Keys

| key | does | |---|---| | arrows / h j k l | move | | 1–9 | place a digit | | 0 / backspace | erase | | space | notes mode — then 1–9 pencils a candidate | | s | share this board | | n | new puzzle | | d | change difficulty | | ? | keys | | q | quit |

Your board is kept

Quit, close the terminal, or lose the tab — the board is still there next time. Only winning clears it. Press n when you want a fresh puzzle.

Sharing

Press s and the board's share code is copied to your clipboard:

Your friend gets the same puzzle from its starting position — not your half-filled grid — so you can race. The code is just the difficulty, the generator version and a 32-bit seed; there is no server involved.

Difficulty is graded, not guessed

Puzzles are generated, then solved with ranked human techniques. A puzzle is only called hard if it genuinely needs a pointing pair or a naked pair; easy falls to naked singles alone. Every puzzle has exactly one solution.

Tokens

Win while signed in and the server awards tokens — more for harder puzzles, more for faster solves. Sign in once with npx afk-arcade; sudoku shares that login.

There are no hints and no mistake highlighting. It's you and the grid.
