Launch night On the night of the Live Launch several members of the public, who have passed through several audition processes, enter the House to become Housemates of the Big Brother House. Once inside the house the Housemates will live together and have no contact with the outside world.
Head of Household (Líder) Except in the first week, after each eviction (
Portuguese:
paredão, a term which literally means "big wall"), housemates compete to become the "Head of Household" (
líder), by winning a weekly physical endurance challenge, based on a specific skill, a general knowledge quiz or, even sometimes through a luck event. The
Líder receives perks such as their own private bedroom, photos or gifts from home, and maid service. The
Líder is awarded immunity from the week's nomination (except in the fifteenth and sixteenth seasons where instead the
Líder won a cash prize) and also has the power to directly nominate one housemate for eviction, in addition, the
Líder is the tiebreaker for the house's nomination vote. Although one housemate normally retains the Leader rewards and responsibilities for the week, exceptions have occurred. In a "double eviction" week, the first
Líder only reigns for a short period (between an hour and three days) while the second
Líder reigns for the rest of the week. When this occurs, the first
Líder is normally not provided the perks awarded in a normal eviction week. Another exception is when two housemates share the
Líder position, such as in the third week of the
sixth season and in the first week of the
seventh season.
Power of Immunity In the
third season, a weekly "Power of Immunity" (
anjo, a term which literally means "angel") is introduced and determined. This housemate may choose any other housemate to protect from facing the eviction. However, in the
seventh season, another selected house mate was given the "Power of Veto" to nullify the saving power. Since the
eighth season, Power of Immunity winner was also given a bad side (called
monstro, a term which literally means "monster"), where that housemate, besides protecting someone from elimination, must "punish" one or more contestants, obliging them to do an unpleasing task or forbidding them to go to the party.
Estaleca or food competition On Sundays, a competition allow the housemates to win food (until the
fourth season) or estalecas (from the
fifth season onwards) for the week. Most competitions are games of skill, although the housemates may work individually, in teams, or as one group. Introduced in the fifth season, the "Estaleca" (Z$) is the official currency of the house. Each contestant has their own
credit card with a set amount of Estalecas. Contestants may use their currency to purchase food for the house. The winners of the week's Estaleca competition earn the right to do all the shopping, choosing what the entire house will eat for the upcoming week. As in the real
stock market, the Estalecas can suffer some
speculative attacks and thus the value of the groceries may inflate or deflate.
Sunday live nominations First the PoI winner and HoH nominate their choices for their respective abilities. Then, each one of the remaining contestants go into the Diary Room, and vote on the contestant they wish to face an elimination match. The highest voted contestant is sent to the elimination match to face the person nominated by the HoH and an audience poll starts (either by telephone,
SMS or
Internet) to pick which of the nominated contestants shall be eliminated. Since the
twenty season, the nominated housemates compete against each other for one last chance to save themselves from eviction. The housemates nominated by the HoH are not eligible to compete and are guaranteed to face Brazil's vote.
Tuesday live eviction On Eviction Night, the poll result is shown and the highest voted housemate is eliminated and evicted from the house. The evicted housemate must to get ready to leave immediately. Once they leave the House they are greeted by the live crowd and the show host.
Live Final and the winner In the Live Final, only two to three housemates remain in the house, after surviving numerous evictions. The public are then asked to vote for their favourite surviving Housemate to win the prize. The winner is announced and the final three surviving housemates leaving the house together, treated to a cheering crowd.
