Verdict
The clearest difference is in-app purchases: Sudoku· at none against *SUDOKU's 10. Sudoku· also leads on update cadence (every 2 months vs every 33 months) and ratings volume (17K vs 113). *SUDOKU's advantage is ads (none vs shown) and review sentiment (90% vs 66%). On price, rating and device support there is nothing between them.

On the App Store both sit at effectively the same score — 4.8 for *SUDOKU against 4.7 for Sudoku·.

Written reviews are what separate them: 90% of *SUDOKU's written reviews are positive against 66% of Sudoku·'s.
*SUDOKU ships an update every 33 months, Sudoku· every 2 months. The most recent releases landed on October 22, 2026 and October 21, 2026 respectively.
