Trick or Treat - Halloween is here and with it our Halloween themed Mahjong game. Halloween is one of the scariest holidays, but at the same time one of the most loved and awaited by children. We've tried to make our game as spooky as it is fun, suitable for both young and old. The flower tiles, from the original Mahjong, are matched here by the treat ones. The season tiles, from the original Mahjong, are matched here by these depicting tombstones.
