On Day 1, the fourteen HouseGuests entered the house for a second chance at winning the game. Following their entrance, HouseGuests competed in the "Falling Stars" Head of Household competition. For this competition, HouseGuests competed in two groups. One group, consisting of seven HouseGuests, stood on a spinning platform, while the other group threw an over-sized boulder at them in an attempt to knock them off of the platform. When only one remained on the platform, the groups switched places. The process was then repeated until only one remained from the second group. This competition resulted in two people winning the title of Head of Household, those being the two people not to be knocked off; Janelle and Jase became joint Head of Household. They learned that if they failed to agree on whom to nominate, then they would become the nominees themselves. Due to Janelle's position of power and their large numbers, Howie, James, Janelle, and Kaysar became quick targets for the others. This led Alison and Danielle to come up with a plan to evict Janelle from the house, in which they wanted Jase to disagree with her nominations and thus nominating both himself and Janelle; this would ensure Janelle's eviction. Despite this plan, Jase and the "Season Six" alliance later discussed the plan with one another, and he agreed to help them out in the game. On Day 3, Jase and Janelle chose to nominate Alison and Danielle for eviction. This made it the first time Danielle had been nominated for eviction, as she had never been nominated in her previous season. Following the nominations, both Janelle and Jase expressed a difference of opinion as to who should be evicted; Jase wanted Danielle to go, while Janelle wanted Alison evicted. When picking players for the Power of Veto competition, the HouseGuests learned of the new twist, in which the three players selected to play would now be randomly selected, as opposed to the Head of Household and nominees deciding. This prevented the backdooring strategy that had been started by Nakomis in her initial season, as all HouseGuests were eligible to compete for the Power of Veto. Kaysar and George were selected to play, while Mike was selected to host. On Day 5, HouseGuests competed in the "One Man's Trash Is Another Man's Veto" Power of Veto competition. On Day 7, Janelle made the decision to leave Alison and Danielle on the block. Following Alison's eviction, HouseGuests competed in the "Alison Rules" Head of Household competition. The HouseGuests had to attempt to answer each question the same way as Alison, and failure to do so resulted in their elimination. Kaysar was the winner of this competition. On Day 12, HouseGuests competed in the "Slop 'Til You Drop" food competition. The team who had the most rats at the end of the competition were the winners, while the losing team would be on Big Brother Slop for the week. The team of Danielle, Howie, James, Janelle, Marcellas, and Nakomis lost the competition. That same day, Kaysar chose to nominate Diane and Nakomis for eviction, with Nakomis being his target. In doing so, Kaysar made a deal with Mike and Will for them to take out floaters in the game rather than Kaysar's alliance. When picking players for the Power of Veto competition, Will, Erika, and James were selected to compete; George was selected to host. On Day 13, HouseGuests competed in the "Big Brother Golf Classic" Power of Veto competition. On Day 18, Nakomis became the second HouseGuest to be evicted from the house in a vote of eight to two. Following Nakomis' eviction, HouseGuests competed in the "Pay Attention" Head of Household competition. On Day 19, HouseGuests competed in the "Balanced Diet" food competition. When picking players for the Power of Veto, Jase, Mike, and Kaysar were selected compete; Janelle was selected to host. On Day 20, HouseGuests competed in the "How Bad Do You Want It?" Power of Veto competition. Shortly before the Power of Veto ceremony, Jase found out he was a potential replacement nominee and began throwing things around the backyard and engaging in numerous verbal arguments. On Day 22, George chose to use the Power of Veto to remove himself from the block, with Jase being nominated as the replacement nominee. On Day 25, Jase became the third HouseGuest to be evicted from the house in a unanimous vote of nine to zero. Following Jase's eviction, HouseGuests competed in the "Define & Dismiss" Head of Household competition. Janelle was the winner, making her the first person to have Head of Household twice this season. On Day 26, HouseGuests competed in the "Food Fight" food competition. Later that day, Janelle chose to nominate Erika and Mike for eviction, hoping to eliminate a "floater" from the game. On Day 27, HouseGuests competed in the "Torture Test" Power of Veto competition. Following his win, Mike kicked a pair of glass goggles, believing them to be plastic, and cut his foot open; the wound required stitches, though