Big Brother follows a group of contestants, known as HouseGuests, who live inside a custom-built house outfitted with cameras and microphones recording their every move 24 hours a day. The HouseGuests are sequestered with no contact with the outside world. During their stay, the HouseGuests share their thoughts on their day-to-day lives inside the house in a private room known as the Diary Room. Each week, the HouseGuests compete in competitions to win power and safety inside the house. At the start of each week, the HouseGuests compete in a Head of Household (abbreviated as "HOH") competition. The winner of the HoH competition is immune from eviction and selects two HouseGuests to be nominated for eviction. Six HouseGuests are then selected to compete in the Power of Veto (abbreviated as "PoV") competition: the reigning HoH, the nominees, and three other HouseGuests chosen by random draw. The winner of the PoV competition has the right to either revoke the nomination of one of the nominated HouseGuests or leave them as is. If the veto winner uses this power, the HoH must immediately nominate another HouseGuest for eviction. The PoV winner is also immune from being named as the replacement nominee. On eviction night, all HouseGuests vote to evict one of the nominees, though the Head of Household and the nominees are not allowed to vote. This vote is conducted in the privacy of the Diary Room. In the event of a tie, the Head of Household casts the tie-breaking vote. The nominee with the most votes is evicted from the house. The last nine evicted HouseGuests comprise the Jury and are sequestered in a separate location following their eviction and ultimately decide the winner of the season. The Jury is only allowed to see the competitions and ceremonies that include all of the remaining HouseGuests; they are not shown any interviews or other footage that might include strategy or details regarding nominations. The viewing public is able to award an additional prize of by choosing "America's Favorite HouseGuest". All evicted HouseGuests are eligible to win this award except for those who either voluntarily leave or are forcibly removed for rule violations.

Over the course of the game, several twists to the format were introduced.
On the first premiere night, Julie announced that the HouseGuests would vote for a Camp Director. That person would be safe from the first eviction as well, but they had to select four HouseGuests to "banish". Those four HouseGuests would then compete to stay in house. The three winners would go back into the house while the loser stayed banished and did not return. Michie was elected Camp Director and banished Cliff, David, Jessica, and Kemi. David lost the competition and was evicted.
On the second premiere night, Julie announced the Whacktivity Competition where a game-changing twist would be unleashed onto the house. Every week for the first three weeks, five designated HouseGuests, unless previously evicted (denoted with <s>strikethrough text</s>), would play in the competition to win a special power in the house.
During the first live eviction show, Julie announced to the audience that the first person voted out of the game would not go anywhere. After revealing Ovi's eviction, the HouseGuests were told that the evicted HouseGuest would not leave the house as normal, but live inside the house as part of Camp Comeback. At this time, David returned to the house. One of the first four HouseGuests to be eliminated would win their way back into the game. The evicted HouseGuests would not compete in competitions or ceremonies and would sleep in a special bedroom. The four HouseGuests, David, Ovi, Kemi, and Cliff, competed immediately after Cliff's eviction on Day 30. Cliff won and made his way back into the game, while David, Ovi, and Kemi were forced to immediately leave the house for good.
This twist also postponed Have-Nots as the Have-Not room was being used by the HouseGuests in Camp Comeback.
A twist called America's Field Trip was teased at the end of the July 25, 2019 eviction episode. On the August 1, 2019 eviction episode, it was revealed that America would vote for three HouseGuests who would compete against one another, with the winner being given immunity for the week, the runner-up being given a punishment and the loser being a third nominee. Should this third nominee be vetoed, no replacement nominee would be named, with only the HoH's two nominees facing the eviction vote. Voting for America's Field Trip opened shortly after the twist was revealed on the August 1, 2019. Voting closed on August 9, 2019, with the competition taking place shortly after. That same day, Analyse, Christie and Michie were voted in to compete in the competition. Michie won, meaning he was immune from eviction for that week. Analyse was the runner-up and received a punishment. Christie lost and was nominated as the third nominee.
During the eviction episode on August 23, it was revealed that Prank Week would take place during Week 9 in the House.
