every second Saturday after the period ends, with no request needed. Weekly cashback is not subject to any rollover and can be withdrawn immediately after it is credited.
At bet4k, we believe betting is a form of entertainment — and all entertainment works best within healthy boundaries. That's why we offer a full set of responsible gambling tools that any user can activate at any time from their account dashboard.
