American Mahjong Tiles Explained

Here’s the whole set in six lines:

• An American mahjong set has 152 tiles. 144 game tiles plus 8 jokers.
• Three suits: Dots, Bams, and Craks. 36 of each. Numbered 1 through 9, four of each number.
• Honor tiles: 16 Winds (North, East, West, South, 4 of each) and 12 Dragons (red, green, white/soap, 4 of each).
• 8 Flowers. All flowers count as identical for hand-building, no matter what they show.
• 8 Jokers. Wild tiles. They can sub into any group of three or more matching tiles on the card.
• The white dragon is also the "0" in any hand that calls for zeros. Same physical tile, two jobs.

The first time you pop open a mahjong set, you see chaos. A bird. A red squiggle. Some Chinese characters you can't read. A blank tile that you're pretty sure is broken. Eight tiles with flowers on them. Eight tiles with a giant red word that says JOKER. Your friend tells you that you're going to play a game with these. You count the tiles. There are way more than you expected.

That's the moment most new players quietly decide that mahjong is going to be hard. It isn't. The set has 152 tiles, and once you know what every one of them is and why it's in the box, the overwhelm collapses into a system. This is that system. Every tile family, what it looks like, how many of each, what they do, and why the white dragon is also a zero.

The 152 tiles: the whole set at a glance

A standard American mahjong set has exactly 152 tiles: 108 suit tiles across three suits, 16 winds, 12 dragons, 8 flowers, and 8 jokers.

Here's the full inventory:

• 36 Dots (circles): 1 through 9, 4 of each
• 36 Bams (bamboo): 1 through 9, 4 of each. The 1 Bam is a bird.
• 36 Craks (characters): 1 through 9, 4 of each
• 16 Winds: North, East, West, South. 4 of each.
• 12 Dragons: Red, Green, and White (the white is also called Soap). 4 of each.
• 8 Flowers
• 8 Jokers

That's 152. American mahjong uses all of them. Other styles (Chinese, Japanese, Hong Kong) play with the same 144 base game tiles but skip the Jokers entirely. The Jokers are what make the American game what it is.

The three suits: Dots, Bams, and Craks

The three suits in American mahjong are Dots, Bams, and Craks, each numbered 1 through 9 with four copies of every tile, giving you 108 suit tiles in total.

The bulk of a mahjong set, 108 of the 152 tiles, is the three suits. Each suit is numbered 1 through 9, with 4 of each number. They're the working tiles. Most hands on the NMJL card are built from these.

The three suits are interchangeable for hand-building purposes. When the card calls for "any 2 suits" or "any 3 suits," you're picking how many distinct suits the hand uses, not which colors they are.

Dots (also called Circles)

Dots are the easiest suit to read because the number on the tile matches the number of circles you see. A 3 Dot has three circles. A 7 Dot has seven. The circles are arranged in standard patterns, so once you've seen a 5 Dot you'll always recognize it.

36 Dots in the set. 1 through 9, 4 of each. Sometimes the 1 Dot has a more ornate artistic flourish, but it still just means "one." If you can't remember what suit you're looking at, count the circles. That's the Dots.

Bams (also called Bamboo or Sticks)

Bams are the suit with the green or red bamboo sticks. 2 through 9 Bams look exactly like what you'd expect: a 4 Bam has four sticks, a 9 Bam has nine. Count the sticks.

The 1 Bam is different. The 1 Bam is a bird. Sometimes a sparrow, sometimes a peacock, sometimes something that looks like a rooster depending on the manufacturer. It's always a bird, and the bird IS the 1 Bam. There is no "stick" version of it.

This is the single most common point of confusion for new players. You hold up a tile with a bird on it and ask "what is this?" It's a 1 Bam. It plays as a 1 in the Bam suit, just like a 5 Bam plays as a 5. The bird is decoration on a numerical tile.

36 Bams in the set. Four of those are birds, because there are four 1 Bams.

Craks (also called Characters or Wans)

Craks have a number on top and a Chinese character on the bottom. The character is the word "wan" (which means 10,000), and the number on top tells you which Crak it is. A 4 Crak has the digit 4 above the character.

You don't need to read Chinese to play. Read the number on top, ignore the character. 36 Craks in the set, 1 through 9, 4 of each. New players sometimes mistake Craks for Winds because both have characters on them. The shortcut: Craks always have a number on top. Winds don't.

