Twists

 * All Winners Cast: This season had an all-winner cast, in which each of the 21 winners in franchise history were invited back to play again in the "most intense all-star season in franchise history."


 * Traditional Gameplay Format: In order to most accurately capture the abilities and gameplay of all of the franchise's winners, this season has a traditional gameplay format in which no twists will be added to the game, and all weeks will operate under standard procedures, as in Big Brother 21.
 * Expanded Season Length: This season has an expanded season length and will take place over the course of 50 in-game days. This is the greatest number of days in a single season in franchise history, with 20 more days than the standard 30 day format employed since Big Brother 13.
 * Expanded Jury: To honor the legacy of each of the franchise's winners, all of them will play a part in crowning the franchise's first-ever two-time winner, with the season including every single evicted houseguest as a juror, for a total of 19 jurors casting their votes for who they want to see win the season.
