Physics meets perfect aim
Cannonballs 3D — Aim, Fire, and Bring the Building Down
Cannonballs 3D puts you behind a cannon aimed at a building that needs to come down — completely down. Line up your shot, fire, and watch real physics take over as the structure cracks, tips, and collapses piece by piece. The catch: you only get a limited number of cannonballs per level, so wild shots waste ammo you'll need later.
Play well and you'll earn power bombs — bigger, nastier ammo that can crack open the toughest, most stubborn structures in one hit. Every level ends the same way: nothing left standing, no pieces still balanced on the platform. Cannonballs 3D is free to play in the browser, no download required, and simple enough for any age to pick up and start demolishing.
Four shots to know
How to Play Cannonballs 3D
Line up the cannon, spend your ammo wisely, and leave nothing balanced on the platform.
- 01
Aim the cannon
Move your mouse, or drag a finger on touchscreen, to line up the cannon with the part of the structure you want to hit.
- 02
Fire
Click the left mouse button, or tap the screen, to shoot a cannonball.
- 03
Watch the physics do the work
A good hit sends pieces tumbling; a bad one wastes a shot you can't get back, since ammo is limited.
- 04
Use power bombs on the tough spots
Play well enough and you'll earn power bombs, strong enough to crack open the parts a regular cannonball can't budge. Clear every piece off the platform to finish the level.
