Whatajong is an open source html5 multiplayer solitaire built with nodejs and socket.io.

You can try a hosted version at fuckmahjong.com

cp default.conf.js conf.js

Edit the conf.js file with your specific configuration and you are ready to go!

Half the game work in the client, and the other half in the server. Both parts are communciated via socket.io exchanging events and state. There is a file public/js/tile.js that works in the server and the client so we can't give some instant feedback to the user.
