Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
