The contestant is going to be confined in a box while he answers the questions thrown at him.They will have all access to the Internet, mobile phones and land lines and the trick is in answering the posers as calmly as possible, as the points will be given on the basis of the most stable pulse rate. Star India had bought this quiz format from Endemol last year.
