## BACKGROUND
|
||||
|
||||
9mm is legit a great game.
|
||||
|
||||
One time i wrote an essay about the social contract implicit to nine mens morris:
|
||||
https://write.tildeverse.org/dozens/nine-mens-morris-cultural-meanings-and-social-contracts
|
||||
|
||||
Kind of obsessed with this variation about COWS
|
||||
https://en.wikipedia.org/wiki/Morabaraba
|
||||
|
||||
also look at these round cows
