Hong Kong vs Taiwanese Mahjong

Both games use the same 144 tiles. Both have the same basic goal: build a winning hand before your opponents do. But sit down at a Hong Kong table after learning Taiwanese rules or vice versa, and you will notice the differences immediately. This guide explains what those differences are, how the two scoring systems work, and what to watch out for when you switch between them.

What Should You Play?

The short answer, before we get into details:

The Setup: 13 Tiles vs 16 Tiles

The first thing you notice when sitting down to Taiwanese mahjong is the hand size. Hong Kong players hold 13 tiles, drawing to 14 when they win. Taiwanese players hold 16 tiles, drawing to 17. Those extra three tiles change everything: 1) how long it takes to build a hand, 2) how many patterns you can aim for simultaneously, and 3) how much longer each round takes.

Feature	🀄 Hong Kong	🀄 Taiwanese
Starting hand	13 tiles	16 tiles
Winning hand	14 tiles	17 tiles
Winning Logic	Exponential (Doubling)	Additive (Fixed Value)
Scoring unit	Faan	Tai
Minimum to win	3 faan (typical)	1 tai (typical)
Winning Ceiling	Capped (e.g. 8 or 10 Faan)	Generally none
Self-draw payout	All 3 opponents pay	All 3 opponents pay
Discard win payout	Split among losers	Full payment by discarder
Bao (accountability) rule	No	Yes. Discarder of key tile pays all
Flower tiles	Adds a bonus Faan effect)	1 tai each.
Game pace	Fast and aggressive	Slower and defensive
Best For	Players who like rapid, high-scoring rounds	Players who enjoy high-stakes risk management

The Scoring Systems: Faan vs Tai

The way you calculate your win is the heart of the game.

Hong Kong New Style: The Faan System

In Hong Kong New Style mahjong, every winning hand earns a number of faan based on which patterns it contains. Most games set a minimum of 3 faan to win and so a hand with fewer than 3 faan simply cannot declare victory. Faan converts to points on a specific scale (not pure doubling), and the limit kicks in at 10+ faan. Payouts also depend on how you win: on a discard, the discarder pays double while the other two players each pay single. On a self-draw, all three opponents pay double.

Taiwanese: The Tai System

Taiwanese mahjong uses an additive system called Tai, which function similarly to Faan but with a much lower minimum to win. Most games require just 1 tai, which means you can win with a basic hand as long as you drew at least one flower tile. This lower floor makes winning feel more accessible but it doesn’t mean the game is easier.

Each pattern you complete adds a fixed value to your total which does not translate to exponential growth like in the HK system. Instead of trying to hit a doubling cap, you are trying to maximize your total count, point by point. This encourages a slower, more deliberate construction of your hand.

The Danger Factor: The Penalty

The philosophy of losing is where these two games diverge completely.

In Hong Kong Mahjong: When you discard a winning tile, you are penalized, but the burden is shared. All three other players pay the winner, but the person who discarded the winning tile pays more than others. It is a sting, but it is manageable.

In Taiwanese Mahjong: If you discard the tile that completes a winning hand, you are the only one who pays. You pay for the entire table. This creates an atmosphere of immense tension. Every time you discard a tile, you are essentially asking: “Am I about to pay for everyone?” In addition, there is the Bao Rule in Taiwanese Mahjong that is the cornerstone of high-stakes risk management. Not all tables play it, so decide before you begin play.

The Bao Rule: Taiwanese Mahjong’s Defining Feature

Think of the Bao rule as a “you feed them, you pay them” mechanism. It is designed to prevent players from carelessly discarding dangerous tiles when it is obvious that an opponent is collecting a specific, high-value set.

The Bao rule is typically triggered when a player discards the specific tile that completes a set for an opponent who has already exposed two sets of the same category. The most common scenarios involve throwing the final dragon tile to help complete Small Three Dragons or Big Three Dragon hands; or the 4th wind tile to help make the Big Four Winds hand. If that happens, the player who triggered the Bao rule will be the one paying for the entire table, IRRESPECTIVE of who threw the winning tile. Interesting twist, right?

Pattern Comparison: Side by Side

The table below shows a few common patterns and how they score in Hong Kong mahjong (faan) and Taiwanese mahjong (tai). Because the full comparison is quite long, the complete reference table is available on a separate page.

The Core Strategic Difference

In Hong Kong mahjong, the faan system’s exponential payouts push you to chase high-value hands. The minimum threshold of 3 faan means you’re always asking: do I have enough to win, or should I keep building? A 7-faan Full Flush pays sixteen times more than a 3-faan baseline hand, so the incentive to wait for something spectacular is real. The primary tension is between winning now at minimum value versus holding out for a big hand.

In Taiwanese mahjong, the calculation is more layered. Yes, you’re building your hand but the bao rule means you’re also watching every opponent’s open melds and tracking exactly which tiles remain dangerous to discard. With 16 tiles, you often have two viable hand directions at once, which adds a constant decision about which path to commit to. The scoring system rewards set relationships ie. whether your pungs are sequential, whether your sequences match across suits, in ways HK doesn’t recognize at all. Flowers each score individually, so luck of the draw plays a bigger role. And because Taiwanese scoring varies by group, sitting down at a new table means agreeing on a scoring sheet first. The game rewards players who know their group’s specific system deeply.

Put simply: HK is a game of ambition. Taiwanese is a game of awareness.

The Real Hurdle in Switching Mahjong Styles

At first glance, the biggest difference between Hong Kong and Taiwanese mahjong seems to be hand size: Taiwanese uses a 16-tile hand, while Hong Kong builds toward a 13-tile structure. In practice, though, that adjustment is minor. After a round or two, most players instinctively remember they’re holding extra tiles.

The real challenge? Pattern recognition.

Hong Kong Mahjong rewards speed and efficiency: players aim to hit the minimum faan threshold quickly and close the hand. Taiwanese mahjong, by contrast, constantly pushes you to evaluate multiple scoring paths. A hand can evolve in many directions depending on how sets relate, ie. what players at some tables call “sister,” “brother,” “uncle,” or “neighbor” sheungs and pungs.

For Hong Kong players switching over, this means retraining your instincts: swap laser-focus on finishing fast for scanning tiles for pattern relationships and higher-value structures. That shift, not the extra tiles, is what initially ties most players’ brains in knots.

The reverse transition has its pitfalls too. Taiwanese players moving to Hong Kong Mahjong may over-analyze patterns when the smarter play is to complete the hand quickly and claim discards aggressively.

Bottom line: tile count is easy to adapt to. Learning to see the patterns? That’s the real hurdle.
