Sequence Explosion is a recurring Power of Veto competition. It is an elimination-style veto based largely on memory skills.


  1. The houseguests will be given a large object and a number of smaller, differently-colored but otherwise identical items relating to the main object (for example: a bomb and its wires, a flask and several chemicals, etc.)
  2. To stay in this competition, the houseguests must either cut the correct wire or pour in the correct ingredient each round.
  3. A sequence of these items will play on a monitor in front of the houseguests. They will then be instructed to cut a specific wire or pour in a specific ingredient (i.e. "Cut the third wire that appeared in the sequence", "Pour in the chemical that appeared the most in this sequence")
  4. The houseguest must then display which item they will be cutting/using, and then use it.
  5. If the houseguest chose the correct item, they will advance to the next round. If they chose the wrong item, the large object will explode on them and they will be eliminated.
  6. The last houseguest standing wins the Power of Veto.
