Vertigo

Vertigo is a recurring challenge on Survivor.

Rules
In, contestants would stand on the top of a perch over the water. Upon starting the challenge, they would toss a bucket into the ocean and collect water which would then be poured into a bamboo chute, causing a flag to rise. The first person to grab their flag would win.

In, the initial format remains similar but the flag is now replaced with a key. After retrieving the key, contestants would then jump off their perch and swim to shore where they would use the key to unlock a box of ladder rungs. The rest of the challenge then played out using the rules of Great Escape Run. The first person to raise their flag would win.

In, after retrieving the key, contestants would then jump off their perch and swim to shore where they would use the key to unlock a series of puzzle pieces. The first person to solve their puzzle would win.

History
The challenge debuted in, where Terry Deitz won immunity in a close race.

The challenge was later used in as the final four immunity challenge. Although Natalie Bolton maintained a lead early, Amanda Kimmel eventually caught up and beat Natalie in assembling the ladder, granting Amanda a spot in the final three.

In, all three men finished the perch portion quickly and had a large amount of time to solve the puzzle. Kass McQuillen, on the other hand, took over 15 minutes to fill her chute. After one of the biggest comebacks in Survivor history, Kass beat the men to win immunity.
