Echo Diver

Guide a tiny ivory submarine through 24 hand-crafted deep-sea mazes. Every swipe sends the diver forward until rock, coral, a closed gate, or another obstacle brings it to a stop. Each stop releases a bright visual sonar ring that exposes nearby danger. Read shifting currents, collect oxygen pearls in the correct order, predict turn-based gates, and stay clear when echoes of your earlier routes return through the trench. As dives grow deeper, pressure closes the visible safe channel. Plan complete lines instead of single steps, watch every visual warning, and reach the beacon before the route disappears. Echo Diver is fully playable without advertising. The optional SONAR MAP AD reward reveals the complete hazard layout once before the next dive, and never skips a level or removes a failure.
