knocky is a fast single-player destruction game built around simple controls and satisfying tower collapses. Drag to aim, drop the ball, and tear through moving towers before you run out of lives. Each run pushes you to line up better hits, clear tougher layouts, and squeeze more score out of every bounce. Features: - One-touch tower destruction gameplay - Multiple ball types with different weight and bounce - Score-chasing runs with escalating difficulty - Clean visuals and punchy physics feedback - Quick sessions that still reward precision and planning knocky is easy to pick up, but the best runs come from timing, placement, and clean reads on every tower.

Verdict
The clearest difference is in-app purchases: knocky at none against Echo's 1. knocky also leads on ads (none vs shown) and iOS requirement (14.0 vs 17.0). On price, update cadence and device support there is nothing between them.
