Big Brother 15 (American season)
The show's format remained the same from previous seasons of the show. A group of contestants, known as "HouseGuests", compete to win the series by voting each other off. They must be the last HouseGuest remaining. Each week, one HouseGuest, known as the Head of Household, must nominate two of their HouseGuests for eviction. The winner of the Power of Veto can remove one of the nominees from the block. The Head of Household must nominate another HouseGuest as a replacement. The HouseGuests then vote to evict one of them, the nominee with the most votes are removed from the show. When only two HouseGuests remain, the last seven evicted HouseGuests, known as the Jury of Seven, would decide which of them would win the $500,000 prize. A HouseGuest can be expelled from the show for not following rules.
