Although he developed it on his home computer for his own education and entertainment, WinSki attracted the attention of a program manager for the Microsoft Entertainment Pack (MEP) when he noticed Pirih playing it at work.[1] At that time, the first MEP had become so successful that the MEP team was designing two more.[2] In October 1991, Microsoft shipped MEPs 2 and 3 for Windows 3 and DOS, the latter pack containing Pirih's game renamed and marketed by Microsoft as SkiFree.[3][9] It was distributed on Verbatim 3.5-inch GameSampler floppy disks, bundled with packs of 10 other blank floppy disks in the early 1990s.[10]
