The game

Final prize change throughout the season

After twelve years without adjustments to the maximum prize awarded to the winner of the reality show, the value of the final prize will be increased in this edition. Since Big Brother Brasil 10, that value was R$ 1.5 million, an amount that has sparked discussion in recent seasons due to the inflationary lag and the increasing success of previous alumni leading to future houseguests playing relatively risk-free games with a post-show career in mind, rather than winning the game itself.
This season was have the biggest prize in the history of the reality show. Surpassed by the following season. The value of the final award is undefined. This is because it may increase during the course of the season, according to the performance of the housemates.
Each week, on Tuesday elimination nights, three housemates will be chosen by random drawn to try to guess who will be evicted, with a cash value being added to the final prize for each correct answer.

Super HoH

Along with its regular powers, the HoH would also be tasked with splitting their housemates into Haves and Have-Nots as well as choosing what and how much each group would be eating.
Starting this season, the HoH will be able to enjoy a great "Control Center", right from their exclusive room, in a limited and predetermined way, with several commands that allow a privileged point of view of the game.
The HoH will also be able to watch what happens in the rest of the House with audio, find out the total number of votes they received so far; and the ability to wake up housemates at any time they want.
Roles have limited access, but make the HoH post even more valuable and strategic in the game.

Withdrawal Button

Since season twenty-two, there has been an opt-out button. Thus, the housemate who wants to give up the game can just press the button, without having to resort to the Diary Room or the production of the program and leave the program immediately.
The item will be visible to all housemates, in the room of the house. However, the button will be protected in an illuminated box, closed by a hatch, and can only be activated when indicated by the green light. The button will work at certain times, being unavailable and with red light during parties, from 9 pm to 9 am, to prevent housemates from pressing it while intoxicated.

#FeedBBB

The theme of the reality show is such that each housemate will use a cellphone to capture moments in the house during a time determined by the production. The cell phone only allows them to post photos and videos to #FeedBBB, and see what other housemates say about each other. It does not allow contact with the outside world.
Since the season twenty-one, #FeedBBB introduced "Arrow", an app akin to Tinder, which housemates used to pick out their love interests in the house. The "HoH Podcast" is recorded weekly and published on the GShow website. The housemates can see when it is being recorded but do not hear the content.
In addition to the novelty called "Anonymous Torpedo" has been added to the platform since the twenty-second season, which can further influence the house's relationships. The function allows housemates to send anonymous messages, with no declared author, to other confined people, which are published on the screen in the room for everyone to see.

Selective Collection

The season, the housemates will be rewarded according their waste management in order to promote sustainability. Each week, they will earn Estalecas – the House currency – from their selective collection based on a ranking established by production alongside TV Globo's Environmental Management area.

Evicted's Message

For the first time in the show's history, the evicted housemate can leave a video message for someone still in the running.
The video will be addressed and displayed on the home screen, in front of all those inside the House. The evicted housemates will be able to leave an advice, warning, or even doubtful information in order to harm a confined person, according to their personal strategies.

Glass House

On January 10, 2023, four additional housemates entered the Glass house where the public voted for two of them to move into the main House.
Twist introduced in Big Brother Brasil 9, re-used in Big Brother Brasil 11, Big Brother Brasil 13, Big Brother Brasil 20 and Big Brother Brasil 22.

Duos Twist

During Week 1, the 22 housemates were split into duos where they would compete in competitions and could also be nominated together. The duos were chosen by a public vote held a couple days before the premiere, in which each Civilian was paired with a Celebrity, with the exception of the two Glass House contestants selected by the public to enter.
Housemates entered the House on Day 1 handcuffed to their duo partners and stayed that way up until Night 3.

Secret Room

The duos split up on Day 9 after the reveal of the first public vote. Has been informed that the chosen duo would move to a Secret Room where there would be a second vote to determine which housemate from the duo would be officially evicted as an individual on Day 11.

Higher Power

The housemate who answered the Big Phone on Day 39, won the "Higher Power", it could overthrow the Head of Household, the House votes, the Big Phone or the Counterattack and replace the nominations. This power could only be used once and within the next eviction.
The twist was based on "Coup d'État" format used US Big Brother, and was used two times before during the 10th season, and re-used in 12nd season.

White Room

On Day 52, two housemates were chosen to enter the White Room, where they would stay until the live HoH competition on Day 53, competing in an endurance competition, that would determine the first nominee of the week. The winner would immediately return to the house with immunity and win a car, while the loser would be automatically nominated, without be eligible to compete for the veto.

Housemate Exchange

On March 13, 2023, a housemate exchange with La Casa de los Famosos was announced. Evicted contestant Key Alves swapped with Dania Méndez from La Casa de los Famosos 3 on Day 59, swap which was originally meant to last a week on both ends. The twist was prematurely interrupted due to a controversy in the BBB house with Dania, where two houseguests were ejected from the game following inappropriate behavior with her.
However, Dania was still in contention for the La Casa de los Famosos prize, while Key had already been evicted from Big Brother Brasil. The choice to make the exchange for a housemate who had already been evicted was made due to the rules of the Brazilian's reality show not to bring outside information into the house.

Repechage Twist

On Week 9, following the double ejection of Antônio and Guimê due to inappropriate behavior with international guest Dania Mendez, it was revealed to the public that two eliminated houseguests would have the chance to return to the game in a repechage action.
The first 9 evicted houseguests - with the exception of Antônio and Guilherme, who were ejected, and Bruno, who chose to walk from the game - joined by the person evicted on Week 9, would be confined into a house for two days, where the public would vote to send two of them back into the game. The two houseguests chosen to return to the game would not be allowed to compete in the next scheduled Head of Household or Power of Immunity competitions.

Vote to Save

On Week 11, the voting system worked the opposite way, with the public voting for save among the nominees as opposed to voting to evict like normal.
