With a R$ 200.00 bonus, you need R$ 2,000.00 in total wagers. Betting an average of R$ 67.00 per day, you can complete the rollover in under a month — no need to push it, just play at your usual pace.
Both losing and winning bets count equally toward rollover progress — not just winning bets. Here are the bet types and games that qualify:

Fortune Tiger, Fortune Ox, Gates of Olympus, Sweet Bonanza, and all slots available on the platform count 100%.
Blackjack, baccarat, roulette, and live game shows with live dealers all count 100% toward the welcome bonus rollover.
Bets on CS2, LOL, Free Fire, and crash games like Aviator and JetX are also counted in full toward the rollover.

When it comes to welcome bonuses in Brazil, it's hard not to be skeptical. There are plenty of "100% bonus" ads that are riddled with traps in practice — 40x rollover, 7-day deadlines, games that don't count, fine print nobody reads. At the 377bt, the approach is different: to offer a welcome bonus that truly makes sense for the Brazilian player, with transparent conditions from the start.
The 377bt welcome bonus is 100% on the first deposit, up to R$ 500.00. If you deposit R$ 100.00, you play with R$ 200.00. Put in R$ 500.00 or more and you get an extra R$ 500.00 in bonus funds — giving you R$ 1,000.00 in balance to start with. The minimum deposit to activate the bonus is just R$ 20.00, one of the lowest in the Brazilian market.
377bt's 10x rollover is well below the market average for online sports betting in Brazil, where rollovers of 20x, 30x, or even 40x are common — making bonuses nearly impossible to actually benefit from. With 10x, the math is simple: if you received R$ 200.00 in bonus funds, you need to place R$ 2,000.00 in total wagers to unlock your balance for withdrawal.
Here's an important detail: both winning and losing bets count equally toward your progress. You don't need to win every bet to complete the rollover — every BRL wagered moves you forward, regardless of the outcome. This makes the whole experience feel much more natural, without the pressure of having to get everything right just to unlock your bonus.
Plus, you have 30 days calendar days to complete the rollover after activating the bonus. With that kind of window, you can bet at your own pace — whether you're following the Brasileirão rounds, watching UFC fights, playing slots on the weekend, or enjoying the Live Casino tables during the week.
The welcome bonus is exclusively for new 377bt users 377bt who have not yet made any deposit. Each CPF is entitled to one account only and, consequently, to a single welcome bonus. That's why it's worth timing it right: make your first deposit with the amount you actually plan to play with — the more you deposit (up to the cap of R$ 500.00), the larger the bonus you receive.
The bonus is available to players aged 18 and over who are residents of Brazil. Identity verification (KYC) may be required before your first withdrawal, but it won't prevent the bonus from being activated immediately after your deposit.
Football is the top sport for completing the rollover at 377bt. With the Brasileirão Série A running virtually year-round, there are matches available from Wednesday through Sunday — dozens of rounds per month, with multiple markets per game. Straightforward bets like match result (1X2), over/under goals, both teams to score, or Asian handicap are great ways to build rollover progress while placing bets you'd make anyway.
A smart approach is to spread your rollover bets over several weeks, targeting the best available odds rather than forcing bets just to hit the requirement. 377bt offers competitive odds on domestic football, and live odds let you jump into bets mid-match when the picture is already clearer.
If you prefer slots or Live Casino, the welcome bonus works just as well in those categories. Bets on slots from 377bt count 100% toward the rollover — meaning every spin on Fortune Tiger, Gates of Olympus, Sweet Bonanza, or any other title on the platform moves your progress forward. With stakes starting from R$ 0.50 per spin on some games, managing your bonus balance is easy and stress-free.
In the live casino, bets on blackjack, baccarat, roulette, and game shows also count in full. The Portuguese-speaking dealer tables are a standout option for players who enjoy real-time interaction. Minimum bet limits at these tables start from R$ 1.00 at live baccarat tables, making them accessible for any bonus amount.
Once you complete the 10x rollover, your bonus balance is automatically converted into real funds in your 377bt account. You'll receive a confirmation by email and through the app. From there, you can withdraw via Pix — typically processed in under 90 seconds — or keep using the balance for bets if you prefer.
There are no extra steps once the rollover is complete — no manual release requests, no additional waiting period. The process is automatic and transparent. In your 377bt account dashboard, the rollover progress bar updates in real time, so you always know exactly where you stand and how much is left to unlock your bonus.
First, activate the bonus before making your deposit — on the 377bt deposit screen, you'll find the option to select the welcome bonus before confirming your amount. If you deposit without activating it, the bonus cannot be applied retroactively. Second, use Pix to deposit: it's instant and the bonus shows up in your balance within seconds. Third, plan your rollover realistically — 30 days gives you plenty of time without any pressure.
Finally, keep in mind that 377bt has other active promotions you can take advantage of alongside your welcome bonus — such as weekly cashback, free spins on Fridays, and special bets on the Brasileirão. The welcome bonus is just the beginning of a full experience on the platform.