The main feature of the week was America's Prankster twist. The HouseGuest voted as "America's Prankster" anonymously nominated one HouseGuest for eviction at the Nomination Ceremony, leaving the Head of Household with only one nomination. If their nominee is taken off the block by the Power of Veto, they will also anonymously name the replacement during the Veto Meeting. Holly, as Head of Household, was not eligible to be voted for America's Prankster. Voting opened for America's Prankster on August 22, 2019 at 6:30 pm PT (9:30 pm ET) and closed on August 23, 2019 at 9:00 am PT (12:00 pm ET). Nick won and, on Day 66, nominated Christie.

This season was the least-watched and lowest-rated season of the series with about a 20% decrease in viewers and 25% decrease in demographics from the previous season. The season ended with an average viewership per episode of 4.38 million, over one million fewer than the previous lowest. Despite the decrease in ratings, CBS announced on September 5, 2019 that Big Brother was renewed for its twenty-second season and will premiere in the summer of 2020.
Big Brother 21 was criticized negatively by critics and fans due to the HouseGuests' discriminatory tendencies. Professor of African American studies and the UCLA Dean of Social Sciences, Darnell Hunt, stated, "Race is the central axis of social relationships. Even when, in public, we try to deny its significance, it creeps through in unexpected ways. When people are in a house like that 24 hours a day under those conditions, it's difficult to hide an inconvenient truth about American culture and society. The camera is the great equalizer." However, the way CBS handled the situations was somewhat praised by viewers as they dedicated a time during the live finale to address them and let the HouseGuests explain themselves. Justin Carriero of The Young Folks wrote, "These HouseGuests got away with a lot and they avoided the blowback by being in jury, so they had no idea what storm was heading their way. They needed to know what they did and how the public viewed them." He ended up rating the finale an eight on a scale from one to ten. Overall, the season was criticized for its non-diverse casting, leniency with specific rules like Have-Not rules, and deceptive editing of the episodes compared to the events shown on the 24/7 Live Feeds.
Following the two-night season premiere, HouseGuest Jackson Michie received the "Camp Director" power and was required to choose four HouseGuests to banish. Michie chose David Alexander and Kemi Fakunle, the season's only two black HouseGuests, Jessica Milagros, a Latina plus-size model and Cliff Hogg, the oldest person in the house. But, other viewers suggested that Michie only picked Fakunle due to lack of communication and that Alexander, Milagros and Hogg were only picked because they competed against him for the position of Camp Director. Once the Live Feeds began, Jack Matthews started making obscene and prejudiced remarks about fellow HouseGuests Kemi Fakunle, Ovi Kabir, and Jessica Milagros, behind their backs. Matthews was warned by production about comments made and to prevent further such comments. Many of his comments were addressed in episode 20 during his post-eviction interview with Julie Chen Moonves where he denied racism being behind any of the comments, though he did apologize for his actions that were deemed offensive.
During Week 3, an incident involving the dominant "Gr8ful" alliance, which was partially shown during episode 10, was sharply criticized by the viewing audience. The incident started when Nicole Anthony confided in Isabella Wang, telling her that the majority alliance, spearheaded by Jack Matthews and Jackson Michie, would come after Wang and Nick Maccarone, but Wang, who was included in this majority alliance with Maccarone, immediately told the group about it. The alliance swiftly denied Anthony's idea that they would target the couple despite earlier conversations where they discussed targeting them. The group proceeded to speak very negatively of Anthony. This incident was brought back up during the live finale to give the HouseGuests a chance to talk about the matter.
During Week 4, Cliff Hogg, the then Head of Household, named Jackson Michie as one of the Have-Nots for the week. Despite being named as a Have-Not, Michie was seen on the Live Feeds breaking the Have-Not rules by eating prohibited food behind the shower wall out of camera view. Michie received no punishment normally given to HouseGuests who break the Have-Not rules. After this incident, the Have-Nots aspect of the game was not included for the remainder of the season.
At the 2019 Television Critics Association, CBS executives were questioned about diversity and racism issues on Big Brother. In an open interview with CBS executives, Big Brother was accused of giving "contestants of color unfair cuts or early eliminations" as well as editing out comments by HouseGuests that have been interpreted as racist. CBS executives defended editors of the show stating that it's difficult to edit days worth of content into 40 minutes. CBS executives also stated that they would "closely reexamine Big Brother 21 and see if we can do better next year."
