Every number sings. Solve color-coded Sudoku with gentle hints that teach you real techniques — and watch the puzzle bloom into light as you go. No ads, ever.
Lumina is Sudoku the way it was meant to feel: calm, colorful, and quietly brilliant. Every digit has its own color and its own musical note, so the board doesn't just challenge your logic — it lights up and sings as you solve.
Whether you're a complete beginner or a seasoned solver chasing Expert grids, Lumina meets you where you are: hand-crafted puzzles, gentle guidance, and a glowing aurora that grows brighter the closer you get to the solution.
WHY YOU'LL LOVE LUMINA
• A living aurora — the background blooms with light as your progress grows.
• Synesthesia — each number 1–9 has a signature color and a soft, consonant tone. Complete a row, column, or box and it rewards you with a little chime.
• Hints that actually teach — instead of just handing you the answer, Lumina names the real solving technique (Naked Single, Hidden Single, Locked Candidates, X-Wing and more) and explains the logic in plain language.
• Your solve becomes a song — finish a puzzle and replay your moves as a melody and a sweep of light.
EVERY LEVEL, EVERY DAY
• Four difficulties — Easy, Medium, Hard, and Expert — each puzzle guaranteed to have one unique solution.
• A fresh Daily Challenge every day, with a streak worth keeping.
• Smart pencil notes, unlimited undo and redo, and an optional mistake limit.
MADE TO FEEL GOOD
• Three beautiful themes: Aurora, Midnight, and Paper.
• Assists you control — highlight peers, matching numbers, and mistakes, or switch them all off for a pure challenge.
• Haptics and sound, tuned to your taste.
• Designed for one-handed play, Dynamic Type, and accessibility.
QUIET BY DESIGN
• No ads. No pop-ups. No accounts.
• Plays completely offline.
• No tracking and no data collection — your puzzles stay on your device.
Sit down, breathe, and let the numbers light up.
