The season finale featured challenges such as kayaking outside Giants stadium in San Francisco, climbing up the side of a giant building, baking two trays of fortune cookies inside a factory and finding and putting together 12 parts of an airplane that were scattered across aircraft carrier the USS Hornet.
Graf was able to assemble the plane parts first giving herself and Nickson the victory. Team Yale came in second with Team Extreme in third.
"He promised to make the half a million dollars we lost on #BigBrother. He doubled his promise," Graf said on Instagram in reference to the $1 million cash prize alongside a photo of herself kissing Nickson while being held in his arms.
