About Whack Stack!

Welcome to Whack Stack!, a satisfying physics puzzle game where tall buildings, stacked blocks, and unstable towers are waiting to be knocked down.

Aim your cannon, fire the shot, and watch the structure collapse piece by piece. Bring down every stack and clear the stage with the perfect hit!

Whack Stack! is easy to play, but every level makes you think. Buildings are built with different shapes, some parts are stronger than others, and one well-placed cannonball can bring the whole tower crashing down. Look carefully, find the weak point, and smash each structure in the smartest way.

A PHYSICS PUZZLE WITH A BLAST

Every stack is a puzzle. Some blocks hold the whole structure together, some walls protect the weak spots, and some towers only fall when you hit the right place.

Shoot without thinking and the stack may only shake in place. Aim carefully, fire at the right point, and the whole structure can collapse in one satisfying chain reaction.

KNOCK DOWN EVERY STACK

The cannon is ready. The target is standing tall. Blocks are stacked, balanced, and waiting to fall.

Your job is simple:
aim the cannon, hit the weak point, and bring the whole stack down.

But every shot matters. Use the right angle, the right timing, and the right amount of power to clear the stage.

Can you smash every stack with the perfect cannon shot?
