Bam
BASICShort 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
BASICAn extra tile some sets throw in with no printed rule attached to it. Mahjong's equivalent of a junk drawer key.
Breaking a Hand
ADVANCEDDeliberately 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
BASICClaiming someone else's discard, out of turn, because it completes a set you need. The tile equivalent of yelling "shotgun."
Charleston
BASICThe 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
INTERMEDIATEA 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
BASICShort for Character, the second numbered suit. Yes, it's spelled that way on purpose — mahjong has never once cared about your spellcheck.
Dead Hand
ADVANCEDA 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
ADVANCEDPlaying 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
BASICThe 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
BASICShort for Circle, the third numbered suit. Somehow the tile that trips up the most beginners, despite being the one that's just... dots.
Dragon
BASICAn honor tile in Red, Green, or White. No fire-breathing involved, though a well-timed Dragon call can feel just as dramatic.
Exposed
BASICA 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
BASICA 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
INTERMEDIATECompleting your 14-tile hand and declaring Mahjong. The moment everyone else at the table simultaneously groans and asks to see your rack.
Joker
BASICA 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
INTERMEDIATEFour matching tiles. One louder than a Pung, and it knows it.
Loaded Hand
ADVANCEDTable slang for a hand leaning heavily on jokers to hold together. Structurally sound, emotionally a little bit of a house of cards.
Mahjong
BASICWhat 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
BASICThree matching tiles. If two's company and three's a crowd, a Pung is the crowd you actually wanted to show up.
Quint
INTERMEDIATEFive matching tiles — only possible with jokers filling in, since there are just 4 of each real tile. Basically a Kong that got ambitious.
Rack
BASICThe 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
ADVANCEDPicking up on hesitation, pace, and body language, not just the literal tiles being played. Part strategy, part low-stakes detective work.
ROLLOR
INTERMEDIATEThe 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
INTERMEDIATEA 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
INTERMEDIATEThe 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
INTERMEDIATETrading 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
ADVANCEDHow 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
BASICThe 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
BASICAn honor tile — North, East, South, or West. East gets the extra attention every round, mostly because East also got the extra tile.
