Every day, an HOH will be determined by a vote. The highest vote earner after 24 hours will be HOH. Each HOH competition will have one randomly selected competitor with an "advantage", they start with a plus one vote to win the competition. A random pick will decide the nominees. The HOH and the nominees, plus 3 randomly picked members will compete for POV, and a 24 hour vote will decide the POV also. Weather or not POV is used, and who it's on, will be random. Finally, a third 24 hour vote will be to evict one member from the house.
