"Big Brother 1" was similar to that of the one featured in the US version. A group of people, known as "HouseGuests", compete to win the show. They vote each other off to be the last HouseGuest remaining. One HouseGuest, known as the Head of Household, must nominate two of their fellow HouseGuests for eviction. The winner of the Power of Veto has the ability to change the nominations. If they choose to do so, the HoH must nominate another HouseGuest. The HouseGuests then vote to evict one of the nominees. The HouseGuest with the most votes is removed from the show. There was a twist for this season. A phone was placed in the house, and the first person to answer would receive a secret task.
