# Slitherlink vs DNA Mutations Puzzles

The clearest difference is rating: Slitherlink at 4.8 against DNA Mutations Puzzles's 3.0. Slitherlink also leads on review sentiment (89% vs 50%) and ads (none vs shown). DNA Mutations Puzzles's advantage is update cadence (every 3 weeks vs every 4 months) and iOS requirement (8.0 vs 15.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Slitherlink sells 13 one-off in-app purchases and DNA Mutations Puzzles sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
