## What is Free Sudoku?

Sudoku the way it should feel: quiet. 
No disturbing ads you need to watch first. 

Zen Sudoku is a completely ad-free sudoku on warm paper tones, with
serif numerals and ink-brush illustrations. No accounts, no tracking,
no internet connection at all, the app cannot interrupt you, because
it has nothing to interrupt you with.
Whether you are a beginner or expert, we got you!

THE APP THAT TEACHES
The hint button never just hands you an answer. It names a real solving
technique, shows you where to look, and only fills in a cell if you ask
it to. It reads your pencil marks, warns when one is impossible, and
nudges you to mark the right area when a pattern is hiding. Tap "what
is this?" on any technique for a plain-language lesson, from naked
singles all the way to X-wings and Y-wings.

EVERY PUZZLE IS FAIR
Puzzles are generated on your device and verified by the same logic
engine that powers the hints: every puzzle can be solved by pure
reasoning. No guessing, ever. Four difficulties, Expert really means
expert techniques, not trial and error.

THE DETAILS
• Pencil notes with a dedicated notes row, no mode switching
• Completed numbers fade on the pad
• Auto-save: close the app mid-puzzle, resume exactly there
• Statistics, best times, total play time
• Light and warm-dark themes
• Optional background music, gentle click sounds and haptics —
all respectful of your mute switch and your own music

Free forever. 
If it brings you a little peace, 
there's a small tip jar, thank youuuuu
nothing unlocks, 
the whole app is already yours.

Lets make this world a beter place.
