Golf simulator

The present invention provides a golf simulator comprising a launch area facing a screen at which the ball is driven and used to display part of a golf course. Sensors detect the impact of a ball on the screen, and/or flight towards it, and/or club head trajectory. The launch area is a playing surface panel tiltable by a displacement device, to provide a desired slope angle alpha and slope direction beta relative to a driving direction. A computer is connected to the sensors and displacement device, and programmed to control display of the course, based on its topography, and position of the launch area, and compute an estimated ball trajectory, ball lie based on the estimated trajectory and landing zone topography. The computer then controls the screen display and displacement device so that the next drive can be played from a realistic lie.
