2. Registration & Eligibility
To create an account at wi888 and use the services offered, you must meet all of the following criteria:

Registration is free and completed entirely online, with no in-person visit required. You will be asked to provide: full name, CPF, date of birth, a valid email address, mobile number, and, where applicable, identification documents for identity verification (KYC).
3. User Account
Once your registration is approved, you will hold a personal, non-transferable account at wi888. You are solely responsible for:
- Keep your login credentials (email and password) confidential;
- All activities carried out through your account, including deposits, bets, and withdrawals;
- Ensure your registration details are always up to date and accurate;
- Notify wi888 immediately in the event of unauthorized access, loss, or suspected compromise of your account.
Wi888 is not liable for losses arising from unauthorized use of your account resulting from your own negligence in protecting your login credentials. We recommend using a strong, unique password and enabling two-factor authentication where available.
Identity verification (KYC): wi888 may request identity verification documents (government-issued ID, driver's license, proof of address) at any time, especially before processing withdrawals above certain amounts. Failure to provide the required documents within the established timeframe may result in a temporary hold on your withdrawal balance.
4. Deposits
All deposits at wi888 are processed in BRL (R$). The platform accepts the following payment methods:
- Pix — instant credit, available 24 hours a day, 7 days a week, including holidays;
- Credit and debit card — Visa, Mastercard, Elo, Hipercard;
- Bank slip (Boleto) — settlement within 1 (one) business day after payment;
- Mercado Pago — fast processing with no additional fees for the player;
- PicPay — mobile processing;
- TED Transfer — Nubank, Itaú, Bradesco, Banco do Brasil, and other Brazilian financial institutions.
The minimum deposit is R$ 20.00 (twenty BRL). There is no default maximum deposit limit, though wi888 may set individual limits based on account review. The amount credited to the account is exactly the amount deposited, with no discounts or fees charged to the player.
Important: wi888 only accepts deposits made from bank accounts or payment instruments registered in the account holder's own name. Third-party deposits are not accepted and will be returned after deduction of any applicable banking fees.
5. Withdrawals
You can request a withdrawal of the available balance in your account wi888 at any time, subject to the following conditions:
- The minimum withdrawal amount is R$ 30.00 (thirty BRL);
- The withdrawal method must be registered under the same CPF as the account holder;
- Pix withdrawals are processed within 5 (five) minutes of approval, 24 hours a day, 7 days a week;
- Withdrawals via other methods may take up to 3 (three) business days to process;
- Wi888 may require identity verification before processing withdrawals, particularly for first-time requests or higher-value withdrawals;
- Balances originating from bonuses may only be withdrawn after the corresponding rollover requirement has been fully met.
The balance available for withdrawal consists solely of your real account balance — that is, directly deposited funds and winnings from bets placed with real-money balance. Bonus balance cannot be withdrawn until the rollover is completed.
Withdrawal limits: wi888 may set daily, weekly, or monthly withdrawal limits in accordance with the platform's risk management policy. Players at higher tiers of the VIP loyalty program may have differentiated limits. Details on individual limits can be found in the account dashboard or by contacting support.
6. Bonuses & Promotions
A wi888 offers bonuses and promotions on a regular basis, including a welcome bonus, weekly cashback, free spins, poker freerolls, and slots tournaments. All promotions are subject to the following general conditions:
- Each bonus may be redeemed only once per account holder, unless explicitly stated otherwise;
- The welcome bonus is exclusive to new registrations and valid on the first deposit only;
- The standard rollover requirement for the welcome bonus is 30x (thirty times) the bonus amount received;
- The deadline to complete the rollover is 30 (thirty) days from the moment the bonus is activated;
- The rollover is calculated on the bonus amount, not on the combined total of deposit plus bonus;
- Different game types may contribute differently to the rollover — slots contribute 100%, while some Live Casino categories may have a reduced contribution;
- Wi888 reserves the right to cancel bonuses if abuse is suspected, including the use of multiple accounts, betting on both sides of an event, or any strategy that constitutes improper exploitation of promotions.
Specific promotions may have additional terms published on the offer page. In the event of a conflict between the general terms and the specific terms of a promotion, the specific terms shall prevail.
7. Sports Betting
Wi888 offers betting on football (Brasileirão Série A and B, Copa do Brasil, Libertadores, Sul-Americana, state championships, and European leagues), volleyball, basketball (NBB), MMA/UFC, e-sports, and more. The general rules applicable to all sports bets are:
- A confirmed bet cannot be cancelled by the player, except where the Cash Out feature is available and used within the applicable timeframe;
- The odds displayed at the time the bet is confirmed are the valid odds for that ticket, even if they change afterward;
- If a match is cancelled or postponed by more than 24 hours from its original date, single bets on that event will be voided and the staked amount refunded in full. For combination bets, the cancelled event is removed from the slip and the odds recalculated;
