Mah Jongg arrived in America by steamship in the early 1920s, found a home in New York apartments and Catskill resorts, was nearly killed by a flood of incompatible rule books, and was rescued in 1937 by a group of Jewish women in Manhattan who decided enough was enough.
A hundred years later, the game they standardized is played weekly by hundreds of thousands of Americans, sells out cruise ship tournaments, and has its own annual card that drops every spring like a fashion season.
Here is the long version, in short form, of how American Mah Jongg became the game it is today.
Where Did Mah Jongg Originally Come From?
Mah Jongg as a tile game emerged in mid-nineteenth-century China, almost certainly in the Yangtze River region, evolving from older Chinese card games that used number sequences and matched sets. By the late Qing dynasty, the game was widespread in Chinese cities, played by men in tea houses and increasingly at home. The version played in 1900s Shanghai had 144 tiles, no jokers, and rules that varied by region, the same problem that would later define its American history.
Western travelers first encountered the game seriously in the 1910s. A few enterprising importers, the most famous of whom was Joseph Park Babcock, an oil company executive based in Shanghai, translated the rules into English in 1920 and brought sets to the United States the following year.
Babcock's simplified rule set, sold under the brand name Mah-Jongg by the Parker Brothers and the Milton Bradley company, was the version that exploded in America in 1922 and 1923.
Why Did Mah Jongg Become a 1920s American Craze?
American Mah Jongg in the early twenties was a phenomenon. By 1923, an estimated fifteen million American homes owned a set. Department stores ran out of tiles. The game was discussed in popular magazines, parodied in vaudeville, and adopted by the same upper-middle-class urban women who were also reshaping the bridge tables of the era.
Several forces converged. The 1920s combined unprecedented disposable income for the urban middle class, a fascination with all things “Oriental,” which was a marketing label of the era and not a description we would use now, and a generation of women who had time, household help, and were looking for social activities that took them out of the house. Mah Jongg fit all three currents.
The boom was loud and fast, and like most fast booms, the bust was equally loud. By the late 1920s, the game had peaked, prices had collapsed, and the major manufacturers had moved on to other products. By the Great Depression, Mah Jongg was largely associated with older players and small enthusiast circles, not the wider American household.
How Did the National Mah Jongg League Save the Game?
The death of the 1920s boom was not, as is sometimes said, because Americans got bored. It was because the rules were a mess. Every region, every neighborhood, and sometimes every table played a different version. There were dozens of competing rule books on the market, each backed by a different importer.
Sit down at a friend's table in Boston, and the hands you had memorized in New York were not legal. Players got tired of it and stopped playing.
In 1937, a group of Mah Jongg enthusiasts in New York City decided to standardize the American game once and for all. The founding members, predominantly Jewish women from the city's Upper West Side, established the National Mah Jongg League.
The League's first published card listed the legal winning hands for that year, and every member could buy the card and play to those hands knowing every other member was playing the same way. The chaos ended within a few seasons.
That decision shaped everything that came after. The NMJL has published a new card every year since, with the exception of brief disruptions during World War II. The card has become not just a list of legal hands but the central ritual of American Mah Jongg.
Players gather in March or April for the new card release. Groups switch over together. Strategy and conversation in the spring revolve around what the new year's hands favor. Players preparing for the current season can order the 2026 NMJL card.
How Did American Mah Jongg Become Strongly Associated With Jewish Women?
The association is real, well-documented, and worth understanding because it shaped the culture and community of American Mah Jongg for nearly a century.
The first wave of American Mah Jongg adoption in the 1920s cut across many demographics, but the League's founding in 1937 was led by Jewish women in New York, and the early membership skewed heavily Jewish.
Several social forces sustained that demographic concentration through the mid-twentieth century. American Jewish women, particularly in the urban Northeast, had developed strong networks of weekly social play through synagogues, sisterhoods, and Hadassah chapters. Mah Jongg fit naturally into those existing social structures.
Catskill resorts featured Mah Jongg as part of summer programming. By the 1950s and 1960s, the weekly Mah Jongg game had become part of the cultural fabric of American Jewish family life.
The demographic has broadened significantly since the 1990s, and the game today is played widely across cultural backgrounds. However, the historical association is a real part of why the game has the community infrastructure it has and why the National Mah Jongg League card remains, in many ways, an artifact of that founding history.
The Jewish Museum Milwaukee's history of the National Mah Jongg League card offers additional information about the women and traditions behind the card.
What Has Changed in American Mah Jongg Since the 1980s?
Three major shifts have reshaped the game over the past forty years.
Tournament Infrastructure
In 1986, the National Mah Jongg League and Mah Jongg Madness ran their first joint Mah Jongg Tournament at Sea. That single event grew into the modern tournament ecosystem: cruise tournaments, regional weekend tournaments, an annual National Convention every March in Las Vegas, and a network of professional tournament directors who run play year-round.
A Second Generation of Players
The original 1937 generation passed the game to their daughters and granddaughters. The 1990s and 2000s saw a wave of younger players, including women in their forties and fifties, returning to the game after watching their mothers and grandmothers play.
The 2010s and 2020s added another wave: men, younger players, and players outside the historical demographic, often drawn in by a friend or family member.
A Design and Craftsmanship Renaissance
For decades, the standard American Mah Jongg set was functional and plain. The last fifteen years have seen a strong design renaissance, including designer tile sets in jewel tones, hand-finished racks, neoprene mats with custom artwork, and embroidered carrying bags.
The game has reclaimed the visual presence it had in 1920s catalogs, but executed to modern craft standards. Today's players can choose from complete sets or build a personalized collection using Designer Series Mah Jongg tiles.
Where Does the American Game Stand Today?
By recent estimates, more than half a million Americans play American Mah Jongg regularly, with a much larger occasional-player base. The National Mah Jongg League sells hundreds of thousands of cards each year. Tournament cruise sailings sell out months in advance.
New tile-design houses, The Charleston Club among them, have built businesses around the renewed interest in heirloom-quality equipment.
A hundred years after Joseph Park Babcock unloaded the first shipments in San Francisco, the game he imported still sits at thousands of kitchen tables every week. It is played to a card that updates every spring by a community that organized itself in 1937 and never stopped.
Frequently Asked Questions About American Mah Jongg History
When was the National Mah Jongg League founded?
The National Mah Jongg League was founded in 1937 in New York City by a group of Mah Jongg enthusiasts, predominantly Jewish women, who wanted to standardize the American game and end the chaos of competing regional rule books. The League has published a new card almost every year since.
Is American Mah Jongg different from Chinese Mah Jongg?
Yes. American Mah Jongg uses 166 tiles, including eight jokers and eight flowers, is played according to the annual NMJL card, and includes the Charleston passing ritual that does not appear in traditional Chinese Mah Jongg. Chinese Mah Jongg uses 144 tiles and follows older traditional rules without a yearly hand-set update.
Who is Joseph Park Babcock?
Babcock was an American oil company executive based in Shanghai in the 1910s and 1920s. He simplified and translated the Chinese rules into English in 1920 and licensed the brand name Mah-Jongg to Parker Brothers and Milton Bradley, sparking the 1920s American craze.
Why does the NMJL card change every year?
The card was originally annual to provide variety, but the modern reason is competitive. Changing hands annually prevents stale memorized play, keeps strategy fresh, and gives every spring a structured relearning event. Most groups switch over on April 1 when new cards arrive.
How many Americans play Mah Jongg today?
Recent estimates place regular American Mah Jongg players in the hundreds of thousands, with a significantly larger casual or occasional base. The National Mah Jongg League sells hundreds of thousands of cards annually, which gives a rough lower bound on active players.
