Impossible (stylised as !mpossible) is a British television quiz show created by Hugh Rycroft and produced by Mighty Productions for BBC One. Hosted by Rick Edwards, the show has a maximum prize of £10,000 and features questions in which some answer choices are "impossible" or inconsistent with the given category.

Episodes of Impossible are also seen in the United States on the over-the-top internet television services Plex, Xumo and The Roku Channel, with each looping episodes 24 hours a day on its own dedicated streaming channel.

With the exception of Round 2 (see below), all questions used on the show are multiple-choice with at least one answer each of three different types: correct, wrong or "impossible". The impossible answers cannot be correct and are distinguished by being inconsistent with the premise of the question. For example, if the question were "Oslo is the capital of which European country?", the choices could be:

• Serbia – wrong (its capital is Belgrade)
• Norway – correct
• Mauritania – impossible (It's a country in Africa)

On each episode, a pool of contestants competes through two rounds until one is left to play for either the £10,000 jackpot or a smaller daily prize pot built up during the course of the game. Contestants leave the show after playing the £10,000 question once whether they win or not. With the exception of the last episode of each series, players who fail to reach the £10,000 question for any reason return on the next episode as long as they have not reached the end of their eligibility.

The size of the pool and the contestants' time on the show have occasionally changed. In Series 1, 30 contestants competed across all 15 episodes. The entire pool was replaced after every ten episodes in Series 2 and 3 and after every five episodes from Series 4 onward. The pool was 24 contestants in Series 2 through Series 4 and 21 in Series 5. Also, in Series 1, contestants remained on the show until either winning the £10,000 prize or making two unsuccessful attempts at it, rather than one as in all subsequent series. Series 8 had 12 contestants instead of 21 due the coronavirus pandemic social distancing guidelines.

During Series 1 to 3, contestants who left the show were replaced by new ones to keep the pool at a constant size. Starting with the Series 4, the departing contestant is not replaced, leaving their seat empty.

This round is played three times, with each playing split into two halves, a qualifier and the grid, to choose a contestant for the Final. The scores are set to zero at the beginning of each Qualifier.

In the Qualifier, the host asks five multiple-choice questions; each with three answer options. Contestants secretly lock in their guesses and earn one point for each correct answer. Wrong answers leave the score unaffected, but an impossible answer, or a failure to answer within the time limit, eliminates the contestant from the game. If exactly one player remains uneliminated after a question, the qualifier is immediately halted and that player qualified for the Grid. However, if all remaining contestants are eliminated on a single question, the entire pool is brought back into play. After the fifth question, the high scorer advances to the grid; any ties for high score are broken in favour of the contestant who took the shortest total time to lock in their answers.

For the Grid, the high scorer chooses one of four categories and is shown nine answers: one correct, three wrong and five impossible. After hearing the first half of a question, they choose five answers they believe to be impossible; each successful choice adds £100 to the daily prize pot and is removed from the board. The host then reads the second half of the question with all chosen non-impossible answers returned to play and the contestant must choose the correct answer in order to advance to the Final. Choosing a wrong answer gives the runner-up/last player who was eliminated from the first half a chance to find the right answer and advance; however, if this contestant chooses a wrong or impossible answer, the high scorer moves ahead. If any impossible answers remain on the board and the high scorer chooses one, they are eliminated and the runner-up gets a turn; if they fail to choose the correct answer, the host begins working down through the next-highest scorers until one of them does so.

Categories are removed from the list of four as they are chosen leaving three options in the second playing and two in the third. The maximum daily prize pot is £1,500; this is accumulated by eliminating all five impossible answers in every playing of the grid, while the smallest possible daily prize pot is £300. Contestants who advance to the Final sit out all subsequent playings of the Qualifier and Grid.

If a Qualifier begins with only one contestant left in the pool, they must still give a correct answer in order to advance to the Grid.

The 3 remaining contestants compete directly against one another answering a series of open-ended questions on the buzzer. Each is given 10 lives to start the round; a correct answer takes one life from both opponents while a wrong answer takes one from the contestant who buzzed in. Some of the questions are themselves impossible (e.g. "In which decade of the 20th century was Pablo Picasso born?" – he was born in 1881, during the 19th century). Correctly identifying an impossible question costs both opponents two lives; however, if a contestant either tries to answer an impossible question, incorrectly identifies a possible question as impossible, or does not answer immediately after buzzing-in, they lose two lives. Contestants who lose all their lives are eliminated from the game; the last one remaining advances to the £10,000 Question.

The last remaining contestant is asked one question in a randomly chosen category and shown nine answers; three each of correct, wrong and impossible. The contestant has 10 seconds to choose three answers and wins the £10,000 jackpot if all three are correct. They win the daily prize pot if any of their choices are wrong but none are impossible and nothing at all if they choose an impossible answer.

If a blind or visually impaired contestant reaches this round, the host reads one answer at a time and the contestant says "yes" or "no" to indicate whether they believe it to be correct.

During Series 1, contestants who missed the question were asked a second one under the same rules. This format was dropped at the start of Series 2 giving only one chance to win any money.

The format was further altered in Series 4 in that the departing contestant was no longer replaced leaving that seat empty for subsequent episodes. The batch of contestants would also stay for one week instead of two like in previous series.

The jackpot is presented onstage as a giant exclamation mark containing 10,000 £1 coins. When a contestant wins it, a hatch in the bottom opens and the coins drain into a hopper underneath.

On 20 February 2018, it was announced that Impossible would be launching a primetime Celebrity version which began to air in August that year. This version follows the same rules as the Regular version with two changes:

• The pool consists of 18 celebrities; each are playing for a charity of their choice.
• If a celebrity gives an impossible answer during the Final, the daily prize pot is cut in half and donated to their charity.^[2][3]

The official Impossible app for iOS and Android was released by Barnstorm Games on 28 August 2019.
