MAHJONG 101 · GLOSSARY

Mahjong Terms, Plainly Explained

A running glossary for every stage — point a newcomer here instead of re-explaining "soap" for the hundredth time.

Basic Intermediate Advanced

Bam

BASIC

Short for Bamboo, one of the three numbered suits (1–9). Nothing to do with actual bamboo — no plants were harmed making this tile set.

Blank

BASIC

An extra tile some sets throw in with no printed rule attached to it. Mahjong's equivalent of a junk drawer key.

Breaking a Hand

ADVANCED

Deliberately abandoning your own hand to block everyone else's instead. The mahjong version of "if I can't have it, no one can" — except it's a completely respected strategy, not a personality flaw.

Call

BASIC

Claiming someone else's discard, out of turn, because it completes a set you need. The tile equivalent of yelling "shotgun."

Charleston

BASIC

The mandatory round of passing 3 tiles at a time before real play starts. Named after the 1920s dance — nobody's fully sure why, but it's stuck for a century, so we're not going to be the ones to question it now.

Concealed

INTERMEDIATE

A hand built entirely in your own rack, with no exposed (called) sets shown to the table. Harder to build, usually worth more — mahjong's version of "no pain, no points."

Crak

BASIC

Short for Character, the second numbered suit. Yes, it's spelled that way on purpose — mahjong has never once cared about your spellcheck.

Dead Hand

ADVANCED

A hand that mathematically cannot be completed anymore — usually because a tile you needed is gone from circulation. Realizing this two turns too late is a rite of passage.

There's no formal five stages of grief for this, but there probably should be.

Defense

ADVANCED

Playing to keep opponents from completing their hands, even at the cost of your own. Not a fallback for players who "gave up" — genuinely half the game once you're playing at a serious level.

Discard

BASIC

The tile you let go of at the end of your turn, said out loud for the table to hear. Your rack's weekly cleanout, minus the guilt about the cardigan you never wear.

Dot

BASIC

Short for Circle, the third numbered suit. Somehow the tile that trips up the most beginners, despite being the one that's just... dots.

Dragon

BASIC

An honor tile in Red, Green, or White. No fire-breathing involved, though a well-timed Dragon call can feel just as dramatic.

Exposed

BASIC

A set of tiles shown face-up on your rack for the whole table to see, usually because you called it. The tile version of posting your relationship status publicly.

Flower

BASIC

A special bonus-style tile used in specific hands on the card. Pretty, mostly harmless, occasionally the exact tile you needed three turns ago.

Going Out

INTERMEDIATE

Completing your 14-tile hand and declaring Mahjong. The moment everyone else at the table simultaneously groans and asks to see your rack.

Joker

BASIC

A wild tile that can stand in for almost anything. The ultimate yes-man of your rack — agrees to be whatever you need, right up until a Singles & Pairs hand tells it no.

Kong

INTERMEDIATE

Four matching tiles. One louder than a Pung, and it knows it.

Loaded Hand

ADVANCED

Table slang for a hand leaning heavily on jokers to hold together. Structurally sound, emotionally a little bit of a house of cards.

Mahjong

BASIC

What you call out the instant your hand matches a line on the card exactly. Two syllables that end the entire round on the spot — use responsibly.

Pung

BASIC

Three matching tiles. If two's company and three's a crowd, a Pung is the crowd you actually wanted to show up.

Quint

INTERMEDIATE

Five matching tiles — only possible with jokers filling in, since there are just 4 of each real tile. Basically a Kong that got ambitious.

Rack

BASIC

The little ledge your tiles sit on so the whole table isn't just guessing your hand. Underrated piece of equipment, chronically taken for granted.

Reading the Table

ADVANCED

Picking up on hesitation, pace, and body language, not just the literal tiles being played. Part strategy, part low-stakes detective work.

ROLLOR

INTERMEDIATE

The memory trick for Charleston passing order — Right, Over, Left, Left, Over, Right. Sounds like a dance step because, frankly, it kind of is one.

Singles & Pairs

INTERMEDIATE

A section of the card built from lone tiles and pairs only — no exposed sets, no jokers allowed at all. The purist's corner of the card, and it plays like it.

Soap

INTERMEDIATE

The nickname for the White Dragon, because the blank white tile apparently reminded someone, decades ago, of a bar of soap. The name never got a rinse.

Swap

INTERMEDIATE

Trading your Joker for the real tile it's standing in for, under specific card rules. A polite eviction notice for a tile that's overstayed its welcome.

Tempo

ADVANCED

How quickly you're actually advancing your hand versus just reacting to everyone else's. Chess players call it the same thing; mahjong players just argue about it over snacks instead.

Wall

BASIC

The stack of tiles built at the start of the game that everyone draws from. Not the kind you hit — though by turn nine, you might feel like you have.

Wind

BASIC

An honor tile — North, East, South, or West. East gets the extra attention every round, mostly because East also got the extra tile.
