Perfection (game show)

The main game consists of three rounds.

In each round, the booth is turned off and the contestant has 45 seconds to answer four true/false statements. Once time runs out or all four statements have been played, the booth is turned on so the suspects can see the statements and answers, and the host asks if they would have responded differently. The number of correct answers is then revealed, but not specifically which ones. If the contestant has all four correct, he/she wins the round. Otherwise, the suspects are given a chance to change the responses they believe are incorrect, and can win the round by choosing correctly. The suspects win by default if all four of the contestant's answers are incorrect. If the suspects fail to change all answers missed by the contestant, neither side wins the round.

The winning side (if there is one) chooses two categories from a list of 12 to use in the final. If there is no winner, the two choices are carried over to the next round. In the case of no winner in the third round, the two sides alternate choosing categories until a total of six are in the final, with the contestant choosing first. The contestant's goal is to choose categories that will be easy for him/her, while the suspects make choices that they believe will be difficult for the contestant.

The final is played for a jackpot that begins at £1,000 and increases by that amount for every game in which it goes unclaimed.

With the booth turned off, the contestant answers six true/false statements, one per category in the order they were selected during the main game. There is no time limit, but the contestant may not return to a statement or change a response after committing to it. After all six answers are locked in, the booth is turned on and the suspects give their individual opinions of how many responses are correct, but not specifically which ones. Each may, at their discretion, offer to help in changing the answers they think are incorrect, in exchange for a portion of the money at stake. The contestant may accept no more than one offer, but is not required to do so. If the contestant does accept an offer, that suspect leaves the booth and joins the contestant onstage, and the two discuss which answers should be changed. The contestant's decisions in this respect are final.

If all six answers are correct, the contestant wins the jackpot and (if applicable) splits it with the helper according to their agreement; otherwise, the contestant wins nothing. The contestant leaves the show, as does the helper (if applicable), and enough new suspects are introduced in the next game to bring the pool back up to four.

The largest amount of money won on the show was £21,000 by Lynn on episode 23 of Series 5 broadcast on 22 October 2014, beating the £19,000 by Meg (£10,000) and Michelle (£9,000) on episode 57 of series 4 broadcast on 14 March 2014. . On 14 March 2014, Meg asked for Michelle's help after answering all of the final round questions, but wasn't sure on one question relating to In The Night Garden and both being unsure about the Indian sweet dish.

Lynn achieved perfection on her own, despite the usual suspects choosing all of her final round categories, with all of the usual suspects ruling themselves out from helping her, and despite being far from confident on a question about Konrad Adenauer being Chancellor of West Germany

Perfection in all three rounds was first achieved in the first game of episode 57 by a contestant named Pat, though she did not achieve perfection in the final round and thus did not win the jackpot. The following game in the same episode saw contestant Niall become the first to achieve perfection in all three rounds and the final, winning £7,000.

In the episode broadcast on 15 January 2014, a contestant called Detta achieved perfection in all three rounds and in the final. However, she accepted help from a usual suspect, who persuaded her to change one of her answers, therefore denying her the prize money of £3,000.

In the episode broadcast on 1 February 2013, a contestant called Sharon achieved imperfection in the first round, answering 0 correctly and allowing the usual suspects to win automatically. However, in the third round, she achieved perfection, scoring 4 out of 4. In the final, none of the usual suspects chose to come down and Sharon won the prize fund, achieving perfection and winning £1,000.

Aubrey and Jane of series 2 both hold the record for the longest run as a usual suspect before they were chosen. That record is 16 games. Under the current rules, this record cannot be broken, as players are allowed to take part in a maximum of eight games. Since this rule was introduced, six contestants – Ann, Emma, Phil, Beth, Sarah and Tracy – have played all of their eight games.
