1. An indoor golf game comprising:

  • a. an area defining a tee from which golf balls may be hit;

    b. a screen located forwardly of said tee area and adapted to receive indicia depicting any one of a plurality of scenes of a golf hole;

    c. means providing indicia depicting a map of said golf hole;

    d. means for sensing the flight characteristics of a golf ball struck from the tee toward said screen for providing information relative thereto;

    e. computing means responsive to said sensing means for receiving the information therefrom and for computing the theoretical free flight trajectory of the golf ball hit from the tee, said computing means including a first circuit for determining the distance the ball would travel in a first horizontal direction generally straight away from said tee, a second circuit for determining the distance that a ball would travel in a second horizontal direction transverse to said first direction and a third circuit for determining the distance a ball would travel in a third direction normal to both said first and second directions;

    f. spot-projecting means responsive to said computing means 1. for moving a spot of light on said screen and thus on the one of the plurality of scenes of a golf hole on the screen to provide a visual simulation of the computed theoretical free flight trajectory and 2. for projecting a spot of light on the map of a golf hole to indicate the point of termination of the computed theoretical free flight trajectory of the golf ball on the map, said spot projecting means including first, second and third systems for changing the projection of the spot of light on the screen to indicate the distance of the ball from the tee, the distance of the ball to either side of the tee and the distance of the ball above the tee, respectively; and

    g. means responsive to said computing means when the latter has determined that the theoretical free flight of the ball has terminated for thereafter causing said spot-projecting means to indicate said point of termination on the map, said means responsive to said computing means comprising, means for alternately connecting said first, second the third systems to said first, second and third circuits, respectively, to move the spot of light on the scene and for connecting said second and third systems to said second and first circuits, respectively, to indicate the point of termination of the theoretical free flight trajectory of the golf ball on the map.
