"I commenced an examination of a game called 'tit-tat-to'": Charles Babbage and the "First" Computer Game

This paper examines Charles Babbage's tic-tac-toe automaton using original notes and sketches taken from Babbage's notebooks. While Babbage's work with games and computers has been mentioned previously by other authors, this is the first attempt to study that work in detail. The paper explains the origins of the automaton, imagines how it would have operated had it been built, describes how it might have functioned, and Babbage's inspirations for building it. The paper concludes with an analysis of Babbage's place in the history of videogames.
