The number of tiles on a KMahjongg board layout can differ from the number of tiles in the standard Mahjong tile set. That means that the number of occurrences of tiles of the same type can also differ from the number stated in the table above.
Only the “open” tiles can be selected.
“Open” tile is the tile which has one of the tile's lateral sides open, meaning that no other tiles are located immediately next to it.
Only when matching, open tiles can be removed from the game board.
Matching tiles are those where the face pictograms match.
Note:
There are exceptions to this rule! In the traditional game of Mahjong each tile has a matching one except for the “Flowers” and “Seasons” tiles.
The “Flowers” tiles have no doubles in the set and can be matched directly to each other.
The “Seasons” tiles have no doubles in the set and can be matched directly to each other.
Not every KMahjongg game can be finished. Sometimes the tiles are mixed in such a way that it may not be possible to find all the matches. This problem can be avoided. Please refer to this section of the configuration dialog.
To be eligible for a place amongst the high scores the player has to complete a game instance within the shortest period of time possible.
Note:
If the player uses the “Hint” feature the record will not be considered as a high score.
