Double Up twists

• Double-Up Housemates - Two sets of identical twins were included in the roster of housemates - with each member of the twins living in both parts of the house, switching between the two areas when instructed. However, the rest of the housemates do not know about the twins, or the fact that there are two houses. The twins will also receive immunity from nomination for eviction during the first nomination night if they succeed in keeping this a secret, but if they do reveal it they will be forcibly evicted.
• House Swaps - Housemates are made to swap houses and group members as instructed by Big Brother.
• * Bagyong Walay - Big Brother instructed female housemates from Houses A and B to swap houses.
• * Bagyong Isa - Housemates from both houses will be staying in one house. Fourteen housemates should survive Vote To Evict in order for them to stay in one house.

  Other twists

• Vote To Evict - The public is given the power to vote to evict a housemate. The housemate with the highest percentage of votes to evict will be evicted at the end of the week. This was only implemented on the fifth eviction night.
• Save-Evict Voting System - The public saves a housemate, and at the same time, evict a housemate. The housemate with the combined percentage of both save and evict votes combined is evicted.
• Big Brother Swap - Carrying on from the second regular season, a Filipino housemate would temporarily trade places with a housemate from another active Big Brother season abroad.
• Head of Household and Hand Grenade - The Head of Household twist is once again used with the Hand Grenade as the new addition. Both were implemented after the housemates began living in one house. The Hand Grenade goes to the ultimate loser in the HOH competition. See Head of Household and Hand Grenade sections for further details.
• Char-Char Change - Big Brother made a fake announcement that public voting is discontinued and the housemates themselves will vote among the nominees for who should be evicted, but the ultimate fate will still be decided by the public. Big Brother used this system to show each housemate's true feelings toward their fellow housemates. The name of the twist is a play on Charter change and "Char-Char," which is Filipino slang for "false."
• House Players - Evicted or former housemate/s will return to the house to test the remaining official housemates through tasks set by Big Brother and the audience.
• The Big Jump to the Big Night - The seven remaining housemates will undergo a series of challenges. The overall winner will be granted permanent immunity from nominations and automatic inclusion into the Big Night.
• The White Room - Two of the six remaining housemates would undergo an endurance challenge in a purely white room for a chance to win a brand-new house and lot. A housemate would lose the challenge if he or she pressed a red button somewhere in the room.

  Finale twists

• Big Five - Big Brother decided to put five housemates in contention for the Big Winner title instead of the standard four; the "Fifth Big Placer" would get PHP100,000 as his prize and the same amount for his chosen charity.
• Big Reveal - For the first time in the franchise's history, the actual ranking of the finalists were revealed to the public before the Big Night. This happened on Day 129.
