The contestants live in the same house with hundreds of hidden cameras. Audiences can watch them 24 hours live on TV and online. Each week, the contestants are assigned individual songs and sometimes group songs to perform on stage every Saturday until the last week of the show.

After each performance, the commentators will evaluate the performance. At the end of the concert, the contestant(s) who received the lowest percentage of audience votes will have to leave the show. The winners and the runners-up will automatically receive record deals with the True Fantasia record label. After the end of each season, there is a nationwide concert tour starring the top 12 finalists.
