Mahjong Tiles Explained — All 144 Tiles, Their Suits and Their Meanings

What every tile in a mahjong set actually is: 108 suited tiles, 16 winds, 12 dragons, 8 flowers and seasons, plus the 8 jokers that turn it into the 152-tile American set.

A standard mahjong set has 144 tiles made from 42 different faces. That mismatch is the first thing that confuses newcomers: most faces appear four times, but eight of them appear exactly once. Once you understand which is which, the whole game — and every mahjong solitaire board — suddenly makes sense.

The three suits: 108 tiles

Each suit runs from 1 to 9 and each rank exists four times, so 3 suits × 9 ranks × 4 copies = 108 tiles. That is three quarters of the set.

• Characters (万 / wàn) — called Craks in American mah jongg. The rank is written as a Chinese numeral with the character for "ten thousand" above it.
• Bamboo (条 / tiáo) — called Bams. Traditionally drawn as sticks of bamboo; the 1 is a bird (a peacock or sparrow) on most sets rather than a single stick.
• Dots or Circles (筒 / tǒng) — called Dots. These began as copper coins with a square hole, which is why the 1 is a large circle and the higher ranks are rings of smaller circles.

The suits are equal in number and equal in value. Nothing in the tile set makes one suit stronger than another — any ranking between them is a rule invented by a particular variant, not a property of the tiles.

The honour tiles: 28 tiles

Honours are the tiles that cannot form a sequence. They come in two families.

Winds — 4 faces × 4 copies = 16 tiles. East, South, West and North. In Chinese mahjong the wind matching your seat is worth something; in mahjong solitaire it is just a face like any other; in American mah jongg winds appear constantly on the card because they are easy to collect in groups.

Dragons — 3 faces × 4 copies = 12 tiles. Red (中, "centre"), Green (發, "prosperity") and White (白, "blank"). White is a blank tile on many sets, which is why American players call it Soap. Red and Green are the two most recognisable tiles in any set.

The bonus tiles: 8 tiles, one of each

Here is the part that trips people up. Flowers and seasons are not four-of-a-kind. There are 4 flowers and 4 seasons, and each exists exactly once in the set — 8 tiles, 8 unique faces.

• Flowers are usually plum, orchid, bamboo and chrysanthemum.
• Seasons are spring, summer, autumn and winter.

They are numbered and paired with each other by tradition: flower 1 belongs to season 1, and so on. But mechanically they behave differently from everything else. Any flower matches any flower, and any season matches any season. A flower will never match a season.

That is why they are special, and it has real consequences:

• In mahjong solitaire they are the most flexible tiles on the board — a free move you can hold in reserve.
• In American mah jongg they appear on the card as single tiles in specific positions, and a joker can never replace a flower. A one-tile group is a one-tile group.
• In Chinese variants they are usually set aside immediately for bonus points, which is why experienced players expose them the moment they are drawn.

How our solitaire board builds its 144 tiles

The mahjong solitaire board on this site reproduces the real set exactly, with one small adaptation you can verify by playing:

• All 34 ordinary faces (27 suited + 4 winds + 3 dragons) appear four times each = 136 tiles.
• The bonus group is two flower faces and two season faces, each appearing twice = 8 tiles.

The reason for the adaptation is fairness. In a physical set there is only one of each flower, so a turtle layout using the true 8 bonus tiles would contain four flowers that can only pair with each other and four seasons in the same position — a very thin pool. Doubling two of each keeps the bonus group at 8 tiles while giving every bonus tile a partner. Everything else matches a real set tile for tile.

The American set: 152 tiles

American mah jongg adds 8 jokers to the standard 144, for a 152-tile set. Jokers are genuinely wild, but they are not unlimited, and the restriction is the single most important rule in the game:

• A joker may fill a group of three or more — a pung, kong or quint.
• A joker may not be used in a pair.
• A joker may not replace a flower.

So if a hand on the card calls for a pair of 5 Dots, two jokers will not do. You need the real tiles. Every American Mah Jongg game on this site follows that rule exactly.

Why tile counts matter when you play

Two practical uses:

Reading a solitaire board. Knowing that each ordinary face exists four times tells you when you are in danger. If you have already removed three of a face and the fourth is buried under two layers, you know that pair will not come back until the stack above it is gone — so plan around it now rather than later.

Counting in a four-player game. With four copies of every ordinary face visible between the wall, the discards and three opponents' melds, you can often work out whether a tile you need is still live. If all four are accounted for, stop waiting for it.
