"I didn't know the game would be so dirty. I don't think the people there can play a clean game. And if they had, I would have stayed till the end and won, " Debojit told over phone from Mumbai.
The reality show required Debojit to be locked in a specially designed house with celebrity inmates for three months under 24-hour camera surveillance, completely cut off from the outside world.
A past winner of music reality show "Sa Re Ga Ma Pa", Debojit says that if honesty prevails in the "Bigg Boss" house, model-actor Zulfi Syed or former Miss World Diana Hayden have a good chance to win.
Otherwise, Rahul Mahajan, son of the late Bharatiya Janata Party leader and former union minister Pramod Mahajan, has a definite chance to win, he said.
"Rahul is very far-sighted. His mind is very sharp and whatever he does, he does with a hidden intention. In the beginning, he started building good relations with each and everyone.
And now, he has become a big source of entertainment on the show. The public likes his bubbly nature. The way he jumps around everywhere and the way he flirts with the girls.
"So if the winner is to be chosen on the basis of who makes the show more entertaining, Rahul should win. If it is decided on who is the most honest and neutral, Zulfi or Diana might win, " said Debojit.
Other than these house members, Debojit feels Raja Chaudhary and Ashutosh Kaushik are the most clever and cunning.
"I used to get negative vibes from Ashutosh and Raja. They used to keep backbiting about others. I think Ashutosh was brought on this show only because he could have made the show more 'masaledaar' (spicy). He is a very sharp person but despite staying among celebrities, he did not change the way he is. He never used to stay clean.
"And Raja has extreme mental situations. If he was sweet, he would be extra sweet and the same goes for his arrogance. They (Ashutosh and Raja) both used to backstab, " Debojit said.
Debojit says he is happy that he is out of the game as it would get even more dirty now.
While on the show, he deeply missed his music, wife and parents and made a special mention of having missed the festivals of Durga Puja and Navratri that were celebrated with fervour last month.
"I am blank right now as far as music is concerned. I am forgetting songs and lyrics because I haven't heard any (song) for a long time, " he said.
With Diwali round the corner, Debojit is looking forward to joining his wife in Assam and completing some pending work before he sets back to his music career in full throttle.
