English-language Scrabble is the original version of the popular word-based board game invented in 1938 by US architect Alfred Mosher Butts, who based the game on English letter distribution in The New York Times. The Scrabble variant most popular in English is standard match play, where two players compete over a series of games. Duplicate Scrabble is not popular in English, and High score Scrabble is no longer practised.
Although English is a worldwide language, the official list of allowable words and some tournament rules differ between territories.
