Niagara Balls is a recurring Power of Veto competition.


Houseguests start on a platform down below. Five thousand balls are dropped onto the houseguests, ranging in a multitude of colors. Houseguests must collect green balls and place them into their container.

The houseguest that gets eight green balls into their container the quickest will win the PoV.


The competition first appeared on Big Brother 4, during Week 3. Houseguest Nathan Marlow won the competition, winning his first PoV of the summer.

In its latest appearance, Big Brother 8, houseguests competed during Week 9. Houseguest Zach Swerdzewski won the competition, winning his first PoV of the season.
