Big Brother Brazil 17 is the seventeenth season of Big Brother Brazil.
Project DNA - Different from the American version, this season features two pairs of twins entering the house on Day 1 before the rest of the cast. Unbeknownst to the twins, the audience will vote for one twin of each pair to remain in the game, while the other twin will be evicted.
Multiple HOHs - Similar to last season, it is possible for there to be more than one HOH within a week. Only one of the HOHs will be granted immunity, while the other one will recieve a cash prize but still be eligible for nominations and evictions.
Big Phone - Similar to previous seasons, whoever answers the Big Phone will either receive the power to nominate someone secretly or will be automatically nominated themselves.
Week 2 - At the beginning of the week, Marinalva was named a have and Rômulo was named a have-not. However, each group had to vote one member of each group to go to the other side. Marinalva was voted to be a have-not by the haves and Rômulo was voted to be a have by the have-nots.
Week 3 - Ieda was randomly selected to pick one haves to be a have-not and one have-nots to be a have. She chose Elis, originally a have-not, to be a have and Ilmar, originally a have, to be a have-not.
Week 4 - Marinalva was randomly selected to pick one haves to be a have-not and one have-nots to be a have. She chose Elis, originally a have-not, to be a have and Rômulo, originally a have, to be a have-not.
On the first day, the two pairs of twins Antônio & Manoel Rafaski and Emilly & Mayla Araújo entered the house. Unbeknownst to the twins until later, Brazil would be voting for one twin of each pair to stay in the game while the other twin would be evicted. In the end, Brazil chose to save Manoel and Emilly, thus eliminating Antônio and Mayla.
On Day 2, the remaining thirteen housemates entered the house. Antônio, Emilly, Manoel and Mayla were forced to sit out of the first HOH competition and were also allowed to chose one other housemate to sit out with them. They chose Daniel. The remaining housemates paired up and went along to compete in the first endurance competition. After roughly two hours, Mayara and Vivian came out on top. After discussing it amongst themselves, Mayara remained immune while Vivian took the cash prize without immunity. Later on within the week, Roberta won an immunity challenge while Daniel and Marinalva won the Power of Immunity and chose to save Luiz Felipe. The nominations came after Antônio and Mayla were evicted and thus Emilly and Manoel were given immunity from the vote. Vivian and Mayara chose to nominate Marcos for eviction while Gabriela Flor received a majority of the house vote. At the eviction ceremony, Gabriela received 59% of the vote to evict from Brazil while Marcos only received 41% and stayed in the game.
