Stackapult

Stack it. Launch it. Smash it!

Stackapult is a physics catapult game with a twist: you build your own ammo. Drop sliding slabs to stack the tallest tower you can, then your catapult hurls it at the enemy castle. The better you stack, the harder you hit!

🧱 STACK YOUR AMMO
Time each drop as the slabs slide back and forth. Land PERFECT drops in a row to chain combos and build a mighty projectile. Miss, and your tower shrinks!

🎯 AIM AND FIRE
Set the angle and power, check the trajectory and let it fly. Watch walls crack, towers wobble and whole castles crash down with real physics.

🏰 36 CASTLES TO CONQUER
Siege castles across three biomes:
• Forest – classic fortresses to get your aim in shape
• Snow – slippery ice palaces
• Volcano – explosive TNT strongholds

Take down the King, defeat every guard and save slabs to earn up to 3 stars per castle.

⚔️ THE CASTLE FIGHTS BACK
Enemy ballistas fire bolts at your catapult and your slab pile. Shielded guards, strong winds and tougher walls will put your strategy to the test.
