A training apparatus and method for games such as billiards is provided wherein the training apparatus includes a projector body supported by an elongated trunk. The apparatus can be positioned on a playing surface where the projector body is vertically above an object ball that can be received b y alignment stops for properly positioning the object ball below the projector body. By activation of electronics in the projector body, a path can be projected that is aligned with and indicates the intended object ball path. This object ball path or line typically will line up with and be a path to a desired pocket for the object ball to be caused to enter. A second path from the projector body can be projecte d as a target strike location, which can be a vertical target line or a predetermined geometric configuration, can be projected onto the surface of the object bal l to indicate a desired contact or strike point, also referred to as an impact location, at which the cue ball should strike the object ball to cause the object ball to move along the intended object ball path. Reference lines can be emitted fro m the projector body to indicate the resultant cue ball path subsequent to striking the object ball at the vertical target line. An incandescent light or a holographic image can be projected from the projector body behind the object ball to provide a ghost ball or image representing the target impact location for the cue ba ll to strike the object ball. As a result, a user may select an object ball target objective, receive visual input on the optimum impact location in various formats, and receive feedback information on the resultant cue ball path.</S DOAB>
