I am trying to do this d*** arcade sequence for someone and there is absolutely no way it's working out. I can get 17 but that's it. The movement is so jerky that the game either over shoots the target or if I move slow I can't get enough fast enough. What's the trick besides putting my fist through the monitor? Oh and how come if you're supposed to get a free game - it still charges you? Is this another bug???

The secret is to tap the keys rather than press. Don't jerk from one side to the other but wait until the next lot of ducks appear. You may also find that the next lot come up where you've just hit so wait a sec. Work your way along the line. Someone told me to mark on your screen what level you should be aiming for as that is the main problem at the start. Unfortunately you have to hit every one, as if you didn't know! I found it helped turning the sound off as it just made my heart pound even more. Enjoy.
