Abstract
An aiming system for billiards and like games wherein a cue is provided with a switch-actuateable generator for causing a narrow collimated beam of light to emerge from the playing tip along the longitudinal axis of the cue. In the preferred embodiment, a laser generator is positioned within the handle portion of the cue and the light therefrom moves through a longitudinal bore along the length of the cue to emerge from an apertured standard playing tip. A billiard table is also disclosed containing a set of reflector elements mounted vertically within the overhang of the edge cushions of the table.
