The game, which came in two rounds, saw the housemates fight toe-to-toe to get the crown and be immune to possible eviction this week.
Yemi and Nelisa, housemates at the ongoing Big Brother Titans show have emerged as this week's Head of House after winning the HOH challenge.
Housemates were presented with five desks and chairs, each with a dictionary, a whiteboard, and a marker Nearby were three black buckets, each filled with different items, including more than 100 alphabets.
They were asked to first find a 12-letter word in the dictionary. It can be any word of their choosing. However, it had to be 12 letters.
For the second round, the remaining pairs, Kaniva and Yelisa, were given three minutes to place the names of the continents and oceans in the correct place on a map. Yemi aced this task, bringing his team to victory.
Unfortunately, Juvone, Khosicle, and Thabana were barred from taking part in the Challenge for breaking the rules of the Great Divide.
