A pair of contestants are given a chance to win up to £100,000 by answering a series of multiple-choice questions in two rounds. All questions require the contestants to select the answer that falls either first or last in a particular sequence (e.g. the first actor to portray a comic book villain in a movie, or the bingo call that corresponds to the lowest number).
Twenty-four numbered envelopes are presented, each containing a different cash amount ranging from £100 to £100,000. The first round consists of six questions, each with four answer choices. Before each question, the contestants select four envelopes. Once the question has been asked, these envelopes are secretly assigned so that the one with the highest value corresponds to the correct answer, the second-highest to the next closest answer, and so on. The contestants eliminate one answer at a time, and the envelope corresponding to each is opened and its amount eliminated from play. The correct answer is then revealed, and the last envelope is given to the contestants without being opened.
The second round consists of five questions. Once a question has been asked, the remaining envelopes are secretly assigned in reverse order compared to the first round, so that the correct answer is paired with the lowest value still in play. The contestants select one answer, whose envelope is opened and eliminated, and the correct answer is then revealed. The first question has six answers, and each subsequent question has one fewer until the fifth question, which has only two answers. After all five questions have been asked, the contestants win the amount in the last remaining envelope.
The twenty-four money amounts are £100, £500, £1,000, £2,000, £3,000, £4,000, £5,000, £6,000, £7,000, £8,000, £9,000, £10,000, £12,000, £14,000, £16,000, £18,000, £20,000, £22,000, £25,000, £30,000, £40,000, £50,000, £75,000, and £100,000.
