Mahjong Rules for Beginners

Mahjong rules are easiest to understand in two layers. First learn the shared framework: tiles, wall, draw, discard, claims, and a completed hand. Then add the rules that make your chosen variant distinct. This prevents a Hong Kong scoring rule, a riichi restriction, or an American card convention from being taught as universal.

Mahjong rules at a glance

Mahjong Rules for Beginners: Stage, Common framework, What varies

Stage	Common framework	What varies
Setup	Players shuffle tiles and build or prepare a wall	Tile count, flowers, dice procedure, and dead wall
Deal	Players receive a concealed starting hand	Exact dealing method and dealer’s extra tile
Turn	Draw or claim, then discard	Call timing, replacement tiles, and penalties
Hand	Build groups, a pair, or a recognized special shape	Legal patterns and open/closed restrictions
Win	Declare and reveal the hand	Minimum fan, points, yaku, or annual-card line
Score	Settle the value and rotate or retain the dealer	Every major variant uses a different system

These are navigation points, not a substitute for a complete rulebook.

Equipment and tile families

A common Chinese set has 144 tiles: 108 suited tiles, 28 honors, and eight flowers and seasons. Games that omit bonus tiles use 136. American sets add jokers and racks; riichi sets commonly omit flowers and may include red fives.

The three numbered suits run from one to nine. Winds and dragons are honors. A numbered sequence must stay within one suit; 8-9-1 is not a sequence, and honors cannot form sequences. See how many tiles are in mahjong for a complete count by variant.

Setup, deal, and turn order

Traditional tables build four walls of stacked tiles. Dice determine where the wall opens, but the counting formula is ruleset-specific. East is the initial dealer. In many four-player styles, East begins with 14 tiles while the other players hold 13, so East makes the first discard.

Play normally moves counter-clockwise. A turn starts when a player draws or legally claims a tile and ends when that player discards. Declaring a kong usually requires a replacement draw because four physical tiles are being used as one group.

Use the mahjong setup guide for the physical table and the dealing guide for a slower walkthrough.

Calls from the discard pile

Calls interrupt the normal draw. The usual vocabulary is:

• Chow/chi: a three-tile suited sequence.
• Pung/pon: three identical tiles.
• Kong/kan: four identical tiles.
• Win: the discard completes a legal winning hand.

Do not assume all players may claim every sequence. Many rule sets limit chow to the next player in turn. Pung, kong, and winning claims usually have wider reach, and simultaneous claims need a priority rule. State calls clearly and wait long enough for a higher-priority declaration.

Winning shape and scoring requirement

In many variants, a standard winning hand contains four groups and a pair. Seven Pairs and Thirteen Orphans are examples of special shapes recognized in some systems. A structurally complete hand may still be unable to win:

• MCR requires at least eight points from recognized combinations.
• Riichi requires at least one yaku; dora are bonuses, not permission to win.
• Hong Kong tables commonly set a minimum fan, but the threshold and payout chart vary.
• American mahjong requires one exact line from the current card.

This is why “Is the hand complete?” and “Is the hand legal to win?” are separate questions.

Key differences between major mahjong rules

Mahjong Rules for Beginners: Feature, Hong Kong style, MCR

Feature	Hong Kong style	MCR	Riichi	American
Main hand model	Melds plus pair	Melds plus pair and listed exceptions	Melds plus pair or listed exceptions	Exact annual-card pattern
Primary value unit	Fan	Points	Han and fu	Printed card value
Special mechanism	Table fan minimum	Eight-point minimum	Yaku, furiten, dora, riichi	Charleston, jokers, racks
Flowers	Often used	Used	Not used	Used as ordinary card-specified tiles

The variant comparison explains which guide to use next.

A fair way to teach the rules

Teach the first practice hand face up. Ignore payment and ask players to complete a basic legal shape. On the second hand, enforce calls. On the third, add the minimum scoring requirement. This sequence separates tile recognition from procedural memory.

Before the first real round, record:

1. Ruleset and edition.
2. Minimum required to win.
3. Flower and replacement procedure.
4. Claim priority and multiple-win policy.
5. Dealer continuation and game length.
6. Payout or point table.

Common rules disputes

A household may have played one convention for decades without using a published name. That tradition is valid at its own table, but it is still a house rule. Trouble starts only when an unlabelled custom is presented as the rule for every game.

Another common dispute is counting score before validating the hand. First arrange the groups and pair, confirm open or closed status, and verify the winning tile. Only then total fan, points, han and fu, or the card value.

Rules references

• The Mahjong Competition Rules PDF is a complete reference for MCR, including equipment, calls, scoring combinations, and penalties.
• The Mahjong International League recognizes several international and local systems, supporting the variant-first approach used here.
• Use MahjongWiki’s dedicated Chinese, Hong Kong, riichi, and American pages for rules that cannot be generalized safely.

Table rule: if a rule changes whether a hand may win or who pays, agree on it before the wall is built.
