The format of the program remained largely unchanged from previous seasons; a group of contestants, referred to as houseguests, are enclosed in the Big Brother House under the surveillance of cameras and microphones. Each week the houseguests voted to evict one of their own until two houseguests remained on finale night. The winner was decided by the last six evicted houseguests, known as the Jury. The program included 13 participants, one of whom was expelled by the producers for constant rule breaking while the fate of the others were decided by their peers. Due to an increase in ratings over the previous season the season finale was extended from one hour to two hours with the final two being determined on finale night.
