Sudoku a Day vs Microsoft Sudoku
We make Sudoku a Day. This comparison uses the linked official listings and support documentation, checked on 11 September 2026. It is not an independent scored review.
Choose according to the kind of session you want: a classic daily grid, varied challenges or paper practice. Keep mobile-app features separate from browser features when comparing the two services.
Compare the activities
| Your priority | Sudoku a Day | Microsoft Sudoku |
|---|---|---|
| Daily play | A daily classic board with five difficulty choices. | The iPhone and iPad listing describes three daily challenges each day. |
| Game modes | The current browser player uses classic Sudoku rules. | The listing describes Classic and Irregular Sudoku with six difficulty levels. |
| Account features | Read the requirements on our leaderboard before participating. | The listing associates Microsoft sign-in with achievements and cloud progress across Apple devices. |
| Paper practice | Website PDFs, including packs with solutions. | This guide compares the mobile listing; it does not assume its features apply to paper exports. |
Sign-in and Premium are different
Microsoft's listing describes ad removal and access to earlier daily challenges as Premium subscription benefits. It says that mobile Premium does not transfer to other platforms. Review the current terms on the device you will use; signing in alone should not be treated as purchasing an ad-free offer.
When to try each
Try Microsoft Sudoku if the listed challenge modes or Irregular grids match what you want. Choose our browser game for a classic daily attempt, or the printable chooser when you want a sheet to keep beside you. Our variant guides explain additional rules but are not playable variant modes.
