STAGE TUBE: Jeff Probst Gives 'Behind-the-Scenes' Look at Tonight's SURVIVOR Challenge

On tonight's episode of CBS's SURVIVOR: ONE WORLD, contestants must face the "Spinning Wheel" challenge. In the clip below, executive producer and host Jeff Probst gives viewers a behind-the-scenes look and discusses how the object of the game is to get the contestants dizzy and then race to solve a puzzle. The episode airs tonight, Wednesday, May 9 at (8:00-9:00 PM, ET/PT) on CBS.

Eighteen castaways compete on SURVIVOR: ONE WORLD. 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, will have to decide whether to share their resources with each other or leave the opposing tribe to fend for themselves.

The 18 castaways are 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.
