Throughout the 23 editions of Big Brother Brasil, several tests remained in the public’s memory, whether due to their difficulty, emotion or creativity. From tests of endurance, skill, or even those in which the brothers had to rely on luck.

One of the most iconic tests in the history of BBB was the “Guaraná Test”, held at BBB11. The dynamic was marked by moments of humor, such as participant Paulinha’s falls, which went viral and are still popular on the Internet today.
Another notable moment in the reality show was during the final stretch of BBB19, when Ana Clara and Kaysar broke the record in endurance events after remaining in the competition for more than 42 hours.
Below, check out the list of six iconic tests that marked the history of Big Brother Brasil:
Rivals Diego Alemão and Alberto Cowboy fought in an endurance race, considered one of the most emblematic of the BBB. The blonde was determined to take the lead after returning from the wall that eliminated his lover, Íris Stefanelli.
The ‘Cage Test’ consisted of remaining in a wooden cage in the house’s garden and, whoever came out last, would win the lead. At one point, because of the sun and strong heat, a doctor was called to assess each person’s condition and the participants received sports drinks.
The test lasted more than 21 hours and is one of the longest in the program’s history. In the end, Cowboy was the winner, after Alemão withdrew from the race due to illness.

On that occasion, Eliéser got the better of Fernanda after 19 hours of competition.

My Roast Chicken (BBB11)
The BBB11 participants, dressed as roast chickens, faced an unforgettable endurance test. The dynamic divided the brothers into two groups.

After almost 10 hours of endurance testing, Jaqueline was the winner.
