Abstract: A laser bowling ball guiding apparatus includes a projector, a laser beam emitted from the projector, and a diverging lens or at least one movable mirror for receiving the laser beam and projecting the laser beam onto a surface of a bowling alley and onto bowling pins so as to display a proper release point, trajectory and impact point for a bowling ball to follow. The apparatus can also employ a control mechanism connected to the projector for controlling transmitting of the laser beam. The projector is generally mounted to a ceiling or on a tripod. The control mechanism is adapted to receive an input of information and is operable to calculate the proper release point, trajectory and impact point for the bowling ball to follow. The diverging lens converts and projects the laser beam into the form of a line onto the surface of the bowling alley and onto the bowling pins.
