Verdict

The call

The clearest difference is ads: Slitherlink at none against Snake.io's shown. Slitherlink also leads on review sentiment (89% vs 70%) and rating (4.8 vs 4.6). Snake.io's advantage is update cadence (every 2 weeks vs every 4 months) and ratings volume (480K vs 461). On price, in-app purchases, monetization model and device support there is nothing between them.
