Sudoku a Day vs Sudoku.coach
We make Sudoku a Day. This comparison is based on the linked official product information, checked on 11 September 2026. It is not an independent scored review.
Both sites let you combine playing with learning. Choose based on the task: a daily puzzle, a guided learning path, practice of one technique or a particular paper layout.
Compare the available journeys
| Your task | Sudoku a Day | Sudoku.coach |
|---|---|---|
| Start playing | Daily browser puzzle with five difficulty choices; separate iPhone app. | Browser play alongside learning and construction tools. |
| Learn in a sequence | Beginner course and a suggested practice routine. | Campaign arranges lessons and exercises into chapters. |
| Practise one technique | Consult an existing lesson while learning; daily puzzles are not guaranteed to contain a chosen pattern. | Practice mode provides positions for selected techniques. |
| Print puzzles | Daily sheets and weekly PDF packs, with paper and layout choices. | Print mode offers single or mixed difficulty, custom puzzles and layout controls. |
For a specific learning goal
If you want repeated opportunities to apply one deduction, investigate Sudoku.coach's practice mode. If you want to organise a daily attempt and review it afterward, try our practice routine. You can use more than one resource: studying a technique does not require giving up the puzzle source you enjoy.
For paper solving
Both have a paper route. On our site, preview the chosen PDF and check its date coverage and answer-page description. In Sudoku.coach's print tool, review the selected difficulties, layout and page count before printing. Compare the actual previews for writing space rather than choosing by a feature count.
Check your device and session needs
Try notes, erasing and the available help on the screen you will use. If offline access or continuing on another device matters to you, test that workflow in the chosen version. Our iPhone app and browser game are separate experiences; a feature of one should not be assumed for the other.
