Carom billiards
In three-cushion billiards, sometimes called three-cushion carom, three-cushion, three-cushions, three-rail, rails and the angle game, the object is to carom off both object balls with at least three rails being contacted before the contact of the cue ball with the second object ball. Arising sometime in the 1870s, the origin of three-cushion billiards is not entirely known. It is undisputed that the Internal Revenue Collector of the Port of St. Louis, Wayman C. McCreery, made the game popular. At least one publication states he invented the game as well.
