I guess Wikipedia is lying 🙁 It says there it was released for both Windows and DOS, which got me excited.
https://ski.ihoc.net/ this seems to be the best resource there is for Ski Free, as this website is made by the same guy who made Ski Free. They offer two versions there: the 32-bit latest version (which requires Windows 95 and up) and the original 16-bit version (which runs in Windows 3.x).
But none of these run in plain DOS, as Wikipedia is implying ;(
