Section 01

Acceptance of Terms

These Terms and Conditions ("Terms") constitute a legal agreement between you ("User") and the 31win ("Platform"), governing access to and use of all services available at 31win.click, including Sports Betting, online casino, poker, and any other products that may be added in the future.

By accessing the site, creating an account, making a deposit, or placing a bet, you expressly confirm that you have read these Terms in full, understood them, and agree to comply with them. This acceptance is mandatory to use any feature of the 31win.

Important: These Terms are written in Brazilian Portuguese and governed by Brazilian law. In the event of any conflict between versions in other languages, the Brazilian Portuguese text shall prevail.

The 31win reserves the right to update these Terms periodically. Significant changes will be communicated with reasonable advance notice by email or via a platform announcement. Continued use of the services after such notice constitutes acceptance of the updated terms.

Section 02

Eligibility and Registration

To create an account at 31win and use its services, the User must meet the following mandatory requirements:

  • Be at least 18 years of age on the date of registration.
  • Be a resident of Brazil or have legal authorization to use online betting services in the country.
  • Hold a valid CPF registered and in good standing with the Receita Federal do Brasil.
  • Not be barred by any court or administrative order, or by an active self-exclusion on any platform in the industry.
  • Not be an employee, service provider, or direct family member of a collaborator of the 31win.

Each User may hold only an active account on the platform. Creating multiple accounts is strictly prohibited and will result in the immediate cancellation of all balances and pending bets, with no right to a refund.

During registration, the User must provide accurate, complete, and up-to-date information. False or outdated information may result in account suspension and withdrawal holds until the situation is resolved. The 31win is not responsible for issues arising from incorrect information provided by the User.

Keep in mind: Signing up with 31win is free, takes less than 2 minutes, and only requires an email address, CPF, and password. We charge no fees to create or maintain an active account.
Section 03

Identity Verification (KYC)

The 31win follows Know Your Customer (KYC) procedures in compliance with anti-money laundering practices and user protection standards. Identity verification may be requested at any time, but is mandatory before the first withdrawal.

Documents that may be requested include:

  • Government-issued photo ID (national ID card, driver's license, or valid passport).
  • Proof of address dated within the last 3 months.
  • Proof of ownership of the Pix key or bank account used for transactions.
  • Selfie with ID document, when required by the risk analysis system.

Document review takes up to 48 business hours after full submission. During this period, withdrawals are on hold, but the User may continue using their available balance for sports betting and casino games. The 31win does not charge any fee for the verification process.

Withdrawals to third-party accounts are not permitted. The withdrawal method must belong to the same account holder registered with 31win. Any attempt to withdraw to a third-party account will result in the amount being held for review.
Section 04

Deposits & Withdrawals

The 31win accepts exclusively Brazilian payment methods. Accepted options include: Pix, boleto bancário, credit or debit card, PicPay, Mercado Pago, and TED bank transfers from banks such as Nubank, Itaú, Bradesco, and Banco do Brasil.

Deposits:

  • Minimum amount: R$ 20.00 per transaction.
  • Pix deposits are credited within seconds, at any time of day.
  • Deposits via boleto bancário may take up to 1 business day to clear.
  • Credit card transactions may be subject to additional review by the card issuer.
  • No fee is charged by the 31win on deposits — any third-party banking fees are the User's responsibility.

Withdrawals:

  • Minimum withdrawal amount: R$ 30.00.
  • Pix withdrawals are processed within 15 minutes, including weekends and public holidays.
  • The 31win does not charge a fee on withdrawals. Any banking fees are the responsibility of the receiving bank.
  • Withdrawals must be made to the same deposit method whenever possible, as an anti-fraud security measure.
  • Balances derived from bonuses are subject to rollover requirements before they can be withdrawn (see Section 08).
Tip: Use Pix for the fastest experience on both deposits and withdrawals. On average, Pix withdrawals at 31win are processed in under 8 minutes.
Section 05

Sports Betting

Sports Betting at 31win cover more than 30 sports, with highlights including football (Brasileirão Série A, Copa do Brasil, Libertadores, Série B, and international competitions), basketball (NBB and NBA), volleyball, MMA/UFC, and e-sports.

General betting rules:

  • Bets are only valid once confirmed by the system and assigned a ticket ID.
  • The minimum bet amount is R$ 2.00; the maximum may vary by market and is displayed before confirmation.
  • Live bets are temporarily suspended during events that change the score (goals, cards, substitutions) until the odds stabilize.
  • If an event is cancelled or abandoned before the minimum regulatory time, bets are voided and the amount is returned to the User's balance.
  • Obvious pricing errors (odds that are clearly incorrect due to a system failure) may be voided by 31win, with a full refund to the User.
  • Parlay bets (accumulators) are allowed; each selection's outcome is independent.

The 31win reserves the right to limit the maximum bet amount on certain markets or for certain accounts, particularly where suspicious betting patterns are identified. Market limitations are applied on a technical basis and do not constitute a penalty against the User.

Bets placed after the official start of a match on pre-game markets may be voided if the system detects that the confirmation time was after the actual event start.
Section 06

Online Casino

The casino at 31win offers more than 3,000 games from a range of certified providers, including slots, European and American roulette, blackjack, baccarat, crash games, and live tables with real dealers streamed 24 hours a day.

