Scrabble (game show) wild card contestants competed in semifinal matches on Monday through Thursday. The four winners advanced to the final matches that Friday, with a grand prize of $100,000 for the winner. With slight adjusting, this tournament format became the new permanent "Scrabble" format on December 29, 1986. As noted above, each episode now featured four contestants and two Crossword games worth $500 each. The champion played in the first Crossword, whose winner set a Sprint time for the second winner to beat, and the Sprint winner received $1,000 and took or retained the championship. With this format change, "Scrabble" became a
Scrabble CH in the "Collins Scrabble Words" lexicon. In 1938, American architect Alfred Mosher Butts created the game as a variation on an earlier word game he invented called "Lexiko". The two games had the same set of letter tiles, whose distributions and point values Butts worked out by performing a frequency analysis of letters from various sources, including "The New York Times". The new game, which he called "Criss-Crosswords," added the 15×15 gameboard and the crossword-style game play. He manufactured a few sets himself, but was not successful in selling the game to any major game manufacturers of the day.
