when do judges houses start on x factor
The show is split into different stages, following the contestants from auditions through to the final. In the original televised audition stage of the show, contestants sang in an audition room in front of just the judges, but from the sixth series onwards auditionees sing on a stage in front of the judges and a live audience. In series 10 and 11, both auditions formats were used. In series 12, the room auditions were scrapped, leaving just the arena auditions. The room auditions were revived in series 13, and no arena auditions followed. Successful auditionees go through to "bootcamp" and then to "judges' houses", where judges narrow down the acts in their category down to three or four acts to mentor for the live shows, where the public vote for their favourite acts following weekly live performances by the contestants.
