The auto clicker I recommend is the OP Auto Clicker 3.0, since it doesn't have any type of virus (if you don't install it on an Indonesian page).

This are the settings


Is Basically all default but the click interval is set to 1 milliseconds and the click types are double clicks.

- Start new game

- Build this contraption:
- Spawn a bunch of versions of Hitler in the contraption
- Press Q and select the hand-icon using your scroll wheel
- Press 3 to access the rifle
- Start the auto clicker (F6) and shoot Hitler
- Make sure they wont move away from your crosshair
- Do something else (I went to sleep and had 100.000.000 points the next morning)
- You can close the auto clicker if you want to, you don’t need it anymore

- Press Q and select the hammer-icon with your scroll wheel
