Just Sudoku · Just Play

Just Sudoku is sudoku without the noise. Sudoku rewards quiet attention. Just Sudoku does the same — it stays out of your way and lets the puzzle do the work. WHAT'S INSIDE — 2,000+ hand-rated puzzles, from gentle Beginner to true Grandmaster. — Twelve difficulty levels, each tied to a real sudoku technique: Hidden Single, Pointing, Naked Pair, X-Wing, XY-Wing, Forcing Chain, and beyond. — Rated using the industry-standard Sudoku Explainer system, so every puzzle's difficulty is honest — not a marketing label. — After every win, two taps: same level again, or step up. DESIGNED TO DISAPPEAR Just Sudoku is a quiet app. The interface is paper-warm and nearly monochrome. Numbers, a grid, and the few controls you actually need. It looks the same on day one as it does on day one hundred. PLAY YOUR WAY — Pencil-mark notes for working through candidates. — Three hints per puzzle, three mistakes before you start over. — Soft haptics that confirm your touch without shouting. — Cells related to your selection light up gently — same row, same column, same box, and any cell sharing the same number. PRIVACY BY DEFAULT Just Sudoku does not collect any personal data. It works completely offline. There is no account to create, no email to enter, no servers to talk to. The puzzles live on your device. FULLY LOCALIZED Available in: English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Deutsch, Italiano, Português (Brasil), Русский, العربية. For people who love sudoku itself.
