# Smart Sudoku vs Sudoku·

The clearest difference is price: Sudoku· at Free against Smart Sudoku's $0.99. Sudoku· also leads on ratings volume (17K vs 3) and update cadence (every 2 months vs every 9 months). Smart Sudoku's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On review sentiment, in-app purchases, device support and iOS requirement there is nothing between them.

Sudoku· is free to download; Smart Sudoku costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Smart Sudoku holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sudoku· has 17K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 60% of Smart Sudoku's written reviews are positive against 66% of Sudoku·'s, so the app with the better star average is not the one people write more warmly about.

Smart Sudoku ships an update every 9 months, Sudoku· every 2 months. The most recent releases landed on October 20, 2026 and October 25, 2026 respectively.
