Editing Hex (board game) (section)

===Nash's claim===
The game was rediscovered in 1948 or 1949 by the mathematician [[John Forbes Nash Jr.|John Nash]] at [[Princeton University]].<ref name="Gardner1">{{cite book|title=The Scientific American Book of Mathematical Puzzles & Diversions|url=https://archive.org/details/scientificameric02gard|url-access=registration|last= Gardner|first= M.|year= 1959|publisher= Simon and Schuster|location=N.Y., N.Y.|isbn= 0-226-28254-6|pages=[https://archive.org/details/scientificameric02gard/page/73 73–83]}}</ref><ref>{{cite news|last1=Nasar|first1=Sylvia|title=The Lost Years of a Nobel Laureate|url=https://www.nytimes.com/books/98/06/14/reviews/nasar-nash.html|access-date=23 August 2017|work=The New York Times|date=13 November 1994}}</ref> According to [[Martin Gardner]], who featured Hex in his July 1957 [[Mathematical Games column]], Nash's fellow players called the game either Nash or John, with the latter name referring to the fact that the game could be played on hexagonal bathroom tiles.<ref name="Gardner1"/> Nash insisted that he discovered the game independently of Hein, but there is some doubt about this, as it is known that there were Danish people, including [[Aage Bohr]], who played Hex at Princeton in the 1940s, so that Nash may have subconsciously picked up the idea. Hein wrote to Gardner in 1957 expressing doubt that Nash discovered Hex independently. Gardner was unable to independently verify or refute Nash's claim.<ref>{{cite book |last1=Hayward |first1=Ryan B. |last2=Toft |first2=Bjarne |title=Hex, inside and out : the full story |year=2019 |publisher=CRC Press |location=Boca Raton, Florida |isbn=978-0367144258 |pages=127–138}}</ref> Gardner privately wrote to Hein: "I discussed it with the editor, and we decided that the charitable thing to do was to give Nash the benefit of the doubt. ... The fact that you invented the game before anyone else is undisputed. Any number of people can come along later and say that they thought of the same thing at some later date, but this means little and nobody really cares."<ref name="HexFullStory"/>{{rp|134}} In a later letter to Hein, Gardner also wrote: "Just between you and me, and off the record, I think you hit the nail on the head when you referred to a 'flash of a suggestion' which came to Mr. Nash from a Danish source, and which he later forgot about. It seems the most likely explanation."<ref name="HexFullStory"/>{{rp|136}}