Winds: North, East, West, South

Winds are honor tiles. Four of them: North (N), East (E), West (W), South (S). 4 of each, so 16 Winds in the set. Usually labeled in English with a single letter, though older or imported sets use the Chinese characters for the directions. If a term in this guide is unfamiliar, the mahjong glossary has every definition in one place.

The 2026 NMJL card has a whole section called Winds-Dragons that uses Wind tiles as part of hand combinations. Winds also show up in pungs and kongs across other sections. They play just like a suit tile, except they don't have numerical neighbors. A North is a North. You only group it with other Norths.

Note: every player is also assigned a wind position for the round (East, South, West, North), which is a separate concept from the Wind tile itself. The position matters for seat rotation and who deals. The tile is just a tile you might build a hand around.

Dragons: Red, Green, and White (Soap)

There are 12 dragon tiles in a standard set: four each of Red, Green, and White (also called Soap). Dragons are not wild tiles. The only wild tiles in American mahjong are the 8 jokers.

Dragons are the other set of honor tiles. There are three Dragons: Red, Green, and White. Four of each, so 12 dragons in the set.

• Red Dragon: A bold red character (the Chinese word "chun"). Sometimes called the chun. Pairs with the Crak suit on the NMJL card.
• Green Dragon: A green character (the Chinese word "fa"). Sometimes called the fa. Pairs with the Bam suit on the NMJL card.
• White Dragon: A tile with a blue or black frame around an empty middle, or sometimes a tile that looks completely blank. Often called the Soap because it looks like a bar of soap. Pairs with the Dot suit on the NMJL card. The White Dragon is also a zero (more on this below).

The suit pairings matter. When a hand on the card has a Red Dragon next to Crak tiles, the Red Dragon "belongs to" the Crak family for that hand. Green Dragons pair with Bams. White Dragons pair with Dots. The colors aren't decoration; they're a system. This is one of the easiest pieces of strategy to learn and one of the easiest to forget.

New players sometimes panic when they see what looks like a blank tile and think they have a defective set. The blank is the White Dragon. It's supposed to be that way. If your set has truly extra blank tiles (no frame, completely empty), those are usually replacement tiles meant for a Joker that goes missing.

Why the White Dragon is also a "zero"

This is the single most confusing thing about the dragons, and it trips up almost everyone the first time they see a "0" on the NMJL card.

Several hands on the card (especially the 2026 section and others that use specific digits) call for tiles that read as 0. There is no physical "0" tile in the set. The White Dragon doubles as the 0.

So if a hand calls for FF 2026 2026, you'd use two Flowers and then 2 + 0 + 2 + 6 + 2 + 0 + 2 + 6, with the 0s played as White Dragons. Same physical tile, doing a different job for that hand.

You only treat the White Dragon as a 0 when the hand calls for it. In a hand that calls for a pung of White Dragons, the White is being used as a Dragon. Same tile, context-dependent role. One more thing: when the White Dragon is played as a 0, it's suit-neutral. It does not have to match the suit of the number tiles next to it. So a hand like 2026 can have its 0 played as a White Dragon regardless of whether the 2s and 6s are Dots, Bams, or Craks. The first time you see it on the card you'll squint. Then you can't believe you ever found it confusing.

Flowers: 8 tiles, all identical for hand-building

Flowers are a set of 8 tiles that almost always feature flower or season imagery. The artwork varies wildly from set to set: cherry blossoms, lotuses, plum branches, four seasons in different colors, sometimes Roman numerals.

The rule that matters more than the artwork: for hand-building purposes, all 8 Flowers count as identical. A pair of Flowers can be any two Flower tiles in the set. A quad of Flowers is any four of them. If a hand calls for FFFF, you need four Flowers. Any four will do.

Some other styles of mahjong (Chinese, Hong Kong) distinguish Flowers and Seasons individually. American mahjong does not. All 8 Flowers are interchangeable. Flowers are also the only non-Joker tile that almost never appears in a discard pile, because most hands need them.

Jokers: the 8 wild tiles that make American mahjong what it is

Each set contains 8 jokers, and they are the only wild tiles in the game. A joker can stand in for any tile inside a group of three or more identical tiles (a pung, kong, or quint), but jokers are never legal in a single or a pair.

