Big Brother 12

Big Brother 12 was the twelfth overall season of Mateo's Big Brother Series.

Twists

• 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. America will have the chance to open the door for the first five weeks of the game, in doing so, they will release a game changing twist upon the house. If they do not open the door in the first five weeks, the doors will open in the six week.
