This is a deceptively difficult quiz. If it happens to be on I don't turn over and enjoy trying to get some of the answers.
Each question has a list of 10 correct answers. The difficulty of the questions vary hugely.
Out of a team of 5 only the captain is guaranteed a place in the final round. To get to the final round each team member must supply at least 5 correct answers in an individual round. The host sets the question and the captain chooses who in the team is best to answer, but only one round each. Each person can give one wrong answer but another wrong answer will see them eliminated. The team captain has a couple of chances to overrule an answer they think is wrong, plus a couple of opportunities for the team members to nominate a teammate to supply an answer should they need some inspiration. The more correct answers the more money in the prize fund, a total of £125,000 is possible. The team captain is guaranteed a place in the final round, they still need to get 5 answers to start adding to the prize fund. Instead of adding to the price fund the captain can choose to bring back someone who has been eliminated to join them in the final round.
The final round is next to impossible. One (usually very complicated) question is posed, again a list of 10 answers. This time, starting with the team captain, each player takes it in turn to give an answer. Give a wrong answer and that person is eliminated. Only all 10 correct answers will win the money - there are only 10 answers. I have seen many episodes and only recall one team winning the final round.
I'm now off to research how many winners there have actually been.....
