Big Brother Brasil 24 was the twenty-fourth season of Big Brother Brasil, which premiered on Monday, January 8, 2024, on TV Globo. The show was produced by Globo and hosted by Tadeu Schmidt, who returned for his third season as the host.

This season had 100 days of confinement, tied with the 21st, 22nd and 23rd as the longest seasons of the reality show ever shown.

For the first time, the grand prize is R$ 2.92 million without tax allowances, the biggest prize in the history of the series, and a 2025 Chevrolet Trailblazer car, plus a R$150,000 prize offered to the runner-up and a R$50,000 prize offered to the housemate in third place.

Like the previous seasons, the show features housemates divided into two groups: "Celebrities", composed of actors, singers, athletes and social media personalities, and "Civilians", composed of everyday Brazilians. A third group consisting of a second batch of civilians called the "Annexes" was introduced as part of the season's opening twist where of 14 hopefuls (including one of who left during the voting process), 8 entered the house, bringing the total number of housemates to a record breaking number of 26 housemates.

On April 16, 2024, 21 year-old app driver Davi Brito won the competition with 60.52% of the public vote over agricultural engineering student Matteus Amaral and dancer & digital influencer Isabelle Nogueira. In addition, the winner received a documentary about his life, produced by Globoplay.

The game The house The twenty-fourth season of Big Brother Brasil presents a remodeled house inspired by fairy tales and fiction stories. The rooms incorporate magical elements, such as a clock that serves as a withdrawn button, a bathroom themed after a wishing well, and a Diary Room that transforms into a magical winter garden. The Have-Not and Have kitchens have distinct decorations, reminiscent of a medieval tavern and combining modernity with optical illusions, respectively. In addition to the traditional three bedrooms, the house also has an extra room on the second floor, with magical and astronomical decor. The outdoor area simulates an enchanted forest divided between day and night. The gym features stone decorations, torches, and war trophies. The house aims to create a fantastic atmosphere, incorporating elements from various imaginary universes.

Mesacast BBB The twenty-fourth season of the show features a videocast as a new addition Every day of the week, Mesacast BBB will bring together a team of influencers and TV hosts to discuss the happenings in the most watched house in Brazil Simultaneously aired on Globoplay and Multishow, the show is hosted by Ana Clara, Nany People, Vitor DiCastro, Jojo Todynho, Ed Gama, Mari Gonzalez, Henrique Lopes, Thamirys Borsan, Guto TV, and Pequena Lo.

Final prize change throughout the season Just like the previous season, the grand prize will be undetermined until the end of the season but this time, the prize starts at R$0 and increases over the weeks through the evicted housemates spinning a roulette wheel with different values.

Revised voting system Starting this season, several changes were made regarding the public vote. In addition to having unlimited votes online, named "Fan Vote", the viewers would have the option to vote only once on a separate platform, using their CPF, where they would only be allowed to cast one vote per round. Each of these systems would have a weighted average of 50% in the final result of the vote.

During the first portion of the game, viewers would vote to save nominees from eviction, where the housemate receiving the fewest votes to save would be evicted each round. However, in the second phase of the show, the "vote to evict" voting system would be brought back like the previous seasons.

Three groups The dynamics of the season followed the model introduced in Big Brother Brasil 20, mixing housemates into two groups. In addition to the camarote (celebrity) and pipoca (civilian) groups, the puxadinho (annex) also entered as part of the cast.

Expanded HoH privileges Along with the typical duties of the Head of Household, the HoH will allow in "Control Center" extra Monster Punishment taps to be triggered, albeit in a limited way.

Through the "HoH Pursuer" function, he will be able to find out who was the housemate who most tried to put him on the eviction. Finally, every week, the public will choose an emoji in the "HoH Poll" to define leadership performance: doubtful, hidden, alert, difficult, lucky, bold or ninja.

Larger cast In addition to the 18 housemates selected by production, an additional 14 (later 13) potential housemates were revealed a day before the show's premiere. Viewers were asked to vote two of them (1 man and 1 woman) into the game, while another 6 would be selected by the housemates already in the House during premiere night. As a result, 26 housemates would participate in the season.

Expanded Power of Immunity powers In addition to the winner of the Power of Immunity competition having the power to grant one housemate safety for the week, they would also be immune from eviction.

Big Sincere In the season, the "Discord Game" gave way to a new note-taking activity: Big Sincere. Shown live every Monday, the dynamic will be carried out only by the protagonists of the week: the HoH, the PoI holder and those nominated for eviction.

The host will ask questions based on the themes drawn by the housemates during the panel. The other housemates remain inside the house and watch on the living room screen. If the named participant is among the protagonists of the week, there is the right to reply.

The HoH's Crosshairs After the result of the HoH's competition, the winner of the competition will perform "The HoH's Crosshairs" twist, handing out a number of wristbands to housemates in the house. The HoH will be required to choose his nomination for eviction among the housemates who received the bracelet.

Joker Power Each week, before the house groceries purchases, an advantage or twist of some kind will be offered to all housemates, who can then bid for it in the Diary Room using their in-game currencies, if they wish so. The results will then be displayed to the whole House, with the housemate who entered the Diary Room and bid for the advantage first being the winner, in the event of a tie. The housemates are allowed to share, omit or lie regarding any details related to the bid.

Starting this season, through the "Lose and Win" twist, the housemates will enter the Diary Room with the amount of bids they have accumulated, but the value will change unpredictably. Initially, there will be a quick game of luck, the result of which may be the addition or loss of stakes. After that, knowing the new balance, they can decide if they want to participate in the auction.
