GEARBOX SYMPHONY
Build machines that make music
Somewhere in a brass-plated factory, a collection of musical blueprints has gone missing. The machines are silent. The gears have stopped turning. Somebody needs to rebuild them — and that somebody is you.
Your job? Listen to each blueprint, figure out what goes where, and piece together a mechanical orchestra from scratch. No sheet music. No instructions. Just your ears and a box full of tools.
━━━ HOW IT WORKS ━━━
🎵 STEP 1: Listen to the Blueprint — that's your target melody
🛠️ STEP 2: Place tools onto the grid and try to match the pattern
⚡ STEP 3: Hit POWER ON — the playhead sweeps and strikes your tools
⭐ STEP 4: Earn at least 2 stars to clear. 3 stars if you're that good.
━━━ YOUR TOOLBOX ━━━
🔨 Hammer: A sharp metallic clang — your main percussion.
🪗 Bellows: A warm breathy "whoosh" — like a pipe organ breathing.
🌀 Spring: A bright bouncy "boing!" — playful and fun.
⚙️ Gear: A mechanical click-clack. Perfect for filling gaps.
🔱 Tuning Fork: A clean, sustained tone. The closest to a real note.
━━━ THE FACTORY ━━━
Floor 1 — The Brass Workshop: 5 levels to teach you the ropes. Small grids, simple patterns.
Floor 2 — Steam Powered: Bigger grids, trickier melodies. You'll start second-guessing yourself.
Floor 3 — Crystal Harmonic: The final floor. All 5 tools, complex patterns.
━━━ FREE PLAY ━━━
Beat Floor 2 and you unlock Free Play — same puzzle, your rules. Crank up the grid width, limit your toolbox, or go all-out. Blueprints get randomly generated every time, so no two rounds play the same.
━━━ CONTROLS ━━━
🖱️ / 📱 Click or Tap. That's it.
Click a tool, click the grid to place. Click the eraser to remove. Works on computers, phones, and tablets.
