## Description

Every puzzle has an answer.

A quiet sheet of paper and a problem that works out. sudoku is a minimal, restrained take on the classic — no ads, no tracking, no noise. Just you and the grid.

Warm paper white, a single Morandi accent, monospace numerals under a serif title. Open it and solve; finish and let it go quiet.

Four difficulties
Easy / Medium / Hard / Master. Master ships with world-renowned classic puzzles and a graded bank — from first steps to the very edge.

An AI coach that teaches you to think
Not just answers. Naked singles, hidden singles, naked pairs, pointing pairs, X-Wing — each technique highlighted right on the board, so you see the logic instead of being handed it.

Made for beginners, too
A four-step tutorial on the real board: from the rule to the deduction, then straight into your first game.

Paper mode
Solve like it's newsprint: no mistake limit, nothing flagged, nothing highlighted. The verdict is yours alone.

Tools that stay out of the way
Pencil notes, undo, erase, hints; instant conflict flags and soft region highlights — all switchable.

And more
• Bilingual English / 中文, switch anytime
• Five Morandi accent colors — pick your taste
• 17 illustrated guides, from the rules to master techniques
• Share a puzzle as a text token; challenge a friend on the same board
• Best times and full history
• Carefully tuned haptics and sound
• Fully on-device — your data never leaves your phone

Pay once, yours forever. No subscriptions, no consumables, no ads.

—
Independently designed and built. One person, quietly.
