Apparatus for a shooting game wherein targets are launched from a launching station toward a shooter. Launching conditions can be varied and are selected in a manner hidden from the shooter. A timer is actuated when a target is launched and deactuated when the shooter fires at the target with the shooter being awarded a score which is inversely proportional to the time lapse between launch and firing. No score is awarded if the target is not hit by the shooter.
