Season chronology | |
Big Brother 27 is the twenty-seventh season of the American reality television program Big Brother . The program is an adaptation of the franchise created in 1999 by John de Mol. The season features a murder mystery hotel theme. It premiered on CBS on July 10, 2025, with filming beginning two days prior and running for 83 days, concluding on September 28, 2025. [1] [2] The season also celebrates the 25-year anniversary of the series as a whole.
Big Brother follows a group of contestants, known as HouseGuests, who live inside a custom-built house outfitted with cameras and microphones that record them at all times. [3] The HouseGuests are sequestered with no contact with the outside world. [4] 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. [5] [6] Each week, the HouseGuests compete to win power and safety inside the house. At the start of each week, the HouseGuests compete in a Head of Household (HOH) competition. [7] The winner of the HOH competition is immune from eviction and selects two (or, in certain seasons, three) HouseGuests to be nominated for eviction. [8]
Six HouseGuests are then selected to compete in the Power of Veto (POV) competition: the reigning HOH, the nominees, and other players selected by random draw. The winner of the POV competition has the right to either revoke the nomination of one of the nominated HouseGuests or to leave them as-is. If the POV winner uses this power, the HOH must immediately nominate another HouseGuest, other than the POV winner, for eviction. [9]
On eviction night, all HouseGuests vote to evict one of the nominees, though the HOH and the nominees are not allowed to vote. This vote is conducted in the privacy of the Diary Room. The nominee with the most votes is evicted from the house. [10] In the event of a tie, the HOH casts the tie-breaking vote. The last seven evicted HouseGuests comprise the jury and are sequestered in a separate location following their eviction. 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. [11] When there are only two remaining HouseGuests, the jury will vote for the season's winner, who receives a grand prize of $750,000. The viewing public awards an additional prize by choosing "America's Favorite HouseGuest", with the award being worth $50,000. All evicted HouseGuests are eligible to win this award except for those who either voluntarily leave or are forcibly removed for rule violations. [12]
The initial cast of sixteen contestants was revealed on July 8, 2025. [13] An additional seventeenth contestant was teased prior to the beginning of the season. [14] During the premiere, this was revealed to be season 12 HouseGuest and season 13 winner Rachel Reilly. [15]

Sixteen new HouseGuests enter the house, but excitement turns to chaos when "The Mastermind" appears, kidnaps host Julie Chen Moonves, and steals the "HOH Relic". The HouseGuests are split into two groups of eight. One group—Adrian, Amy, Ava, Lauren, Mickey, Rylie, Vince, and Zach—must solve a massive bridge puzzle to access eight doors, each hiding a clue from Julie. Zach correctly chooses the door where Julie is held, winning $10,000. The other group—Ashley, Jimmy, Katherine, Keanu, Kelley, Morgan, Will, and Zae—searches through a room of fake relics to find the real one. Jimmy finds it and earns the power to choose four HouseGuests—himself, Adrian, Ashley, and Vince—to compete for Head of Household. In the HOH competition, they must balance six cores on their BB Blaster for 10 seconds. Vince succeeds and becomes the first HOH. After the HOH competition, the HouseGuests are surprised by the addition of former player Rachel Reilly to the cast. Then, the Mastermind reveals that one HouseGuest is secretly their Accomplice. If the others correctly identify the Accomplice, the Accomplice will be evicted immediately; if they guess wrong, the Accomplice officially enters the game. | ||||||||||||

After some discussion, the HouseGuests—except for the Accomplice—secretly vote on who they believe the Accomplice is. Rylie receives 11 votes, while the remaining 5 go to Zae. However, the Mastermind informs them that they are incorrect. A flashback and confessional reveals to the audience that Amy is the Accomplice. In the Diary Room, Zach learns that, until the jury begins, he can use his $10,000 prize to purchase one-time immunity if he is nominated for eviction following a veto meeting. As a late arrival to the game, Rachel is granted immunity from the first eviction, though she must live as a have-not. Three other HouseGuests earn immunity through a Chain of Safety: Rachel grants safety to Will, who then chooses Zach, who completes the chain by choosing Ava.

Following the nomination ceremony and the fallout from "Showergate," Ashley tearfully confronts Vince in the HoH room, feeling deeply hurt by his decision to nominate her. Meanwhile, Zae remains calm and ready to compete in the upcoming Veto competition. Rachel and Zach are selected to join Amy, Ashley, Vince, and Zae in the "Campsite Caper" Veto competition. For this competition, participants had to inspect three crime scenes by matching shoeprints, tire tracks, and scents, then correctly identify each perpetrator. Ashley won the Golden Power of Veto. Shortly after, a new alliance—the "Heavy Hitters," made up of Jimmy, Morgan, Rachel, Rylie, Vince, and Zach—is quietly formed. On Day 7, Ashley uses the Power of Veto to remove herself from the block, prompting Vince to nominate Kelley as her replacement.

Elsewhere in the house, Kelley begins to regret her decision to go up as a pawn. Rachel, meanwhile, starts campaigning for Zae to be evicted if he remains on the block after the upcoming BB Block Buster competition. When Zae hears about her plan, he publicly confronts her. Their heated and awkward exchange makes it clear to the entire house that they’re targeting one another.

