The only information about the show I could find out from the official Colors Kannada Twitter and Facebook. I couldn't find any of the official housemate photos, so the pictures are from when they entered the house. The housemates that entered were:
Pratham, Vanishri, Bhuvan and Sanjana were nominated for eviction on 11th October. I'm trying to find the nominations.
Vanishri was evicted on 17th October. Om Prakash Rao, film director, also entered the house as a new housemate. The second picture below is him in the house with Pratham.
After Vanishri was evicted, Kirik became the Captain. I'm not sure how. Dodda, Kavya, Sanjana, Pratham and Sheethal were nominated for eviction on 18th October.
