Consecutive ball-to-ball cannons are limited to 25; on the completion of this number the break shall only be continued by the intervention of a hazard or indirect cannon. (Rule 13.)
Penalties.
If, after contact with another ball, striker's or any other ball is forced off the table, the non-striker shall add two points to his score. (Rule 18.)
For a foul stroke the striker cannot score, and his opponent plays from hand. His ball shall be placed on the centre spot, the red ball shall be spotted, and his opponent shall play from the D.
For refusing to continue the game when called upon by the referee or marker to do so, or for conduct which, in the opinion of the referee or marker, is wilfully or persistently unfair, a player shall lose the game. (Rule 18.)
PYRAMIDS.
This game is played by two persons with sixteen balls,—one white, and fifteen red. The latter are arranged in the form of a solid triangle, with its apex on the Pyramid spot (P in Fig. 1), and its base towards the top cushion and lying parallel thereto.
At the commencement of the game, one player leads off from the half-circle, and plays at any one of the red balls. Should he pocket one or more balls, he scores one for each red ball pocketed. He continues playing till he fails to score.
If a player gives a miss, or pockets the white ball, a point is taken off his score and he must replace one of the red balls he has previously pocketed; on the Pyramid spot, if unoccupied, or, if that be occupied, as near to it as possible in a line directly behind it. If he has not previously pocketed a ball, he owes one, and must pay it by replacing the first ball that he pockets later on.
