Verdict

The call

The clearest difference is rating: Slitherlink at 4.8 against Loop Loop Puzzle's 4.4. Slitherlink also leads on ratings volume (457 vs 13). Loop Loop Puzzle's advantage is update cadence (every 2 months vs every 4 months) and review sentiment (100% vs 89%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Slitherlink holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Slitherlink has 457 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 89% of Slitherlink's written reviews are positive against 100% of Loop Loop Puzzle'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, Loop Loop Puzzle every 2 months. The most recent releases landed on September 27, 2026 and June 20, 2026 respectively.
