The CBS reality titans take on their next challenge, "Yeah Buoy," where they must gather letter pieces from a rotating buoy high in the sky and form as many words as possible. Meanwhile, a SURVIVOR legend looks to cement their dominance in the game, a crafty BIG BROTHER player is a little too popular with other Challengers, and two LOVE ISLAND exes must put their differences aside in order to win a challenge.

Players take on one of hosts TJ Lavin's favorite challenges, trivia, while hanging over the ledge of a 30-story building.
