Misnamed discard

A discard was called by the wrong name. What now?

Calling a tile More about calling a tile

Question 1 of up to 2

Did anyone act on the wrong name — call the tile, rack it, expose tiles for it, or declare Mah Jongg — before the mistake was corrected?

Read every possible ruling for this situation

Just rename

Just correct the name — no penalty

Standard rule
Simply correct the name. The discarder — or anyone who notices — says the tile’s real name, and play goes on with no penalty. The tile itself stays on the table: the discarder does not take it back, and does not swap in the tile they named even if they are holding it. Once correctly named, the discard is live and may be called for an exposure or for Mah Jongg like any other. If the table cannot agree on what was said, this card cannot settle that; the tile on the table is what counts.
Why
A discard is the tile, not the word; the name only exists to help players see it, so fixing the name fixes the problem.
Common house rules
Some groups let the discarder exchange the misnamed tile for the one they named. The standard keeps the thrown tile down and only corrects the name.

If your table agreed on a house rule before the game, that rule wins.

Mahjongg on misname

Mah Jongg was called on the wrong name — the hand stops

Standard rule
The hand stops right there. A player who declared Mah Jongg on the strength of the wrong name is treated as the injured party: under the standard rule the penalty falls on the player who misnamed the tile, and the other two players owe nothing. It is not recorded as a win for the claimant, and it is not scored as a normal Mah Jongg. This applies even if the misnamed tile was actually a Joker. Settle it the way your table scores penalties, then shuffle and deal the next hand.
Why
Every player depends on hearing discards called correctly, so the cost of a false name lands on the player who spoke it.
Common house rules
Some social tables simply correct the name and keep playing, with no penalty. That is a house rule; the standard ends the hand.

If your table agreed on a house rule before the game, that rule wins.

Exposure on misname

An exposure on the wrong name is the caller’s risk

Standard rule
The player who racked the tile or put up an exposure based on the wrong name now has an incorrect exposure, and another player may call that hand dead; the discarder owes no penalty. Everyone at the table is expected to look at a discard as well as listen to it. If the mistake was not noticed until the next player had already drawn and racked, the misnamed tile is simply covered — too late for anyone to call it, and nothing more to decide.
Why
Looking before you call is each player’s own responsibility, so a misheard name does not shift the cost to the discarder.
Common house rules
Some tables let the exposing player put the tiles back if the misname is caught before they discard. The standard holds the exposure once tiles are up.

If your table agreed on a house rule before the game, that rule wins.
