"Think Tank" is a quiz show where a regular cast of contributors aim to help three contestants through a series of questions hoping they can win thousands of pounds.
Ahead of each show, the regular cast from across the nation answer hundreds of general knowledge questions. Their answers form the quiz and will hopefully prove more of a help than a hindrance as the three contestants try to answer the questions correctly.
After their knowledge has been tested to the max, the winning contestant then faces ‘Question: Impossible', which stumped the whole Think Tank team. Using their wrong answers to eliminate obvious errors, can the contestant go one better and win a huge cash prize?
