The term "three-cushion" is commonly used in the game of billiards, referring to a shot where the cue ball must hit three cushion walls before making contact with the intended object ball. However, there are several synonyms that can be used interchangeably with this phrase. These include "three-rail", "three-bumper", "three-cushion billiards", "three-cushion caroms", and "three-cushion shots". Each of these terms refers specifically to the same type of shot, where the ball must hit three cushions before contact is made. Regardless of the term used, mastering the art of the three-cushion shot requires skill, precision, and practice.
