16 All-Star Houseguests entered the house in four groups.

• Head of Household Competition: The first HoH competition was played in two rounds.
  • First Round: Upon entering the house, the move-in groups of four would instantly compete in a competition. In the competition, an item would be shown on a screen in the backyard and HouseGuests would have to find the item in the house. They would then roll a ball through a maze, with the goal of landing the ball in the hole corresponding to the room the item was in. The first two HouseGuests in each heat to complete the puzzle would compete in the second round. Given the live nature of the competition, this competition also had a 4-minute time limit. Should a heat exceed four minutes, then only those who completed the table maze would move to the final round.

In the move-in group of Christmas, Da'Vonne, Dani and Nicole F., only Christmas advanced. Kevin and Ian advanced from the group of them, Tyler and Enzo. Nicole A. advanced from her group of her, Janelle, Keesha and Bayleigh. From the group of Cody, Memphis, David and Kaysar, Cody and Memphis advanced.

• Final Round: The players who made it to the final round competed for one-by-one in a live competition. The HouseGuests would each have to race across a series of pedestals and make it to the other side of the yard, locking in their time with a buzzer. Some of these pedestals were not sturdy. If a HouseGuest fell off a pedestal, they would have to restart. The HouseGuest to complete the course in the fastest time would be the new Head of Household.

Cody completed the course fastest and became the first Head of Household of the season. The other five HouseGuest took an envelope each: Christmas won $5,000 while Ian, Kevin, Memphis and Nicole A. were named the first Have-Nots.

For the next three weeks, the Safety Suite competition opened for any HouseGuest who wishes to compete for safety from the threat of eviction. Each may only participate in one competition and whoever wins will be granted safety for the week, plus another HouseGuest of their choice will also receive safety, but with a punishment.

• Safety Suite Competition ("Don't Miss a Beat"): In this competition, the object was to put together sections of the Twinkle, Twinkle, Little Star remix by pressing seven buttons in the correct order after listening to the whole song. The HouseGuest who completed the task in the fastest time would be declared the winner.

Janelle and Kaysar were the only two HouseGuests to compete. Kaysar beat Janelle and subsequently named her as his +1. Along with her safety, Janelle had to wear a star unitard for her punishment. With two of his potential nominations now immune, Cody decided to put up two people he felt were "outcasts". On Day 2, he nominated Keesha and Kevin for eviction with Keesha as his main target.

Alongside Cody, Keesha and Kevin, Enzo, Ian, and Tyler were drawn for the POV.

• Power of Veto Competition ("Going Bananas"): Contestants had to rock back and forth on a giant banana to earn 90 seconds to stack the most fruit cutouts they can on a stand. To earn more time, you had to get back on the banana and rock back and forth before the timer reaches 0. If the timer reaches zero or they exceed the 30 minutes total time limit, whichever comes first, they earn zero points and are eliminated. In the contest, only Enzo locked in his stack with 18 items.

Enzo chose not to use the veto, keeping Cody's nominations the same.

Cody and Enzo solidified their Final Two alliance, the Root, due to their similar upbringings and play style. Keesha aligned with Janelle and Kaysar, who tried to campaign for her. Keesha herself did a poor job of campaigning while Kevin set himself up in connections with Cody, Da'Vonne, and Nicole A. Ultimately, by a unanimous vote of 13-0, Keesha was the first HouseGuest evicted.

• Head of Household Competition ("A Big Brother Watch Party"): The houseguests watched a short video skit of a dysfunctional family's video chat Big Brother watch party. Then Julie would ask the HouseGuest a series of True or False questions, with an incorrect answer resulting in a HouseGuest's elimination from the competition.

Memphis won the competition after six questions, being the only one to answer the sixth question correctly.

After each week, all of the Have-Nots will each have to name a replacement Have-Not, who can neither be the current Head of Household, nor one of last week's Have-Nots, meaning one cannot be subject to two consecutive weeks of Have-Not restrictions. Memphis chose David, Nicole A. chose Christmas, Nicole F. volunteered for Ian, and Kevin chose Kaysar.

Memphis decided to persuade the rest of the HouseGuests to compete in the Safety Suite Competition as a ploy to guarantee that he has a higher chance in winning the following week. Bayleigh, Christmas, Cody, Da'Vonne, David, Ian, and Kevin swiped their VIP Passes to enter the suite to compete.

