STAGE TUBE: Sneak Peek - Contestants Face The 7-Up Challenge on Tonight's SURVIVOR: ONE WORLD

On tonight's episode of CBS's SURVIVOR: ONE WORLD contestants must face the 7-Up Challenge. Four players will begin the "7UP" challenge by sliding down a steep water slide before racing out to the water to grab a key that will unlock multiple crates. After carrying the crates up to the beach, players must then give the keys to another tribe member who must then unlock the crates. Once all the crates are unlocked players will work together to solve a puzzle to win reward. The episode airs tonight from 8:00-9:00 PM, ET/PT on the CBS network. 

Eighteen castaways compete on SURVIVOR: ONE WORLD when the Emmy Award-winning series returned. The castaways must fight the elements, adapt to their new surroundings and vie against each other to stay in the game or be voted out by their peers, all while living together on the same beach. Tribes, separated by men versus women, have to decide whether to share their resources with each other or leave the opposing tribe to fend for themselves.

The 18 castaways were divided into two Tribes of nine: the Salani Tribe and the Manono Tribe, named after islands in Samoa. The tribes are comprised of individuals from all different backgrounds with the same ultimate goal: to outwit, outplay and outlast and ultimately be crowned Sole Survivor. The show is hosted by Emmy Award winner Jeff Probst.
