In this physics-based game, your goal is to kill the guards by destroying the blocks with cannon balls. The broken blocks have to get in direct contact with a guard to kill him.
You have a limited number of shots, so you have to use them wisely. Careful not to hit the hostages!
You can also collect treasures for additional points. To get higher scores and more crowns, you have to hit the castle at the most strategic locations.
