The duo of Chinne and Nne, known as NdiNne, emerged victorious in the inaugural Custodian Challenge of Big Brother Naija Season 9 on Sunday night.

This challenge marked the first task undertaken by the housemates.

With their win, NdiNne gains the power to influence this week’s eviction nominations. Additionally, they are immune from this week’s eviction.

The housemates will next compete in the Head of House and Immunity Challenge on Monday.

The winners of the Head of House and Immunity Challenge will also be exempt from this week’s eviction.

Big Brother previously introduced a new twist for this season's Head of House challenge. According to the new rule, the challenge will involve a ballot system.
