A Mah Jongg Game set consists of tiles - of which there are 34 different types.
These are the four Winds, East, South, West and North, the three Dragons, Green, Red and White, the Bamboo tiles, numbered one to nine, the Circles tiles, numbered one to nine, and the Wan tiles, again numbered one to nine. For each of the 34 different tile types there are four identical pieces provided in a Mah Jongg set. The total number of playing tiles in Game is therefore 136 tiles.
However in a set there are also eight special tiles that are used solely for the purpose of scoring bonus points, the Flower and Season tiles, we therefore have a total of 144 tiles in a Mah Jongg set as illustrated in the symbolic square of Mah Jongg.
