Machine to Play Game of Nim (1940) [pdf]

At the 1940 New York World's Fair Westinghouse displayed a machine, the Nimatron, that played Nim. From May 11, 1940, to October 27, 1940, only a few people were able to beat the machine in that six-week period; if they did, they were presented with a coin that said Nim Champ. It was also one of the first-ever electronic computerized games. https://en.wikipedia.org/w/index.php?title=Nim&oldid=1056951...

In the basement of my parents' house is a plastic "Dr. Nim" game that I played with as a kid. It was slightly frustrating that it was able to beat me with just plastic (as a kid).

I understand it now and the how it works. https://www.turingtumble.com is a neat modern version of it (well, that and a lot more). https://community.turingtumble.com/t/dr-nim-on-turing-tumble...
