I hope that when you get to "H", you'll try Hnefatafl, one of my favorite ancient games.
There are dozens of different historical board sizes and rulesets, but the Copenhagen rules seem to be the most evenly balanced and absorbing.
It's listed on cyningstan(dot)com, and there are Android apps.
@Rmond I don't have a physical copy, but I've played a version of it.
Astonishingly, it doesn't look like anyone has produced an axolotl hnefatafl board.
