America’s Embrace: The History of American Mahjong

By the early 20th century, mahjong had traveled beyond China’s borders, captivating players across Asia and eventually reaching the Western world.
It is believed that mahjong arrived in the United States in the 1920s, carried by merchants, diplomats, and travelers who had encountered it abroad — and American society embraced it with remarkable enthusiasm. For a time, mahjong became one of the country’s most fashionable pastimes.

When mahjong arrived in America, it did not simply transplant itself — it transformed. The game that had crossed the Pacific was embraced, reimagined, and ultimately reshaped by a new community that would make it entirely their own.

In the 1930s, a group of Jewish American women in New York City founded the National Mah Jongg League, standardizing the rules of American mahjong and introducing the innovation that would come to define it: the annual card. Each year, the NMJL releases a new set of hands — the combinations of tiles required to win — keeping the game ever-evolving and its community deeply engaged. That card has been issued every year without interruption since 1937.

American mahjong became a cornerstone of Jewish American social life, passed from mothers to daughters across kitchen tables and card rooms for generations. It was — and remains — more than a game. It is a tradition, a gathering, a ritual of connection. The NMJL built not only a game but a community, and with it a legacy of philanthropy and purpose that continues to define the American mahjong world today.

Over the decades, American mahjong has grown well beyond its original community, welcoming players of every background who have discovered the game's unique combination of strategy, chance, and camaraderie. Today it is played in living rooms, community centers, country clubs, and beachside cabanas across the country.
