No Win No Fee
The only quiz show where the host receives no fee! He only gets paid if no contestant wins - in which case he gets to take the prize money home. But, it's not just an ordinary Q&A quiz - it's a show where based on your judgement of character and even without having answered any questions, you could walk away with the cash prize.
The contestants only meet on the day of the recording but in order to stay in the game they must be able to predict the answers of their opponents. A game of bluff and judgement of character, and where the host is happy to say you're out!, because he then gets the prize money.
