# Sudoku.com vs kerf

The clearest difference is ads: kerf at none against Sudoku.com's shown. Sudoku.com's advantage is chart position (#6 vs unranked) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

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