Big Brother 7

Big Brother 7 was the seventh season of Big Brother: Off The Block. This season premiered on August 30th, 2020 and concluded on October 3rd, 2020. This season's theme was apocalypse which correlated well with the season's main twist, "Absolute Chaos." This twist tested how well the houseguests could adapt throughout the pre-jury phase of the game by introducing a new twist every week. Only the ones who could adapt well enough would survive the "apocalypse." The twists varied each week with some being more severe than others. BritishHali17 ended up winning season 7 against taliadavidson in a unanimous vote of 9-0. PrinceDan2005 won America's Favorite Houseguest.

Development
Development for season 7 began before season six even premiered. Andy was very motivated during the summer so he decided to start working on season 7 with Abby. Andy built the house in a couple of days keeping it under wraps for a while before Abby made the announcement that they were renewing for a season 7. On the 8th of August, 2020, Abby announced to the public that Big Brother: Off the Block would be renewed for their 7th season. Since the house was fully developed by the time of the announcement, all that was left for development was casting.

Casting
The same day that Abby/Andy announced that they were going to renew for a season 7, applications were released also. Abby announced that applications would be open from August 8th, 2020 to August 19th, 2020. (a week after season 6 ended) Once applications closed, all letters were sent out a day after since the casting directors (Andy and Deli) read through apps as they came in. The cast reveal occurred a few days later with the houseguests being quickly moved into the BB7 house.

Twists

 * Absolute Chaos: The absolute chaos twist makes it so that each week of the prejury the twist shakes up the game in a different way from the last, each twist paying an homage to a previous season.
 * Devil's Den: Milky entered the devil’s den after volunteering to go in. He had the opportunity to choose from 4 anonymous options, 2 being advantages and 2 being disadvantages. He chose a disadvantage that made it so that he had to vote publicly the first two weeks.
 * Three Nominees: On week two, Dan had to nominate three people instead of two. The veto winner had to use the veto, and there would not be a renominee. He decided to nominate Ciande, Katniss, and Eyriaza, where Ciande was pulled off the block.
 * Battle Of The Block: On week three, two Head of Households would be crowned and they would each nominate a pair of nominees. The winning pair would be safe from eviction for the week and would also dethrone the HOH that nominated them, leaving the other HOH as the sole Head of Household. Katniss and Ciande won the competition, leaving Winter and Milky on the block.
 * Instant Eviction: During the double on week 3, it was revealed to be an Instant Eviction. The HOH must immediately name two nominees. The nominees will be the sole nominees of the week, because a veto competition would not take place. Ciande won the Instant HOH, and Dan was sent home.
 * Vote Count Not Revealed: The twist was a throwback to season 5, everything about the week was a typical big brother week except the vote count was not revealed, just who received more votes and was evicted.
