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.

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.

Blast & Clear – Shoot, Smash, and Unwind! If you're looking for a stress‑melting shooting game that still gives your brain a little workout, this is it. Grab your cannon, take aim, and fire away at a platform full of targets. No complicated rules, no endless tutorials – just pure, satisfying demolition. Each level gives you a limited number of shots, so every trigger pull counts. Clear the platform, and you move on to the next challenge. Simple, punchy, and incredibly relaxing. How It Works You control a cannon at the bottom of the screen. Above you, a platform is stacked with various objects – wooden crates, ceramic pots, iron barrels, and more. Your job is to knock every single one of them off the platform using your cannonballs. Aim carefully, consider the angle, and fire! When a target gets hit, it tumbles and falls to the ground. Once the platform is completely empty of targets, you've cleared the level. No time limits, no pressure – just you, your cannon, and a pile of things waiting to be smashed. From Wood to Iron – The Challenge Grows At first, you'll face lightweight wooden crates that are easy to topple. A single well‑placed shot can send them flying. But as you progress, things get tougher. Ceramic pots are heavier and take more hits to break. Then come iron barrels – they're sturdy, stubborn, and require precise, repeated strikes. And it's not just the materials that change – the targets start stacking higher and higher. Towers of crates, piles of pots, and fortified stacks of barrels make each level a fresh puzzle of angles and force. Weight & Stacking – A Real Test of Aim The added weight changes everything. A heavy barrel on top of a crate might crush it if you hit the right spot – or it might stay put if you don't. You'll need to think about which target to hit first, which angle sends the most objects tumbling, and how to make the most of your limited ammo. Sometimes a single shot in the right place can trigger a chain reaction, toppling half the platform in one glorious explosion. Other times, you'll need to chip away piece by piece. Pure Satisfaction, No Rush There's no timer breathing down your neck. You can take all the time you need to line up your shot, study the stack, and plan your attack. Each successful hit feels incredibly rewarding – the satisfying crash of breaking objects, the clatter of debris, and the gradual clearing of the platform. It's the kind of game you can play for five minutes or an hour, and it always leaves you feeling relaxed and accomplished. Ready to Become a Master Blaster? With dozens of levels, each more challenging than the last, you'll never run out of things to smash. Progress through wooden villages, ceramic workshops, and iron fortresses. Upgrade your cannon, unlock new ammo types, and prove your aiming skills. Can you clear every platform with the fewest shots possible? Jump in, take aim, and start blasting your stress away – one target at a time!
