Collapsed
You get a cannon, a fixed number of cannonballs, and a castle that has to end up flat. Work out which piece is holding the weight, hit that one, and let gravity do the rest of the job for you.

About the game
Using your intuitive understanding of physics, challenge yourself to complete each of the 50 levels and bring about a collapse in this puzzle and logic game.
Select from three different types of cannonballs - normal, polished, or fire.
Each level contains structures made from a wide variety of individual pieces. Collapse houses, castles, and more with a varied selection of levels and components. Once every piece has been destroyed or has fallen to the ground, the level is completed. The more cannonballs you have remaining at the end of each level, the higher you will score!
Select from three different types of cannonballs - normal, polished, or fire.
- Normal: just a heavy piece of metal to lob at fortresses.
- Polished: launches at high velocity - perfect for taking out stubborn targets.
- Fireball: does exactly what you expect - sets wood on fire!
