Just to point out that the article on "brass ring" omitted the information that most of the rings in the dispenser were steel or iron. So simply catching a ring did not win a prize, unless the brass ring was the one being offered. Friends of mine learned to pull several rings in succession, in one pass, in case the brass was next or even two or three after the one visible. The ride operator could also swing the dispenser arm back so no rings were offered for a time, and no chance for a brass ring at all.
