Verdict
The clearest difference is in-app purchases: Sudoku· at none against Sudoku's 10. Sudoku· also leads on ratings volume (17K vs 1.1K) and iOS requirement (13 vs 15.6). Sudoku's advantage is ads (none vs shown) and review sentiment (95% vs 66%). On price, rating, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Sudoku sells 10 one-off in-app purchases. Sudoku· asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.8 for Sudoku against 4.7 for Sudoku·. That said, the two scores are not equally well evidenced: Sudoku· has 17K ratings behind it against 1.1K, so its average is the more settled of the two. Written reviews are what separate them: 95% of Sudoku's written reviews are positive against 66% of Sudoku·'s.
Sudoku ships an update every 3 months, Sudoku· every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
