"Four players have keys on lanyards and are locked into cages on pontoons. A fifth swims out to the nearest cage and unlocks it with their own key, releasing the prisoner, who crosses a set of small platforms to the second, and so on. Once all four prisoners are released, the final prisoner and their rescuer get into a waiting boat with the sixth player, who has a bunch of keys, then the three row to shore picking everyone else up on the way. These six form a human pyramid on the beach, and the person on top uses the key ring to unlock a hanging cage containing the seventh and final tribe member." ~ @SurvivorWiki
