Project Overview
Sudoku Harmonic transforms the classic number puzzle into a healing, meditative experience. Each number from 1 to 9 is mapped to a specific Solfeggio frequency (174 Hz - 963 Hz), creating an immersive sound therapy session as you play. Brain training meets nervous system regulation.
The Frequency Map
- 1 → 174 Hz — Foundation and physical healing
- 2 → 396 Hz — Liberation of fear and guilt
- 3 → 417 Hz — Facilitation of change
- 4 → 432 Hz — Universal harmony
- 5 → 528 Hz — Transformation and DNA repair
- 6 → 639 Hz — Relationship healing
- 7 → 741 Hz — Awakening intuition
- 8 → 852 Hz — Spiritual order
- 9 → 963 Hz — Divine consciousness
Features
- Real-time frequency synthesis — tones generated on-device, low latency
