Welcome to Whack Stack! A colorful 3D physics puzzle game where stacked materials, tall towers and unstable buildings are waiting to be knocked down. Aim your cannon, fire the shot, and watch the structure collapse piece by piece. Smash every stack, clear the site, and finish each level with one perfect cannonball. A SITE FULL OF STACKS TO SMASH Stone blocks, wooden boards, heavy crates, steel barrels and fragile parts are stacked high and ready to fall. Every scene is a new build site: stone walls, steel frames and heavy material stacks, all built to test your aim. Load the cannon, pick your angle, and blast the whole thing down in one satisfying wave of destruction. SIMPLE MECHANIC, CLEVER PHYSICS PUZZLE The mechanic is simple: aim, shoot, smash. But every stack is a real physics puzzle. Some stone blocks hold the whole structure together. Some crates and barrels only shift. One fragile piece can break, trigger a chain reaction and drop the whole stack. Shoot without aiming and the structure just shakes. Find the weak point, control the angle and the power, fire the perfect shot and let the destruction do the rest. WHY YOU'LL LOVE WHACK STACK! • Simple cannon gameplay: aim, shoot and smash the stack • Satisfying 3D physics destruction, with every block, board and piece falling in real time • Colorful destruction scenes: stacked towers, stone walls, bridges and tricky structures • Smash stone blocks, wooden boards, crates, barrels and fragile parts • Destructive chain reactions that knock a whole building down in one blast • Clever puzzle challenge: read the scene, find the weak point, fire the perfect cannonball • Fun, chaotic cannon physics with new levels and rewarding destruction • Short, satisfying levels, perfect for a quick smash session • Easy to play and learn, tricky to master EVERY SHOT COUNTS Aiming is a skill. Control the angle, control the power, trigger the reaction. Hit one fragile block and the barrel stack pops. Knock one board down and the crates follow. Clear every object, break every obstacle, and the stage is yours. Each perfect shot rewards you with new cannons, new stone structures and bigger destruction. READY, AIM, SMASH! The cannon is ready. The stack is standing tall. Blocks are stacked, balanced and waiting to fall. Aim the cannon, hit the weak point, smash the structure and clear the stage. Can you smash every stack with the perfect cannon shot? Download Whack Stack! and start your first destruction puzzle today.
