They must put the names of the four evicted HouseGuests that fit the category onto their board and then hit their buzzer. If they are correct, a laser "carves" their faces into "Mount Evictus", if they are incorrect, they must attempt to correct it. The HouseGuest to do this with the fastest time became the winner. 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.

• Part 3: ("Jury Oddcasts") Kaycee and Tyler are shown "oddcasts" of Jury members mentioning facts of their time in the house. They must decide if the oddcast is right or wrong. 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.

On Day 99, as HoH Kaycee cast the sole vote to evict JC from the Big Brother house. JC became the 15th and final HouseGuest to be evicted from the Big Brother House and joined the Jury as the ninth and final member. The Jury members then had a chance to ask Kaycee and Tyler questions. The Jury members then voted on who they think should win Big Brother. Julie then asked some of the former HouseGuests a few final questions, which involved Swaggy C proposing to Bayleigh. Later on Day 99, Kaycee Clark was declared the winner of Big Brother 20, by a final Jury vote of 5-4, against Tyler Crispen. Tyler was also subsequently crowned America's Favorite HouseGuest.
