# Crazy Math vs Sudoku.com

The clearest difference is in-app purchases: Sudoku.com at none against Crazy Math's 5. Sudoku.com also leads on ratings volume (12 vs 1). Crazy Math's advantage is ads (none vs shown). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Crazy Math sells 5 one-off in-app purchases. Sudoku.com asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Crazy Math against 4.9 for Sudoku.com. That said, the two scores are not equally well evidenced: Sudoku.com has 12 ratings behind it against 1, so its average is the more settled of the two.
