Master the Art of Stacking in 3D

Stack 3D is a minimalist yet challenging physics-based game that tests your timing, precision, and focus. Built using the powerful Three.js engine, this game brings a modern twist to the classic tower-building genre. The goal is simple: stack the moving blocks as high as you can without missing. Each perfect placement rewards you with a satisfying "ding" and maintains the size of your block, while any overlap will result in the excess part being trimmed away, making your tower increasingly narrow and difficult to manage.

As you ascend higher into the sky, the speed of the blocks increases, demanding faster reaction times and a steady hand. The vibrant, procedurally generated colors provide a beautiful visual progression as you climb. Whether you're looking for a quick mental break or a competitive challenge to beat your high score, Stack 3D offers a seamless, high-performance experience directly in your browser with no installation required.

Gameplay Instructions

• Place Block: Tap the screen or click your mouse to drop the moving block onto the stack.
• Survival: The game ends when you miss the stack entirely.

Scoring Rules

Your score is based on the number of blocks successfully added to the tower. Perfect hits keep the tower stable, while partial hits make it harder to score subsequent points as the area of placement shrinks.

Pro Tips

Use steady timing and focus to beat high scores! Watch the shadow of the moving block to predict exactly when it will cross the center of your tower. Chaining perfect hits together is the only way to build a truly record-breaking skyscraper.
