Mahjong (麻將, májiàng) is a four-player game of luck, memory, and nerve, played with 144 tiles and a rulebook that changes depending on which table you sit down at. Though the game feels ancient, it was invented in China in the mid-1800s, which makes it roughly the same age as the telephone. In the century and a half since, it has crossed the Pacific twice, survived a government ban in its home country, and splintered into regional variants played by hundreds of millions of people.

Its history runs through Qing dynasty money, a sea official who may never have existed, an American oil executive with a trademark, and a New York league that still mails out a new set of winning hands every spring.

The origins of mahjong

A persistent legend says Confucius created mahjong around 500 BCE, with the three suits standing for his cardinal virtues. It’s a good story, and it’s almost certainly false: no ancient text mentions the game, no artifact resembles it, and no tile older than the 1870s has ever been found. The legend seems to have been bolted on in the 1920s, when exporters discovered that an ancient pedigree helped sell tile sets to Western buyers.

The real ancestry is less romantic but far better documented. China had money-suited playing cards for centuries before mahjong appeared, including mǎdiào (馬吊), a Ming dynasty trick-taking game played with 40 paper cards. By the 1700s and 1800s, that tradition had produced a family of draw-and-discard games called pènghú (碰和), played with decks of 120 to 150 money cards, and their core loop of drawing, discarding, and collecting sets of three is recognizably mahjong. The game’s engine already existed on paper; it just needed better hardware.

Where mahjong was invented

That hardware arrived in the mid-to-late 1800s in the Yangtze River delta, the prosperous region around Ningbo, Shanghai, and Suzhou. Ningbo presses the strongest claim as the birthplace: the city’s Tianyi Ge museum credits Chen Yumen (陳魚門), a local official who supposedly moved the game from paper cards onto bone and bamboo tiles because cards kept blowing off the decks of ships. The story is probably too tidy to be entirely true, but the geography and the timing hold up.

They hold up thanks to an American customs official named George B. Glover, who collected two tile sets around 1872 and shipped one to the American Museum of Natural History in New York with a covering letter dated Shanghai, August 18, 1875. That set is among the oldest ever found, and it proves the game was already established in the region within a couple of decades of its supposed invention.

What the mahjong suits mean

The three numbered suits are a compressed history of Chinese currency. The Circles (筒, tǒng) are copper coins, the round “cash” minted with a square hole in the middle. The Bamboo tiles (索, suǒ) are the strings that threaded 100 of those coins together through the holes; look closely and the segments on each stick resolve into individual coins. The Characters (萬, wàn) stand for ten thousand coins, or 100 strings of 100, so a hand of mahjong quietly counts its way up from pocket change to a small fortune.

Winds, dragons, and the blank tile

The rest of the set is more symbolic. The four Winds (東南西北: east, south, west, north) correspond to the four seats at the table, and rotating through them over a session is built into the rules of nearly every variant.

The three Dragons settled into their current form by about 1890, though “dragons” is a Western label. Their Chinese name is 箭牌 (jiànpái), arrow tiles, and the theme is archery: the red 中 (zhōng) marks a hit on the center of the target, while the green 發 (fā) abbreviates 發財 (fā cái), “to strike it rich.” The white dragon (白板, báibǎn, “white board”) began as a completely blank tile, and makers only added a border once players needed to tell it apart from an unengraved spare, a real problem when every set was carved by hand.

Many sets round things out with 8 bonus tiles, 4 Flowers and 4 Seasons. The flowers are usually the Four Gentlemen of Chinese painting: plum, orchid, bamboo, and chrysanthemum.

The history of the name

Across much of China the game is still called máquè (麻雀), “sparrow,” and Japan borrowed those same characters (read mājan). The usual explanation is that shuffling tiles sounds like a tree full of arguing sparrows, and the name goes back as far as the game itself: Glover’s 1875 letter lists his set under a title meaning, roughly, “snatching the house sparrow.”

