Because of the structure of the game, Mahjong can also be used as an oracle. The Mahjong set contains symbolism that allows it to be used for doing readings – using several familiar tarot spreads. Using the offline method, the process of shuffling the tiles is the same as the way one would randomize dominoes. The querent turns the tiles face down, mixes them around, and selects how many tiles are necessary for the chosen layout.
Alternatively, there is 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.
