- Co-Head of Households: Two player will become Head of Household for the week in the HOH competition, and they will both nominate one player for eviction. However, whoever does better in the veto competition will be responsible of renominating a nominee, if veto is used, or breaking the tie vote. This occurred for the first six weeks of the game.
- BB Open Door: For the first six weeks of the game, America will be voting whether to open the doors to the Big Brother House. They must vote for a week for the doors to open, but if the doors are not opened by the sixth week then the door will automatically open. A game-changing twist will be released into the game depending on the week the doors are opened.
- The Intruders: America had opened the Big Brother door in Week 1, which has allowed for Intruders, Jessica Graf and Scottie Salton, to break into the Big Brother House. Two players from Big Brother (US) would become sim like and join the game of Big Brother.
