399w was built with a straightforward purpose: to deliver a Sports Betting and online casino platform that genuinely works for the Brazilian bettor — with competitive odds, BRL payments via Pix, support in Portuguese, and promotions that actually make sense.
A 399w was founded by a group of professionals who knew the betting market well — both from the technology development side and from the side of someone who actually bets. The frustration was always the same: international platforms with English interfaces, slow support, unpredictable exchange rates, and payment methods that were never the ones Brazilians use in daily life.
The idea from day one was to build something different — a platform where everything runs in BRL, where Pix withdrawals hit your account in minutes, where support answers in Portuguese and actually understands the Brazilian bettor's context, and where promotions have terms that make sense instead of impossible rollovers buried in fine print.
Today the 399w is one of the fastest-growing platforms in Brazil, with users in every state, full coverage of the Brasileirão, Copa do Brasil, Libertadores, UFC, and much more — and a team that keeps expanding the product based on what Brazilian bettors actually want and need.
The platform launches with a focus on the Brazilian market: a Portuguese-language interface, Pix payments, and full coverage of domestic football — Brasileirão, Copa do Brasil, and state championships.
399w expands into MMA and UFC betting — keeping pace with the sport's growth in Brazil — and launches Live Casino with real-time dealers and the first crash games.
The 399w VIP Program operates across five tiers — Bronze, Silver, Gold, Platinum, and Diamond — with automatic weekly cashback of up to 25% for the most active members.
399w launches its fully mobile-optimized version, bringing every desktop feature — live betting, casino, and Pix withdrawals — straight to your smartphone.
399w has surpassed 500,000 registered users, with over 2,000 events covered per month and a Portuguese-language support team available 24 hours a day, seven days a week.
Six reasons why over 500,000 users have chosen 399w as their primary betting platform.
At 399w, Pix deposits are confirmed in seconds and withdrawals are processed in under 5 minutes — 24 hours a day, including late Saturday nights after the UFC card. No banking hours, no business days. Pix works when you need it.

📡 Live — 2,000+ events/month399w's support is 100% in Brazilian Portuguese — no agents responding with machine-translated scripts or lacking any understanding of the Brazilian bettor's context. Live chat is available around the clock, with an average response time under 2 minutes, every day of the week.
💬 Average response time: 2 minAll personal and financial data on 399w is protected with 256-bit SSL encryption — the same standard used by Brazil's leading banks. The platform operates in compliance with the LGPD (General Data Protection Law, Law No. 13,709/2018) and carries out KYC identity verification to ensure the security of all users.
🔒 SSL 256-bit · LGPD399w's welcome bonus carries a 5x rollover — one of the lowest in the Brazilian market. VIP cashback is credited automatically every Monday, no need to contact support. These promotions were designed to actually be used, not just to look attractive on paper while being impossible in practice.
🎁 Bonus up to R$ 500.00The 399w mobile experience was built to perform on Brazilian phones — over 4G or Wi-Fi, on any Android or iOS device. Live betting, casino, Pix deposits, and results tracking all run smoothly straight from your mobile browser, with no app download required.
📱 Android & iOSThere's a big difference between a betting platform built for the global market and later adapted for Brazil, and one that was designed with the Brazilian bettor in mind from day one. The 399w falls into the second group — and that changes everything, from how payments work to the type of content that appears on the platform.
Brazilian bettors have a very specific profile. Most bets are placed on mobile, not desktop. Pix is the preferred payment method — and the expectation is that it works as fast as it does in any other part of their financial life. Football is the central sport, but Brazilian audiences are also deeply passionate about UFC, NBB basketball, and e-sports like CS2 and League of Legends. Bettors want Portuguese-language support that understands their context, not a chat that replies with machine-translated text lacking any local awareness. The 399w was built with exactly that profile in mind.
The sports coverage at 399w puts the spotlight on what Brazilian fans actually follow. Brasileirão Série A with every match available for live betting — from marquee clashes like Flamengo x Palmeiras to midweek rounds. Copa do Brasil with full coverage across all stages, including both legs of knockout ties. Copa Libertadores with a special focus on Brazilian clubs. UFC with complete cards — main event, co-main, main card, and prelims — plus round-by-round and method-of-victory markets. NBB covering the top rounds of Brazil's national basketball league. E-sports with CS2, League of Legends, and Valorant coverage, with extra attention on Brazilian teams like FURIA and paiN Gaming.
When it comes to payments, this is where 399w truly stands out in practice. All transactions are in BRL — no exchange rates, no currency conversion, no surprises on your bank statement. The minimum deposit is R$ 20.00 and can be made via Pix, boleto bancário, credit or debit card, PicPay, Mercado Pago, or TED bank transfer through the country's major banks — Nubank, Itaú, Bradesco, Banco do Brasil. Withdrawals are processed exclusively via Pix, in under 5 minutes, available 24 hours a day. That includes late Saturday and Sunday nights — which is exactly when most UFC cards and late-night Brasileirão rounds wrap up.
The promotions at 399w have been one of the most carefully developed features since the platform launched. The team behind them was deliberate about creating a welcome bonus with a 5x rollover — one of the lowest in the Brazilian betting market. That means the bonus is real, not just marketing. The weekly VIP cashback is fully automatic: no need to contact support, no button to click — it shows up in your account every Monday based on your VIP level. The Weekly Slots Tournament distributes R$ 50,000.00 in real prizes every Sunday. The accumulator bonus automatically applies an extra percentage when you build a combo with three or more selections. Everything works the way it should.
Responsible gambling is something the 399w. The platform provides real self-control tools: daily and weekly deposit limits, session time limits, temporary account suspension, and permanent self-exclusion. All of these tools are accessible directly in your account settings, with no red tape.

The platform is exclusively for users aged 18 and over and verifies age for every registration.

The support team is trained specifically for the Brazilian bettor's context and has the authority to resolve most issues on the first contact, without escalating to other departments. The tips team consists of analysts who specialize by sport — football, MMA, basketball, e-sports, and volleyball — with a historical performance record that is published and updated regularly in the platform's Tips section.
A 399w is a platform in constant growth — not in the vague sense of "always improving," but in the literal sense of shipping new features, expanding sports coverage, and opening new markets based on what users actually ask for and use. Feedback from the betting community that chose 399w as their primary platform drives every product decision. The long-term goal is straightforward: become the go-to sports betting platform in Brazil for bettors who take the experience seriously.
