Original, where the housemates live in the house and get to know each other, nominating 2 of each other every or every other week, and the two or more with the most nominations go up for eviction, where the Public Vote by the viewers determines the evictee. After 3 remain, the Public Vote goes for the winner, and the winner receives the prize money.
US, (the US did use the original for one season) the housemates compete in competitions during their time in the house, Hoh for the person who determines the Nominees, the POV who saves a person and then the eviction. The two or three at the end (Idk bc I don't watch the US version) are voted on by all eliminated housemates, and the one with the most votes is the winner of the prize money.
