Clarke won her first immunity challenge on Day 27 of the game. After that night's tribal council vote, another immunity challenge immediately took place, which she also won. At the game's final immunity challenge, Ozzy Lusth had a significant lead in the beginning, but after he got stuck on the puzzle, Clarke came from behind to win, and Lusth was subsequently voted out and became the last jury member.