Meanwhile, Rachel is thrilled to learn that Rylie, going against the Burger Boys, sided with the women to save Amy. Chaos strikes the house when the “Mastermind” breaks into "Hotel Mystère", stealing three powerful game advantages and the HoH key from the safe. In the "BB Break-In" competition, HouseGuests must navigate pitch-black sewers to recover the stolen items. Jimmy finds the missing HoH key, becoming the new Head of Household. Keanu earns the "Mystery Competitor" power, allowing a former HouseGuest to compete in the veto on his behalf. Kelley secures the "Mystery Veto," granting her a chance to compete in a private veto challenge after the standard one.

Sometime after the nomination ceremony, several HouseGuests express their hopes that either Keanu or Kelley will be evicted this week. At the Veto draw, Keanu activates his "Mystery Competitor" power, altering the standard competition rules. Only one HouseGuest is drawn to play: Ava. Keanu continues to irritate others with his communication style, further isolating himself. During the Veto Competition, former Big Brother 20 winner Kaycee Clark enters the house to compete on Keanu’s behalf. The "Caught Creeping" competition, requires players to hold two buttons on a wall until they hear the code word "Creeper" — announced by Big Brother 25's Felicia Cannon.

After making five nominations this week, Jimmy draws criticism from Mickey and Morgan for not collaborating with them—especially over his decision to nominate Will. Most HouseGuests view Jimmy’s nominations as safe gameplay. Meanwhile, Katherine and Lauren rally to evict Amy, feeling more secure aligning with the men in the house. Rachel, however, pushes for Adrian’s or Will's eviction, seeing them as a stronger threat. In the BB Block Buster competition, "Puzzling Prints," HouseGuests race to complete a 12-piece puzzle. Adrian secures the win and removes himself from the block. On Day 17, Amy is evicted from the Big Brother house by a unanimous 13–0 vote.

After the Veto ceremony, Keanu and Kelley feel burned yet again by Vince. Ava has been guaranteed safety from other HouseGuests if she were against either Katherine or Kelley. Meanwhile, Rachel and Keanu continue to flip-flop between frenemies and now full-blown enemies. Keanu also makes an effort to mend his relationship with Vince. Lauren and Ashley discuss the possibility of keeping Katherine over Ava, unaware that Ava is secretly in the room and overhears everything. Determined not to go down without a fight, Katherine rallies for votes to stay. In the "Hilltop Heist" Block Buster competition, nominees must guide a ball down a puzzle-like ramp in the fastest time. Kelley wins the competition, removing herself from the block and leaving Ava and Katherine as the final nominees. On Day 52, Katherine is evicted from the Big Brother house by a vote of 7–1, with Lauren casting the only vote to keep her. | ||||||||||||

Following Katherine’s eviction, Lauren is hurt by the loss of yet another ally. Several HouseGuests start to regret not evicting Kelley back in Week 3, when she sat on the block next to Jimmy. Keanu makes an effort to mend fences with Rachel, regretting having targeted her. Videos begin playing on the Memory Wall. In the "Mystère Moments" HoH competition, players are tested with a series of True or False questions based on the video clips. Keanu answers the final question correctly and becomes the new Head of Household. Keanu sets his sights on Morgan, believing she’s been whispering in Vince’s ear all season and driving his decision making. With the "Frenemies" back on, Keanu and Rachel attempt to align their goals for the week. Vince, sensing the danger, pleads with Keanu not to put him on the block next to Morgan, even promising not to use the Veto on her if he wins it. Keanu isn’t swayed and flatly tells Vince he’ll be nominated. Keanu searches for a third nominee and is stuck between Mickey or Ava. On Day 53, Keanu nominates Mickey, Morgan, and Vince for eviction. | ||||||||||||

On May 14, 2025, CBS announced that Big Brother 27 would premiere on July 10, 2025. [43] Promos for the season suggested an overall theme related to secrets and mysteries, with television commercials featuring whispered conversations, and a promotional image of host Julie Chen Moonves posing with a wall of skeleton keys described as being able to "[unlock] unexpected mysteries in the Big Brother house". [44] [45] [46] Filming began on July 8, 2025. [47]
The theme for Big Brother 27 was ultimately revealed to be "A Summer of Mystery", with the house being re-themed as the "Hotel Mystère". [48] The A.I. Arena twist from the previous season was revived as the "BB Block Buster"; as before, the HoH picks three nominees for eviction instead of two, with the three nominees then competing in a challenge for a chance to be saved from eviction. [49] [50]
The season premiered on CBS on July 10, 2025. [51] Thereafter, new episodes are set to air on Sundays, Wednesdays, and Thursdays at 8:00 p.m. eastern time (ET), with Wednesday night episodes lasting 90 minutes long. A new companion show—Big Brother: Unlocked—will air bi-weekly on Fridays beginning July 25; the show will feature additional footage and behind the scenes content, interviews, and guest analysis from alumni of past seasons. [43]
Following their broadcast, new episodes stream on Paramount+ and CBS On Demand. As with previous seasons, Paramount+ is also providing access to 24/7 live feeds. The live feeds also stream on Pluto TV in a free advertisement-supported format.
