Simultaneous Call for a Misnamed Discard (Article ID 94)
Abstract: A tile is discarded and misnamed, and two players call for mah jongg. One player calls the misnamed tile while the other player notices that the actual tile discarded is their mah jongg tile, and they call that tile rather than the misnamed tile. The player who wants the actual tile discarded and not the misnamed tile gets the tile for mah jongg, not the player who incorrectly named it. This is an example of how important it is for all players to look and listen when tiles are discarded. This ruling is not found in Mah Jongg Made Easy.
Question from a player: A tile was thrown and misnamed. Two players call for mah jongg. One player calls for the misnamed tile. The other player notices that the actual tile was thrown is their mah jongg tile and they call that tile. They do not call the misnamed tile. Who gets the mah jongg?
Answer from the NMJL: “The player who wants the actual tile that was thrown gets mah jongg, not the player who called the incorrectly named tile. Players need to look and listen when tiles are discarded.”
