Place soft, glowing cubes instead of numbers — same logic, calmer surface. Each solve unfolds over slow, ambient dub-electronica with warm tape-echo textures, and a tone for every placement. Made for the moments between things.

What Makes It Different
Classic sudoku rules — every puzzle solvable with standard technique alone. No guessing, no forcing chains. Just thinking, in colors and tones.
Nine carefully tuned colors replace 1–9. Each color has an optional symbol overlay for accessibility, so the game is fully playable for colorblind players.
One new puzzle every morning — the same for every player, worldwide. Build a streak and come back tomorrow. Today's Daily Challenge is always free.
Beyond the classic 3×3 boxes: irregular, interlocking regions that bend the same logic into new shapes. The daily turns Nonomino every Tuesday and Saturday — premium unlocks unlimited play.
Casual to Master, drawn from a curated library. Every puzzle is hand-graded for fairness — classic technique only, never guessing.
Slow, ambient dub-electronica with warm tape-echo textures. Each placement adds a tone, each finished row a chord — the whole session becomes its own quiet score. Bring headphones.
The board has weight in your hand. The palette taps, cubes snap into place, completed rows ripple, conflicts pulse, removals click — every interaction answered in touch.
Duplicates are flagged but never blocked. The puzzle trusts you. A two-tier hint system offers a soft nudge or a single filled cell when you want it — always free, never paywalled.
No accounts, no servers, no in-app tracking. The whole game runs offline. Your progress, your stats, your data — all on your device, always.
Four Difficulty Tiers
Every tier shares the same color-logic mechanic. The difference is how deep the chains go — pick the one that fits the time you have.
Casual
A gentle starting point. Most cells unlock through naked singles and direct elimination.
Medium
Classic sudoku rhythm. Hidden singles and pair logic come into play.
Hard
Deeper chains. Locked candidates and triples reward careful pencilmarks.
Master
Full-width logic. X-wings, swordfish, and the long view — still always solvable without guessing.
New to sudoku? A gentle 4×4 Mini teaches the rules first. And every tier can be played in classic Normal boxes or irregular Nonomino regions.
