# Crazy Math vs Sudoku

The clearest difference is update cadence: Crazy Math at daily against Sudoku's weekly. Crazy Math also leads on iOS requirement (11.0 vs 15.1). Sudoku's advantage is ratings volume (23 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Crazy Math sells 5 one-off in-app purchases and Sudoku sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Crazy Math against 4.9 for Sudoku. That said, the two scores are not equally well evidenced: Sudoku has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Crazy Math ships an update daily, Sudoku weekly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
