Taiwan Mahjong: Grandma Won't Teach You, but Celebrity Mahjong Will

Taiwan's 16-tile mahjong uses 144 tiles, 8 flower tiles, a scoring system more complex than anywhere else in the world, and one unwritten pedagogical method: elders play in front of you but never explain. You learn only by being scolded. In 2001, IGS released Celebrity Mahjong (明星三缺一), letting the voices of Wu Zong-xian and Wang Cai-hua keep you company while you practiced. The game has been alive for over twenty years and remains a cash machine in Taiwan's mobile gaming market. But what it truly accomplished is something deeper than revenue: it transformed a culture that was passed down only in whispers at the tile table into something anyone could figure out on their own.

The Table at Chinese New Year

Lunar New Year, second day. Grandma's house. Adults finish eating, dishes still unwashed, and the square table is already out.

Four people settle in. Tiles clatter onto the table; the sound of shuffling drowns out the holiday song on the TV. The children are shooed to the living room to watch cartoons — but you peek through the door crack: Grandma draws a tile, doesn't even look at it, tosses it away, and three seconds later calls "win." The other three start counting money.

You ask how much she won. She says "three base, six points." You ask what that means. She says children should be seen and not heard.

This is the mahjong origin story for most Taiwanese people. No textbook, no rulebook. Taiwan's 16-tile mahjong knowledge has been transmitted for decades by one extremely primitive method: sit beside and watch until you understand. Ask too many questions and you get on people's nerves.¹

The World's Most Complex Mahjong

Taiwan plays 16-tile mahjong — different from every other mainstream mahjong in the world.

Japanese mahjong uses 13 tiles, has the "riichi" system, and the rule "no scoring combination, no win" — the structure is clean. Chinese national standard mahjong unifies official rules with 81 winning tile patterns, like an exam reference book. Hong Kong mahjong is also 13 tiles, with simple scoring and fast pace.²

Taiwan's 16-tile? Three extra tiles per hand — combinations explode. Among 144 tiles are the suited tiles (bamboo, circles, characters) and honor tiles, plus 8 flower tiles (Spring, Summer, Autumn, Winter, Plum, Orchid, Bamboo, Chrysanthemum). Flower tiles add to your score directly; assembling specific combinations can win the game outright. Collecting all 8 flowers (known as "Eight Immortals Crossing the Sea") scores 8 points — practically popping champagne.³

But what truly bewilders outsiders is the point system.

Taiwan mahjong's scoring unit is the "tai" (台, point). The winning formula for each hand is: (base + points) × 3. Sources of points are wildly varied: self-draw adds a point, clean hand adds a point, flower tiles add points, specific tile patterns add points. A clean hand self-draw scores at least 3 base and 10 points — the most traditional big hand.⁴ Each table can also add or modify "house rules" — how consecutive banker wins are scored, how many points for special hands — all oral agreements written nowhere.

Curator's Note
Taiwan mahjong rules have never been standardized. Japan has the Japan Mahjong League. China has National Standard Mahjong. But Taiwan 16-tile's "official rules" are simply "our house rules." Every family has slight variations in point calculation — and this itself is part of the culture: rules are, at bottom, the concrete existence of family memory.

Three Founders Who Were Card Sharks

The company that made Celebrity Mahjong, International Game System (IGS/鈊象), has a founding story that reads like a hand of cards itself.

In 1989, three classmates from Taiwan Institute of Technology (now National Taiwan University of Science and Technology) decided to start a company together. Chairman Li Ke-zhu, General Manager Jiang Shun-cheng, and Commercial Arcade Business Group GM Chen A-jian had been friends and card partners since their student days. Jiang had been a hardware engineer at Philips; Chen was doing firmware at Sampo — both well-compensated electronics professionals. Li invited them to join; both voluntarily took pay cuts.⁵

In the early startup days, they pulled all-nighters on arcade machines during peak season, and during the off-season the three of them played mahjong and ping-pong. IGS started out making commercial arcade machines; in 1996 they developed their own 2D game platform, the PGM (PolyGame Master), becoming the only game platform manufacturer in Asia outside Japan with a proprietary arcade hardware system.⁶

But what turned IGS from an arcade manufacturer into a "gaming stock king" was a very Taiwanese decision: make mahjong into a computer game.

2001: Wu Zong-xian Teaches You to Play

In 2001, IGS released the PC version of Celebrity Mahjong (明星三缺一). The concept was intuitive to the point of genius: hire Taiwanese celebrities to do the voicework, so you feel like you are playing against stars.⁷

Wu Zong-xian, Tang Cong-sheng, Wang Cai-hua, Zheng Yu-ling — across two generations of versions, over 14 celebrities participated in recording. Each character had its own voice package: taunts when claiming a tile, bragging when winning, wailing when dealing the wrong tile. Wang Cai-hua's laughter and Tang Cong-sheng's impressions turned the act of playing mahjong from "a quiet mathematical calculation" into "a table full of people trading insults."⁸

The second generation was released in 2002, distributed by Soft-World International, with 120,000 units shipped to both sides of the strait and 35,000 first-run copies in Taiwan. In that golden era of internet cafes, Celebrity Mahjong occupied screens alongside Counter-Strike and StarCraft.⁹

But Celebrity Mahjong accomplished one thing those games could not: it taught non-players how to play mahjong.

