I learned to play jacks at a two month summer camp in the Adirondacks in NY. It was so much fun, and we played as much as we were able, although we only had specified times for ‘play time’, the rest was regimented sports. LOL. The only place were on the porches of the main cabins, which were granite. We learned to be very careful. The girls from Cuba were experts, and I’m trying to remember all the game names. I do remember around the world, onsies, twosies, etc., and jumpsies (we were horse crazy). I’m glad to have found this group.
