Mahjong scoring varies by variant—from Riichi's han/fu system to Hong Kong's faan-based doubling. Learn how each system works and how to count points.
Mahjong scoring is the most variant-specific aspect of the game, and no single system applies everywhere. Whether you play American Mahjong with its annually updated NMJL card, Japanese Riichi with its han/fu lookup tables, or Hong Kong style with its exponential faan-based payments, understanding how points are calculated transforms you from a casual player into a strategic one. This guide breaks down each major scoring system so you can count points with confidence.
Mahjong scoring differs between variants because each regional tradition developed its own way to reward hand difficulty and rarity. The core principle is universal: more difficult hands earn higher scores. But the math, the terminology, and the payment structures diverge significantly from one style to the next.
When mahjong spread from China to Japan, Southeast Asia, and eventually the West during the early 20th century, each region adapted the scoring to fit local preferences. Some systems use additive points, where you tally individual elements. Others use exponential doubling, where a single extra scoring element can multiply your payout dramatically. The result is that a player fluent in Hong Kong scoring will find American scoring almost unrecognizable, and vice versa.

Here is a high-level comparison of the five major scoring systems:
| Feature | American (NMJL) | Riichi (Japanese) | Hong Kong Old Style | Taiwanese | MCR (Competition) |
|---|---|---|---|---|---|
| Scoring Unit | Points (cents) | Han + Fu → Points | Faan | Tai | Fan (points) |
| Payment Structure | Fixed per hand | Lookup table | Exponential (2^faan) | Exponential (2^tai) | Additive |
| Minimum to Win | Match a card hand | 1 han (some rules) | 3 faan (common) | Varies by house | 8 fan minimum |
| Number of Patterns | ~50 per year | ~40 yaku | ~30 scoring elements | ~30 scoring elements | 81 fan patterns |
| Self-Draw Bonus | All 3 pay winner | Tsumo: all pay | Self-draw: all pay | Self-draw: all pay | 8 bonus points |
| Complexity | Low (card-based) | High (systematic) | Medium | Medium | High |
Understanding which system you are playing is the first step. Each of the sections below walks through a specific variant's scoring in detail. If you are just starting out and want structured guidance, you can find mahjong lessons near you to learn the scoring system used in your area.
American Mahjong scoring is card-based: every winning hand must match one of the specific patterns printed on the current year's National Mah Jongg League (NMJL) card. Each hand on the card has a fixed point value — typically 25 or 30 cents in casual play — and the winner collects that amount from each other player.
The NMJL releases a new card every April, which means the valid hands change annually. Players cannot simply memorize patterns once and rely on them forever. The card organizes hands into categories such as "2468" (even-numbered hands), "Winds–Dragons," "Singles and Pairs," and others. Each category contains several specific tile combinations, and every combination lists a point value.
Payment in American Mahjong follows straightforward rules. If you win by self-drawing your final tile (picking it from the wall yourself), all three opponents pay you the full value of the hand. If you win by claiming another player's discard, only the discarder pays double while the other two players each pay the single value. This creates a meaningful incentive to win by self-draw — a principle shared across nearly every mah jongg variant.
[CALLOUT:tip]In American Mahjong, always check the current NMJL card before sitting down to play. Hands from last year's card are not valid, and attempting to declare mahjong with an outdated pattern results in a dead hand.[/CALLOUT]
Because American Mahjong uses 152 tiles (including 8 jokers), jokers can substitute for tiles in groups of three or more. However, jokers cannot be used in pairs or singles. Hands that require no jokers — sometimes marked as "C" (concealed) on the card — tend to have higher point values because they are harder to complete. The scoring system is intentionally accessible: you look at the card, match the hand, and collect the listed amount. There is no complex multiplication or lookup table involved.
Riichi (Japanese) mahjong uses the han/fu system, a two-variable calculation that determines final point values through a structured lookup table. Han represent the difficulty multipliers earned from specific winning patterns called yaku, while fu represent minipoints awarded for the composition of individual melds and the way you win.
Every winning hand in Riichi mahjong must contain at least one yaku — a recognized scoring pattern. Common yaku include riichi (declaring a ready hand with a 1,000-point bet), tanyao (all simples, using only tiles numbered 2 through 8), and pinfu (a fully sequential concealed hand with a valueless pair). Each yaku is worth a specific number of han, typically 1 to 6 for standard patterns, with rare yakuman hands worth a flat 32,000 or 48,000 points.
Han are additive. If your hand qualifies for riichi (1 han), tanyao (1 han), and ippatsu (1 han for winning within one turn of declaring riichi), your total is 3 han. Additional han come from dora — bonus tiles indicated by an indicator tile on the dead wall. Each dora tile in your hand adds 1 han but does not count as a yaku by itself.
