Abstract

A golf game apparatus that simulates a total golf shot distance based upon the actual flight time of a struck golf ball at a practice range and the linear flight distance of the ball to an initial impact position on an adjacent target area. The flight time and linear flight distance are used to simulate a roll distance which may be added to the linear distance to thereby produce the simulated golf shot total distance. A display positioned adjacent the tee area of the practice range may display a simulated golf hole layout with the simulated golf shot total distance indicated thereon for the player. The simulated golf ball roll distance may take into account a predetermined type of golf course surface upon which the struck golf ball initially impacts.
