A game in three quiet moves

  1. 01

    Pick a cell

    Click any empty square. The row, column, and box light up so you can scan at a glance.

  2. 02

    Type a number — or a note

    Press 1–9 to fill, or toggle notes mode to pencil in candidates. Conflicts turn red so you catch mistakes early.

  3. 03

    Finish, share, return tomorrow

    A clean solve auto-saves your stats. Share a link, then come back for a fresh puzzle tomorrow.

What's not here

A short list of things other sudoku sites add. We deliberately don't.

  • No signup

    Open the page and play. No email, no account, no password to forget.

  • No ads

    No banners, no interstitials, no sponsored puzzles. The page is just the puzzle.

  • No tracking

    No third-party analytics, no fingerprinting, no behaviour profiling. Your game stays in your browser.

Quiet features that earn their place

  • Bilingual

    English and 中文, one click. The page remembers your choice on this device.

  • Light and dark

    Cream-and-forest by day, forest-and-cream by night. Or follow the system.

  • Auto-save

    Every move is written to your browser. Refresh, close the tab, come back tomorrow — same game resumes.

  • Keyboard first

    Arrow keys to move, digits to fill, Ctrl+Z to undo, N for new, T for theme, L for language.

Today's puzzle is waiting.

Free forever. Open the page, take a breath, fill a row.
