Sorry, no installation package for Diablo.
But if you really want to try this, then in theory this should work:

From PC:
1. Download the latest source files archive from:
http://repository.maemo.org/extras-t..._0.72-1.tar.gz
2. Extract the files to some directory (might be that you first have to extract the .gz which gives you .tar and you have to extract that again, depends on your archive manager)
3. Find the following directory from the extracted files: src -> opt -> outlawsolitaire
4. Copy the whole outlawsolitaire directory to your device.

From device:
1. Open terminal
2. Go to the outlawsolitaire directory
3. Run:
If all goes well, the game should start.
Please note that you have to have python and python-pygame packages installed.
