American Mahjong Terms: A Beginner-Friendly Glossary
Learn the essential American Mahjong terms, from Charleston and jokers to pungs, kongs, exposures, dead hands, walls, winds, dragons, and soap.
American Mahjong has its own table language. At first it can sound like everyone else got a vocabulary list you missed: Charleston, soap, pung, exposure, dead hand, joker exchange. Once the words click, the game gets calmer because you can finally connect what people are saying to what is happening on the rack.
This glossary explains the terms you are most likely to hear at a U.S. American Mah Jongg table, with practical notes on why each term matters. It does not reproduce the National Mah Jongg League card; use it alongside the current card for legal hands and scoring.
Core Game Terms
American Mahjong / American Mah Jongg The U.S. style of mahjong played with racks, jokers, a Charleston, and an annual card of valid winning hands. Many players spell it "mah jongg" because that is the spelling used by the National Mah Jongg League.
NMJL card The annual National Mah Jongg League card. It lists the valid hands for the year, the required tile groupings, whether a hand is exposed or concealed, and the hand's value.
Mah Jongg The winning declaration. A player calls Mah Jongg when their 14 tiles exactly match one line on the current card and all rules have been followed.
Wall The face-down tiles players draw from during the game. In American Mah Jongg, each wall is built two tiles high and 19 stacks long.
Rack The holder in front of each player. Your concealed tiles sit on the sloped part of the rack. Called exposures are placed on top.
East The dealer or first player. East starts with 14 tiles and makes the first discard after the Charleston.
Tile Terms
Bams, Craks, and Dots The three numbered suits. Each suit has numbers 1 through 9, with four copies of each tile.
Winds The honor tiles marked East, South, West, and North. Each wind has four copies.
Dragons Red Dragon, Green Dragon, and White Dragon. The White Dragon is commonly called soap.
Flowers Special tiles used in many American Mah Jongg hands. There are eight flowers in a standard American set.
Joker A wild tile used in groups of three or more, such as pungs, kongs, quints, and sextets. Jokers cannot be used in singles or pairs unless the card or table rule explicitly permits a rare exception.
Natural tile Any non-joker tile. If another player exposes a group containing a joker and you have the matching natural tile, you may be able to exchange your natural tile for that joker on your turn.
Grouping Terms
Single One tile by itself. Jokers cannot stand in for singles.
Pair Two identical tiles. Jokers cannot be used in pairs.
Pung Three identical tiles. Jokers may be used in a pung.
Kong Four identical tiles. Jokers may be used in a kong.
Quint Five identical tiles. Quints almost always require jokers because there are only four natural copies of most tiles.
Sextet Six identical tiles. Sextets require jokers and appear in some American Mah Jongg contexts.
Chow A sequence of three suited tiles, such as 3-4-5 dots. Chows are not used as standard groups in American Mah Jongg hands, but beginners may hear the term because it exists in other mahjong variants.
Play Terms
Charleston The tile-passing phase before regular play begins. Players pass three tiles right, across, and left. A second Charleston may follow, and a courtesy pass may happen at the end if players agree.
Blind pass Passing a tile received from another player without looking at it. This is used when you do not want to give up three tiles from your own hand.
Draw and discard The normal turn rhythm after the Charleston. A player draws from the wall, then discards one tile.
Call Claiming another player's discard to complete a legal exposure or to declare Mah Jongg.
Exposure Tiles placed face-up on top of the rack after calling a discard. Exposures reveal information and can make your hand easier for opponents to read.
Concealed hand A hand marked concealed on the card. You cannot expose tiles for a concealed hand during play, except that you may call the final winning tile for Mah Jongg.
Dead hand A hand that can no longer legally win because of an error, illegal exposure, wrong tile count, or impossible card match.
Strategy Tips
- Learn terms by category, not alphabetically. Tile types, group sizes, and play actions are the three buckets that matter most.
- When reading the card, translate every line into singles, pairs, pungs, kongs, quints, and suits.
- Treat every exposure as public information. If you expose early, opponents can often narrow your hand down to a few card sections.
- Respect joker limits. Most beginner mistakes come from trying to use jokers in pairs or singles.
- Ask what table rules are being used before play starts. Social tables vary on hot wall, dead-hand handling, and timing habits.
How to Use This Glossary at the Table
Do not try to memorize every term in one sitting. Start with the words that change what you are allowed to do: joker, pair, exposure, concealed, Charleston, and dead hand. Those terms affect real decisions during play.
When someone says a word you do not know, connect it to an action. "Exposure" means tiles are now public on top of the rack. "Concealed" means you cannot call along the way. "Pair" means jokers cannot help. That is the kind of vocabulary that actually improves your game.
FAQ
Is it spelled mahjong or mah jongg?
Both are common. "Mah Jongg" is common in American NMJL-style play. "Mahjong" is broader and often used online. Using both terms in content helps players find the article regardless of spelling.
What is the most important American Mahjong term for beginners?
The most important term is "card." American Mahjong is built around the annual card. You are not just collecting sets; you are building one exact listed hand.
Can I call a tile for a pair?
Usually no. You cannot call a discard to complete a pair unless that tile gives you Mah Jongg.
