Nomination Competition also called as Immunity Challenge is a special kind of Immunity Competition and at the same time a twist to the usual Nominations process.

Winning this type of challenge will secure the winning housemates a safety from facing the public for eviction while those who lose the challenge will be automatically nominated for eviction.

The challenge first appeared in Pinoy Big Brother and later appeared in Big Brother Brazil, Big Brother UK and Big Brother Nigeria.\


Instead of the usual nomination voting process, the housemates will compete in a series of immunity challenges to save themselves from being one of the nominees.

In some cases, the housemates may compete individually or they may be grouped into teams by Big Brother.

Elimination Format

For this format, the players will compete in a series of rounds, often in three to four challenges. In each round of the challenge, there will be a winner. Whoever wins in each round will be saved from the nominations and will be eliminated from the challenge, thus being ineligible to compete in future rounds. The housemates who remained and failed to win any rounds will become the week's official set of nominees for eviction

Scoring Format

Sometimes, the point system is used for the competition. The players will compete in a series of challenges and would gain a point corresponding to their place in the challenge; the first place gaining the largest points while the last place gaining the least points. After they all finished the competition, The housemates who gathered the least total points at the end of the competition will become part of the official set of nominees for next week's eviction.
