Verdict

Who is it for

Real-world User Experience

Is it Worth Paying For?

Yes if you play daily. The free version is fully playable but ad-heavy; the reported ~$13/year ad-removal offers a cleaner, more focused experience. If ads don’t bother you or you play casually, the free tier suffices; regular players will likely value the upgrade.

How it Compares to Alternatives

Compared to Sudoku.com (Easybrain) and Brainium Sudoku, this matches core polish, offline play, and assists; it adds a 16x16 mode and competitive events some rivals lack. Andoku emphasizes advanced techniques and custom variants with fewer interruptions but a plainer look. Microsoft Sudoku offers themes and challenges but is more service-tied. Overall, this app balances accessibility and features well, with ads being its main trade-off versus premium or less ad-heavy alternatives.

Summary

Sudoku - Classic Sudoku Puzzle nails the essentials with clean controls, smart assists, and a difficulty curve that welcomes newcomers while challenging veterans—plus extras like 16x16, daily/weekly puzzles, and battle mode. It runs great offline and is actively maintained, though the free tier’s frequent ads and modest stats/training depth may irk purists. If you want a dependable, feature-rich Sudoku you can play anywhere, it’s an easy recommendation—consider the paid option if you value uninterrupted focus.
