Castle Wreck is a free arcade game which can be used as a relaxation method before you're going to start work, school, and other stressful activities. The gameplay contains various different levels where your purpose is to destroy various castles by shooting cannons. You can aim on horizontal with the first tap, then aim vertically with another tap, and the cannon also shoots by itself.
The cool thing about this mobile game is the ability to see the destruction done by your cannon right after a shot is performed. In terms of visuals, Castle Wreck places the player camera right behind the actual cannon, and the view changes at specific moments when you can see the castle falling apart.
