About the game
Build stable towers across eight original block-stacking challenges.
Choose each block position and angle, drop it onto the platforms and let gravity and collisions settle the structure.
Complete the prescribed stack and reach its height target without losing a block.
Same-device two-player duels alternate placements: the player whose drop collapses the stack loses, and a stable twelve-block tower draws.
Matter.js supplies the physics; Three.js 3D and a playable 2D fallback share the same game state.
Pause, resume, replay any challenge and keep progress and challenge records on this device.
Keyboard and touch controls work without an account.
This is an original arcade game, not structural engineering software or online multiplayer.
