Wheel of Fortune is a British television game show created by Merv Griffin. Contestants compete to solve word puzzles, similar to those used in Hangman, to win cash and prizes. The title refers to the show's giant carnival wheel that contestants spin throughout the course of the game to determine their cash and/or prizes. The programme aired between 19 July 1988 and 21 December 2001 and was produced by Scottish Television (STV) for the ITV network - having effectively replaced Now You See It as STV's prime time game show offering for the ITV network. It mostly follows the same general format from the original version of the programme from the United States, with a few minor differences.
