To play Lasergolf you need to have a Laserclub and its associated Tee base. If the Tee base is not attached to your computer, Lasergolf enters 'demo' mode and plays all the shots for you, using the course and the players you select.
If you'd like to get an idea of the graphics and the gameplay, you can download a demo version of the Lasergolf software from here. This will allow you to setup the game and to watch as it plays for you.
