Amber Siyavus (born 1980), 35, (formerly Tomcavage before her divorce) is a cocktail waitress at Caesars Palace casino in Las Vegas, Nevada.
She was shocked to learn that her former best friend Jessica would be playing the game as well.
On Day 1, the two enemies quickly made a deal with each other to keep one another safe, but both expressed their doubts about the other in the Diary Room.
Amber and Daniele later learned that they would be competing on the new CBS game show, Power of 10.
On Day 52, Amber and Daniele went head to head on the show, in which Amber beat Daniele in the opening round by a score of three to zero. She went on to play for $100,000 but missed the question.