All games use an RNG (Random Number Generator) certified by independent auditors, ensuring that results are statistically random and cannot be influenced by third parties or by the 31win. The RTP (Return to Player) for each game is listed in the game's information sheet, accessible directly within the game interface.

Casino-specific rules:

  • Live tables have specific betting limits displayed before each round begins.
  • Progressive jackpots are paid out according to the game provider's rules, which can be found on the game's information page.
  • If a technical failure occurs during a game round and the round cannot be completed correctly, the bet is refunded.
  • The use of automation software, bots, or scripts in casino games is strictly prohibited.
Section 07

Poker

The poker room at 31win offers Texas Hold'em and Omaha across cash game tables and regular tournaments. The platform operates as a neutral operator — it does not participate in hands played by users and only takes the rake (table commission) as set out in the published fee structure.

Poker room rules:

  • The maximum rake per hand is 5% of the pot, with a cap set by the table limit, as published in the room's information section.
  • Tournaments with a guaranteed prize pool have their structures and rules published on the registration page before they begin.
  • Collusion between players is strictly prohibited and monitored by automated systems. Accounts found to be involved in collusion will be closed and balances withheld.
  • The use of poker assistance tools (HUDs, real-time solvers) is prohibited at the tables of 31win.
  • Weekly freerolls are free and open to all registered users. No buy-in required.
Section 08

Bonuses & Promotions

The 31win offers bonuses and periodic promotions subject to specific terms published in each campaign. The general rules that apply to all bonuses are:

  • Rollover (wagering requirement): Deposit bonuses carry a 5x rollover on the bonus amount received, unless otherwise stated in the specific promotion.
  • The rollover must be completed within 30 calendar days from the date the bonus is received.
  • Bets on markets with odds below 1.50 do not count toward meeting the rollover requirement.
  • Cancelled, voided, or partially cashed-out bets do not count toward rollover requirements.
  • Each User may receive the welcome bonus only once. Attempts to claim it multiple times using different accounts will result in the cancellation of all bonuses and accounts involved.
  • The 31win reserves the right to modify, suspend, or cancel any promotion at any time, with prior notice to eligible users whenever possible.
Practical example: If you receive a BRL 100.00 bonus, you will need to wager BRL 500.00 on odds of 1.50 or higher to release the bonus balance for withdrawal. Lost bets also count toward the rollover.
Section 09

Responsible Gambling

The 31win believes that sports betting and casino games are forms of entertainment and should be treated as such — with clear limits and mindful control. That's why we offer responsible gambling tools accessible to any User at any time.

Available tools:

  • Deposit limits: Set daily, weekly, or monthly deposit limits. Decreases take effect immediately; increases take 24 hours to be applied.
  • Session break: Block account access for periods ranging from 24 hours to 7 days.
  • Temporary self-exclusion: Suspend access for 30, 60, 90, or 180 days.
  • Permanent self-exclusion: Permanently close the account. This action is irreversible.

All tools take effect immediately upon request and cannot be reversed before the defined period expires. The 31win does not send marketing communications to users who have an active self-exclusion.

If you notice signs of problem gambling in yourself or someone close to you, please contact the 31win or visit the Responsible Gambling for more information and support resources available in Brazil.

Questions about 31win's Terms

The most frequently asked questions about the platform's rules

No. Each user may only have one active account at 31win. Creating multiple accounts — whether using the same CPF or different documents — violates the Terms and Conditions and results in the immediate closure of all accounts involved, with bonus cancellation and balance retention pending review. If you have forgotten your login or password, use the account recovery option on the login screen before creating a new account.

You may continue using your available balance for Sports Betting and casino games while verification is pending. However, withdrawals are blocked until the identity verification process is successfully completed. If documents are not submitted within a reasonable time after being requested, the 31win may preventively block the account for review. We recommend submitting the required documents as soon as they are requested to avoid any interruption to your use of the platform.

The rollover is the total betting volume you need to wager before you can withdraw a bonus amount. At 31win, the standard rollover is 5x the bonus amount, with a 30-day period and a minimum odds requirement of 1.50 per selection. For example: if you received a R$ 100.00 bonus, you need to wager R$ 500.00 in valid bets to release the balance. Lost bets also count toward the calculation — you don't need to win to meet the rollover. Only cancelled or voided bets are not counted.

In general, withdrawals must be made to the same method and account used for the deposit — this is a security measure to prevent fraud. If you need to withdraw to a different method for a legitimate reason (for example, the bank account has been closed), please contact the support team at 31win before requesting a withdrawal. Our team will guide you through the correct process, which may include additional identity verification. Under no circumstances will withdrawals to third-party accounts (persons other than the account holder at 31win) are permitted.

Under normal circumstances, bets confirmed by the system are binding for both parties — both the User and 31win. The platform may void a bet in specific cases: an obvious pricing error (clearly incorrect odds due to a technical fault), bets placed after the actual start of an event on pre-game markets, or cancellation of a sporting event before the minimum time required for markets to be settled. In all such cases, the wagered amount is returned in full to the User's balance. Bets confirmed due to system error exploitation may be voided without prior notice.
