Gran Hermano (Argentine TV series) season 13

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.^[4] 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.^[3]

Throughout the season, some of the voting will combined the elements of both the Vote to Evict and Vote to Save formats. After everyone has voted, HouseGuests with the most points were nominated for eviction. The public then have 24 hours to vote to save one of the nominees when the vote closes, the HouseGuests with the most votes were saved. The public decision then switched to vote to evict, where at the end of the week, the HouseGuest that receives the most votes would be evicted.

In Week 2, a new nomination system was introduced to target passive, low-profile HouseGuests who do not contribute to the house dynamics.^[2]

From Weeks 2-9, evicted Houseguests are given the power to give one HouseGuest three votes to use during nominations. The person who received this power will nominate with three, two and one points instead of the usual two and one points.^[2]

Just like last season, the HouseGuest that wins the HoH competition, gets series of Super Powers to use during the week.

Starting in Week 5, Gran Hermano enabled the Golden Phone. Similar to the Red Phone in seasons 11 and 12, whoever answered the Golden Phone would receive positive or negative information. The HouseGuests must answer the phone without being able to repeat it during the day and if the phone is not answered before five rings the whole house would be punished.

On 8 April 2026, a housemate exchange with La casa de los famosos USA was announced.^[5][6] Solange Abraham is set to be swapped with Fabio Agostini from La Casa de los Famosos season 6.^[7]

From week 10 onwards, the last evicted HouseGuest has the power to void any of the remaining HouseGuests' votes before they nominate in the Nominations Gala.

During week 10, Solange was ejected from the house. As a result of this, the Golden Ticket was enabled. Gran Hermano randomly chose one evicted HouseGuest to return to the House in Solange’s place. He chose Cinzia to re-enter the house.

During week 10, the repechage was announced. The repechage begins May 17th with the results being announced on May 20th.

A total of 18 HouseGuests moved into the house on Day 1 (23 February 2026).^[8] An additional 10 new HouseGuests moved into the house on Day 2 (24 February 2026).^[9] After Daniela de Lucía and Divina Gloria had to leave the house on Day 3, on Day 7 (1 March 2026) Daniela re-entered the house and Carla Bigliani entered to replace Divina.^[10] Due to the ejection of Carmiña on Day 17 (11 March 2026), another new HouseGuest (Jessica Maciel) entered the house on Day 21 (15 March 2026) to replace the former.^[11] On Day 29, Andrea del Boca returned to the game after leaving five days prior in order to seek medical attention.

Four of the HouseGuests previously participated in other editions of the show: Eduardo Carrera was a HouseGuest during season 3, Emanuel Di Gioia and Solange Abraham during season 6, and Jennifer Torres finished in third place on season 1 of Gran Hermano Chile.^[8]

HouseGuests nominate for two and one points, shown in descending order in the nomination box. The six or more HouseGuests with the most nomination points face the public vote.

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

From Weeks 2-9, the last evicted HouseGuest is given the power to give another one three votes to use during nominations. The person who received this power will nominate with three, two and one points instead of the usual two and one points.

Starting in Week 9, The Power Nomination (fulminante in Spanish) was enabled by Gran Hermano, which consists of the automatic nomination of a HouseGuest, without the ability to be saved by the Head of Household. It could only be used once by each HouseGuest throughout those weeks. HouseGuests that use the Power Nomination are marked in bold.

Starting in Week 10, the last evicted HouseGuest has the power to void any of the remaining HouseGuests' votes before they nominate in the Nominations Gala.
