It's Not What You Know

It's Not What You Know is a game show hosted by Chris Tarrant, which aired on the British digital TV channel Challenge from 28 April to 6 June 2008.

Gameplay

Phase one

The game is played by a team of two. To start, each team is given three games to play, labelled A, B or C. To help them, one celebrity "expert" and their specialist subject from each game is displayed. The players must choose one of the games and, once they have, the other four celebrities and their specialist subjects in the chosen game are revealed. Each game contains 15 questions with each question being specific to one of the celebrity's specialist subject.

Questions and answers

Each question comes up with four possible answers; these answers are shown to all but the specialist celebrity. After the right answer is displayed, the players then decide on which celebrity was "stumped". Once the players have chosen, their chosen celebrity gets "locked in". Afterwards, the celebrities who got the question correctly and those were stumped are identified. Following, the players' chosen celebrities are identified; if the celebrity chosen was one of the non-specialist celebrities and were stumped, the players’ jackpot increases by the prize amount of the level they are on. If they were the specialist celebrity and were stumped, the players also move up a level with a potential for winning higher amounts of money. The studio changes colour to reflect this.
Level 1 is played for £1,000 per question. This amount increases through each level to £5,000, £10,000, £15,000 and £25,000.

Back to zero

If the players make an incorrect guess, they lose what they have accumulated so far. They will still be allowed to continue playing at their current prize level, restarting their jackpot from zero. However, if they make an incorrect guess twice in a row, they'll go down a level.

Passing

If at any point the players are uncertain of correctly guessing a stumped celebrity, they can pass on the question they are on and keep their winnings safe, but they cannot pass on Question 15 because "that would be too easy", stated by Chris Tarrant.

Final phase

The players then get offered between 20% and 50% of how much they had amassed in the game after Question 14. If the players accept the offer, they'll take home with them the amount of money offered and still go on to Question 15, just to see what would have happened. If the players reject the offer, they'll go on to Question 15 and try to make a correct guess. If they select a stumped celebrity, their jackpot goes up by £1,000, £5,000, £10,000, £15,000 or £25,000 and the players take home with them whatever they have banked. If they select a celebrity who answered the question correctly, they'll leave empty-handed.
