# Sudoku Now! vs ChainDrop

The clearest difference is iOS requirement: Sudoku Now! at 15.0 against ChainDrop's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sudoku Now! sells 1 one-off in-app purchase and ChainDrop sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
