# Flipbook vs 数独大师

The clearest difference is iOS requirement: 数独大师 at 15.6 against Flipbook's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Flipbook sells 7 in-app purchases, starting at $1.99 per month and 数独大师 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
