Create your account, deposit from R$ 20.00 via Pix, and receive a 100% bonus on your deposit. Use it on football, UFC, volleyball, slots, live casino, crash games, and much more.
Welcome bonuses exist at practically every Sports Betting site in Brazil. The problem is that most come loaded with impossible conditions — 30x rollover, 7-day deadlines, restrictions on half the available games. At 45kk, the approach is different: 100% on your first deposit up to R$ 500.00, with clear rules and a fair deadline to meet the conditions.
Here's how it works: create your account for free, make your first deposit of at least R$ 20.00, and 45kk automatically credits 100% of that amount as a bonus. Deposit R$ 100.00? You get an extra R$ 100.00 in bonus funds, giving you R$ 200.00 to bet with. Deposit R$ 500.00? You start with R$ 1,000.00 in balance. Simple as that.
The bonus can be used across all categories available at 45kk — football with bets on the Brasileirão, Copa do Brasil, and Libertadores, UFC and MMA, volleyball, NBB basketball, e-sports, slots, Live Casino, and crash games. There are no category restrictions: you decide where to use the extra balance.
The welcome bonus is just the beginning. See what else 45kk has in store for you.
In under 3 minutes your bonus is credited and ready to use.
Rollover is the wagering requirement you must meet before withdrawing any bonus-derived funds. It is standard practice across betting sites worldwide — 45kk follows the same model, but with more reasonable conditions than the market average.
The 45kk welcome bonus has a 10x rollover on the bonus amount. That means if you received R$ 100.00 in bonus funds, you need to place R$ 1,000.00 in bets before you can withdraw the converted balance. You have 30 days to meet this requirement.
Practical example
Bets that count toward the rollover
Sports bets with odds above 1.50 and Live Casino bets count 100% toward the rollover. Slots contribute 50%. Cancelled or voided bets do not count.
The bonus balance works across virtually the entire platform. Check out the available categories:
Sports Betting

How much bonus you can earn based on your deposit amount:
Every Brazilian bettor has come across a flashy promotion that, at the time of redemption, comes with a list of impossible conditions. A 40x rollover, a 5-day deadline, restrictions to a single category — these exist to ensure most people never see that money. The 45kk made a different choice: to offer a bonus with conditions that any regular bettor can meet through their normal play.
A 10x rollover with a 30-day window is one of the fairest available in the Brazilian market. Consider that you deposited R$ 200.00 and received another R$ 200.00 in bonus funds. To unlock that bonus, you need to place R$ 2,000.00 in wagers within a month. Anyone who bets regularly on the Brasileirão — averaging three matches a week at R$ 20.00 to R$ 30.00 per bet — will naturally get close to that amount without changing their habits.
Another advantage of the 45kk bonus is how flexible it is. Many platforms restrict bonuses to Sports Betting only or limit them to a handful of casino games. Here, you can use it across any category — from a bet on Flamengo in the Brasileirão to a live baccarat table, slots, and crash games. That freedom lets you put the extra balance exactly where you feel most confident and knowledgeable.
The redemption process is transparent. In your 45kk account area, you can track in real time how much of the rollover you've completed, how much is left, and how much time remains. No surprise expired bonuses without warning — the system sends you a notification when you're 72 hours from the deadline, giving you time to organize your remaining bets.
It is important to understand the difference between real balance and bonus balance on the platform. When you deposit R$ 100.00 and receive R$ 100.00 in bonus funds, 45kk keeps these two amounts separate in your account. Your real balance can be withdrawn at any time with no restrictions. Your bonus balance is available for wagering but is only converted into withdrawable funds once the rollover requirement is met. This separation eliminates confusion and ensures you always know exactly what you are working with.
Beyond the welcome bonus, 45kk runs a recurring promotions calendar that rewards players who keep betting on the platform. Every weekend — especially on days packed with Brasileirão fixtures — the platform offers boosted odds on selected matches. During UFC and MMA events, targeted promos appear, such as risk-free bets on main card fights. In the CBLOL playoffs, exclusive reload bonuses for e-sports are usually available.
The referral program is another source of bonus funds that many users overlook. For every friend you refer who makes their first deposit at 45kk, you receive R$ 30.00 in bonus balance. There is no referral limit — bring in 10 friends and that is an extra R$ 300.00 in bonus funds to use however you like. Your referral link is available in your account area; just share it.
For those just getting started or switching from another platform, the 45kk welcome bonus is a real opportunity to explore the platform with more room to learn. With double the balance, you can try different markets — attempt the parlay you'd normally avoid, experience Live Casino for the first time, or bet on a sport you're still learning — without putting your entire initial balance on the line at once.
45kk was built for the Brazilian market, and that includes deposit methods: Pix with instant approval, boleto bancário, credit and debit cards, PicPay, and Mercado Pago. The bonus is credited regardless of which method you choose — no specific payment method is required to qualify for the promotion. Create your account, activate the bonus, and make your first deposit. You will discover the rest as you go.