The bird survives in the tiles, too. The 1 of Bamboo almost never shows a stick, because carvers treated it as their signature piece. That’s why it’s usually the most ornate tile in the set, and why the bird on it is frequently, and confusingly, a peacock.

The 1920s mahjong craze

Mahjong owes its global reach to Joseph Park Babcock, a Standard Oil executive who learned the game while living in Shanghai. He simplified the rules for American players, trademarked the spelling “Mah-Jongg,” and in 1920 published a slim rulebook that became known as the red book for its cover.

It lit the fuse on one of the strangest fads of the decade.

From roughly 1922 to 1924, American department stores couldn’t keep sets in stock, Shanghai workshops ran flat out to meet the demand, and cattle shinbones from American stockyards were shipped across the Pacific to be carved into tiles and shipped straight back. Eddie Cantor even had a hit novelty song about it (“Since Ma Is Playing Mah Jong,” 1924). The fad cooled within a few years, as fads do, but the game itself never left.

American mahjong and the annual card

What the craze left behind was a mess of contradictory house rules, and the cleanup produced a whole new variant. In 1937, a group of women in New York founded the National Mah Jongg League to standardize the American game, and their fix was clever: print the valid winning hands on a card, and change the card every year. The League also added Jokers and the Charleston, a ritual pre-game exchange of tiles between players.

Nearly 90 years later the annual card still arrives each spring, and American mahjong, kept alive for decades largely by Jewish-American women, is booming again.

Riichi mahjong in Japan

Japan met the game around 1909, when the first sets were imported from China, but the real spark came in 1924, when a soldier named Saburo Hirayama opened Tokyo’s first mahjong parlor and school. Clubs multiplied, a national federation followed in 1929, and over the next few decades Japanese players tuned the game into something sharper. The riichi rules published in 1952 added the variant’s signature move, a declared bet that locks your hand in exchange for a shot at a bigger score, and the modern game solidified in the 1960s alongside a professional scene.

Today riichi is arguably the most strategically deep variant, and the scale of its home market is hard to overstate: around 2008, Japan had an estimated 7.6 million players and nearly 9,000 dedicated parlors. Online clients like Tenhou and Mahjong Soul have since carried it worldwide.

Mahjong in modern China

Back in China, the 20th century was rougher. In 1949 the new People’s Republic banned mahjong as a gambling game, and it stayed suppressed through the Cultural Revolution. When the ban was lifted in 1985, the game snapped back into daily life almost immediately, and official rehabilitation followed.

In January 1998, China’s sports administration certified mahjong as the country’s 255th official sport and published the Mahjong Competition Rules (MCR), an 81-pattern scoring system designed for tournament play with the gambling stripped out. The first World Mahjong Championship under those rules was held in Chengdu in 2007.

The major mahjong variants

There has never been one mahjong, and the variants can feel like different games wearing the same tiles. Hong Kong old style is the fast, widely played classic; riichi is Japan’s deep strategy game; MCR is the international tournament standard; and American mahjong runs on the League’s annual card. Regional China keeps its own flavors too, like Sichuan’s 血战到底 (xuèzhàn dàodǐ, “bloody battle to the end”), in which the hand keeps going until three of the four players have won.

One more branch deserves a mention, because it confuses everyone: mahjong solitaire, the tile-matching computer game. Brodie Lockard, a Stanford student who had been paralyzed in a gymnastics accident, built it on the PLATO system in 1981, typing the code with a mouth stick. Activision released it as Shanghai in 1986 and sold roughly 10 million copies, which is why so many people picture a matching puzzle when they hear the word mahjong. It shares the tiles with the real game, and little else.

Mahjong today

A century after the first craze, mahjong is having another moment. The mahjong scene in Crazy Rich Asians (2018) pulled the game back into pop culture, the pandemic sent millions of new players to online riichi, and Eventbrite reported mahjong event searches up 365% between 2023 and 2024. Every version of the boom comes back to the same picture, though: four players, a wall of tiles, and everyone reading the discards. That’s the table IRL Mahjong was built for. It keeps the score so you can keep playing.
