This competition is called "Tag! You're It!" and here is how it works:
The player who won the mystery power, Sandy, is the first tagger.
The tagger will have one minute to tag someone left in the game. Once you become the tagger, you are ineligible to become HoH.
If the tagger does not reveal who they are tagging, then it will go to Chatzy and the tag will be randomized.
We will tag until there is only one person left. That person will become the first Head of Household of the season!
