Owen Maitzen's animated hour-long introduction to Hackenbush, a simple combinatorial game, and how its strategy leads to surreal numbers and the roots of the number system.
HN recommends it as an accessible, well-visualized entry point to Hackenbush, surreal numbers and their link to Nim.

All numbers are fictitious :) Though, I think "games" built on surreal numbers are akin to these. [LINK] An accessible intro: [VIDEO]

Nim is, in fact, a proper subset of Hackenbush, a game extensively studied by Conway. I found the following video extremely useful and well-visualized: [VIDEO]