• Safety Suite Competition ("Gettin' Tipsy"): Seven houseguests scanned their VIP passes for entry in this week's safety suite competition. The goal is to place all of the drinks on the corresponding tables in the fastest time. All drinks on the red tray go to the red table, while the drinks on the blue tray go to the blue table. This had to be done in such a way that the tables will balance so that no drink falls off.

Christmas completed the task in the shortest amount of time and won immunity, and gave the +1 to Ian. Ian's punishment was revealed as the "BB All-Star Wars". At various points, a voice would come over the loudspeaker instructing Ian to put his costume on and act out various scenes over the rest of the week.

Memphis' allies suggested nominating Janelle and Kaysar, fearing them as a duo. However, Memphis disagreed as the duo was a key piece for him still in the game. At the nomination ceremony, Memphis nominated David and Nicole A.

Following the nomination ceremony, the rest of Memphis' alliance felt that his speech belittled David and came across as ignorant. Tyler pulls David aside to cheer him up stating that if he won the Power of Veto, he would use it on David. Later, Ian, Tyler and Nicole F. were chosen to compete alongside Memphis, David, and Nicole A. in the PoV competition.

• Power of Veto Competition ("All Starry Night"): Houseguests have to stand on a slanted surface and hold a ball steady on a flat surface held out in front of them. Last person to let the ball fall wins the Power of Veto.

After about half an hour, Memphis won the Power of Veto. At the veto meeting, members of his alliance tried to convince Memphis to use the veto to backdoor the duo of Janelle and Kaysar, while they, mostly Janelle, tried to convince him to backdoor Nicole F. However, Memphis decided not to use the veto, leaving his nominations the same.

Nicole A.'s trust with Janelle and Kaysar began to deteriorate as the majority of the house began to convince her that she was being used. Then, by a vote of 10-2, Nicole A. was evicted, with only Enzo and Kevin voting to evict David.

• Head of Household Competition ("Mug Shot"): Each Houseguest must push the mugs to the nearest target possible and get most points as they can. The Houseguest with the fastest time and most points wins HOH.

Tyler won with a score of 12 points, barely surpassing Janelle, who had 11.

Due to Janelle and Kaysar's close ties to Memphis, they talked to Memphis the previous week about an alliance that was forming with Cody, Dani, Nicole F. and Tyler, with no idea that Memphis was in the exact same alliance.

• Safety Suite Competition ("Stealing Safety"): Dani, Enzo, Memphis and Nicole F. all competed in the last safety suite competition. The goal is to get past all of the lasers to open the safety vault and bring the large ball all the way back to the beginning without disrupting a laser beam. If hit, the alarm goes off and the player has to rush back to the start and press the button to reset the alarm. The player who makes it back to beginning and hit their button in the fastest time will be safe for the week.

Enzo completed the task the fastest earning him safety for the week and he then give the +1 to Christmas. Christmas' punishment was "All-Star is Born". Throughout the rest of the week, Christmas would receive "star babies" and must carry them around with her wherever she goes. At the nomination ceremony, Tyler nominated Janelle and Kaysar with Janelle as his target.

Alongside Tyler, Janelle and Kaysar, Bayleigh, Cody, and Memphis were selected to play in the PoV.

• Power Veto Competition: ("Cupcake Clash") HouseGuests competed head-to-head in a randomly drawn tournament to sort out three cupcakes in a Tower of Hanoi pattern. Since there are six players, the fastest of the first round advances to the championship round while the other two winners face head-to-head, with the final two competing in the final round.

Cody won the Power of Veto. With Cody being part of the big alliance, he decided to not use the Power of Veto, feeling like Janelle and Kaysar would come after them given the chance.

With the Committee wanting Janelle out, feeling as if she was a bigger physical threat, they all set their eyes on her on eviction night. On Day 23, Janelle was evicted by a vote of 9-2, receiving two hinky votes from Dani and Enzo in an attempt to spur paranoia.

• Head of Household Competition: ("Carnival Quick Shot") Houseguests are split into two different groups for this competition. Each group compete in each round by getting all three balls in those holes first. The first three HouseGuest to complete the task moves on to the final round, and the first HouseGuest in the final round wins the competition.

David, Da'Vonne, Enzo, Kaysar, Ian and Nicole F. competed in the first round, while Bayleigh, Cody, Christmas, Dani, Kevin and Memphis will compete second.

Following Janelle's eviction, this was Kaysar's first time playing Big Brother without her, and he immediately knew he would be targeted next.

