Verdict
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).

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 Loop Loop Puzzle sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
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.
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.
