This is the single-player version of the classic Chinese game, played according to Japanese rules (Tenwa). You start out with 14 tiles, and have to first discard one of them. When choosing the first tile to discard, your goal is to create a ready hand (a hand of 13 tiles which is one tile away from a winning hand). Then you must find the right tile in the wall to complete a winning hand. In standard Mahjong, discarded tiles can be used to complete a hand. In Solo Mahjong Pro, this is not the case. Discarded tiles do not participate in the game in any way.
