Mahjong Divination  

Mahjong is more than just a game, it is also an ancient Chinese method of divination.  Similar to Tarot, Mahjong tiles make use of esoteric symbolism.  The process of shuffling the tiles is like how you would randomize dominoes.  Traditionally the querent turns the tiles face down, mixes them around, and selects how many tiles are necessary for the chosen method of reading. 

Alternatively you can use a method of 3 Bones in which tiles may repeat. In this method the tiles are reshuffled between draws. If the tiles do repeat in the reading, this indicates a faster or more potent outcome.
