A "hidden immunity idol" is a special item in the reality TV show Survivor. Contestants can find these idols hidden around the game area, and they provide a significant advantage. When a player possesses an idol, they can use it to negate votes against them during a tribal council, ensuring their safety from elimination. Finding a hidden immunity idol often requires contestants to search carefully and solve clues. The presence of these idols adds an element of strategy, as players must decide when to reveal their possession of the idol or keep it secret to protect themselves from being voted out.
