[math-fun] Hackenbush applet?
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.

yes, we (ie greg whitehead and i, acting as counterwavegames.com) made one. it runs only on ipad we dropped the 'c' from the name for copyright reasons, but here you go http://www.hakenbush.com thane On Thu, Jun 18, 2015 at 11:48 AM, James Propp <jamespropp@gmail.com> wrote:

I'm currently planning to write my August 17 blog post on values of Hackenbush games (including ones with infinite or infinitesimal value), in conjunction with the MOVES meeting taking place Aug. 2-4 (dedicated to Berlekamp, Conway, and Guy). In keeping with my goal of having something that readers of my blog can DO ("virtual manipulatives", if you like), I'd like to give them a way to play (finite!) Hackenbush against a perfect adversary. Ideally it should be available to everyone, not just those who own iPads. If no such thing currently exists, would any of you be willing to create it?

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.

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. -- Gene From: Thane Plambeck <tplambeck@gmail.com> To: Eugene Salamin <gene_salamin@yahoo.com>; math-fun <math-fun@mailman.xmission.com> Sent: Thursday, June 18, 2015 7:36 PM Subject: Re: [math-fun] Hackenbush applet?

I would be very, very surprised if anyone at all had a defensible IP claim to the game Hackenbush, or to the association between the name and the game, and even more surprised if anyone attempted to make such a case. The website name is at most a trademark, and probably not even that. I am not a lawyer, however. On Thu, Jun 18, 2015 at 11:00 PM, Eugene Salamin via math-fun < math-fun@mailman.xmission.com> wrote:

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:

Richard, about Hackenbush: "I don't think this was published until Winning Ways, where it's the first game we consider." Winning Ways was 1982. Martin Gardner already excerpted it ten years earlier (Scientific American, January 1972): "Conway calls the new game Hackenbush, but it has also been called Graph and Chopper, Lizzie Borden’s Nim and other names. The following description is taken from a chapter by Conway in 'Hackenbush, Welter, and Prune', a discussion of several nimlike games that will appear in an exciting book-in-progress by Elwyn R. Berlekamp, Conway and Richard K. Guy."