There are 8 Jokers in the set, usually with a bold red word JOKER or an artistic joker face. They are wild. They can stand in for any tile in a group of three or more matching tiles in your hand.

Two things to know that matter more than anything else:

1. Jokers can only sub into groups of 3 or more. A Joker cannot stand in for a single tile in a pair. If a hand calls for a pair of 5 Dots, both tiles must be actual 5 Dots. A Joker cannot complete a pair.
2. Jokers cannot be passed during the Charleston. Not in any pass. Not in the Courtesy. Ever. We cover this in detail in the full Charleston guide.

Beyond that, a Joker can substitute for any tile in any pung (3 of a kind), kong (4 of a kind), quint (5 of a kind), or sextet (6 of a kind) on the card. A Joker held in your hand is one of the most valuable tiles you can have, because it gives you flexibility right up until the moment you call mahjong.

Jokers can also be "redeemed" once they've been used in an exposure on the table. If another player (or you) has a Joker exposed in a pung, kong, or other group, and you have the actual matching tile, you can swap your real tile for that Joker on your turn. The redeemed Joker comes back into your hand. You can redeem from another player's rack or from your own exposed group. Jokers cannot be redeemed from the discard pile, only from exposures. This is one of the highest-leverage moves in the game when it's available.

The full mechanics of redemption, exposure rules, and what counts as a legal Joker substitution live in the full joker rules guide.

Caring for your tiles

A set of mahjong tiles is a thing you'll use for years. Treat it well.

Cleaning

Wipe tiles with a soft, dry cloth after a long session. If they get sticky from snack hands, a barely-damp cloth and a quick dry will handle it. Avoid soaking the tiles or using cleaning sprays directly on them. Many sets are made of Bakelite, urea, or vintage materials that don't love moisture.

Storage

Most sets come with a case or a wooden box. Keep the tiles in their case when you're not playing. It keeps the set together, protects the tiles from temperature swings, and means you never sit down for a game and realize you're missing a Joker. A closet shelf is fine. The top of a sunny windowsill is not. Heat warps tiles and fades the colors over time, especially the red on Craks and the green on Dragons.

The rack

Most American mahjong players use a tile rack to hold their 13 tiles upright during play. Racks usually come as a set of four. Many racks also include a pusher (the long flat tool you use to scoot tiles around when you're stacking the wall at the start of each hand). If you're investing in your first set, get racks and pushers in the same finish. They fit better and look better on the table.

You don't need a fancy set to start playing well. You need a complete set: 152 tiles in good condition, racks for everyone, and the current NMJL card. The card refreshes every April. The tiles last for decades.

The whole set in one sentence

An American mahjong set has 152 tiles: three suits of 36 (Dots, Bams, Craks, all numbered 1 through 9 with four of each), 16 Winds, 12 Dragons (with the White Dragon also serving as a 0), 8 Flowers (all interchangeable), and 8 Jokers (wild, but only in groups of 3 or more).

Save this. Read it before your next game. The hands on the card stop being intimidating the moment you know what every tile in your rack actually is.

What to do once you know the tiles

Knowing the tiles is step one. Step two is learning how they come together into hands. The 2026 NMJL card has 55 hands across 9 sections, and the way to feel confident reading it isn't to memorize all 55. It's to know what every tile in your rack can become.

Your strategy at the table shouldn't be "guess what hand to go for." It should be "read the card and decide based on what's in your hand." That shift, from guessing to reading, is the difference between a player who knows the rules and a player who actually plays well.

If you've made it this far and you're realizing you want to actually drill this with a real set in front of you, the Build Your Table series is where new players start. It's the structured path from "I just opened a tile set" to "I'm playing in my first game next week." If you want to see the tools and accessories I actually use at my own table, those live in Lara's Favorites.

Two natural next reads: how to read the NMJL card, since every hand you build with these tiles comes off that sheet, and how American mahjong scoring works, which covers what a winning hand actually pays.

For the rest of the rules, start here if you're brand new, or use the glossary to look up any term in this post that didn't quite land. If you want to drill alongside other players who are learning the same things, the Confidence Club is where I do this work with members every week.

See you at the table.
