Knockout is a recurring Power of Veto and Head of Household competition.


  • Two people are picked to go up to a podium and they will be asked a question about a picture.
  • The first player to buzz in with the correct answer eliminates their opponent. They then choose the next two to face off.
  • If they answer incorrectly, then they are eliminated and their opponent advances.
  • If nobody buzzes in, they will both be eliminated.
  • The last player standing becomes the new HOH.