did not impact the game in any form. On Day 28, HouseGuests competed in the "Pit Stop" luxury competition. This decision upset numerous HouseGuests, such as Marcellas, Danielle, and James, and led to Danielle, James, Mike, and Will forming the "Legion of Doom" alliance with the hope of evicting Janelle. On Day 32, Diane became the fourth HouseGuest to be evicted from the house in a vote of seven to one. Following Diane's eviction, HouseGuests competed in the "Caught In a Web" endurance Head of Household competition. Danielle was the winner of the competition, making it the first time that someone outside of the "Season Six" alliance won; James won the right to nullify an eviction vote, Mike won $10,000, and Marcellas won a slop pass. Due to the endurance Head of Household competition, there was no food competition this week. On Day 33, Danielle chose to nominate James and Janelle for eviction, with Janelle being her main target. When picking players for the Power of Veto competition, Will, Marcellas, and Mike were selected to play; Erika was selected to host the competition. On Day 34, HouseGuests competed in the "Grave Mistakes" Power of Veto competition. On Day 36, Janelle chose to use the Power of Veto to remove herself from the block, with Kaysar being nominated in her place. For this week's eviction, James chose to use the power he had earned during the Head of Household competition and nullified Janelle's vote. On Day 39, Kaysar became the fifth HouseGuest to be evicted from the house in a vote of five to one. Following Kaysar's eviction, HouseGuests competed in "The Ghost of Big Brother Past" Head of Household competition. Following the Head of Household competition, the HouseGuests learned that a new special power could impact the game, and that the first HouseGuest to correctly guess a secret phrase would be the winner. To solve the phrase, they were given their first hint, which was a sheep. Following numerous complaints of equipment malfunctions, it was decided that a new competition would be held. That night, HouseGuests competed in a new version of the competition, in which they answered using a movable block; Janelle became the new Head of Household for the third time this season. On Day 40, HouseGuests competed in the "Big Brother Bakery" food competition. HouseGuests were later given their second clue for the secret power, which was an over-sized thread and needle. When picking players for the Power of Veto competition, Will, Marcellas, and James were selected to play; Janelle was not able to compete as she had given up the right to play in the previous Power of Veto competition. On Day 41, HouseGuests competed in the "Anything You Can Do, I Can Do Veto" Power of Veto competition. The competing HouseGuests wagered how quickly they could perform a task, and failure to do so resulted in their elimination. Danielle was the winner of the Power of Veto. On Day 43, Danielle chose to use the Power of Veto to remove herself from the block, with Marcellas being nominated in her place. HouseGuests were later given the third and final clue, which was a figure of a Grim Reaper entering the house. It was later revealed that Mike had won the Coup d'État, which he could use at any of the next three evictions. He could overthrow the HoH, and nominate two of his own HouseGuests for eviction; the HoH and PoV winner could not be nominated. On Day 46, Marcellas became the sixth HouseGuest to be evicted from the house in a unanimous vote of six to zero. He became the first member of the Jury of Seven. Following Marcellas's eviction, HouseGuests competed in the "Prom Night" Head of Household competition. Immediately following this, the HouseGuests learned that it was a Double Eviction Week, and that George was required to make his nominations on the spot. He chose to nominate Erika and James for eviction. When picking players for the Power of Veto, Howie, Danielle, and Will were selected to compete; Janelle was selected to host the competition. That same night, HouseGuests competed in the "Gnome Is Where the Veto Is" Power of Veto competition. James chose to remove himself from the block, with Howie being nominated in his place.

On Day 57, Janelle chose to use the Power of Veto to remove herself from the block, with Danielle being nominated in her place. On Day 60, Danielle became the ninth HouseGuest to be evicted in a vote of three to zero. HouseGuests then began competing in the Big Brother Fast Forward week, in which the events of an entire week happened within an hour, meaning that two HouseGuests would be evicted that night. The HouseGuests then competed in the "Battle of the Sexes" Head of Household competition. Janelle was immediately required to make her nominations, and she nominated Erika and George for eviction. The HouseGuests then competed in the "I'm Knots About You" Power of Veto competition. During the competition, Will broke his left thumb in an attempt to get his Veto symbol.
