Frank B. Adams (December 19, 1847 – December 29, 1929), commonly known as Yank Adams, was a professional carom billiards player who specialized in finger billiards, in which a player directly manipulates the balls with his or her hands, instead of using an implement such as a cue stick, often by twisting the ball between one's thumb and middle finger. Adams, who was sometimes billed as the "Digital Billiard Wonder", has been called the "greatest of all digit billiards players", and the "champion digital billiardist of the World." George F. Slosson, a top billiards player of Adams' era, named him the "greatest exhibition player who ever lived." Adams' exhibitions drew audiences of 1,000 or more, leaving standing room only, even in small venues.
