A standard Mahjong set contains 144 tiles divided into five categories: three numbered suits, wind tiles, dragon tiles, flower tiles, and season tiles. Understanding what each tile is — and how it is used — is the first step to understanding Mahjong strategy.
This guide covers every tile in a standard Mahjong set.
The Three Suits (108 tiles)
The three suits form the backbone of most winning hands. Each suit contains tiles numbered 1 through 9, with four identical copies of each tile — 36 tiles per suit, 108 suit tiles in total.
Bamboo (竹 / Bam)
Bamboo tiles are one of the most visually distinctive in the set. In traditional Chinese Mahjong sets, they depict bundles of bamboo sticks — the 1-Bamboo tile typically shows a bird (sometimes a peacock or sparrow) instead of a single stick.
- 1-Bamboo through 9-Bamboo — 4 copies of each = 36 tiles
- Often abbreviated Bam in English
- 1-Bam and 9-Bam are terminals
In Hong Kong Mahjong, an all-Bamboo hand (pure flush) is one of the high-scoring hand types.
Characters (萬 / Wan)
Characters tiles display the Chinese numeral for each number (一萬 through 九萬), meaning “ten thousand” — a reference to their historical use in money-themed games.
- 1-Characters through 9-Characters — 4 copies of each = 36 tiles
- Also called Wan (from 萬) or Crak in some communities
- 1-Wan and 9-Wan are terminals
Circles (筒 / Dots)
Circles tiles display circular shapes — one circle for the 1 tile, up to nine arranged in a grid for the 9 tile.
- 1-Circles through 9-Circles — 4 copies of each = 36 tiles
- Also called Dots, Tongs, or Balls
- 1-Circles and 9-Circles are terminals
Terminals vs Simples
Within each suit:
Terminals — the 1 and 9 tiles. There are 6 terminal types × 4 copies = 24 terminal tiles. Terminals can only appear at the edge of a sequence (e.g., 1-2-3 or 7-8-9) and cannot be used in the middle. This makes them less flexible, which is why they appear in discard pools early in most games.
Simples — tiles numbered 2 through 8. There are 21 simple types × 4 copies = 84 simple tiles. Simples can appear anywhere in a sequence, making them the most versatile tiles in the game. A 5 of any suit can start a 3-4-5, a 4-5-6, or a 5-6-7 sequence — three different sequences — making it the most flexible tile in the set.
Wind Tiles (16 tiles)
Wind tiles are honour tiles — they have no numerical value and cannot form sequences. They can only be used in pairs or pungs (three of a kind).
| Tile | Symbol | Copies |
|---|---|---|
| East Wind | 東 | 4 |
| South Wind | 南 | 4 |
| West Wind | 西 | 4 |
| North Wind | 北 | 4 |
Total: 16 wind tiles
How Wind Tiles Work
Wind tiles have two levels of value:
Seat wind: Each player is assigned a wind based on their seat position at the table. East deals first; the other seats rotate South, West, North counter-clockwise. A pung of your own seat wind earns bonus points.
Round wind: The current round is also named for a wind (the first round is typically the East round). A pung of the current round wind also earns bonus points.
If your seat wind matches the current round wind (as it does for the East dealer in the East round), a pung of that wind earns double the usual bonus.
Wind tiles that are neither your seat wind nor the current round wind are called guest winds — they earn no bonus and are often discarded early.
Dragon Tiles (12 tiles)
Like wind tiles, dragon tiles are honour tiles — they can only be used in pairs or pungs, never sequences.
| Tile | Name | Symbol | Copies |
|---|---|---|---|
| Red Dragon | Chun (中) | 中 (Middle) | 4 |
| Green Dragon | Fa (發) | 發 (Prosperity) | 4 |
| White Dragon | Baak (白) | 白 (White) / blank | 4 |
Total: 12 dragon tiles
How Dragon Tiles Work
A pung of any dragon tile earns bonus points in Hong Kong Mahjong, regardless of the round or your seat. Dragons are strategically valuable because they are always worth points and cannot form sequences (reducing the competition for them).
The White Dragon tile is unique — it is often depicted as a completely blank tile or with a thin border only. In older or antique sets, the White Dragon may have the character 白 inscribed; in many modern sets it is plain white.
The “Three Great Scholars” (三元牌)
A hand containing pungs of all three dragons is called the “Three Great Scholars” (三元牌, Saam Yuen) and is one of the highest-scoring hands in Hong Kong Mahjong — typically classified as a limit hand.
Flower Tiles (4 tiles)
The four Flower tiles correspond to four flowering plants in Chinese culture:
- Plum Blossom (梅)
- Orchid (蘭)
- Chrysanthemum (菊)
- Bamboo (竹) — distinct from the Bamboo suit tiles
Each Flower tile is also numbered 1 through 4, corresponding to the four seat winds (1 = East, 2 = South, 3 = West, 4 = North).
Season Tiles (4 tiles)
The four Season tiles represent the four seasons:
- Spring (春)
- Summer (夏)
- Autumn (秋)
- Winter (冬)
Season tiles are also numbered 1 through 4, with the same seat correspondence.
How Bonus Tiles Work in Play
When you draw a Flower or Season tile:
- Place it face-up in front of you
- Draw a replacement tile from the end of the wall (the “dead wall” or “kong box”)
- That replacement is your actual tile for the turn
Bonus tiles do not count toward your hand structure but add points to your score when you win. In Hong Kong Mahjong:
- Each bonus tile adds 1 point
- Drawing your own-seat bonus tile (the Flower or Season matching your seat number) earns extra points
- Drawing all four Flowers or all four Seasons (only possible by luck) can be a limit hand in some rule sets
How Many of Each Tile Exist?
This is critical for strategy — knowing whether a tile is “live” (still available to draw) or “dead” (all four copies visible) changes what you should build toward.
| Category | Tile Types | Copies Each | Total |
|---|---|---|---|
| Bamboo suit | 9 | 4 | 36 |
| Characters suit | 9 | 4 | 36 |
| Circles suit | 9 | 4 | 36 |
| Wind tiles | 4 | 4 | 16 |
| Dragon tiles | 3 | 4 | 12 |
| Flower tiles | 4 | 1 | 4 |
| Season tiles | 4 | 1 | 4 |
| Total | 144 |
Every numbered suit tile exists in exactly four copies. When you see one copy in your hand and two in the discard pool, there is only one left available anywhere. When you have two in your hand, the other two are somewhere else — in the wall, or in other players’ hands.
Tile Identification Tips
Mahjong sets vary dramatically in their artwork. Traditional Chinese sets use Chinese characters; Western and novelty sets often substitute numbers or abstract designs. If you are learning to read a set:
- Bamboo tiles: Look for stick bundles or bamboo representations. The 1-Bamboo often has a bird instead of a stick.
- Character tiles: Look for the 萬 (wan) character on every tile in the suit.
- Circle tiles: Look for circular patterns. The arrangement of dots changes with each number, similar to dice faces.
- Winds: The four Chinese characters 東南西北 appear on wind tiles (East, South, West, North).
- Dragons: 中 (Red), 發 (Green), and a blank or 白 (White).
