Verdict

The call

The clearest difference is ratings volume: Slitherlink at 457 against Slitherlink Puzzles's 3. Slitherlink also leads on review sentiment (89% vs 75%). Slitherlink Puzzles's advantage is update cadence (every 6 weeks vs every 4 months) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Slitherlink sells 13 one-off in-app purchases and Slitherlink Puzzles sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Slitherlink Puzzles holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Slitherlink has 457 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 89% of Slitherlink's written reviews are positive against 75% of Slitherlink Puzzles's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Slitherlink ships an update every 4 months, Slitherlink Puzzles every 6 weeks. The most recent releases landed on October 15, 2026 and October 2, 2026 respectively.
