THE CAROM.
To make a carom, the player must cause his own ball to strike two or more balls in the same shot.
When he strikes his adversary’s ball, and either the light or dark red, he scores two.
When he strikes the two red balls, or, in billiard phrase, caroms on them, he scores three.
THE HAZARD.
There are two sorts of hazards—winning and losing.
A WINNING HAZARD is made by pocketing the adversary’s ball, or either of the red balls.
In the first case, the player scores two; in the second, he scores three.
When the player pockets his own ball it is a LOSING HAZARD. If his ball is pocketed after having struck the white or adversary’s ball, two points are added to the adversary’s score.
If the ball is pocketed after having struck either of the red balls, three points are added to the adversary’s score.
