Win32s

Win32s is an installable add-on for Windows 3.1x, which enables 16-bit Windows to run some 32-bit executables. While it includes portions of Win32 API, they're very minimalistic and insufficient for most 32-bit applications to run properly.

It also includes the famous game called Freecell, which was meant to demonstrate a 32-bit app running on 16-bit Windows.
