Nelson Allison, one of the housemates in the ongoing Big Brother Naija (BBNaija) on Monday became the new head of house for the week after a seven minutes challenge.

This week’s head of house challenge was fascinating and intense, unlike the previous week where the head of house was elected.

The Big Brother’s challenge witnessed all 19 housemates trying to get pebbles from an oil-stained bucket of water with a peg.

Four housemates who had the highest amount of pebbles removed from the bucket unto the plate qualified for the next level.

At the end of the first stage, Kim Oprah had four peebles, Mike had five, Jackye – two, Jeff – one, Tacha – six, Diane – three, Omashola-six, Khafi- eight, Gedoni – one and Mercy -10.

Others housemates had:  Ike -eight, Seyi – seven, Thelma-five, Nelson – eight, Frodd -six, Sir Dee – two, Ella – two and Esther – three.

However, Tuoyo was disqualified from the game for touching the pebbles.

Mercy, Ike, Khafi and Nelson moved to the next stage which involved the housemates forming a tower with cookies and the game began at the sound of the buzzer which ended in two minutes.

The twist to this stage was that all cookies were to remain standing after 30 seconds.

At the end of the game, Mercy, Ike and Nelson all had 11 cookies each standing firm in the towers while Khafi had eight cookies on the tower.
