# Mister Sudoku vs Crazy DNA

The clearest difference is review sentiment: Mister Sudoku at 90% against Crazy DNA's 29%. Mister Sudoku also leads on ratings volume (108 vs 1) and update cadence (every 4 months vs every 17 months). Crazy DNA's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Mister Sudoku sells 1 one-off in-app purchase. Crazy DNA asks for nothing beyond the download.

Crazy DNA holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mister Sudoku has 108 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of Mister Sudoku's written reviews are positive against 29% of Crazy DNA's, so the app with the better star average is not the one people write more warmly about.

Mister Sudoku ships an update every 4 months, Crazy DNA every 17 months. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
