Fall Mahjong Harvest Moon - Version 1.0 A full moon is rising with Harvest Moon Mahjong. The closest full moon to the Autumnal Equinox, we'd say this mahjong solitaire layout accurately represents the awesomeness of the Fall season! Just like the classic turtle mahjong game, just match tiles to remove them from the mahjong board. Click on any tiles that cannot be selected at this time and they will gray out, showing you which mahjong tiles can be selected at that time. This can be a difficult mahjong board, so be sure to use the undo and hint buttons if necessary! Keep beating it until you get three mahjong stars!
