A method for practicing a billiard shot includes defining a position for each particular one billiard ball within the plurality of billiard balls on the surface of the billiard table, using a defined device having a defined body, selectively securing each device to the surface of the billiard table with each ball within the cavity of the corresponding device in its first position, taking a first billiard shot, replacing each of the two or more billiard balls to their first position on the surface of the billiard table, and taking a second billiard shot including the replaced two or more billiard balls.
