I remember playing this when I was a kid growing up in Baltimore in the early 80’s. I think we used to call it skellet(s)? I live in nowhere Pennsylvania now and no one here has ever heard of it. We used to melt wax in them also, and when it got really hot out we would scrape the soft tar off the street and put it in the cap for weight and cover it with the wax. I sucked at that damn game.
