If you've ever been let down by bonuses from other sportsbooks — the kind that look great in the ads but hide conditions that are nearly impossible to meet — you'll understand why 31win was built differently. Here, promotions have clear rules from the start — realistic rollovers, honest deadlines, and Portuguese-language support to answer any questions along the way.
The 100% welcome bonus up to BRL 500.00 is the right place to start. Deposit whatever you can, and we'll match it. No promo code needed, no customer service calls, no manual approval. The credit shows up in your account automatically within 5 minutes of your deposit being confirmed. Simple and straightforward.
But what really sets 31win from the competition is the consistency of the promotions. It's not just the initial bonus — it's the cashback every Monday, the free spins every Friday, the odds boost when Flamengo plays in the Libertadores, the monthly slots tournament with real cash prizes, and the poker freeroll every Sunday. Regular players quickly notice that the platform genuinely wants you to stay and have fun.
The weekly cashback deserves a closer look. Many platforms offer cashback loaded with fine print. At 31win, the calculation is based on your net weekly losses — what you actually lost, after subtracting winnings — and the credit is applied every Monday at 10 AM, no request needed. For Diamond members, that means up to 15% back every week, which completely changes the equation for regular bettors.
For football fans, the special promotions for Brasileirão Série A, Copa do Brasil, and Copa Libertadores are in a league of their own. During the Libertadores knockout stages, for example, 31win boosts odds on the biggest matchups by up to 20%. If you were going to bet R$ 100.00 on odds of 2.00, with the boost they become 2.20 — and over the course of a season, that difference adds up to a significant amount of extra BRL in your pocket.
The referral program is also a great source of extra income for anyone with friends who enjoy betting. Every referred friend who signs up and makes a minimum deposit of R$ 50.00 at 31win earns you R$ 50.00 — with no cap on referrals. Refer five betting friends and that's R$ 250.00 in credits. Your referral link is available directly from your account dashboard.
Casino fans will find plenty to love in the promotions at 31win a packed calendar. The monthly slots tournament distributes R$ 30,000.00 in prizes among the top 20 players, and entry is automatic for anyone who plays the selected slots during the period. No sign-up required, no entry fee. Just play and rack up points on the leaderboard.
For poker players, the weekly Sunday freeroll is one of the highlights. With a guaranteed prize pool of BRL 10,000.00 and completely free entry for registered members, it's a real opportunity to win money without risking anything. The tournament takes place every Sunday at 6 PM, and registration opens via the poker room lobby 24 hours in advance.
One important thing: at 31win, transparency is the rule. Every promotion has its terms and conditions written out clearly, with no fine print hiding surprises. The rollover is disclosed before you activate any bonus, and the time left to complete it is shown in real time on your account dashboard. If you have any questions, our Portuguese-language support team is available 24 hours a day via live chat.
Finally, it's worth highlighting that the promotions at 31win are available exclusively to players with a verified account who are 18 or older. Responsible gambling is a core part of our commitment to Brazilian bettors. Use bonuses to have fun, set your deposit limits, and enjoy the experience in a healthy way.
Pix deposits available 24/7, including holidays. Minimum amount R$ 20.00.
Rollover is the number of times you need to wager the bonus amount before you can withdraw. Example: a R$ 100.00 bonus with a 5x rollover means you need to place a total of R$ 500.00 in bets (at minimum odds of 1.50) to unlock your withdrawal. 31win has one of the lowest rollovers in the Brazilian market.
