As far as the partie libre is concerned the player is allowed to execute uccesively in the course of the same serie an unlimited number of cannons within the limit of the distance on the whole surface of the billiard except in the barred zones of the corner in which the game is regulated by the regulations of the articles 51 to 60.

The cadre disciplines give the opportunity to several kinds of matches depending on the fact whether they are played with one or two strokes of 47 or 71 centimetres with additional squares. (paper C-D)

1. On the playing surface one draws as fine as possible with chalk, in pencil or with ink lines which form quadrilaterals called cadres. (barred zone)
2. Moreover, one draws at the end of each of these lines and astride them small additional squares whereby one of the sides smooths with the internal side of the cushion. These small squares are named anchors.
3. The prescriptions of the articles 51 to 60 are applicable as far as the line of the cadre and the cadres are concerned are also valid concerning the lines of the anchor and the anchors.

1. Concerning the cadre of 47 cm one draws four lines which determine the following nine cadres on the billiard: three central rectangles within the length and six squares within the width. (paper C)
2. Concerning the cadre of 71 cm one draws three lines which determine the following six squares on the billiard: two central rectangles within the length and four squares within the width. (paper D)
3. As far as the cadre disciplines with two strokes are concerned the player does not have the right to execute succesively two cannons within the same cadre in the course of the serie without forcing at least one of the two object-balls to leave it by means of the second stroke.
