The Housemates do not know about its existence and will know only when they are evicted. One of them will get the opportunity to come back in the (main) game as if they had never been evicted.
 * Krystal tied her destiny in the game to Jonathan, it means that whenever Jonathan is immune or nominated, Krystal will be too. The only time it does not work is when it comes to evictions.
 * Eva is permanently nominated because of her secret.
 * Glass House - Week 1: Returning players from previous seasons were back, Cindy from Secret Haus 1, Chris from Secret Haus 4, Shayna from Secret Haus 5 and Geoffrey from Secret Haus 7. Throughout the week, they would have a few challenges in order to win the most points. The two with the most points at the end of the week will become official Housemates, the other two will leave.
 * Week 1: Clément and Victoria were directly nominated. Both have a secret in common in which Clément is the guilty and Victoria the victim. It is up to the viewers to decide who must remain. Throughout the week, several clues about their secrets would be revealed in order for the other Housemates to discover it.
 * Week 2: Shayna and Geoffrey won the most points and therefore were officially Housemates while Chris and Cindy had to leave. As she made her entry one week late, Shayna was immune. Eva was automatically nominated as she was permanently nominated.
 * Week 4: As his secret was discovered, Sanjay was directly nominated and it was announced he would be nominated permanently weeks after weeks due to being the host's brother.
 * Week 6: Jonathan accepted to immune Alessandra in order to protect three clues on their secret, but therefore he also had to give an immunity to his nemesis : Geoffrey who would enjoy this in week 7.
