Stack Tower 3D

🏗️ Welcome to Stack Tower 3D — Pure Arcade Precision! 🎯

Stack Tower 3D is a minimalist 3D stacking arcade game that distills the joy of precision into a single tap. No menus, no distractions — just you, a sliding block, and the endless pursuit of the perfect stack.

🎮 How to Play
A colorful block slides back and forth above your tower. Tap the screen to drop it. The overlapping portion stays — everything that hangs over the edge gets sliced clean off and tumbles away as physics rubble. Miss entirely? The tower crumbles and your run is over. The sliding axis alternates between X and Z directions, keeping every layer uniquely oriented.
