Ten housemates enter on launch night. Public begin to vote for their favourite. At the first eviction the housemate with the lowest number of votes is evicted, bringing the number down to 9.

The 9 housemates are then joined by 9 ex-HM from the previous nine series of Big Brother. The 18 housemates are split into two teams, the new housemates are knows as "Fans" and the returning ex-HM are known as "Favorites".

For the next 3-4 weeks the teams battle it out head-to-head to decide which team will be safe and which team will be nominated for eviction. After 4 weeks the teams merge and show carries on as normal.
