Kamikaze (also known as Rock Block) is a recurring challenge from Survivor.
Castaways must race to smash a series of tiles using a metal ball or coconuts. The first person/team to finish wins.
The challenge debuted in Survivor: Palau. Each contestant had five color coded tiles in a grid of 35 tiles. Ian Rosenberger ended up winning the challenge due to Tom Westman accidentally breaking his last tile.
The challenge was used again in Survivor: Tocantins as the first Reward Challenge after the merge. The Forza tribe was divided into three teams. In a close race, the black team of Brendan Synnott, Debbie Beebe, and J.T. Thomas won.
The challenge reappeared as the first four-player Redemption Island duel in Survivor: Redemption Island. Mike Chiesl was the first to finish, followed by Matt Elrod, and Ralph Kiser, and Steve Wright was eliminated from the game for good. For coming in first, Mike was also given the choice of whether to see his loved one, to allow Matt and Ralph to see their loved ones, or to have the remaining castaways of the Murlonio tribe see their loved ones. He ultimately decided to give the most good to the most people, allowing the members of the Murlonio tribe to spend the afternoon with their loved ones at camp.
