Dear all, I doubt if any copyright laws are involved. Many moons ago when John Conway was developing his theory of partizan games he wanted a variant of Nim which had different move sets for the two players, and hit on the idea of chopping branches whose edges had two different colors from trees and other graphs, and wanted a name suggesting this. We thought that Lizzie Borden's Nim was a bit too gruesome, and I suggested Hackenbush from the Groucho Marx character. I don't think this was published until Winning Ways, where it's the first game we consider. R. On Fri, 19 Jun 2015, Eugene Salamin via math-fun wrote:
I had been wondering if the copyright was held by the movie studio that produced the Marx Brothers movie "A Day at the Races", in which Groucho plays Dr. Hugo Z. Hackenbush, a horse doctor who becomes chief of the medical staff at a financially troubled resort.

I don't know. It was someone who claimed to have a copyright on Hackenbush and was parking on the domain name hackenbush.com. Rather than deal with whomever it was, we just dropped the 'c' in the name. It looks like hackenbush.com still for sale, but the landing page is different.

Out of curiosity, who owns the copyright on "Hackenbush" ?

Does anyone know of a browser applet or smartphone app that lets a human play Red-Blue Hackenbush against a computer?
One nice way to convince people that a certain Hackenbush position H has value 1/2 would to give them a chance to play the game consisting of m copies of H plus n copies of a game with value -1, for various values of m and n, sometimes playing Red and sometimes playing Blue.
