a second consecutive week, except for the final week or other stated circumstances. Introduced in season three is the Power of Veto, where any HouseGuests compete for the right to replace any nominated HouseGuest from the eviction, which continues until three HouseGuests remain. Introduced in season seven are Have-Not competitions, where losing HouseGuests are penalized with a "Have-Not" diet by eating slop and sleep in a special bedroom for the remainder of the week. At the end of the week, all HouseGuests except for three (the Head of Household and the two nominees) cast a vote, one-by-one, privately inside the "Diary Room" (also called Confession room in other shows), to determine which of the two nominees should be evicted; the HouseGuest receiving a majority of the eligible HouseGuest's votes is evicted during a live episode; if there is a tie in the voting, the reigning Head of Household then casts the deciding vote to resolve a tie.

The "Double Eviction Week" has become a staple of the show, particularly in the penultimate week featuring the Final 5 and Final 4 evictions. Another variation of the Double Eviction was introduced in season seven with the "Double Eviction Night" where the events of the week occur over the course of the Live Eviction episode, with the event also becoming a staple of the show. The 22nd season, introduced the "Triple Eviction Night", where two weeks worth of game events are played within an extended Live Eviction episode so that three HouseGuests are evicted. The "Triple Eviction Night" was previously used on Big Brother Canada with a different format - where a single live round was played, with three Nominees and Two HouseGuests being evicted within a single round. Another variant is "Eviction Competition" (such as season
