Aug 29, 2017 at 15:22 | comment | added | Joel David Hamkins | Will, doesn't your example in the comments still refute the claim that "every red-blue hackenbush game is a surreal number"? Perhaps it would be good to include a discussion of this in your answer. | |

Aug 29, 2017 at 0:55 | comment | added | Timothy Chow | In The Book of Numbers, Conway and Guy explicitly say, "Hackenbush chains can be infinite! Indeed, we allow the height of our Hackenbush chains to be any of Cantor's ordinal numbers." As an example they show (among other things) a picture of $\sqrt\omega$, whose order type is $\omega^2$. | |
