A billiard game machine is used for playing a billiard game. A player operates a dummy cue (19) to thrust a cue ball object displayed on the screen (9a) of a display (9) disposed at a position corresponding to a back part of a dummy billiard table (7) so that the cue ball object rolls on a table object displayed on the screen (9a) of the display (9) and hits against an object ball object. A dummy bridge (11) for supporting the dummy cue (19) so that the dummy cue (19) is able to move for longitudinal back and forth movement in a predetermined range is disposed on the dummy billiard table (7). The billiard game machine enhances the verisimilitude of the billiard game.
