A topper construction for a gaming device or pinball machine, or similar article, has an illuminated pointer/director that utilizes a master-slave, driver-follower arrangement of magnetically linked elements to move over a display field in a pre-programmed manner to cue the player as to attainable goals and places. The master-driver is driven by a dual rack system controlling movement on X-Y axes, or by a cranking mechanism driven in an orbital or circular pattern. The pointer/director is hidden from the player's sight until the bonus round/feature begins.