Fu are minipoints awarded for specific hand elements. A base of 30 fu applies to most winning hands (20 fu for a pinfu tsumo). Closed triplets of terminal or honor tiles add 16 fu each. Open triplets of simple tiles add only 2 fu. Quads (kan) add even more. After totaling, fu are rounded up to the nearest 10.
Once you have both han and fu, you cross-reference them on a scoring table. For example, 3 han and 40 fu yields 5,200 points for a non-dealer ron (winning off a discard). At 5 han or above, fu become irrelevant — the hand is scored at a flat rate called mangan (8,000 for non-dealer), haneman (12,000), baiman (16,000), sanbaiman (24,000), or yakuman (32,000).
Self-drawn wins (tsumo) split payment among all three opponents, with the dealer paying double. Discard wins (ron) charge the full amount to the single discarder. This split payment system makes tsumo strategically valuable even when the total points are the same.
Riichi scoring is complex but entirely systematic. Once you memorize the common yaku and understand the fu calculation, the lookup table does the rest. Many players use scoring reference cards or apps until the values become second nature.
Hong Kong Old Style mahjong uses the faan system, where each scoring element adds faan (doubles) and the final payment increases exponentially based on the total. A hand worth 3 faan pays significantly less than a hand worth 5 faan, because each additional faan roughly doubles the payout.
The base payment is typically a small agreed-upon amount — for example, $1 or 1 chip. The formula in many groups is payment = base × 2^(faan), though some tables cap the maximum faan at 10 or 13. Common scoring elements include:
Many Hong Kong tables enforce a minimum of 3 faan to declare a winning hand. This rule prevents players from winning with trivially easy hands and keeps the game competitive. The 3-faan minimum is not universal, however — some social groups play with a 1-faan or even 0-faan minimum, so always confirm house rules before starting.
[CALLOUT:warning]Hong Kong mahjong house rules vary widely. Always confirm the faan minimum, maximum cap, and payment rates before the first hand. Disagreements over scoring mid-game are common when players come from different groups.[/CALLOUT]
The exponential nature of faan scoring creates dramatic swings. A 3-faan hand at a $1 base pays $8. A 7-faan hand at the same base pays $128. This steep curve rewards players who pursue ambitious hands rather than racing to complete easy ones. It also means a single high-scoring hand can reverse an entire session's results.
Payment in Hong Kong mahjong follows a similar self-draw versus discard split. When you win by self-draw, all three opponents pay. When you win off a discard, only the discarder pays — often at a higher rate to compensate.
Taiwanese mahjong uses the tai system, which functions similarly to Hong Kong's faan system with exponential payment scaling. Each tai doubles the base payment, and the total tai count determines how much the winner collects from opponents.
Taiwanese mahjong has several distinctive features that affect scoring. The game uses 16 tiles per player's starting hand (instead of 13 in most other variants), and flower tiles play a prominent scoring role. Each flower tile matching your seat wind earns 1 tai. Collecting all four flowers of one set (spring/summer/autumn/winter or plum/orchid/bamboo/chrysanthemum) awards a substantial bonus.
Common tai-earning patterns in Taiwanese mahjong include:
The base payment is set before the game begins. With exponential scaling, a hand worth 5 tai at a base of $10 pays $320 (10 × 2^5). Most tables set a tai cap — commonly 5 or 8 tai — to prevent runaway payouts. Without a cap, a lucky hand with stacked bonuses could result in enormous payments.
One unique aspect of Taiwanese scoring is the "responsibility" payment rule in certain situations. If a player discards a tile that allows an opponent to complete a particularly valuable hand — such as a hand involving a big three dragons or four winds pattern — that discarder bears additional financial responsibility. This rule encourages defensive play and careful discarding, especially in the late stages of a round.
Taiwanese mahjong's scoring rewards aggressive play and flower collection. Players who draw many flower tiles gain a scoring advantage before they even complete their hand, which adds an element of luck that some players enjoy and others find frustrating.
Mahjong Competition Rules (MCR) scoring uses an additive point system with 81 recognized fan patterns and a minimum of 8 points to declare a winning hand. This system was standardized for international tournament play and is governed by the World Mahjong Organization.
MCR is the most codified scoring system in mahjong. Each of the 81 fan patterns has a fixed point value, ranging from 1 point (such as Short Straight or One Voided Suit) to 88 points (such as Thirteen Orphans or Big Four Winds). Points from multiple patterns are added together — there is no exponential doubling. This additive structure makes MCR scoring more linear and predictable than Hong Kong or Taiwanese systems.
