Season 1

Lee Mack hosts the first of five special editions of the quiz in which the prize pot that is not won on one show is carried over to the next day's edition, meaning there could be up to £500,000 to be won. As usual, 100 contestants begin every show, but those who make it through to the final question return the next day to play the quiz again.
