377bt was built with a clear purpose: to be the sports betting and online casino platform that Brazilian players deserve — with competitive odds, Pix payments, Portuguese-language support, and a sports and games catalog that covers everything Brazilian fans follow.
Six solid reasons why thousands of Brazilians choose 377bt every day
At 377bt, withdrawing is as easy as it gets. Enter your Pix key, confirm the amount, and the money lands in your account — Nubank, Itaú, Bradesco, Banco do Brasil, or any bank — in moments. No fees, no red tape, no waiting until the next day.
Football featuring Brasileirão Série A, Copa do Brasil, and Libertadores, UFC and MMA, NBB basketball, volleyball, e-sports, tennis, Formula 1, boxing, and much more. If it happens in world sports, 377bt has odds on it — with live betting and cash out available.
377bt's live casino tables feature dealers who speak Brazilian Portuguese. Blackjack, roulette, baccarat, and more — all streamed in HD from professional studios so you can play in total comfort, with no language barrier.
377bt handles your data with full responsibility, in compliance with Brazil's General Data Protection Law (LGPD). All communication is protected by 256-bit SSL encryption. Your registration details, CPF, and Pix key are never shared without your authorization.
The 377bt platform is fully responsive — it runs in your mobile browser with no app download needed. Touch-optimized interface, fast live betting, and result notifications delivered directly to your Android or iPhone.
Have a question about a withdrawal? Need help with a bonus? The 377bt support team is available 24/7 via live chat and email — with 100% Brazilian Portuguese service, no robotic scripts.
377bt exists to give Brazilian bettors a betting experience that respects their time, their money, and their intelligence. We got tired of seeing platforms with withdrawals that take days, support that replies in English, and bonuses full of fine print designed to confuse.
We built 377bt on a different premise: transparent rules, fast payments, real support, and a catalog that covers what Brazilians want to watch and bet on — from the Brasileirão to the UFC, from live blackjack tables to the most popular crash games on the market.
Clear bonus rules, terms written in plain Portuguese, and straightforward communication. At 377bt, there's no fine print hiding unfair conditions.
Won? Get paid. Pix is the house standard — processed in up to 90 seconds, any time of day or night, with no withdrawal fee.
377bt provides deposit control tools, self-exclusion options, and dedicated support. Betting should be entertainment — and we want to keep it that way for all our users.
Frequent platform updates, new betting markets, recent games, and improvements based on real user feedback. 377bt never stops evolving.
From launch to becoming a go-to platform for Brazilian bettors — every step was built with a focus on improving the user experience.
The platform launches with a focus on Sports Betting, coverage of the Brasileirão Série A, and Pix payments. The promise of withdrawals in up to 90 seconds captures the Brazilian market's attention from day one.
377bt launches its live casino with Brazilian Portuguese-speaking dealers — blackjack, roulette, and baccarat with HD streaming. The casino section grows rapidly and becomes the second most visited area of the platform.
As Brazilian interest in UFC and e-sports continues to grow, 377bt expands its MMA coverage to all weekly cards and launches specialized markets for CS2, League of Legends, and Free Fire.
377bt operates with over 30 sports, hundreds of casino games, competitive odds, and a growing base of satisfied users. The focus remains the same: delivering the best betting experience for Brazilian players.

The 377bt is a sports betting and online casino platform built with the Brazilian user in mind. Not the generic user from any country — the bettor who follows the Brasileirão Série A on Monday, gets fired up for UFC on Saturday night, and still has time for a live blackjack session after the match. That user deserves a platform that understands the context they live in, the language they speak, and the payment methods they use every day.
Brazil has changed a great deal in recent years when it comes to the betting market. Regulation has advanced, Pix has transformed the way Brazilians move money, and the sports fan betting base has grown significantly. The 377bt kept pace with that evolution — and in many cases, anticipated what the market would need.
377bt's sports coverage starts with football — as it should. Brasileirão Série A and Série B, Copa do Brasil, Copa Libertadores da América, Copa Sul-Americana, and the top state championships including Paulistão, Carioca, and Gaúcho all receive full coverage with pre-match and live betting. For classics like Fla-Flu, Gre-Nal, Choque-Rei, and Derby Paulista, the platform typically offers special markets and boosted odds in the days leading up to each match.
Beyond football, 377bt covers UFC and MMA in depth — full UFC, Bellator, and ONE Championship cards, with round betting, method of victory, and live cash out during fights. NBB basketball, Superliga volleyball, e-sports such as CS2, League of Legends, and Free Fire, and dozens of other sports round out a catalog that rarely leaves the Brazilian bettor without options.
377bt's live casino stands out for a detail that sounds simple but makes a real difference: the dealers speak Brazilian Portuguese. Not English, not Spanish, not European Portuguese — Brazilian Portuguese, with the accent and manner of speaking users are used to. This makes the experience of playing live blackjack, roulette, or baccarat feel far more natural and comfortable.
Tables are streamed in HD from professional studios with quality lighting, trained dealers, and state-of-the-art equipment. The live chat lets you interact with the dealer and fellow players at the table — creating an atmosphere close to a real casino without leaving home. 377bt's live blackjack, for example, offers tables with betting limits from R$ 5.00 to R$ 10,000.00 per hand, catering to different player profiles.
377bt accepts the most popular payment methods used in Brazil: Pix, boleto bancário, Visa and Mastercard credit and debit cards, PicPay, and Mercado Pago. The minimum deposit is R$ 20.00 and processing is instant via Pix — your balance appears in your account within seconds of payment confirmation.
For withdrawals, Pix is king. Under normal conditions, the requested amount reaches the user's bank account — whether Nubank, Itaú, Bradesco, Banco do Brasil, or any other bank with a registered Pix key — in up to 90 seconds. There are no withdrawal fees and the minimum amount is R$ 10.00. This commitment to payment speed is one of the pillars that sets 377bt apart from the 377bt of the many other platforms available in the Brazilian market.
377bt's welcome bonus matches 100% of your first deposit, up to a maximum of R$ 500.00. That means a R$ 100.00 deposit earns R$ 100.00 in bonus funds, giving you R$ 200.00 to bet with. The rollover is 10x within 30 days — terms we consider fair and that are clearly explained in the promotion's conditions, with no hidden fine print.
Beyond the welcome bonus, 377bt offers regular promotions for active users: weekly cashback on Sports Betting, boosted odds on football classics and UFC cards, free bets on special events, and seasonal promotions tied to the biggest competitions on the Brazilian sports calendar.
377bt takes responsible gambling seriously — not as a box-ticking regulatory requirement, but as a core part of how the platform was designed. We provide tools to set daily, weekly, and monthly deposit limits, along with temporary or permanent self-exclusion options for anyone who needs a break.
The platform's Responsible Gambling section provides information on how to recognize problematic gambling behavior and support resources available in Brazil.
