The first set of hopefuls audition in front of the judges in a closed room enviroment hoping to gain a place in the next phase of the competition where they will have to perform at Wembley Arena in front of a live audience. The auditions begin in Cardiff and first up is Luke Friend who manages to impress all the judges. In Mancheater, Alejandro Fernandez and Tom Mann manage to impress as well. J Star fails to impress though with his strange audition in London. Fil Henley fails to get throw after the judges aren't impressed by his rock star performance. Nicole manages to convince the judges to give him another chance though and this time he gets through. Some of the acts end up leaving Sharon in fits of laughter as they perform whilst others just fail to make the grade. After Silver Rock perform the judges decide the girls work better as solo artists and they decide to put through as indivduals. Siana Schofield, Rielle Carrington and Hannah Barrett all manage to impress. Euphoria Girls fail to impress Gary but the rest of the judges still decide to put them through. More acts fail to impress but Luke Britnell impresses all the judges with his performance as does Sam Bailey.
Each X Factor judge is in charge of a different section of singers on the show. The judges do not know what section of the competition they will be in charge of until the audition process has finished. Each judge then has to pick four acts to take forward to the live section of the show. Each week the two acts with the lowest amount of public votes have to sing again in a final showdown after which the judges decide who should be eliminated. Once there are only five acts left remaining it becomes left to the public to decide who should go.
