Twelve new HouseGuests enter the Big Brother house: Scott, Morgan, Shane, Neeley, Shelby, Cornbread, Kryssie, Whitney, Justin, Alex, Monte and Danielle. Jason, from Big Brother 17 was voted into the House by America as the thirteenth HouseGuest over Jozea from Big Brother 18.

Days 8-15 Who will be the next person to be evicted? Shortly after the eviction, the HouseGuests are instructed to go to the backyard for the next Head of Household competition. Two days later, the HouseGuests are informed of America's Care Package, where a HouseGuest will receive a special predetermined power from America.

Days 15-22 Whoever wins America's Care Package this week will have the power of choosing the type of Veto to be played. The winner will have the choice of the Diamond Power of Veto, which would allow the holder to veto a nominee and also choose the replacement nominee, the Boomerang Power of Veto, which allows the holder to veto both of the nominees on the block, and the Double Power of Veto, which puts two vetoes up for grabs, meaning that there would be two "Power of Veto" holders.

Days 22-29 The winner of this weeks Care Package will become "The Safety Servant", earning immunity for the week, provided they follow commands from Big Brother.

Days 29-36 Eliminate Three Eviction Votes: The winner of America's Care Package this week can prevent three HouseGuests of their choice from voting in that week's eviction.

Days 36-43 The winner of this weeks Care Package automatically becomes Co-Head of Household, earning immunity and the right to choose one of the two nominees.

During this week's double eviction, the HouseGuests will not compete in a veto competition; instead, the winner of this Care Package will receive the veto and immunity from nomination.

Days 43-50 For this week's Head-of-Household competition, houseguests have to place four mirrors on stands and adjust them to direct a laser light into a target. The houseguest with the fastest time wins.

The Final Four Challenge: Whoever wins the Care Package this week earns the opportunity to automatically advance to the final four provided they complete a special challenge.

During Week 9, there is no Veto competition or eviction vote. Instead, the two nominees will compete in a sudden death competition, with the loser being evicted.

The Grand Finale. America's Winner: For the first time since Big Brother 1, the viewers will vote for the winner among the 3 finalists, meaning that there will be no jury of evicted houseguests. Who will America choose as the grand prize winner of $250,000?
