Prizes
The HouseGuests will be competing for the main prize of $500,000.

Twists
Changes to the main format known as twists occur during the course of the season that will impact the lives of the HouseGuests during their time in the House. The twists for this season center around the theme of consequences where the HouseGuests will face consequences for every move they make. The overall main twist is being billed by the program as "The Summer of Consequences" for this reason.

Den of Temptation
During the first three weeks of the season, the viewing public will vote for a HouseGuest of their choice to secretly enter a room called the Den of Temptation. The temptation inside the den could provide an advantage in the game but will come with a consequence that may affect one or more HouseGuests. The public's chosen HouseGuest can chose to accept the temptation or reject it completely. Each HouseGuest can only be chosen to enter the den once during their time in the House. The results of the vote and the HouseGuest decision will be shown during the Sunday primetime episode.

Temptation Competition
Due to Britney accepting the final temptation, the "Temptation Competition" was unleashed for the next 3 weeks. Prior to nominations, HouseGuests (except for the current Head of Household) would be able to decide if they wanted to compete in this competition or not. The winner of the "Temptation Competition" would receive immunity for the week, however, the HouseGuest that finishes last in the competition would be automatically nominated as a 3rd nominee.

Have-Nots
This season, the Have-Nots for the week were offered a temptation. On the wall of the Have-Not room, there were two available spikes. Inside one spike is a Have-Not Escape which would allow its holder to leave the Have-Not Room and become a Have for the week. However, the other held a Have-Not Extension, making the holder a Have-Not for an extra week. One Have-Not per week could go to the Diary Room to claim the key to unlock a spike.
