  Castle destruction games are a type of physics game normally found for free online. They come in several varieties and usually require you to precisely throw stones or other objects at castles to knock them down. Some are simple, some are more complicated, and some even let you build your own castles to knock down.
  
  

Castle Clout

• Use a trebuchet to throw stones at the castle on the opposite side of the screen. As you move up in level, you'll unlock larger stones to throw at the castles as well as large and small blocks of steel and lead.
  
  

Sieger

• Use your limited amount of ammunition to destroy castles and defeat your enemies. Battle through 25-plus levels of increasing difficulty. You can also build your own castles in this game and play against others.
  
  

Old Cannon

• You have three shots of your cannon to knock the castle down until its highest level of debris is below the black line on the screen.
  
  

Lords 3 Catapult

• Using a catapult, shoot down a castle with boulders to destroy it. You must hit the castle's keep to complete a level, and you're awarded bonus points for hitting certain items like enemy knights and the castle's flag. You have to watch out for your own knight, though, or you'll lose a life.
