Wrist Assured (also known as Water Weight) is a recurring endurance challenge of Survivor.


Castaways hold on to a handle with a rope wrapped around it. At the end of the rope is a bucket that contains a percentage of the contestant's body weight before the game began. As the challenge goes on, the rope will begin to unwind, making it harder to keep the bucket in the air. The last castaway remaining in the challenge wins.


The challenge first appeared in Survivor: Philippines as the first Immunity Challenge after the merge, where the last man and the last woman standing would win. Carter Williams outlasted Jeff Kent to win immunity for the men and Denise Stapley outlasted Abi-Maria Gomes to win immunity for the women.

In Survivor: Blood vs. Water, the players were given a choice whether to eat or compete. Ciera Eastin, Gervase Peterson, and Tyson Apostol opted to eat, while the other four chose to partake in the challenge. In a tight struggle to win, Monica Culpepper ended up beating Hayden Moss, winning her third Immunity Challenge since the merge.

The challenge was again reused in Survivor: Worlds Apart, when the last man and the last woman standing would be given immunity. After a close battle between Carolyn Rivera and Shirin Oskooi for the women and Mike Holloway and Rodney Lavoie Jr. for the men, Carolyn and Mike won immunity and were safe at the next Tribal Council.
