# Impossible 7! vs f.u.n.

The clearest difference is rating: f.u.n. at 4.5 against Impossible 7!'s 4.1. f.u.n. also leads on update cadence (every 10 months vs every 63 months). Impossible 7!'s advantage is ratings volume (48 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
