Hum Puzzle: Voice Pitch Game

Hum Puzzle is a puzzle game you play with your voice. Hum a note and the chamber moves: lifts rise, gates slide open, planks tip and drawbridges fold down. Roll the ball to the glowing door.

Set to your voice
A short humming check finds your comfortable low and high notes, so a deep voice and a high voice can both reach every goal. Pieces answer to low, middle or high notes, and the pitch meter shows where your hum sits.

30 chambers in three chapters
• The Quiet Halls: lifts, gates, tilting planks and drawbridges, one at a time
• The Echo Works: note locks, staircases of lifts, a catapult and pieces that stay where you set them
• The Deep Vaults: taller chambers with checkpoints, where every piece works together

Real rolling physics
The ball rolls, bounces and rides each platform smoothly. Time a note change while it rolls, or hold a steady note to keep a bridge level.

Stars and best times
Every chamber has a target time. Beat it for three stars.

Play your way
