The 31win was built with one clear goal: to create the best sports betting and online casino experience for Brazilian players. Pix withdrawals in minutes, boosted odds on the Libertadores, a poker room in Portuguese, and a support team that truly understands Brazilian fans.
The 31win is a sports betting and online casino platform built specifically for the Brazilian market. Since day one, the goal has never changed: to deliver an experience that respects the way Brazilians enjoy betting — fast, in Portuguese, with Pix, and without unnecessary hassle.
The name 31win draws from the comeback spirit that defines Brazilian football: the game is never over until the final whistle blows. That same spirit shapes how the platform was built — always pushing to improve, always listening to players, always looking for the next way to deliver something better than what's already out there.
Today at 31win covers Sports Betting across more than 30 sports, with a strong focus on football — Brasileirão Série A, Copa do Brasil, Libertadores, Série B, Campeonato Paulista, Carioca, and the major international tournaments. Beyond football, the platform offers betting on basketball (NBB and NBA), volleyball, MMA and UFC, e-sports, and much more. The casino features over 3,000 games: slots, roulette, blackjack, baccarat, crash games, and live tables with real dealers streaming 24 hours a day.
31win's poker room 31win is built for the Brazilian player who wants to play Texas Hold'em and Omaha against other Brazilians, with a Portuguese-language interface, tournaments with a guaranteed prize pool every week, and cash games with stakes for every bankroll level. Weekly free freerolls let new members step into the competitive environment without spending a thing — just create an account and register.
On the financial side, 31win was built to work like any modern Brazilian digital service: Pix as the primary deposit and withdrawal method, no red tape. Deposit balances hit your account in seconds; Pix withdrawals are processed in up to 15 minutes, around the clock — including late nights, weekends, and holidays. Boleto bancário, credit and debit cards, PicPay, Mercado Pago, and TED transfers from banks like Nubank, Itaú, Bradesco, and Banco do Brasil are also accepted.
Security and responsibility aren't just buzzwords at 31win — they are concrete practices. All financial transactions are encrypted with SSL protocol. The two-factor authentication system protects user accounts. And the Responsible Gambling section offers real tools: daily, weekly, and monthly deposit limits, session breaks, and temporary or permanent self-exclusion. Because believing in entertainment with responsibility is part of what defines who 31win is.
In 2026, 31win launched a full redesign of the mobile interface, making the site even faster and more accessible on Android and iOS without requiring any app installation. Today, over 70% of platform visits come from mobile — and the entire experience has been optimized for it, from sign-up to withdrawal.
What sets us apart in an increasingly competitive market
Deposit at 31win via Pix is instant — the balance hits your account in seconds. For withdrawals, processing takes up to 15 minutes at any time of day, including overnight and on holidays. No waiting for business days, no email confirmation hoops to jump through. That's the speed of Pix applied to entertainment.
From the interface to support, everything at 31win is in pt-BR. Live chat runs 24 hours a day with agents who know Brazilian football, understand the questions local players actually ask, and respond in natural Portuguese — not the stiff, machine-translated kind. That's what sets a platform built from the ground up for Brazil apart from the rest.
Every Copa Libertadores match featuring Brazilian clubs gets an automatic +20% odds boost at 31win. No promo code needed, no separate sign-up. Odds already appear adjusted in the game listings. It's our way of celebrating the continental football Brazil loves so much.

Transactions protected by SSL encryption, two-factor authentication, and continuous suspicious activity monitoring. All casino games use certified RNG. In the Responsible Gambling section, you can set deposit limits, session breaks, and self-exclusion in just a few clicks. Security isn't a promise — it's infrastructure.
Slots from the world's top providers, European and American roulette, blackjack, baccarat, crash games, and live tables with real dealers streaming 24/7. At 31win, the casino has something for every type of player: from the casual user who wants to spin a quick slot to the strategic player who prefers a live baccarat table at 3 in the morning.
The 31win was built on solid principles — not just words on a wall, but criteria that guide technical, product, and customer service decisions every single day.
The 31win is built by people who understand betting, technology, and the Brazilian market from the inside out.
