One at a time, a HouseGuest would take a card and state which HouseGuest they felt the card best described; they would then take another card and do the same. The wheel would then be spun, and the HouseGuest whose name the wheel landed on had to eliminate one of the two selected HouseGuests from the game.

Roddy Mancuso was the winner of the competition after he won the tie-breaker round. On Day 21, Roddy chose to nominate Amy Crews and Marcellas for eviction, stating that Amy was his main target.

The HouseGuests must answer the questions by holding up the paddle with the name of the HouseGuest they believe was the correct answer.

Lori chose to give up $50,000 while Tonya, Amy and Eric gave up $250,000, thus eliminating Lori permanently since she didn't give up as much money as Tonya, Amy, and Eric. Since Tonya, Amy and Eric were caught in a three way tie, they were asked a tiebreaker question, which was "Of the remaining 42 days in the game, how many days would you be willing to eat only PB&J?" Tonya said she would go on the PB&J diet for 21 days while Amy and Eric said they would go on the PB&J diet for the remaining 42 days, thus eliminating Tonya permanently as she said she said she would go the least amount of days only eating PB&J.
