All Clued Up was a British game show based on the American version entitled The $1,000,000 Chance of a Lifetime. It aired on ITV from 16 April 1988 to 30 August 1991 and was hosted by David Hamilton. Format Like the American shows, two married couples, competed to solve word puzzles, which led to a master solution, in a game show combining the elements of Definition, Scrabble and Wheel of Fortune in North America. Toss-Up Puzzle The game begins with a toss-up puzzle. Each letter is revealed one at a time in a word except for the last letter, and whoever buzzed in with the correct answer won £10 and the right to pick two letters from a keyboard. Main Phrase Puzzle Like in America, the couple with a correct guess gets to choose two letters that are in the master puzzle (the UK called theirs the "Main Phrase Puzzle"). They'll choose letters from a keyboard. The keyboard contained all 26 letters, plus a star, which is used to represent markings other than letters such as apostrophes or hyphens. Letters that are in the puzzle are highlighted on the keyboard, plus, one letter that is not in the puzzle, which is called a "stinger", which if picked, causes the team to lose a turn. For each letter revealed in the word, £10 is added to a bank, and the team that correctly solves the puzzle wins the pot. After two letters are picked, if no correct guess is given, another toss-up puzzle is played. Each toss-up puzzle is a clue to the main phrase puzzle that's in play. Three rounds (sometimes more) were played with the value doubling to £20 later on in the game, and when the time-up buzzer signifies the end of the game, further screen puzzles and clues in normal game play would be declared null and void and the winning couple would advance to the bonus round. The runners-up however, take the money they won in the game; in the fourth and final series, however, the runners-up win the All Clued Up engraved pen set. For the fourth and final series, pounds became points. Bonus Round For the first series, the couple is placed inside an isolation booth; from series two to four, the couple stands in front of the keyboard instead. They choose one of three possible categories and have 60 seconds to guess six
