Sudoku Harmonic

This is Sudoku, reimagined as a gift for your senses.
Sudoku Harmonic transforms the classic puzzle you love into an immersive sonic experience. Each number (1 - 9) plays its own Solfeggio frequency (174 Hz – 963 Hz), turning every move into a moment of sound that draws you deeper into focus and flow.
This is the puzzle game you'll actually want to keep playing - not out of habit, but because it feels genuinely uplifting.
Why players are hooked:

- It's mentally engaging without being draining
- You finish sessions feeling centered, not depleted
What makes it different:
Each number triggers a specific Solfeggio tone, creating a harmonic soundscape as you play. The experience supports relaxation, mental clarity, and mindful focus - making this a puzzle game that actually enhances your state of mind rather than just filling time.
