From the Brasileirão Série A to the Copa do Brasil, from the Libertadores to the UFC, bet665 covers it all with competitive odds, a wide range of markets, and integrated live streaming. Bet in real time straight from your phone.
Over 20 sports covered in depth, from football to e-sports.
Live and upcoming events with the best odds on the market.
For every game, you have dozens of different ways to bet.
The most classic market. You bet on a home win, a draw, or an away win. Available on every football match.
Harder to hit, bigger the reward. Predict the exact final score and multiply your winnings with sky-high odds. A fan favorite for Brasileirão classics.
Bet on whether both teams will score at least one goal. The final result doesn't matter — all that counts is whether both sides hit the net.
Level the playing field in unbalanced matchups. The favorite starts at a disadvantage while the underdog gets a head start, bringing the odds closer together.
Bet on the total number of goals in a match. Over 2.5 means you need 3 or more goals. Also applies to corners and cards.
Combine multiple games into a single bet to multiply your winnings. The more correct selections, the higher your accumulated return.
Bet on which player will score next, the first goal, or any goal in the match. Attractive odds on in-form strikers.
Place bets while the action is happening. Odds update every second as the score, ball possession, and stats change.
Cash out part of your winnings before the match ends. Useful for locking in profit when your bet is winning or limiting losses when it's going the other way.
When a Brazilian decides to start betting on football or any other sport, the choice of platform matters far more than it might seem at first. Better odds make a real difference over time, withdrawal speed completely changes the experience, and coverage of local competitions determines whether you can actually bet on what you follow. bet665 was built with all of these priorities in mind.
In football — by far the most bet-on sport in Brazil — bet665 offers full coverage of the Brasileirão Série A and Série B, Copa do Brasil, Conmebol Libertadores, Conmebol Sul-Americana, Campeonato Paulista, Carioca, Mineiro, Gaúcho and dozens of other state competitions. It's not just about the final result — there are over 47 markets per match, including exact score, both teams to score, total goals, Asian handicap, top scorers, and live betting with cash out available.
Bet665's live betting feature is one of the platform's strongest suits. Odds update automatically every second as the match progresses — if the favorite concedes a goal, the odds shift instantly, opening up new opportunities. For those who like to cash out, you can settle your bet before the final whistle and secure part of your payout even while the game is still going.
The bet665 live betting interface is highly visual, featuring a real-time scoreboard, match statistics (possession, shots on target, corners, cards) and the main markets laid out clearly. On mobile, the experience is even smoother — the app was built specifically for 4G and 5G connections in Brazil, with no lag or delays to throw off your live betting timing.
Brazil is one of the countries with the most athletes in the UFC, and bet665 reflects that. Every UFC event gets full coverage with markets that go beyond the final result — you can bet on the method of victory (knockout, submission or decision), the round in which the fight ends, and even fighter control inside the cage. With names like Alex Poatan, Amanda Nunes, Deiveson Figueiredo, Renato Moicano and José Aldo constantly appearing on the cards, there's always a reason for Brazilian fans to tune in.
For basketball fans, bet665 covers the Liga Nacional de Basquete (NBB), the NBA and the top European leagues. In volleyball, both the Men's and Women's Superliga get full coverage, making bet665 one of the few platforms that truly goes deep on the sport in the Brazilian market.

Real experiences from people who use the platform every day.
"I've been betting on football for years, and bet665 is by far the site with the most markets on the Brasileirão. I can bet on things that simply don't exist anywhere else — like the number of corners in the second half. It's a whole different level."
"I placed a 5-fold parlay on Libertadores matches and it came in. I withdrew R$ 2,800.00 via Pix and the money hit my account in eight minutes. I'd heard about how fast bet665 was, but experiencing it firsthand is something else. I'm not switching."
"I started betting on UFC through bet665 and was blown away by the available markets. You can bet on method of victory, exact round, and two different fighters on the same slip. For MMA fans, this is the place to be. The app also runs perfectly on mobile."
