SkiFree is a single-player skiing computer game created by Chris Pirih and released with Microsoft Entertainment Pack 3 for Windows and DOS in October 1991. The player controls a skier on a mountain slope, avoiding obstacles while racing against time or performing stunts for points, depending on the game mode. SkiFree was well-received upon release, with critics focusing on its simplicity and visuals. The game was ported to Macintosh and, years later, to Game Boy Color and iOS. Pirih also released a free, updated 32-bit Windows version after rediscovering his original source code. SkiFree remains popular among the gaming community and is often remembered for its Abominable Snow Monster, which pursues the player after they finish a full run.
