The 1960 Game of Life was a wholly original work created by Reuben Klamer. While the Milton Bradley 1860 Checkered Game of Life served as one historical point of inspiration, specifically the word "life" according to Reuben, it is an entirely different game than the iconic Game of Life, created by Reuben Klamer. A side by side comparison of the two games clearly illustrates this.
Additionally, artist Bill Markham was hired by Reuben Klamer to help build the prototype of The Game Of Life, a role the federal courts confirmed was that of a contracted developer working at Klamer's direction and expense. (Markham Concepts, Inc. v Hasbro, Inc., No. 19-1927 (1st Cir. 2021)
The Game of Life’s creation, authorship, and commercial history are well documented through official and reputable sources including the Smithsonian Institution, The Strong National Museum of Play, and relevant legal records.
It was Reuben Klamer’s 1960 Game of Life game that became widely recognized and went on to sell tens of millions of copies worldwide and become a worldwide part of how we play!
