Naming Your Discards, and "Down Is Down"
Every tile you throw has to be said out loud. Here is what to call each one, and what happens when you get it wrong.

American mahjong is played out loud. You don't just discard a tile — you say what it is, every single time, and the timing rules depend on you doing it.
New players discover this the hard way, usually by sliding a tile onto the table in silence and watching three people wait for something.
What to call each tile
| Tile | Say | Not |
|---|---|---|
| Suit tiles | Number first — "two bam", "seven crak", "four dot" | "bamboo two", "seven characters" |
| Winds | Just the direction — "north" | "north wind" |
| Dragons | "red", "green", "white" or "soap" | "red dragon" is fine but slower |
| Flowers | "flower" | never a number — they're interchangeable |
| Jokers | "joker" | — |
| Same as the last one | "same" | — |
Short is better. The table needs to hear it and react inside a second, and "seven crak" carries across a room in a way that "seven of characters" doesn't.
If East's very first discard of the game is a joker, it must be named as a joker. Every other discard is a courtesy backed by the timing rules; that one is explicit.
Down is down
A discard is final once you've fully named it — right or wrong — or once any part of it touches the playing area. Whichever comes first.
You cannot take it back. Not if you misspoke, not if you realise it was the wrong tile, not if nobody has claimed it yet.
When you name it wrong
You correct yourself. The tile stays on the table.
And here's the part that matters: until the tile is named correctly, it can't be claimed. The window doesn't properly open on a tile the table can't identify.
If somebody claims a misnamed tile and it turns out to be something else, that's their problem, not the discarder's. Which means: look at the tile, don't just listen. The name is a signal, not a guarantee.
Why the rule exists at all
Because of the window of opportunity. A discard becomes claimable the moment it's named or lands, and stops being claimable when the next player racks a tile. That whole mechanism needs a clear starting gun.
Silent discards break it. If nobody heard the tile, nobody can decide whether to claim, and the window closes on people who never got the chance to use it. That's why silent slides annoy experienced players — it isn't fussiness, it's that you've quietly removed their options.
Saying "same"
If you're discarding the same tile that was just discarded, "same" is a complete and correct call. It's faster, it's clear, and it's standard.
One thing to know alongside it: when two identical tiles are discarded in quick succession, only the second one can be claimed. The first is dead.
How to sound like you've done this before
- Name it as you place it, not before and not after. The word and the tile landing should be simultaneous.
- Say it at conversation volume. Not a mutter, not an announcement.
- Don't editorialise. "Two bam" — not "two bam, I really don't want to throw this". You're giving away information and slowing the table.
- Don't pause dramatically before discarding a dangerous tile. Everyone notices, and now they know.
The related habit worth building
Listen to everyone else's calls, and watch what they expose. Every named discard is a free piece of information about what that player has decided they don't need — which, several turns in, tells you a lot about what they do need.
The players who seem to have supernatural instincts about what's safe to throw are mostly just people who were listening.

Naming conventions, the down-is-down rule, the requirement to correct a misnamed tile and the placement of risk on the claimer follow the American Mah-Jongg Association's published rulebook section on playing the game.
