Carom billiards
A new game appeared in 1879, called the champion's game or limited-rail. The champion's game is considered an in-between game—between straight rail and balkline—and was designed to stop the rail nurse. The game uses diagonal lines—balklines—drawn at the table's corners to indicate that if balls were inside those lines, points could not be scored, thus "cutting off four triangular spaces in the four corners, [taking] away 28 inches [711 mm] of the 'nursing' surface of the end rails and 56 inches [1422 mm] on the long rails." Despite its differences from straight rail, the champion's game only expanded the areas of the table where many points in a row could be scored before the balls had to be moved to a new position. This was not sufficient to stop nursing.
