Similar to Whose Line Is It Anyway? and Drew Carey's Green Screen Show, the show features the performers acting in improvisational comedy sketches in front of a live audience using audience suggestions and audience participation. Many of the U.S. Whose Line alumni return for this show. Each episode consists of three or four improv games, each one introduced by a different cast member, with each game taking up an entire segment. Unlike Whose Line, the show is filmed at the MGM Grand in Las Vegas, Nevada. Instead of Drew Carey hosting and awarding "points", Drew is now a performer and takes part in games, and other performers take turns in "hosting" a game.
