Arranging a Declared Mah Jongg (Article ID 8)
Abstract: Once a player has declared mah jongg, it’s not only permissible but standard practice to display one’s hand in the order as shown on the card. A player should reorder their tiles according to the hand on the card once they have mah jongg. By doing so, it helps other players identify the winning hand.
Question from a player: I called mah jongg and displayed my hand with jokers incorrectly. Instead of pung, pung, kong, kong, I displayed pung kong, pung, kong. Since I had the correct 14 tiles, can I rearrange them?
Answer from the NMJL: “A player is not required to place exposures in the order in which they are shown on the card; however, when Mah Jongg is declared, tiles should be re-arranged to show the correct order.”
