Co Head of Household

Platinum Big Brother, sometimes features a 'Co-Head of Household' which sees two houseguests share the head of household power, having to agree on the nominations or risk becoming the nominees themselves. This particular twist has featured twice during the series.

Platinum Big Brother 1
On the launch night of Platinum Big Brother 1, it was announced that the first HoH would actually be a 'Co-HoH' the winner of the first competition and the winner of the pass to the house (as part of the 'Tengaged Influence') would each have to nominate one houseguest each right away. Chris, the winner of the competition and Joe E. the winner of the poll became the first co-HoH. They nominated Tony and Victor B. for the first eviction.

Platinum Big Brother 3
After the second eviction of Platinum Big Brother 3, it was revealed that the house would see a 'clique collaboration' which was a spin on the Co-HoH twist, the two winners of the competition would not only have to nominate together, but they would be able to keep both their cliques safe. Joe E. and Joe J. became the second Co-Head of Household of the season. Keeping the Brains and Popular clique safe, they nominated Kiko and Nick P. after the veto was used, they named JoJo as the replacement nominee and at the eviction they voted to evict Kiko during the tie-breaker.
