Castle Destroyer is a fun game that is very easy to play. The goal of the game is to see how quickly you can destroy each castle you are shown. When the castle is shown to you, use your mouse button to click on an area. Then drag our mouse in which ever direction you want and a line will appear in that direction. Once the line has been drawn the castle will either be destroyed completely or only a part of it will be. It all depends on where you place your mouse and draw the line.
