Activating any promotion on 377bt is straightforward with no hidden catches. Just follow the steps below:
If you don't have a 377bt account yet, registration is free and takes less than five minutes. Existing users just need to log in with their email and password.
In your account dashboard, go to "Promotions" or click directly on the banner of the offer you want. Each promotion has its own page with full details.
Click "Activate" or "Claim" on the promotion you've chosen. Some offers are activated automatically once the conditions are met — such as the weekly cashback.
For promotions that require a deposit, use Pix, boleto, card, or another available method. The minimum deposit is R$ 20.00 for most offers.
Once you meet the wagering requirements (rollover), the bonus is converted into real withdrawable funds via Pix. Simple, transparent, and no surprises.
The rollover (also known as the wagering requirement) is the number of times you need to wager your bonus amount before it can be converted into withdrawable funds. At 377bt, rollovers are among the lowest in the market.
You received a R$ 100.00 bonus with a 10x rollover. That means you need to place bets totaling R$ 1,000.00 to unlock the bonus for withdrawal. Both winning and losing bets count toward the requirement — not just the winning ones.
Most 377bt promotions carry a 5x to 10x rollover — well below the average for the Sports Betting market in Brazil.
You have 30 days to meet the rollover on any active bonus in your account. No need to rush and bet it all at once.
Bets on football, UFC, NBB basketball, and other sports count 100% toward fulfilling the rollover on sports bonuses.
In your account dashboard, you can see how much you've already wagered and how much is left to complete the rollover on each active bonus — updated in real time.

One of the things that sets 377bt from other betting platforms is the quality and variety of promotions on offer — especially for Brazilian players. It's not hard to find sportsbooks that promise huge bonuses with terms that are nearly impossible to meet. 377bt took the opposite approach: real-value promotions, fair rollover requirements, and terms written in plain language, with no fine print hiding any surprises.
377bt's promotions page is updated weekly with fresh offers. There's something for every type of player: football fans, slots enthusiasts, those who love Live Casino with Portuguese-speaking dealers, and UFC viewers who tune in every Saturday. The goal is for each promotion to genuinely matter to Brazilian players — not just look good on a banner.
Anyone who opens an account at the 377bt for the first time is eligible for the 100% welcome bonus on the first deposit, up to R$ 500.00. That means if you deposit R$ 200.00 via Pix, you'll play with R$ 400.00 — double what you put in. The minimum deposit to activate the bonus is R$ 20.00, making this offer accessible to all player types.
The welcome bonus rollover is 10x, one of the most competitive in the Brazilian market. You have 30 days to meet the requirement, and bets on football, UFC, NBB basketball, slots, and Live Casino all count toward your progress. You don't have to wager it all at once — go at your own pace while enjoying the platform.
377bt's weekly cashback is automatic — you don't need to do anything to receive it. At the start of each week, the platform calculates the previous week's net losses and deposits the cashback percentage corresponding to your VIP level directly into your account. For members at the Gold and Diamond, the cashback comes with no additional rollover — meaning you can withdraw the amount received directly via Pix.
This promotion exists because 377bt understands that gambling has its ups and downs, and loyal players deserve to be recognized even during tough weeks. Cashback doesn't fix everything, but it's an honest way for the platform to share the risk with regular players.
Football is the national passion, and 377bt celebrates that with exclusive free bets every matchday of the Brasileirão Série A. Players who bet on at least three matches from the previous round receive a R$ 50.00 free bet to use in the next round, with no rollover on winnings. It's the platform's way of rewarding those who follow the league closely — and adding extra excitement to weekend games.
Beyond the Brasileirão, 377bt also creates special bets for the Copa do Brasil, Libertadores, and regional derbies — such as Fla-Flu, Gre-Nal, and Choque-Rei — with exclusive boosted odds for registered users. These offers appear in the promotions section, typically 48 hours before the event.
For slots lovers, 377bt's weekly tournaments are one of the platform's highlights. Every weekend, the 100 players who accumulate the most points on participating slots share a prize pool of R$ 50,000.00. The leaderboard updates in real time within the platform, so you can track your position and decide whether to ramp up your bets to climb the rankings.
The slots featured in the tournament are rotated weekly from titles by providers such as Pragmatic Play, PG Soft, and Hacksaw. Fortune Tiger, Fortune Ox, Gates of Olympus, and other Brazilian favorites regularly make the list. Prize money is credited via Pix by Monday after the tournament closes.
377bt has one of the most rewarding referral programs available in Brazil. For every friend you refer who makes their first deposit on the platform, you receive R$ 50.00 in bonus credited to your account — and the referred friend also gets an extra R$ 30.00 on top of the standard welcome bonus. There's no referral limit, meaning the more friends you bring in, the more you earn.
The credit is applied automatically after your referred friend makes their first deposit. To take part, simply share your unique referral link, available in the account dashboard under the "Refer a Friend" section. It's an easy way to enjoy 377bt benefits without necessarily needing to bet more.
At 377bt, all promotion terms and conditions are available in plain language, directly on each offer's page. Before activating any bonus, you can review the required rollover, the completion deadline, which games count toward the requirement, and any other relevant conditions. No unpleasant surprises at withdrawal.
If you have any questions about a specific promotion — whether it's how cashback is calculated, the deadline on a free bet, or how the tournament leaderboard works — 377bt's live chat is available 24/7, with support in Portuguese from a Brazilian team.
