# Slitherlink vs Tetrasquare2

The clearest difference is rating: Slitherlink at 4.8 against Tetrasquare2's 3.0. Slitherlink also leads on ads (none vs shown) and ratings volume (461 vs 1). Tetrasquare2's advantage is update cadence (every 2 weeks vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.
