Big Brother 5

Twists

 * Returning Players: Four flops from past seasons are returning!
 * Teams: HouseGuests divided into teams of four with one returning HouseGuest on each team. Each week, the Head of Household's teammates were safe from eviction. The Teams Twist ended on Day 37 along with the Roadkill Competition.
 * Roadkill Competition: Each week the HouseGuests competed in the Roadkill Competition. The winner of this competition was privately informed of their victory and received the power to name a third nominee for eviction anonymously. If the Power of Veto winner took the "Roadkill Nominee" off of the block, the Roadkill winner would secretly name a replacement nominee. The Roadkill Competition ended on Day 37 along with the Teams Twist.
 * America's Care Package: At the beginning of Week 6, Moonious introduced America's Care Package. This twist allowed the viewers to vote for one HouseGuest to receive a special advantage within the game each week.
 * Jury Re-Entry Competition: Following Week 9's eviction, the five jurors and the remaining HouseGuests competed in an endurance Head of Household competition. The last juror standing won the right to return to the house, and the last HouseGuest standing (jurors included) became the next Head of Household.
