Boom Stack Smash

Some games ask you to build things. Boomstack gives you a cannon. Take aim, find the weak point, and fire. Every level is a handcrafted stack of wood, stone, ceramic, steel, and other materials just waiting to come crashing down. One perfect shot can start a chain reaction that destroys everything. Or miss the weak spot… and watch the tower stand there like nothing happened. REAL PHYSICS. REAL COLLAPSES. Nothing is scripted. Blocks crack, fall, roll, collide, and knock other pieces over based on physics — so every demolition can play out differently. Find the right angle. Choose where to shoot. Then watch gravity finish the job. WHAT’S WAITING • Handcrafted levels across island after island • Locations ranging from a seaside carnival to the canals of Venice • Three-star challenges that reward smart, efficient shots • Different materials with their own weight and behavior • Powerful ammo and boosters for tougher structures • A prize machine packed with coins and rewards • Endless mode for chasing bigger streaks and higher scores • New stacks to smash as you progress EASY TO PLAY. HARD TO PERFECT. Boomstack is built for quick, satisfying sessions: • Portrait mode • One-handed controls • Short levels • Simple aiming • Offline level play • Plenty of room to master the perfect shot You don’t need complicated controls. Just aim, fire, and bring it all down. How many shots will you need? Download Boomstack and start smashing. Boomstack is free to download and play, with optional in-app purchases and an ad-free upgrade.
