Castle Clout 3 Description: Castle Clout 3 pits you against some fragile-looking structures. You are in charge of a trebuchet, and your job is to destroy the people located on or in the structure. In order to do this, you will need to get perfect timing. You will use the left mouse click and click once to activate the swinging mechanism of the trebuchet, and then you will click once more to let go of the ball(s). If you time it just right, your hit should knock down the structure and crush anyone on or in it.
