A Nation Passionate About Sport Deserves a Platform That Matches
Brazilians don't have just one favorite sport — they have several. Football holds an undeniable place in nearly everyone's heart, but anyone who thinks it stops there has never been to an NBB basketball game, never watched a UFC fight with a Brazilian crowd going wild, never felt the tension of a Grand Slam tennis match with a Brazilian in contention. Sport in Brazil is diverse, intense, and deeply passionate — and the 66ab was built to cover all of it.
In the Sports section of the 66ab, you'll find over 30 sports available for betting, with events running 24 hours a day, seven days a week. The catalog spans from Brasileirão Série A football to international athletics, plus rugby, boxing, MMA, volleyball, basketball, beach volleyball, and much more. If it's happening in the world of sport, the odds are on 66ab.
What sets 66ab from other platforms is the depth of markets combined with ease of use. You don't need to be an experienced bettor to explore the options — the interface is intuitive, the sport filters work well, and Portuguese-language support is always there when you need it. And when the time comes, Pix withdrawals make sure your winnings land in your account just as fast as you'd expect.

Football: From the Brasileirão to the European Leagues
Football is, without question, the sport with the highest betting volume at 66ab. And it makes sense — the Brazilian calendar is packed: Brasileirão Série A and Série B run alongside the Copa do Brasil, Libertadores, Sul-Americana, and state competitions that draw fans from every corner of the country. Not to mention the European leagues that keep bettors up through the night following the Premier League, La Liga, Bundesliga, and Serie A.
For every Brasileirão match, 66ab offers an average of 60 different markets, including half-time result, over/under 0.5 goals in the first half, total corners, cards, and even the minute of the first goal. That depth lets bettors with real knowledge of the teams find value where the market hasn't priced things correctly — and that's exactly where consistent profit starts.
One thing a lot of people overlook: state football — especially Paulistão and Carioca — offers far more value in its odds than the more closely monitored competitions. Rotated squads, varying motivations depending on where teams are in the season, young players being tested in new positions — the 66ab covers all of that, and the sharp bettor will find opportunities that simply don't exist in the major European markets.
MMA & UFC: Brazil at the Center of the World
Brazil is one of the world's great MMA powerhouses, and UFC is the fastest-growing sport for betting at 66ab over the past two years. And it's no surprise — names like Alex Poatan, Ilia Topuria, and the Brazilians who dominate entire divisions make every UFC card a national event. On fight nights, the 66ab gets incredibly busy.
What makes MMA especially interesting for bettors is the range of markets. You don't have to just pick the winner — you can bet on the method of victory (KO/TKO, submission, decision), the specific round the fight ends in, or whether it goes to the judges' scorecards. MMA markets carry far more open odds than football's 1X2, which means bigger opportunities for those who study fighters' styles carefully.
At 66ab, the biggest UFC and Bellator events get full coverage with pre-match and live betting for every fight on the main card. For major events featuring Brazilian fighters, the number of available markets per fight can reach 25, including exclusive prop bet options that other Brazilian sites simply don't offer.

Basketball, Tennis, and Formula 1: Bets Most People Overlook
While everyone's focused on football, a growing group of bettors on 66ab discovered the hidden value in other sports. Brazilian basketball — especially the NBB — has an impressive technical level, and teams like Flamengo, Franca, Bauru, and Mogi das Cruzes produce tightly contested matchups that the market often doesn't price with the attention they deserve. That means bettors who follow the league closely find value situations far more often than in the Brasileirão, where the market is much better informed.
In tennis, the Grand Slams are the highlights of the calendar, but the ATP and WTA tournaments during regular weeks are where the real value lies. Players in peak form, favorable surfaces, accumulated fatigue from recent tournaments — those who follow the circuit closely can spot when a favorite arrives at a tournament worn down, or when a rising young player has everything lined up for an upset. The 66ab covers more than 200 tennis tournaments per week, with total games and set handicap markets that are especially appealing to experienced bettors.
What about Formula 1? Motorsport betting is still underrated in Brazil, but those who have started exploring that market at 66ab knows that pole position and podium odds carry real value at rounds where weather conditions or circuit-specific performance favor certain drivers. With the Brazilian GP at Interlagos being one of the most anticipated events on the calendar, F1 betting has grown significantly on the platform — and the odds tend to be far more generous than in team sports.
Practical Tips for Bettors at 66ab
- Specialize in one or two sports before branching out — deep knowledge beats scattered bets every time.
- Use the live market to confirm trends you spotted before the match.
- In Brazilian football, be wary of very short odds on teams that have had a heavy travel schedule during the week.
- Parlays increase risk — combine no more than three high-confidence selections.
- Set a monthly bankroll and never stake more than 5% of it on a single bet.
- In MMA, method-of-victory bets offer better value than straight winner bets.

What Bettors Are Saying About 66ab
"I've been betting on football for years and tried several sites before landing on 66ab. What won me over was the sheer range of markets for the Brasileirão — you can bet on each half's goalscorer, corners, everything. I win more because I can find value in markets other sites simply don't offer."
"I started out betting on football and gradually discovered other sports on 66ab. These days I bet a lot on UFC — the method of victory markets are incredible. In the last event featuring a Brazilian fighter, I called KO in round 1 and turned R$ 80.00 into R$ 2,600.00. The Pix hit my account in 4 minutes."
"I've been betting on the NBB ever since I discovered the basketball markets on 66ab. Most platforms don't even cover the Brazilian league. Here you get result, handicap, total points, and even top scorer of the game. With knowledge of the competition, these bets offer real value."
