# LOOP vs Slitherlink

The clearest difference is update cadence: LOOP at every 3 weeks against Slitherlink's every 6 weeks. Slitherlink's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

LOOP ships an update every 3 weeks, Slitherlink every 6 weeks. Both last shipped on October 24, 2026.
