The game traveled west in the early 20th century and enjoyed a flash in the pan around 1920, when Joseph Park Babcock, an Indiana native who had learned the game while in China, created rules for a simpler, streamlined version that was easier for Westerners to play. Abercrombie & Fitch started importing mahjong sets and by some accounts sold 40,000 sets over a decade. Milton Bradley and Parker Brothers got in on the action, too, but the fad had significantly simmered down by the Great Depression. While there are several active national mahjong organizations in the U.S. today, none holds an American-style national tournament.
