Twists

 * Returnees: For this season, the winner and runner-up of Big Brother 17, Eli Ottawa and Rachel Ottawa, respectively, returned to compete.
 * Next of Kin: For this season, houseguests entered the game with a Next of Kin pair, with its impacts lasting until the final five. Whenever a houseguest's Next of Kin won HOH, they would become immune. If a HOH's Next of Kin was already evicted, no one would become immune during their reign. For this season, every week was a double eviction. HOHs nominated three houseguests for eviction, with houseguests voting to evict one of the three post-veto nominees. The two post-veto nominees with the most votes to evict were then evicted.
 * Saved by Next of Kin: Houseguests also had the opportunity to walk from the game if their Next of Kin was evicted, saving their Next of Kin and giving them immunity until the final five.
 * Week 4 Reversion: In Week 4, there were only two final nominees for the week, and the veto winner was obligated to take one of the three initial nominees off of the block.
 * Additional Pre-Existing Relationships: In addition to the Next of Kin pairs, several additional pre-existing relationships were present in the cast. Duckie Holly and Ramona Olvida are twin sisters, making them the aunts of Monti Olvia and Tre Holly, respectively. Rachel Ottawa and Marlow Ottawa are married, meeting through Eli following Big Brother 17. Luisa Robayo, Hermes Robayo, Ernesto Sans Royal, and Rapture Torren are all former roommates.
 * Relatives of Previous Houseguests: Several of the season's houseguests are direct relatives of former houseguests. Gustavo Perez and Miranda Perez are the parents of Big Brother 19 houseguest of Alex Perez. Selena Mercel is the mother of Big Brother 12 houseguest Marisol Patron, and the wife of Josef Patron. Additionally, Angela Talvera Patron is the mother of Big Brother 12 houseguest Claudio Patron, and the wife of Carlos Patron. Flavio Renegade and Kendall Renegade are the grandfather and father of Big Brother 5 and Big Brother 6 houseguest Adie Ngolo, respectively.
 * The Bloodlands: For this season, the Bloodlands twist returned. Evicted houseguests competed in a weekly triathlon competition, the winner of which would get to stay in the Bloodlands and the losers of which would be permanently evicted. Twice throughout the season, houseguests were granted re-entry from winning the competitions. The returning houseguests were each granted a week of immunity.
