History
Microsoft's Solitaire (1990), which came free with Microsoft Windows, is widely considered the first hit "casual game" on a computer, with more than 400 million people having played the game as of 2007. Subsequent versions of Windows included casual games Minesweeper, FreeCell, and Spider Solitaire. The company published four Microsoft Entertainment Packs for casual gaming on office computers from 1990 to 1992.
