Caravaggio and BigDave
The snobs game was called 'alley-gobs' where I was dragged up.
So I googled it and low and behold more names appear for the same game:-
Chucks, Dibs, Handles, Hondies, Jacks, Pot Checks and of course knucklebones (the use of bones from sheep). So I can fully understand anyone not quite associating the name snobs with the game.
I ran this past some work mates and the snobs was the favourite.
