    Abstract: A simulated radar game having a radar-like display screen with an illuminated circular rotating scanning line. A first set of programming switches may be used to establish one or more target positions on the screen corresponding to selected angular and radial positions with visual indication occurring each time a selected position is passed over by the scanning line. A second set of programming switches may be used to establish reference coordinates corresponding to desired angular and radial reference positions. Coincidence between a target position and a reference position causes a scoring indication.
