# 摩天轮 vs 数独杀

The clearest difference is rating: 数独杀 at 5.0 against 摩天轮's 2.9. 数独杀 also leads on update cadence (every 3 days vs weekly). 摩天轮's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. 数独杀 sells 1 one-off in-app purchase. 摩天轮 asks for nothing beyond the download.
