Each Challenge pits numerous cast members from past seasons of reality shows against each other, dividing them into two separate teams according to different criteria, such as gender, which show they first appeared on, whether or not they're veterans or rookies on the show, etc. The two teams compete in numerous missions in order to win prizes and advance in the overall game.
Players from all walks of life will compete to win up to £50,000. All living in one modern block but separately in individual apartments, the players will never come face-to.face, and can only interact with one another through an specially-designed app called The Circle.
This game show sees contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel.
