The third round of the game was paint the wall where Sreesanth and Romil had to paint the wall Blue and Yellow respectively, the one who painted the maximum portion of the wall will win the game. The games were quite bold and edgy which brought out the true "Vyaktitva" of each contestant.  Sreesanth and Romil got into a physical brawl while painting the wall while Dipika and Somi in spite of being in the same team disagreed on some comments passed during the question and answer round.

Deepak manages to take away the bottle and goes on his stand to sit with it. But he is not ready to keep it on the stand, which is against the rules. Surbhi Rana, who is the sanchalak asks him to keep it, but he behaves rudely with her and she feels bad. She later gets angry and tells Deepak that he is not stable mentally.

There will be an apple tree set up with Appy Fizz bottles hanging on it in the activity area along with a gaming zone, in the garden area. Two boxes have been designated to each team. The task is divided by three challenges which will be conducted in the activity area and after winning each challenge the winning team has to pluck one Appy Fizz bottle from the tree and keep it on the box designated to their team. The opponent team can also steal the bottle but can’t hide it anywhere. The first challenge was a Question and Answer round where Surbhi asked quirky questions about the game to Dipika and Deepak who represented their team respectively.  There was a strong verbal argument amongst each other where Dipika declared Karanvir as the worst captain of the season.
