Big Brother Brazil 3 is the third season of Big Brother Brazil.
Power of Immunity - There were fourteen Housemates competing for the grand prize, an increase over the two previous seasons. The season lasted 78 days, an increase of one week over the previous season. This season introduced the "Angel Power" or "Power of Immunity".
First vote - At the first round of nominations there were two separate rounds of nominations - one in which males nominated the females, and one in which the females nominated the males. On Day 8 there was a double eviction - with the female and male evictees leaving the House. This Week's HoH Elane could only exercise her powers during the male Nominations round.
Inclusion - The Angel and the Immunized were included for the first time in the program, which would be used in the future in all subsequent editions. The "Angel" was chosen through weekly tests. The angel himself does not gain immunity, but can grant a friend immunity to the Appointment. This immunity is symbolized by a necklace.
Walked from Dilson - The participant Dilson gave up, both due to the constant fights with Joseane and the longing that he felt for the family
Replacement - Harry came into the game replacing Dilson.