- In the event of a manifest error in the odds (odds that are clearly incorrect due to a technical or human mistake), wi888 reserves the right to void any bets placed on those odds and refund the staked amounts;
- Matches ended early due to force majeure will be settled according to each competition's rules — in general, results officially ratified by the organizing body will be considered valid;
- The minimum bet amount per selection is R$ 1.00 (one BRL).
Live betting: In live betting, odds are updated in real time and may be temporarily suspended during key moments in a match (goals, cards, corners). Bets placed during odds suspension periods may be voided. Cash Out is available on most live bets and allows you to close a bet early at the value calculated at the time of the request.
8. Casino & Games
The casino section of wi888 includes slots, live casino, poker, crash games such as Aviator and JetX, and other digital entertainment formats. The following rules apply:
- All casino games use a certified Random Number Generator (RNG) audited by an independent body, ensuring random and unbiased results;
- The RTP (Return to Player) of each game is set by its respective provider and can be found in the game's information section. Individual results may vary significantly from the theoretical RTP;
- In the event of a technical failure during a game session (connection drop, server error, etc.), affected bets will be handled according to the system logs. Rounds not completed due to a technical failure will be voided and the staked amount refunded;
- The live casino is streamed in real time by licensed providers such as Evolution Gaming and Pragmatic Live. Any stream interruptions are subject to each provider's specific rules;
- Wi888 is not liable for losses resulting from the player's internet connection being disrupted during an active session.
9. Prohibited Conduct
Users of wi888:
- Creating more than one account on the platform (duplicate accounts by CPF, email, device, or IP);
- Providing false, incomplete, or third-party information during registration or identity verification;
- Using the platform for money laundering, financing illegal activities, or any act contrary to Brazilian law;
- Exploiting platform vulnerabilities, bugs, or technical errors for personal gain — any identified issue must be reported to support immediately;
- Using automation software, bots, scripts, or any technology to place bets or interact with the platform in a non-human manner;
- Placing bets on both sides of the same event across different accounts to guarantee profit regardless of the outcome;
- Placing bets with the sole purpose of meeting bonus rollover requirements by systematically using low-risk markets in a way that constitutes promotional abuse;
- Sharing your login credentials with third parties or allowing another person to use your account.
Any identified prohibited conduct may result in immediate account closure, blocking of pending withdrawals, cancellation of bonuses, and reporting to the relevant authorities where applicable.
10. Account Closure
Account closure at wi888 may be initiated by either the player or the platform:
At the player's request:
- You may request voluntary account closure at any time by contacting customer support;
- Before closure, any pending withdrawals will be processed normally, provided there are no active restrictions on the account;
- Bonus balances that have not met the rollover requirement will be forfeited upon voluntary account closure;
- Accounts closed due to self-exclusion cannot be reopened during the requested exclusion period.
At wi888's discretion:
- Wi888 reserves the right to terminate or suspend accounts that violate these Terms, without prior notice;
- In the event of account closure due to a terms violation, balances linked to irregular activity may be frozen while the matter is under investigation;
- Real-money balances of lawful origin will be returned to the account holder upon completion of the investigation, provided no evidence of fraudulent activity is found.
11. Responsible Gambling
A wi888 is committed to promoting responsible gambling. We believe betting should be a form of entertainment — not an activity that causes financial or personal harm. The platform offers the following self-management tools:
- Deposit limits: Set daily, weekly, or monthly deposit limits directly from your account dashboard;
- Temporary break: Request a 24-hour, 7-day, or 30-day break from account access;
- Self-Exclusion: Request permanent account closure. The request is processed immediately and is irreversible for the requested period;
- Activity history: Access the full record of deposits, withdrawals, and bets placed on the platform.
If you believe gambling is causing problems in your life or in the lives of those close to you, contact wi888 support to activate the self-exclusion tools. You can also seek outside help — GAMBCARE Brasil offers free assistance to people with gambling-related issues.

In summary, your personal data collected by wi888:
- Used exclusively for account management, transaction processing, identity verification, and service-related communications;

13. Limitation of Liability
A wi888 makes every effort to ensure continuous availability and smooth operation of the platform. However, we cannot guarantee uninterrupted service and are not liable for:
- Temporary service interruptions due to scheduled maintenance or unforeseen technical failures;
- Losses resulting from the user's own internet connection failure during gaming or betting sessions;
- Indirect damages, loss of profits, or damages of any nature exceeding the value of the player's available account balance at the time of the event that caused the loss;
