The show follows a group of contestants (known as HouseGuests), who live in a house together while being constantly filmed and having no communication with the outside world as they compete to win a grand prize. Each week, the HouseGuests compete in a Head of Household (HoH) competition which gives them immunity from nominations and the power to save one of the nominees up for eviction.
On eviction night, the audience votes to evict one of the nominees.[2]
The season premiered on 2 December 2024.[3] It is the third continuous season to air on Telefe after making its return to the network in 2022.[4]
Format
The show 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.[5] 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 another HouseGuest to be saved for eviction. On eviction night, the audience vote to evict one of the nominees, and the nominee with the most votes is evicted from the house.[2]

Repechage
In Week 6, after Andrea walked from the game due to health reasons, it was announced that a repechage would take place among the first seven evictees during Week 7. As Keila was ejected from the game, she was ineligible to take part in the repechage.[9]
HouseGuests
A total of 24 HouseGuests moved into the house on Day 1 (2 December 2024), making it the season with the highest number of newcomers that join the house in the first episode.[10] Former evicted HouseGuest Brian Alberto returned to the house on Day 35 (5 January 2025),[11] and on Day 36 (6 Jaunary 2025) it was announced that new HouseGuest Katia Fenocchio would enter the house as a replacement.[12] Another evicted HouseGuest (Jenifer Lauría) returned to on Day 43 (13 January 2025).[13]
After winning the HoH competition on Day 2, Santiago banned Delfina, Jenifer, Petrona and Sandra from nominating this week. On Day 3, Carlos, Delfina, Luciana and Ulises were nominated.
On Day 4, Santiago decided to save Luciana from eviction, and nominated Claudio instead. On Day 8, Carlos and Claudio were saved by the public, and Delfina became the first evicted after facing Ulises.
On Day 10, Sofía won the HoH competition and decided to ban Giuliano and Ulises from nominating, and nominated Martina and Renato for eviction. In the Nomination Gala on Day 11, Luciana, Luz, Santiago and Ulises were also nominated.
Sofía decides to save Luz and put Keila up for eviction on Day 11. During the Eviction Gala on Day 14, Keila, Luciana, Martina and Ulises were saved by the audience with the fewest votes. Renato was faced against Santiago and was finally evicted with a percentage record of 92.3% of negative votes.[19]
On Day 15, Ulises won the HoH competition and was awarded to double his nomination votes, the right to give one HouseGuest immunity from the next eviction, and the right to nominate two HouseGuests' without the possibility of being saved. Renato chose to void Andrea’s votes, Brian was nominated as punishment for opening a kiosk box without permission and Ulises chose to give immunity to Giuliano and nominate Andrea and Santiago up for eviction. On Day 17, Chiara, Jenifer, Luciana, Luz and Sandra were also nominated by the HouseGuests.
On Day 18, Ulises decided to save Sandra and nominate Martina, but it was later nulled as he previously discussed his votes with other HouseGuests. On Day 21, Andrea, Brian, Luciana, Sandra, Santiago and Chiara were saved by the public, and Jenifer was finally evicted after being faced against Luz.
As Luca won the HoH competition on Day 22, he won immunity for the week's eviction. On Day 23, while competing for the weekly budget, all of the HouseGuests chose to abandon it, and were punished by Gran Hermano who decided to modify the eviction gala and eliminate two HouseGuests this week in a positive voting nomination in which all would be up for eviction. Andrea, Brian, Chiara, Lourdes, Luciana, Luz, Petrona, Sandra, Santiago and Ulises were the first HouseGuests to be saved with the most positive votes on Day 25.
The remaining HouseGuests that were not previously saved continued to be up for eviction, with Candela and Ezequiel being evicted on Day 28 after receiving the least amount of votes to be saved.
After winning the HoH competition on Day 29, Giuliano gave immunity to Chiara and nominated Lourdes and Sandra without the possibility of being saved, and Jenifer voided Sandra's votes. On Day 31, Andrea, Brian, Juan Pablo and Luca were nominated.
On Day 32, Gran Hermano decided to eject Keila from the house due to several complains about the production, the house and the format. On the same date, during the debate, Giuliano had to evict one HouseGuest, whom had to choose to either remain evicted or head into hiding and return to the house at the next eviction gala; Giuliano chose Brian to evict. Brian decided to enter hiding and return at the eviction gala on Day 35. Giuliano also saved Juan Pablo from eviction and nominated Petrona. Three days later, Luca was finally evicted by the public vote.
On Day 36, Juan Pablo won the HoH competition and was awarded to nominate two HouseGuests without the possibility of being saved, chose a HouseGuest to double their votes and chose another HouseGuest to only cast one vote during the nominations. Juan Pablo nominated Sandra and Brian, doubled Chiara's votes and allowed Lourdes to only cast one vote. On Day 38, Andrea decided walk from the game due to health reasons. Carlos, Claudio, Lourdes, Martina, Sandra, Santiago and Sofía's votes towards Chiara, Giuliano, Luciana, Petrona and Ulises were voided due to previously discussing nominations. Santiago answered the Red Phone and chose to Sofía and Chiara to face eviction. Giuliano, Lourdes, Luciana, Martina and Sebastián were also nominated.
On Day 39, Juan Pablo's choice of saving Sofía and nominate Santiago was nulled as a punishment for discussing his choices on the previous days. During the eviction gala on Day 42, Sebastián was finally evicted with the least votes as the public were voting to save rather than evict during this week.

HouseGuests can also use the Diary Room's Special Nomination, which gives three and two points instead.
