Big Brother Naija Season 9 kicked off with an exciting debut challenge, where Chinne and Nne, collectively known as NdiNne, emerged as the winners on Sunday night.

This victory grants them immunity from eviction for the week and significant influence over the nomination process.

Additionally, they will be exempt from facing eviction this week.

The housemates will next compete in the Head of House and Immunity Challenge on Monday, with the winners also securing immunity from eviction.

In a surprise twist, Big Brother introduced a new voting system for the Head of House challenge, where contestants will participate in a ballot to determine the winner, adding a new layer of excitement to the competition.
