This is a brief introduction to game design by Dr. Lewis Pulsipher (see Wikipedia), designer of several published games (e.g. Britannia), retired teacher (computer networking, later game design and game production), and author of the 2012 book "Game Design: How to Create Video and Tabletop Games, Start to Finish" (McFarland). A much longer and more comprehensive course ("Learning Game Design") is also available on Udemy.
