The castaways must each race under a net crawl and make their way to a table where they must slide tiles into a target. Once all the tiles are through, they must use a machete to transport those tiles over a teeter-totter and balance beam to the finish table. They must then sort the tiles into pairs. Three of the tiles will not match up. Those three hold the code to a combination that will unlock their box. The first person to unlock their box and raise their flag wins.
In Millennials vs. Gen X, the contestants had to transport ten discs over a balance beam and then through a wire maze. After they had all ten discs at the finishing podium, they had to roll the ten discs through a slot. The first person to land all ten discs in their compartment wins.
In Edge of Extinction, it was more similar to its original Worlds Apart counterpart (sans the net crawl), though the letter tiles were now transported with two handles, and the challenge instead ended with a word puzzle in which the tiles must be used to spell out a phrase.
The challenge reappeared in Survivor: Kaôh Rōng as the final four Reward Challenge for food. After fixing her mistake on the tiles, Aubry Bracco won and shared the reward with Cydney Gillon.
Upon its return in Survivor: Edge of Extinction, Aurora McCreary expressed visible disappointment when being told that the final leg was now a word puzzle, stating she was no good at them. In a close race, Rick Devens pieced together the phrase "NOT LIVING ON THE EDGE TONIGHT" quicker than his competition, winning a well-timed individual immunity for himself, much to Aurora's chagrin.
