Carom billiards
In the balkline games, rather than drawing balklines a few inches from the corners as was done in the champion's games, the entire table is divided into rectangular spaces. This is done by drawing balklines a certain distance across the length and the width of the table. The lines are drawn a number of inches parallel from each rail. This divides the table into eight rectangular areas called "balk spaces". Additionally, rectangles are drawn where each balkline meets a rail, called anchor spaces. The anchor spaces were added to the game to stop nursing techniques that developed especially for the challenges of balkline without them.
