I read a quote the other day that mentioned that kids in ancient Egypt played “knucklebones” with sheep toe bones. The game of knucklebones led to dice games for boys, and jacks, usually played with a wooden ball, for girls.
It’s been on my mind since. Because as a kid I often wondered about the shape of the jacks. Why 4 rounded points and two sharp ones? See here: (https://www.museumofplay.org/app/uploads/2021/08/jacks_0.png)
Were these jacks designed for the game or were they already used for something else and were just co-opted into the game of jacks?
When were they first made and by whom (in the above mentioned form)?