Key MCR scoring tiers include:
| Points | Example Patterns |
|---|---|
| 88 | Big Four Winds, Thirteen Orphans, Nine Gates |
| 64 | All Terminals, Little Four Winds, Four Concealed Pungs |
| 48 | Quadruple Chow, Four Pure Shifted Pungs |
| 32 | Four Shifted Chows, Three Kongs |
| 24 | Seven Pairs, Full Flush, Pure Triple Chow |
| 16 | Pure Straight, Three Suited Terminal Chows |
| 12 | Big Three Winds, Knitted Straight |
| 8 | Mixed Straight, Reversible Tiles, Mixed Triple Chow |
| 6 | All Pungs, Half Flush |
| 4 | Outside Hand, Fully Concealed, Two Concealed Kongs |
| 2 | Dragon Pung, All Chows, Double Chow, Tile Hog |
| 1 | Short Straight, One Voided Suit, Self-Drawn, No Honors |
The 8-point minimum to win is a defining feature. You cannot declare mahjong unless your hand's total fan value reaches at least 8. This minimum forces players to build meaningful hands and prevents quick, low-value wins from dominating tournament play. Reaching exactly 8 points often requires combining several small patterns — for example, All Chows (2) + Concealed Hand (2) + Self-Drawn (1) + One Voided Suit (1) + No Honors (1) + Short Straight (1) = 8 points.
[CALLOUT:info]MCR's "exclusion principle" prevents double-counting: if a higher-value pattern already includes a lower-value pattern by definition, you cannot score both. For example, scoring Full Flush (24 points) means you cannot also count Half Flush (6 points) for the same hand.[/CALLOUT]
MCR also awards 8 bonus points for a self-drawn win, making tsumo especially valuable. In tournament settings, players track cumulative scores across multiple rounds, and the player with the highest total at the end of the event wins. This long-form scoring rewards consistency over single-hand luck.
Despite their differences, all major mahjong variants share several core scoring principles that reward skillful play and hand-building discipline. Understanding these shared ideas helps you adapt quickly when switching between styles.
1. Hand difficulty determines value. In every variant, hands that are harder to complete score higher. A hand using only one suit is worth more than a mixed hand. A fully concealed hand beats an open one. All-terminal hands outrank all-simple hands. This principle is the foundation of mahjong strategy: you constantly weigh the risk of pursuing a difficult, high-scoring hand against the safety of completing an easy, low-scoring one.
2. Self-drawn wins score higher than discard wins. Across American, Riichi, Hong Kong, Taiwanese, and MCR mahjong, completing your hand by drawing from the wall — rather than claiming an opponent's discard — earns bonus points or spreads the payment burden. In Riichi, tsumo adds 1 han. In Hong Kong, self-draw adds 1 faan. In MCR, it adds 1 fan plus the 8-point base bonus. This universal bonus exists because self-drawn wins give opponents no chance to play defensively.
3. Concealed hands outrank open hands. Keeping your hand closed (not calling tiles from others' discards) is harder because you rely entirely on your own draws. Every scoring system rewards this difficulty. In Riichi, many yaku are only valid for closed hands. In MCR, Fully Concealed is worth 4 fan.
4. Payment flows from losers to winners. Mahjong is a zero-sum game within each hand. The winner gains exactly what the losers pay. In discard wins, the discarder typically bears the primary cost. In self-drawn wins, all opponents share the payment. Some variants add dealer bonuses — in Riichi, the dealer (East) receives 50% more points for winning.
5. Defensive play has scoring implications. Discarding a tile that lets an opponent win ("dealing in" or "playing into") carries a penalty in most variants. In Riichi, the full ron payment comes from the discarder. In some Taiwanese rules, the discarder pays extra for enabling certain high-value hands. Smart defensive play — reading opponents' discards and avoiding dangerous tiles — directly protects your score.
These principles mean that even if you learn only one variant's specific scoring rules, the strategic instincts you develop transfer to every other style of play.
The fastest way to learn mahjong scoring is to play regularly with experienced players who explain their hands at the end of each round. Repetition builds pattern recognition far more effectively than memorization alone.
Here are practical strategies for each variant:
Playing online is another excellent way to practice scoring, because digital platforms calculate points automatically. You see the breakdown after each hand and learn which combinations produce which scores. Over time, you start recognizing scoring opportunities during play rather than only after.
If you want personalized guidance, consider working with an instructor who specializes in your preferred variant. You can find mahjong lessons near you to accelerate your learning. Joining a local group is equally valuable — experienced club members are often happy to walk newcomers through scoring. You can join a mahjong club to find regular playing partners in your area.
