Now Kaun Banega Crorepati prize money has gone up to 7 Crores in its 7th season. I personally haven't ever seen a full episode of the show so far. But i have sent in sms once or twice because of pressure from family members. Never went past that round though.
The big reason for me not watching the show is, it takes so long for the quiz show to start.
I prefer my quiz shows like the mastermind one. Where its all about quiz, not people praising the host, story about the participants life etc. Search youtube for bbc mastermind to see the show i am talking about.
