Big Brother (Israeli TV series) season 12

HaAh HaGadol 12 (האח הגדול 12; lit. The Big Brother 12) is the Israeli version of the reality television show Big Brother. The twelfth season premiered on June 7, 2022, on Israeli broadcast channel Reshet 13.

The season was unique in several ways: for the first time in the program's history, the Big Brother house had several floors and an elevator. Two days before the start of the season, one of the housemates tested positive for COVID-19 and did not enter the house until the ninth day. On the third day, a person chosen at random was picked to join the Big Brother house, another first in the Big Brother franchise. On the fifth day, houseguest Talia Ovadia, ex-wife of contestant Eliav Tati, joined the Big Brother house.

Housemates
24 housemates entered the house on day one, and further participants entered on days three, five, and nine due to testing positive for COVID-19.
