Big Brother Naija season 5

Big Brother Naija Season 5 also known as Big Brother Naija: Lockdown was the fifth season of the Nigerian version of the reality show Big Brother. It premiered on 19 July 2020 on Africa Magic and the live feed on DStv channel 198 and GOtv channel 29. Ex-housemate Ebuka Obi-Uchendu from season one returned as host.

The winner of this season is Laycon and he won ₦85 million worth of prizes.

Auditions
Due to the COVID-19 pandemic, a virtual audition was held to select contestants for the show. Video submissions were received from 20 May to 30 May 2020. During the submission, interested contestants submitted a two-minute video stating why they should appear on the show. At the end of the online audition, over 30,000 contestants showed their interest. Of the 30,000 contestants that showed interest, 20 Housemates were selected.

Nomination and eviction voting format
In the previous season of Big Brother Naija, housemates nominated two of their fellow housemates for eviction and the public then voted for the housemates they wanted to save. In that format, the housemate received the fewest votes would be evicted. In this season, the nomination and eviction format was reversed for the first half only.

Each week, all housemates, except the Head of House and Deputy Head of House, face the public vote. Public voting is opened every Monday night after the Head of House Game and closes on that week's Thursday night. The four housemates who receive the fewest votes will be nominated for eviction by the housemates.

During the live eviction shows every Sunday, the nominated housemates at risk face a Diary Eviction Votes Session to determine who among them will be evicted. In the Diary Room, each housemate votes on one or two of the bottom four housemates who they want to leave. The housemate who receives the most votes is then evicted.

During the sixth live eviction show on Day 42, the host Ebuka announced that the voting system would be switching back to the old one, with housemates nominating who they want to evict and the public voting who among these housemates to evict.
