Scrabble Day celebrates the popular board game on the birthday of its inventor, Alfred Mosher Butts. Scrabble is a word game in which two to four players score points by forming words from individual lettered tiles on a game board marked with a 15×15 grid. The words are formed across and down in crossword fashion and must appear in a standard dictionary.
The game is sold in 121 countries and there are 29 different language versions. Approximately 150 million sets have been sold worldwide, and sets are found in roughly one-third of American homes. In 1938, American architect Alfred Mosher Butts created the game as a variation on an earlier word game he invented called Lexiko. (from Wikipedia and www.cute-calendar.com)
