the player has a set of lifelines that they may use only once to help them with a question, as well as two "safety nets" – if a contestant gets a question wrong, but had reached a designated cash value during their game, they will leave with that amount as their prize. While the first few questions are generally easy, subsequent ones might prompt the host to ask if the answer they gave is their "final answer" – if it is, then it is locked in and cannot be changed. If a contestant feels unsure about an answer and does not wish to play on, they can walk away with the money they have won, to which the host will ask them to confirm this as their final decision; in such cases, the host will usually ask them to state what answer they would have gone for, and reveal if it would have been correct or incorrect. Original format During the British original, between 1998 and 2007, the show's format focused on fifteen questions. The payout structure was as follows (questions at guaranteed levels are highlighted with a bolded text): Between 2007 and 2014, the number of questions was reduced to twelve; the overall change in format was later incorporated into a number of international markets over a period of four years, including the Arab world, Bulgaria, the Netherlands, France, Poland, Spain, and Turkey. The payout structure, as a whole, was subsequently changed as a result, with the second safety net relocated to £50,000 at question 7 (questions at guaranteed levels are highlighted with a bolded text): The game show's revival for British television in 2018 reverted to the original arrangement used before 2007, but with one notable difference, in that the second safety net was made adjustable – once a contestant reached £1,000, the host asked them, before giving the next question, if they wished to set the next cash prize amount as the second safety net, with this allowing them to set up as high as £500,000 in their game as a result. US format The original US version premiered on ABC in August 1999 as part of a two-week daily special event hosted by Regis Philbin. After this and a second two-week event aired in November 1999, ABC commissioned a regular series that launched in January 2000 and ran until June 2002. The syndication of the game
