Microsoft Solitaire, one of the most iconic games included with Windows, was originally developed to teach users how to use a mouse.
The game first appeared in Windows 3.0 back in 1990, and its simple drag-and-drop mechanics were designed to help users become comfortable with clicking, dragging, and dropping using a graphical user interface.
This fun way of learning contributed significantly to the popularization of the mouse as an essential input device.
