By playing through the game, you can unlock a secret set of ancient tiles. Some of these tiles are earned through experience and some are awarded for cunning. Mahjong World doesn't just come with the regular 144 tile layouts, it has 3 different sizes to challenge you. There are small layouts for when you need that quick Mahjong fix, or huge layouts for when you have a lot of time on your hands! Gentle oriental music and sounds will sooth your soul as you match tiles.
