# Killer Sudoku vs Row Stack

The clearest difference is in-app purchases: Killer Sudoku at none against Row Stack's 10. Killer Sudoku also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Row Stack sells 10 one-off in-app purchases. Killer Sudoku asks for nothing beyond the download.
