on sudokuwiki.org
SudokuWiki, Andrew Stuart's site about sudoku strategies, publishes a numbered sudoku every day in four grades of difficulty, with an archive of earlier puzzles. You can solve in the browser with a player that handles notes well, or print the grid. The site's solver can explain any step you are stuck on.
About Daily Sudoku (SudokuWiki)
SudokuWiki.org is a reference site for sudoku solving techniques, built around Andrew Stuart's online solvers and strategy articles. The Daily Sudoku is its main daily puzzle and has been running for a long time: the number passed 6,800 in October 2026. Every visitor sees the same numbered puzzle on a given day.
The page offers four grades each day, so beginners and experienced solvers can each find a fitting grid, and an archive lets you go back to earlier days. The player supports pencil notes, a prefill option that fills every empty cell with all candidates for those who prefer elimination, automatic clearing of notes, a number pad for phones and keyboard control, and you can print the puzzle instead.
Because the site is built around teaching strategies, a stuck solver can open the puzzle in the SudokuWiki solver and see which named technique unlocks the next step.
It suits sudoku players who want a reliable daily grid at their own level and who are interested in learning advanced techniques.
How to play Daily Sudoku (SudokuWiki)

- Come back the next day, or catch up from the archive.
