# Sudoku World vs Oretrace

The clearest difference is ads: Oretrace at none against Sudoku World's shown. Sudoku World's advantage is device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Sudoku World sells 1 one-off in-app purchase and Oretrace sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
