Mac Gaming: Mahjong Solitarus 1.3

So if you're into hardcore Mahjong,
with four players, gambling in the sweaty heat outside your local Chinese restaurant, this won't interest you that much. On the other hand, if you like puzzles, then you'll probably enjoy Mahjong Solitarus ($17 USD).
If you're not familiar with this Mahjong variant, it's a stacked tile game, where you choose matching tiles and remove them, trying to move on until there are no tiles left. Mahjong Solitarus brings the added cool option that allows you to design your own tile layout, rather than being stuck forever with the limited layouts that come with the game.  And you can even share your tile layouts over the web with other players. Fun.
