I have created the online version of the popular board game Carcasson on Facebook.
This is a real-time, multiplayer game, the server side is built in Python.
You need a Facebook account to try it.
If you are behind a corprate firewall chances are that you won’t be able to connect to the rtmp server.

Here is the link to the game: http://apps.facebook.com/carcasson/
And here is some info about the rules: http://www.facebook.com/apps/application.php?id=155395464480894&sk=info
