The invention discloses a mahjong
machine and a tile supplying method thereof. Four sets of tile collection and transportation systems are independently arranged respectively and not arranged in a staggered mode, in a tile supplying component, a tile storage groove is bent in a large-angle arc shape, the storage number of mahjong tiles in the tile storage groove is increased, the height and manufacturing cost of the main unit of the mahjong
machine are greatly lowered, and the use experience and the comfort are better. A cover plate which can be opened upward is arranged, therefore, in the rising process of a tile lifting supporting plate, the mahjong tiles on the edges of the tile lifting supporting plate can lift the cover plate, after the tile lifting supporting plate is parallel to and level with a desktop plate of the mahjong
machine, the cover plate is returned, and accordingly the situation is avoided that a larger gap is formed between the tile lifting supporting plate and the desktop plate of the mahjong machine or marginal mahjong tiles on the edges bump against the desktop plate of the mahjong machine. Accordingly, a grading tile supplying mode can be adopted, a player can start to play mahjong tiles by only setting upright six and half sets or thirteen tiles of supplying tiles for the first time, the process of manual tile distribution and arraying is omitted, the player operates the mahjong tiles more easily and conveniently, and the entertainment experience is better.
