Contestants Format The Challenge UK consists of a main challenge, a winners' selection and an elimination round. Daily Challenge: Players compete in the main challenge in male/female teams of two. The last-place team is automatically sent to the elimination round. The winners earn the power to select a second team to compete in the elimination against the last-place team. Eliminations ("The Arena"): The last-place team from the daily challenge compete in an elimination round against the team selected by the winners of the daily challenge. The winners remain in the game while the losers are eliminated. Twists The Algorithm: Introduced after the first elimination, an algorithm assigns players a new partner of the opposite gender for the next game cycle. Players must be assigned a new partner they haven't been paired with, or cannot have the same partner twice in a row if they have already partnered with each eligible remaining player. Gameplay Challenge games Meet Me Halfway: Each team member faces off on a beam against a same-gender opponent from another team and attempts to push their opponent into the water below as fast as possible.