• Head of Household Competition: ("Carnival Quick Shot") Continuing from the live eviction night on Thursday, the competition was played out to reveal the six winners from the first round, who competed in the final round to determine HOH.

The 6 people that advanced to the final round were Cody, Dani, David, Enzo, Kaysar, and Kevin. Enzo managed to pull the HoH win and secure safety for the week. Although Enzo was not part of the Committee, he was heavily affiliated with them, including a side alliance with Cody, Dani and Nicole called the Core Four, they were able to convince him to target Kaysar for the week. At the nomination ceremony, Enzo nominated Kaysar and Kevin, with Kaysar as his official target and Kevin as the pawn.

Alongside Enzo, Kaysar and Kevin, Bayleigh, David, and Tyler were chosen to play in the PoV competition.

• Power of Veto Competition: ("Face the Puppetmaster") HouseGuests had to hold on to four ropes, one for each arm and leg and stay there as the ropes were pulled all around. The last HouseGuest remaining won the competition.

Kevin won the Power of Veto. At the veto ceremony, Enzo briefly thought about nominating Ian as a new target, but decided against it, feeling it was too much of a move. He instead nominated Christmas, who had offered herself as a pawn.

On eviction night, during the two nominee's pleas, Kaysar took shots at the majority group, but mostly Cody, Dani and Nicole. By a unanimous 10-0 vote, Kaysar was evicted.

• Head of Household Competition: ("Filter Faceoff") Houseguests competed in head-to-head rounds and were shown pictures from the Memory Wall, with different filters applied to the Houseguests' faces every round. Julie gave a category and a number and asked whether the amount of photos fitting that category were more, less or exactly the same as stated in the question. If a HouseGuest answered wrong or their opponent got the question correct first, they were eliminated. The winner of each round chose who would compete in the subsequent round, with the last houseguest remaining, winning the competition.

Da'Vonne managed to make it to the final round by winning all of her match-ups, alongside Christmas, who didn't get to answer any questions up to that point. Da'Vonne slipped up at the final question and incorrectly answered, making Christmas the HoH for that week.

On the previous week, Bayleigh approached Christmas and asked who her "untouchable" was, with Da'Vonne as her own untouchable, which startled Christmas. Prior to the nomination ceremony, the houseguests were informed about the newest twist; the Big Brother Basement, which would replace the Safety Suite competition for that week only.

• Special Comeptition: ("BB Basement") Three game-changing powers were hidden in random places inside the Big Brother basement. Houseguests had to search around in complete darkness among trash and other obstacles for power icons that would fit inside one of the three power podiums. Each person who found a power icon and matched it with the correct podium would receive that special power; however, they would not know what power they had received until after the competition was over. All three powers were eligible to be used once over the next three weeks. Christmas, David, and Dani were the winners.

Christmas received the Blocker Power, which allowed her to prevent either herself or another houseguest of her choice from being named the replacement nominee at one of the next three veto meetings. David earned the Disruptor Power, granting him the ability to save one of the nominees selected by the HOH, and making them safe from eviction for the rest of the week. Dani obtained the Replay Power, granting her the power to allow one of the next three outgoing HOHs, herself included if she became HOH, to participate in the next week's HOH competition along with all the other houseguests.

Christmas named Da'Vonne and Bayleigh as her nominations that week.

For the Veto competition, the players picked were Christmas, Bayleigh, Da'Vonne, Nicole, Dani and Ian; Ian however was unwell and sat out of the PoV competition under medical advice.

• Power of Veto Competition: ("Mathcathlon"): Each participating HouseGuest held onto two red buttons until they saw an equation that equals to 13. The HouseGuest who either gave the correct equation last or incorrect equation first was eliminated but would receive a different reward or punishment depending on performance. The last HouseGuests would win the veto.

Christmas won the Veto, while Bayleigh and Nicole were given punishments, and Dani and Da'Vonne won a Never-Not Pass and $5,000, respectively. Christmas decided not to use the Veto, keeping her nominations the same.

Bayleigh was unanimously evicted with a 9-0 vote. Following her eviction, they were informed that the Have-Nots were reset and they will be competing in the Head of Household in conjunction with the Have-Not competition.

• Head of Household Competition ("Power Trip"): HouseGuest had to hang onto a billboard for as long as possible. The first three HouseGuest to fall off would be subjected to "Have-Not" for this week, and the last HouseGuest standing wins.

Ian was voted out of the house in a 5-3 vote, with Da'Vonne, David, and Kevin voting in favor of evicting Tyler, making him the first Jury member.
