Big Brother 3 (U.S.)

Big Brother 3 is the upcoming third edition of Seth's Big Brother, set to premiere on February 15, 2013. The first round of auditions for the series began on February 10, 2013, before Big Brother 2 had concluded. The final cast is set to be revealed on February 14. The series will be the first to take place along with the Big Brother: The Big Mash-Up spin-off series, which will launch immediately following the season premiere. Seth has confirmed that 12 HouseGuests will participate in this season. Like the previous season, Big Brother 3 is set to last for a total of 30 days, with the winner being crowned on the final day. Big Brother 1 HouseGuest Ashley designed the logo for this season, as he did with the previous installment. This season will feature a new co-host, which will be a former HouseGuest.

The format for Big Brother 3 will remain largely unchanged from previous seasons, in which a group of HouseGuests compete to win the series by voting each other off and being 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, and if they choose to do so then the HoH must nominate another HouseGuest. The HouseGuests then vote to evict one of the nominees, and the HouseGuest with the most votes is evicted. The main mechanics of the game will not be affected by this season's twist, though it could influence how the HouseGuests play the game.

Production
The series was officially confirmed in January of 2013, after Big Brother 2 proved to be an early success. Seth also confirmed that the spin-off series, Big Brother: The Big Mash-Up would begin airing alongside Big Brother 3, and would feature former HouseGuests discussing the events of the game. Big Brother 3 has been described as a "send off" for the main series, with Seth confirming that Big Brother 4 will not begin until Summer of 2013. He stated, however, that a spin-off series is in the works. The first round of auditions for the season began on February 10, 2013. Big Brother 3 is slated to begin on February 15, 2013. Much like the previous season, the casting process will feature three rounds with numerous in depth questions about a HouseGuests time spent on Tengaged as well as their gameplay techniques.

Big Brother 3 will be the first season to feature a co-host appearing alongside Seth. This news was first announced on February 9, when Seth revealed that he would like to cast a former HouseGuest to be the co-host. He later stated that the co-host would appear solely for Big Brother 3, and would not be a permanent fixture for the series. He also stated that the series would continue to be known as Seth's Big Brother, and would not feature the name of the new host. The new host will be revealed during the Big Brother 2 finale.

Format
Tengaged contestants who apply for the series will be notified of whether they made the series or not. Each week, the HouseGuests took part in several compulsory challenges that determined who would win power in the House. The winner of the Head of Household competition was immune from nominations and was instructed to nominate two fellow HouseGuests for eviction. After a HouseGuest became Head of Household he or she was ineligible to take part in the next Head of Household competition. The winner of the Power of Veto competition won the right to save one of the nominated HouseGuests from eviction. If the Veto winner exercised the power, the Head of Household then had to nominate another HouseGuest for eviction. On eviction night all HouseGuests except for the Head of Household and the two nominees voted to evict one of the two nominees. Before the voting began the nominees had the chance to say a final message to their fellow HouseGuests. In the event of a tie, the Head of Household would break the tie and reveal their vote in front of the other HouseGuests. The nominee with the most votes from the other HouseGuests was evicted from the House. HouseGuests could voluntarily leave the House at any time and those who broke the rules were expelled by Big Brother. The last seven evictees of the season form the Jury that voted for the winner on the season finale, they were known as the jury members. None of the HouseGuests are aware of how the voting process went until after the season.

Those playing the game had to abide by numerous rules to continue in the game. All competing HouseGuests were required to vote for eviction, and could be punished if they failed to do so. They were also required to post in the forums every two days, otherwise expulsion could be used as a punishment. HouseGuests were required to participate in non-live competitions, though appearing at live competitions was not required. Another rule to the game was that HouseGuests would compete in the Have-Not competition, with the losing team receiving penalties in the HoH and PoV competitions. If a HouseGuest were to be banned from Tengaged, even for the shortest amount of time, they would be expelled from the game. Showing up to evictions was not a rule, but was greatly encouraged. The twist for this season has not yet been revealed!

HouseGuests
This season will feature 12 HouseGuests, which will be revealed the day before the premiere.
