The head of house challenge was split into two parts with the first part carried out on Sunday after the launch and the second part carried out on Monday.
After the fake eviction of the six housemates who could not get bed spaces, Biggie announced the first task which involved padlocks.

The ‘ninjas’ entered the house with locks and keys and each housemate was told to pick a key.
The two housemates who could open the locks won Sunday’s task to qualify for the next round of the head of house tasks.
Ifu-Ennada, who opened the first padlock and Cee-C, who got the second one, were asked to keep the keys and the padlocks for the next round of the task.
On Monday, Big Brother brought together the winners of the first game with the lucky six who had been part of the ‘fake eviction’.
The coordination skills of the housemates were put to test in the second task, with the mission of building a balloon tower in just 15 minutes, which appeared to be fairly simple.
Tobi emerged as the winner, having built the tallest balloon tower of all.
Biggie granted him the privilege of picking his title and Tobi chose to be addressed as ‘Kabiyesi’ (which means ‘ruler’ in the Yoruba language).
As part of the perks of the title, Biggie also invited Kayibesi Tobi to choose a housemate to share the lottery bedroom with. Cee-C volunteered to share in Tobi’s luxury.
Housemates are competing for prizes worth N45 million on this season’s BBNaija which is tagged ‘Double Wahala’.
