A 3D Tetris experience built with Three.js, featuring realistic PBR materials, HDRI environment lighting, bloom post-processing, and a clean glassmorphism UI.

• Realistic 3D Rendering : PBR materials with clearcoat, HDRI environment reflections, soft shadows, and UnrealBloom post-processing
• Full Tetris Gameplay : SRS rotation with wall kicks, 7-bag randomizer, hold piece, ghost piece, lock delay, DAS
• Visual Polish : Particle effects on line clear, emissive block glow, camera drift, ambient starfield
• Sound Design : 8 game sound effects + atmospheric ambient background music
• Clean UI : Glassmorphism panels, smooth animations, score/level/lines tracking, next piece queue, hold preview
• Controls : Full keyboard support with DAS (Delayed Auto Shift)

• Three.js r160 — 3D rendering engine
• Web Audio API — Sound playback
• Vanilla JS / CSS / HTML — No build tools required

All assets are free to use:

# Clone the repository
git clone https://github.com/abhirupvgunakar/tetris.git
cd tetris

# Start a local server
python3 -m http.server 8080

# Open in your browser
open http://localhost:8080

Note: You must use a local server (not file://) because the game uses ES modules and fetch for assets, which require proper HTTP origins.
