# X vs Kirin Sudoku

The clearest difference is in-app purchases: Kirin Sudoku at none against X's 1. Kirin Sudoku also leads on ads (none vs shown) and iOS requirement (14.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. X sells 1 one-off in-app purchase. Kirin Sudoku asks for nothing beyond the download.
