Twists & Changes

 * Joint Houseguest : On Day 1, Emily & Noah entered the house separately to unknowingly find each other. The two siblings would compete in competitions every other week beginning with Emily and would only get to share one vote.
 * The Night Shift: On day 1, houseguests were informed by Julie that they all needed to get into four teams of four. Teams were then decided, and the houseguests were informed that they were going to all individually vote for one team to become safe from the first eviction, while also not being eligible for the first HOH. This left 3 teams to compete in the first part of their HOH competition. In this HOH, the winning team earns safety, and will also send one of the two losing teams into the "Power Charge". The team to be chosen to go into the power charge will all compete against each other, where the first person to finish will become the first HOH of the season, and the last person to finish will be evicted. Teams did not carry on in the remainder of the season.
 * Battle Backs: On day 23, the first four evicted houseguests competed in the "Battle Back Showdown". This was a competition played out by all four evictee's, where the winner would earn their way back into the game. The winner also received a secret power that was chosen by America. America voted all week prior to the battle back competition to choose what power the returner would receive, and they chose to reward the returner with the "Coup d'etat".
 * Coup d'etat: This power allowed the returner of the Battle Back to halt one eviction of their choosing, overthrow the HOH, and re-nominate two houseguests. They can keep one or both nominations the same if wanted. This power expired within three weeks of activation.
 * Double Eviction: On day 30, Julie informed the houseguests that it was double eviction night. For the first time in BBSD history, houseguests played two weeks worth of competitions, and two evictions all in one night!
