KBackgammon is KDE backgammon client. SHOCK!!!
It did not get as much love as other kde games for the KDE 4.0 release but we decided to keep for reasons that are not important now.
What is important is that i created 3 Junior Jobs for people that want to start with KDE 4 development and don't know where to.
If you want to have a look at them see:
Bug 149275: Enable antialias in KBackgammon
Bug 149276: Convert config dialogs to .ui files
Bug 149277: Remove engineSet usage
All three should be "fairly" straightforward even for a newcomer.
So get your brain ready and start coding.
