The game
Rules changes
This season, the Head of Household back to be eligible to compete in the next HoH competition after his leadership, having the chance to be HoH multiple times in a row. Also, he/she gains R$10.000, the Power of No and the right to divide the housemates into two teams for the Food competition. However, for the first time since BBB started, the HoH has no immunity in the nominations, becoming vulnerable to being nominated by the house vote.
You're in control!
Big Brother introduced a new way to give more power to the audience, calling it Você no Controle. Every week, producers pose a question and the public must vote between two options. The voting usually is opened on Friday and finishes on Sunday.

The cast list with the first 13 housemates was unveiled on January 13, 2015.[3] On day 2, two potential competitors (Aline and Julia) entered the house in order to compete by public vote for the 14th housemate's spot.[4]
^Note 1 : Aline and Julia entered the house on Day 2, both already nominated. The audience should vote for one of them to become a full housemate. On day 6, Aline was the winner of the vote, becoming an official housemate, while Julia was evicted from the house. By winning the voting, Aline had immunity on the first nomination.
^Note 2 : By popular vote, the Have-Not group could immunize one of them. They chose Mariza.
^Note 3 : Adrilles and Angélica tied with 4 votes each. Head of Household Rafael broke the tie and decided to nominate Adrilles, so he joined Douglas (HoH's choice) as this week's nominees.
^Note 4 : Luan and Marco tied with 5 votes each. Head of Household Amanda broke the tie and decided to nominate Marco, so he joined Fernando (HoH's choice) as this week's nominees.
^Note 5 : Because of the "You're in control" vote, the Housemates voted in a round of face-to-face voting.
^Note 6 : This week, top 2 vote recipients became the House's Nominees.
^Note 7 : Luan answered the Big Phone and was automatically nominated for eviction.
^Note 8 : Adrilles, Fernando, Mariza and Talita tied with 1 vote each. Adrilles, as Head of Household, broke the tie to determine the second House nominee. He decided to nominate Talita.
^Note 9 : This week the Head of Household made their nomination after the House Vote as a result of "You're in control" vote. Cézar and Luan tied with 2 votes each. HoH Amanda broke the tie and decided to nominate Cézar. Amanda then nominated Luan as her HoH nomination.
^Note 10 : This week, Adrilles' vote counted as two as a result of "You're in control" twist.
^Note 11 : Cézar won the final competition, winning immunity for the final eviction and granting his place in the Finale. Therefore, Amanda and Fernando were automatically nominated for eviction by default.
^Note 12 : For the final, the public will vote for the housemate they want to win Big Brother Brasil 15.
