Real World/Road Rules Challenge is a reality television series on MTV, that spun off from that network's two flagship reality shows, The Real World and Road Rules. The Challenge puts cast members from past seasons of the two shows against each other, usually dividing them into two separate teams according to different criteria, such as by gender, which of the two shows they first appeared on, etc. The two teams must complete challenges in order to win prizes and advance in the game. Recent seasons have taken a cue from other reality shows by adopting the system of eliminating contestants based on performance, or having a team vote a member into an elimination round, in which they must compete against a member from the other team to determine which one goes home.
