The HouseGuest who does not collect a folder suffers a punishment. Angela was the winner and Kaycee was the loser.
• Safety Competition – Part 2 ("HouseGuest CAPTCHA"):^{[lower-alpha 1]} The HouseGuests must collect block letters from the pit below their tether which is constantly raising and lowering. Each HouseGuest must collect the correct letters and be the first one to spell "HouseGuest" on their platform.

Swaggy C was the winner and Sam was the loser.
• Safety Competition – Part 3 ("Surfing the BB Web"): ^{[lower-alpha 2]} The winners of part 1 and part 2 faced off in this competition and must "surf" the web.

Following the competitions Julie informed Swaggy C that, of the four original groups that moved into the Big Brother House, he must keep two of the groups safe. The punishments for the two losing HouseGuests were revealed. Kaycee received the "Pinwheel of Doom" punishment and is forced to wear a pinwheel unitard. Whenever the pinwheel spins, she must stay in the room that she is currently in until it stops spinning. Sam is forced to occasionally play the game as a robot; when the words "Robot online" are announced, she plays the game as a robot, but when the words "Robot offline" are announced, she plays the game as a human. Both punishments are in effect until the first live eviction. Swaggy C chose to keep groups 3 and 4 safe from eviction.

• Head of Household ("Microchip Mayhem"): ^{[lower-alpha 1]} When the competition starts HouseGuests must cross their beam and collect a "deletion dot". Once they have collected one they must cross back, place it inside another HouseGuests' tube, and repeat. When a HouseGuest has 10 deletion dots inside their tube, they are eliminated from the competition. Tyler was the winner and became the first HoH of the season.

On Day 5, Tyler nominated Sam and Steve for eviction.

Following nominations, Sam has a one on one conversation with the other HouseGuests. As the HoH, Tyler was forced to choose the first four Have-Nots^[32] of the season. Kaitlyn volunteered and Tyler chose Brett, Scottie, and Winston to be the remaining Have-Nots. Each week in the new BB App Store the most trending HouseGuest will receive a power to help them in the Big Brother game. However, the least trending HouseGuest each week will receive a punishment. Each HouseGuest may only receive a power in the BB App Store once. Faysal was the least trending HouseGuest and received the Hamazon punishment; throughout the week Hamazon will deliver a fresh plate of ham, which Faysal must eat in full. Meanwhile, Sam was the top trending HouseGuest and received Bonus Life power, this gives Sam or a HouseGuest of her choice the chance to return to the game if evicted. The power is only good through the first four evictions and if Samantha does not use it by the third eviction, then the fourth evicted HouseGuest automatically has the chance to return to the game.

The HouseGuests begin speculating who received the Power App, as Faysal receives non-stop deliveries of Hamazon Swine.

JC, Kaycee, and Tyler celebrated making it to the final three. Former Big Brother competitor Jeff Schroeder entered the house and the four looked back on the summer, highlighting their favorite moments.

Kaycee was the winner with a time of 18 minutes and 55 seconds.

Former Big Brother HouseGuest Dr. Will Kirby then hosted the Jury Round Table, interviewing the Jury on who they think should win and why.

If they answer correctly, they gain a point. The HouseGuest with the most points after eight rounds became the final HoH of the season. Kaycee and Tyler tied with six points, each sending the competition to a tiebreaker. Julie asked the competitors a question to which the answer was a number. The HouseGuest closest to the number without going over, or the closest to the number if both went over, would become the winner. Kaycee was the winner and was crowned the final HoH of the season.
