I don't have Linux so I can't test. Here are some tips I could google:https://forums.linuxmint.com/viewtopic.php?t=449156https://www.reddit.com/r/linux_gaming/comments/17n1aq5/unity_games_will_not_open...
Installed FreeSolitaire so I could run it in Wine (Windows Emulator for Linux) and still could not run the program. There's no .exe file in the downloaded zip.
Make sure you download FreeSolitaire_Win64._2025.06.20.zip and unzip.
The executable is FreeSolitaire.exe
