The show features a competition in which contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel. The original daytime version aired on NBC from January 6, 1975, to June 30, 1989. It was on CBS from July 17, 1989, until January 11, 1991, and returned to NBC from January 14 to September 20, 1991, when it was canceled permanently. The daily syndicated version of the series premiered on September 19, 1983.
