Twist of the season
The main twist of this season was 'chain reaction' which saw the house make one of the nominations as a whole.
 * Chain Reaction - Once the Head of Household was crowned, they would make one nominee and then 'save' one houseguest from possible eviction, that houseguest would then save another and so on and so forth until one houseguest remained, That houseguest would be nominated beside the HoH's nomination. On day 2 it was announced that if the veto is used on the chain nominee, the chain will start over, but from the original chain nominee, putting the power in their hands. On Day 15 it was announced that The Chain Reaction twist was over and that the houseguests would carry on a normal Big Brother game.
 * Double Eviction - This season saw two double evictions. There were double evictions on week six and week seven. It saw two houseguests leave in one night. Mike and Brian left in week six and Oakley and Isaac left in week seven.

Houseguests
Unlike past seasons, houseguests weren't announced by an official release of the names, instead, the houseguests were given the key to the Platinum Big Brother house 24 hours before, giving them 24 hours to pack and head to the house. This prevented pre-season alliances as the cast found out who was playing at the premiere, as did the viewers. The houseguests entered the house on January 5th 2014.

Voting History
The nominated houseguest in bold-face was selected as a nominee by the chain reaction twist. Penalty votes stay with the bearer until the final 5, houseguests could also receive penalty votes in competitions.
