It's Not What You Know (also known as Chris Tarrant's 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.



Phase one

The game is played by a team of two (friends, relatives, etc.). 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

The first question comes up with four possible answers; these answers are shown to all but the specialist celebrity. After the correct answer is displayed (it does not matter if the players got it right or wrong), the players then decide on which celebrity was "stumped" (got the question incorrect; there were at least four occasions of the specialist celebrity being stumped). Once the players have chosen, their chosen celebrity gets "locked in". After that stage, the celebrities who got the question correct 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 to £1,000. If they were the specialist celebrity and were stumped, the players progress up a level with a potential for winning higher amounts of money and the studio changes colour (level 1 is purple, level 2 is yellow, level 3 is blue, level 4 is green and level 5 is left unknown because no couple has reached that point in the game).

The players who chosen the stumped specialist celebrity then play for £5,000. Subsequent correct guesses by the players will increase to £10,000, then £15,000, then to the maximum £25,000.

Back to zero

If the players make an incorrect guess (meaning that their chosen celebrity, specialist or non-specialist, got the question right), 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 (unless they are still on the first level).


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 (they are only allowed to pass on a question once, though), but they cannot pass on Question 15 (the last question) 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 (depending on which ever level they were on) 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.

<i>Temptation</i> (Australian game show) Australian television game show

Temptation was an Australian game show which premiered on the Nine Network on 30 May 2005. Hosted by Ed Phillips and Livinia Nixon, the show was a remake of Sale of the Century, which aired on Nine in the same timeslot for more than twenty years between 1980 and 2001. Temptation had the same general format of its predecessor, but with several new features and a deemphasis on the "shopping" aspects of the endgame. The show ran until 30 November 2007, when it was placed on hiatus by the network following strong competition from game show Deal or No Deal on the rival Seven Network; during the hiatus, Nine filled the timeslot with episodes of the American sitcom Two and a Half Men. When Ed Phillips made an appearance on The NRL Footy Show he announced "maybe summer" would be the return of the show. This statement was accurate, as Temptation returned for a shortened fourth series from 1 December 2008 with unaired episodes which were recorded during 2008. During that time, Ed Phillips was dumped by the Nine Network after his contract expired in November, and Temptation never returned to the schedule. After 23 January 2009, when the show's final episode aired, all Temptation websites were removed, and Two and a Half Men returned to Channel Nine's 7:00pm schedule.
