KDE Games under XFCE4

I would like to know where the executable files for the various Solitaire games that come with KDE are located When I call up kde from a terminal in XFCE4, I get the icons and task bar from KDE's desktop. I then call up the relevant solitaire game. However, when I close the terminal window, the background remains KDE's and not XFCE's, so I'd like a different way to call up the games. Thanks for your help dj tuchler
