# Sudoku ′ vs Sudoku ++

The clearest difference is review sentiment: Sudoku ′ at 81% against Sudoku ++'s 12%. Sudoku ′ also leads on ratings volume (38K vs 1). Sudoku ++'s advantage is ads (none vs shown) and update cadence (weekly vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Sudoku ′ sells 1 one-off in-app purchase and Sudoku ++ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sudoku ++ holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sudoku ′ has 38K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 81% of Sudoku ′'s written reviews are positive against 12% of Sudoku ++'s, so the app with the better star average is not the one people write more warmly about.

Sudoku ′ ships an update every 3 months, Sudoku ++ weekly. The most recent releases landed on October 18, 2026 and October 16, 2026 respectively.
