Verdict
The clearest difference is price: Slitherlink at Free against Spin Spell's $0.99. Slitherlink also leads on ratings volume (461 vs 14) and rating (4.8 vs 4.6). Spin Spell's advantage is in-app purchases (none vs 10) and chart position (#181 vs unranked). On ads, device support and iOS requirement there is nothing between them.

Slitherlink is free to download; Spin Spell costs $0.99 up front. Slitherlink sells 10 one-off in-app purchases. Spin Spell asks for nothing beyond the download.
Slitherlink holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Slitherlink has 461 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 100% of Spin Spell's written reviews are positive against 89% of Slitherlink's, so the app with the better star average is not the one people write more warmly about.
Spin Spell ships an update every 9 months, Slitherlink every 4 months. Both last shipped on November 1, 2026.
