I also found a (very old-school--looks a lot like the Windows 3.11 version of Solitaire, except with actual Scopa card faces) version of Scopa for download and install that I really like, here:

I like the Nancy Drew one (especially since you don't have to listen to him gloat in the online version!) for graphics and gameplay, but it's slow on my computer--the free/installed one is, obviously, much faster.
