A target game or practice device using a movable beam from a light projector (e.g. gun) and a target that releasably carries one or more preplaced target objects. The target objects are selectively released from the target and fall when struck by the light beam projected by the gun. In a preferred construction, the target objects are held to a target board by the force of electrostatic attraction, and the electrostatic charge is selectively dissipated by a photoconductor that is rendered more conductive when illuminated by the projector light beam. In other embodiments the target objects or support contains a light producing or scintillating material that regenerates light when struck by the projector light beam. In still further embodiments, the target support further, or alternately includes an electroluminescent or light emitting layer to generate light at the position of impingement of the projector light beam in response to a photoconductive layer at that position being rendered more conductive by the light to apply a power source to the electro-responsive light emitting layer and thereby visually indicate the position in a persisting manner.
