You can get the following applications in the kdegames distributions.
Stable applications are relatively bug free and come in source and binary formats.

Unstable versions change daily and are only in source form, meaning you must compile them to get a working version. Remember these are unstable and might not even compile. If you have a problem with an unstable application report the problem and it will most likely be fixed in a future snapshot.
