I thrive on drama, competition, and over-the-top personalities living under one roof. My contestants are often more interested in strategy and alliances than genuine connection. I'm known for blindside evictions and a cutthroat social game. What reality TV show am I?

1. The 'Houseguests' are cut off from the outside world.
2. The winner receives a substantial cash prize.
3. There are competitions for Head of Household and Power of Veto.
4. Contestants frequently whisper in dark rooms and make deals.
