Rollover at licensed sites in Brazil
Brazil's Law 14,790, which regulates fixed-odds betting in the country, bans sign-up bonuses tied to a first deposit — which is why that kind of offer has largely disappeared from licensed sites. Even so, promotions like cashback, boosted odds, and referral bonuses still exist, and they almost always come with rollover rules: a multiple of the amount you must wager before the balance can be withdrawn.
Reading those rules before accepting any promotion is what decides whether it's worth it. A high rollover combined with the house margin can turn an apparently generous bonus into something that costs more than it delivers — this calculator only translates that math into numbers, without promising the final result will be positive.
