White Dragon

One of three types of dragon tiles. 

The White Dragon tile is typically engraved with a rectangle outlining the edge of the tile. 

The White Dragon is also called “Soap” in American Mah Jongg due to the original White Dragon tile being a blank tile and therefore looking like a bar of soap. 

The White Dragon can be used to represent a zero (“0”) in some hands. 

The White Dragon is associated with the Dot suit unless used as a zero. When the White Dragon is used as a zero, the White Dragon is suitless

An American Mah Jongg set of tiles must contain 4 White Dragon tiles.
