# Sudoku Cam vs Nuddle

The clearest difference is rating: Nuddle at 4.9 against Sudoku Cam's 4.2. Nuddle also leads on update cadence (weekly vs fortnightly). Sudoku Cam's advantage is in-app purchases (none vs 3). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Nuddle sells 3 in-app purchases, starting at $4.99 per month. Sudoku Cam asks for nothing beyond the download.

Nuddle holds the better App Store score, 4.9 against 4.2. Both are backed by a comparable volume of ratings — 5 and 8 respectively. Written reviews complicate that: 50% of Sudoku Cam's written reviews are positive against 43% of Nuddle's, so the app with the better star average is not the one people write more warmly about.

Sudoku Cam ships an update fortnightly, Nuddle weekly. Both last shipped on November 3, 2026.
