Mahjong Scoring — Points, Han, Fu & Scoring Systems Explained

Mahjong scoring varies dramatically across variants — from the simple fan-doubling of Hong Kong Mahjong to the mathematical precision of Riichi’s han/fu system. This guide explains how scoring works in every major variant.

Scoring Concepts Shared Across Variants

Despite the differences, most Mahjong scoring systems share these principles:

1. Pattern-based value: The specific combination of tiles in your hand determines its worth
2. Multiplier system: Scoring patterns act as multipliers on a base value
3. Winner takes payment: The winning player receives points from one or more losing players
4. Self-draw vs. discard: How you win often affects who pays and how much
5. Dealer bonus: In most variants, the dealer receives increased payouts

Chinese Classical Scoring

The System

Chinese Classical Mahjong uses a base points + fan (doubles) system:

1. Calculate base points from your hand composition
2. Count fan (番) from scoring patterns
3. Final score = base points × 2^fan

Fan Patterns

Payment Rules

The player who discarded the winning tile typically pays the full value. For a self-draw win, all three opponents share the payment. The dealer pays and receives double in most house rules.

Limit Hands

To prevent astronomical scores, Chinese Classical uses limit values. Once a hand reaches a certain fan threshold, it caps at the limit regardless of additional patterns.

Riichi Mahjong (Han/Fu) Scoring

Riichi Mahjong has the most precise scoring system. Every hand is valued using two components:

Han (翻) — The Multiplier

Han come from yaku (scoring patterns) and dora (bonus tiles):

Fu (符) — The Base

Fu are calculated from the composition of your hand:

Fu are always rounded up to the nearest 10.

The Scoring Table

Here are the most common payment values for non-dealer winning by ron:

Limit Hands

At 5+ han, scoring shifts to fixed payouts:

Tsumo Payments

When winning by self-draw (tsumo), each opponent pays a portion:

• Non-dealer tsumo: Dealer pays double, other two players pay the smaller amount
• Dealer tsumo: All three opponents pay equally

Example: Mangan tsumo by non-dealer = 2,000 from each non-dealer + 4,000 from dealer.

American Mahjong Scoring

The Card System

American Mahjong scoring is entirely different from Asian variants. The NMJL publishes an annual card listing all valid winning hands with their point values.

How It Works

1. Study the current year’s card
2. Build one of the listed hand patterns
3. If you complete the hand, you win the listed point value
4. Point values vary by hand difficulty (typically 25 to 100+ points)

Card Categories

The annual card organizes hands into categories:

Scoring and Payment

Payment is determined by the hand’s listed value and whether it was won by self-draw or discard:

• Discard win: The player who discarded pays double the hand value. The other two players each pay single value.
• Self-draw win: All three opponents pay double the hand value.

Hong Kong Mahjong Scoring

The System

Hong Kong Mahjong uses straightforward fan-based scoring with a minimum fan requirement (typically 3 fan):

Common Fan Values

Payment Calculation

Base payment × 2^fan. Common structures use a table:

Competition Mahjong (MCR) Scoring

The System

MCR uses an 81-pattern fan system with a minimum of 8 fan to win:

Selected Patterns

Scoring Calculation

In MCR, hands must total at least 8 fan from the combined patterns. The winner receives their fan total as points, plus a base of 8 points from each opponent. Patterns can stack — a hand might combine “All Chows” (5 fan) + “Concealed Hand” (2 fan) + “Self-Drawn” (1 fan) = 8 fan exactly.

Scoring Comparison Across Variants

Tips for Learning Scoring

1. Start with the basics — Don’t try to memorize every scoring table immediately. Learn the common hands and their values.
2. Use apps — Scoring calculators are available for every variant. Use them until you internalize the system.
3. Focus on han in Riichi — Fu calculation matters less at higher han values because limit hands override the fu component.
4. Know the minimums — Understand the minimum winning requirements for your variant so you don’t accidentally build an invalid hand.
5. Practice scoring hands — After each game, manually calculate your hand’s value to build the skill.
