The game uses a special set of 144 tiles somewhat similar to those used in the game of dominoes, but divided into groups in a manner similar to the colours in cards and forming several other groups - Winds, Dragons and Flowers and Seasons. There are different versions of the rules with more or less of a random element. Many countries have madjong tournaments and as a result a great many different sets of rules have been created: several Chinese types, Japanese, British, European, American and others.
