Editor's take
Sudoku Puzzle is the workhorse of our sudoku hub, and that is a compliment. It does classic 9x9 sudoku across the standard difficulty ladder with all the fundamentals in place: clean grid, reliable note-taking, mistake feedback that you can tune to your preference, and instant new games. In our playtests it became the version we reached for when benchmarking other sudoku titles, precisely because it has no quirks to account for — the input is fast, the highlighting of related cells is helpful without being pushy, and the grids themselves are well-formed with honest difficulty ratings. It will not wow anyone with presentation, and it does not try to. For the large population of players who simply want a dependable daily sudoku in a browser tab — no account, no ads wall, no app install — Sudoku Puzzle is exactly enough, and being exactly enough for a daily habit is harder than it looks.

Strategy tips
Fill naked singles first, then pencil-mark cells down to two candidates — most medium grids fall to marks alone. Scan for the digit that appears most on the board; it is usually nearest completion. When stuck, re-check each 3x3 box rather than rows: errors and hidden singles hide in boxes more often.
