Next up, we have 1xBet. They're relatively new to the game, but 💯 they're already making waves. Their odds are competitive, and they offer up to R$500 in welcome bonuses. Not too shabby!

Another 💯 contender is Betano. They're offering up to R$500 in freebets for new customers. That's a great way to get started 💯 without breaking the bank. Plus, their odds are pretty great too.

Last but not least, we have KTO. They're still a 💯 newer site, but they're already gaining popularity. They offer a 100% bonus up to R$500, which is nothing to sneeze 💯 at. Plus, their odds are pretty competitive.
