# Sudoku vs Kaizen Sudoku

The clearest difference is in-app purchases: Sudoku at none against Kaizen Sudoku's 4. Sudoku also leads on ads (none vs shown) and iOS requirement (12.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Kaizen Sudoku sells 4 one-off in-app purchases. Sudoku asks for nothing beyond the download.
