"I tested it quite a bit before trusting it. But 399w really does pay out — and fast! I requested a withdrawal of R$ 3,200 via Pix and it hit my account in under 3 minutes. I've never seen that on any other site."
"I watch Brasileirão every weekend and always make the most of the odds on 399w. The difference in returns compared to what I used before is clear as day. I've already moved up to VIP Gold!"
"Support sorted out my issue in under 2 minutes on chat. I explained the situation and they fixed it on the spot. That's not something you see often in this industry. The app is great too — zero lag whatsoever."
"I won the daily roulette twice this week! One time it gave me 30 free spins, the other a R$ 25 bonus. Small rewards, sure, but it shows it's the real deal. I'd recommend it to everyone I know."
"I'm a huge UFC fan and 399w has the best MMA odds I've found in Brazil. During Poatan's UFC Fight Night, I placed live bets and the adrenaline was on another level. Kudos to the team!"
"The Live Casino has Brazilian dealers, and that makes a huge difference. I feel right at home playing blackjack. Clean interface — none of that visual clutter you get on other sites."

If you follow the Brasileirão, live for the Copa do Brasil, or never miss a UFC fight when a Brazilian is on the card, the 399w was built for you. It's a Sports Betting and online casino platform developed with the Brazilian market at its core — from sign-up to your first withdrawal, every step designed around the way Brazil plays.
399w was built to fill a real gap: Brazilian bettors who wanted a sportsbook that worked great on mobile, paid out fast via Pix, and offered genuine Portuguese-language support — not some generic chatbot that never actually solves anything. From day one, the mission was straightforward: transparent odds, fast payments, and an experience that respects the user.
In football, the coverage at 399w covers everything from Brasileirão Série A and Série B to the Copa do Brasil, Libertadores, Sul-Americana, and even state championships like Carioca and Paulistão. Odds update in real time, and you can bet before the match or live as the action unfolds. If Flamengo drew in the first half and you think they'll turn it around, there's a market for that.
Beyond football, 399w covers a wide range of sports: volleyball, basketball (NBB), tennis, e-sports like CS2 and Valorant, and of course MMA and UFC. Fights featuring Brazilian athletes — Alex Poatan, Charles do Bronx, Amanda Nunes — get special coverage with extra markets and boosted odds.
The 399w casino brings together over 12,500 games from providers like Pragmatic Play, Evolution, NetEnt, and Play'n GO. Themed slots, live roulette with Portuguese-speaking dealers, blackjack, baccarat, and fan-favorite crash games like Aviator are all available around the clock. Games load fast and run smoothly even on entry-level smartphones.
To deposit and withdraw, the 399w accepts every payment method Brazilians use every day: Pix, boleto bancário, credit and debit cards, PicPay, Mercado Pago, and TED bank transfers through major banks like Nubank, Itaú, Bradesco, and Banco do Brasil. The minimum deposit is R$ 20.00, and Pix withdrawals hit your account in minutes.
399w's bonuses are designed to be fair and straightforward. The welcome bonus offers up to R$ 500.00 on your first deposit. From there, the VIP Program delivers increasing cashback, weekly reload bonuses, access to exclusive tournaments, and at the Diamond tier, a dedicated account manager and personalized perks.
Platform security is taken seriously. 399w operates under a valid gaming license, uses 256-bit SSL encryption on all transactions, and follows LGPD guidelines for personal data protection. Identity verification (KYC) is in place to keep the platform safe and fraud-free for everyone.
At the end of the day, 399w wants to be more than just another sportsbook. The goal is to be the platform Brazilians choose because they trust it, because it works, and because it delivers on its promises. Create your account now, claim your welcome bonus, and find out why over 4 million Brazilians have already chosen 399w for their bets.