The game came with complete rules for Taiwan 16-tile mahjong built in. Every hand scored itself automatically; when you won, it listed how many points you scored and how each point was earned. No need for Grandma to explain — the computer told you directly: "Clean hand + self-draw + 2 flower tiles = 5 points." For an entire generation that grew up in front of a DOS or Windows screen, Celebrity Mahjong was the mahjong textbook.

Grandma's teaching method: "Children should be seen and not heard." Celebrity Mahjong's teaching method: "If you play wrong, Wang Cai-hua will laugh at you." Both work — but the second one won't make you cry over Chinese New Year.

Vitality: From PC to Mobile

IGS has come close to dying twice in its history.

The first time was 2000: China cracked down on the gaming industry, commercial arcade orders collapsed, and IGS faced its first-ever loss. The second time was 2013: mobile games surged, the PC gaming market contracted, and IGS's earnings per share fell to just NT$1.7.¹⁰

Both times they survived through transformation. In 2000, they pivoted to PC online games and established an Online Business Division. In 2013, they redeployed two-fifths of their workforce into mobile game development; after initial failures across various genres, they refocused on card and gambling-style games, finding their core competitive advantage again.¹¹

Celebrity Mahjong pivoted with them — from standalone to online to browser-based, then to mobile in 2017. The mobile version was listed in Apple App Store Taiwan's top 10 games in both 2017 and 2018.¹²

By 2024, IGS set an all-time high in annual revenue, with annual and monthly revenue records broken repeatedly and substantial employee bonuses.¹³ Listed on the OTC market under code 3293, it is known as Taiwan's "gaming stock king."

Celebrity Mahjong's Taiwan payment rate is approaching its ceiling. But IGS has opened new markets through Southeast Asian licensing and overseas platforms.¹⁴ A company that started from three card sharks shooting pool has grown into an empire with annual revenue in the billions.

Did You Know
IGS's Q1 2025 revenue was NT$5.359 billion, up 28.3% year-on-year. March 2025 was the first month to surpass NT$1.8 billion. The company's market cap has already exceeded many traditional tech manufacturers.

Why Mahjong

Taiwan's mobile gaming market is brutally competitive; products with a lifespan exceeding three years can be counted on one hand. Celebrity Mahjong has been alive for over twenty years. Why?

Because mahjong satisfies a specific need: wanting to play, but unable to gather four people.

This need never goes away. On a weekday night at 10 p.m. when you want to play a few rounds, you cannot call three friends over. Before Chinese New Year when you want to practice so you are not humiliated by Grandma on the second day, you need a table that can open any time. Celebrity Mahjong fills that gap — it is not competing with other games, it is competing with the eternal problem of "can't gather enough players."¹⁵

And the uniqueness of Taiwan 16-tile mahjong makes this market almost impossible for outsiders to enter. Japanese mahjong games use 13 tiles with different rules. Chinese mahjong apps use national standard or regional rules that Taiwanese find uncomfortable. To make a mahjong game Taiwanese will actually use, you must understand 16-tile rules, understand the point system, understand flower tiles, and understand "every table has different house rules."

IGS's three founders were card sharks themselves. They were not making a mahjong game — they were moving the tile table they had played at for decades onto a screen.

The Taiwanese That Grew from the Tile Table

Taiwan's mahjong has permeated this island far beyond the tile table itself.

"Fang qiang" (放槍, "firing the gun") at the table means discarding a tile that lets someone else win — you owe the payment. In everyday life, "being fired at" has entirely left the mahjong context and become a synonym for "being stood up" or "being screwed over by someone." A friend who agrees to dinner and cancels last-minute — "fired at." A colleague who promises to help and doesn't follow through — also "fired at."

A Taiwanese person who has never played mahjong still says "bei fang qiang" (被放槍), because the metaphor is so precise: that feeling of "someone else's decision, but you bear the consequences" — decades of human dynamics at the tile table compressed into two characters. What mahjong teaches Taiwanese is far more than how to count points.

Every Table Is a Constitution

Taiwan mahjong has never had an official rulebook. Its rules are scattered across tens of millions of tile tables, each with its own version.

How are consecutive banker wins scored? Some tables add two points per win, others add one. How many points does "last-tile draw" score? Some say one, some say two, some say it depends on whether it is a self-draw or a discard win. After a kong, how many replacement tiles do you keep? Some say one tile per kong, some say one stack of two, some say keep drawing until no tiles remain.¹⁶ Does the winner take from all three other players when the third-player discard causes a win? Many northern Taiwan tables do; many southern Taiwan tables do not.

These differences have never been unified because nobody has the authority to unify them. Each tile table's rules are the consensus of the four people at that table, and the consensus source is "this is how my dad taught me."

This sounds chaotic — but the chaos itself is culture. Taiwan 16-tile mahjong is a family ritual. What is transmitted at the tile table includes rules, but also Grandpa's temper, Grandma's playing style, Uncle's expression when he deals the wrong tile, and that particular intimacy and tension that only appears at Chinese New Year.

Celebrity Mahjong did not replace that table. It did something else: it let those who had not yet earned the right to sit at the table practice the fundamentals in front of a screen first. So that when Chinese New Year comes and Grandma asks if you want to play, you can finally sit down — not peek through the door crack.

Somewhere in 2026, at Chinese New Year, in someone's living room, a young person in their twenties sits at the tile table. Grandma watches how they draw their tile, then asks: "Where did you learn?"

They do not answer.
