## Review summary

Users praise the app’s beautiful, color-rich UI and broad difficulty options with helpful pencil/notes features, plus offline usability and a pro version to remove ads. However, many cite intrusive ads (including loud video and non-monetary ads) and ad-closing glitches, recurring timer issues that affect scores, and worries about updates/ongoing support. Overall, it’s a beloved, polished Sudoku experience with notable ad and reliability drawbacks.

- Wide range of difficulty levels plus helpful features like auto-pencil, color coding, and margin notes
- Reliable offline play and strong polish; option to remove ads via the pro version
- Long-standing favorite with steady improvements and high user satisfaction

### Cons

- Intrusive ads (loud, video ads, and even religious ads) and unresponsive ad closures
- Timer reliability issues (sometimes not starting or crashing, affecting scores)
- Ads reappearing after upgrades and concerns about lack of timely updates
- Limited customization options such as no toggle to disable sound or autocorrect
