About

Echo Dig

Read full description

The mine below owes nobody anything. The only way out is down. ECHO DIG is an endless arcade digger set in a mine that's pitch black. Your headlamp reaches a few feet, and the only map is the sonar echo you fire into the dark. Every ping reveals gems, tunnels, lava... and tells whatever lives down there exactly where you are. DIG BY FEEL, SURVIVE BY EAR - One-thumb controls: drag to steer, pull down to gun the drill - Tap with a second finger to fire an echo. Light up the dark, mark the gems, find the safe path - Blast charges punch through rock and lava when steering isn't enough - Grab the overcharge star and nothing can touch you. Briefly. THE DEEPER, THE STRANGER - Four zones, each with its own rules: Topsoil, Magma Core, Crystal Caverns, and The Abyss - World events flip the game mid-run. A Gem Rush floods the walls with treasure while the ceiling comes down; a Blackout kills your lamp and leaves you navigating by echo alone - Something down there hunts by sound. Every ping is a choice: see more, or stay unheard - Hand-placed discoveries in the deep: an abandoned drill, fossil bones, a cable that descends farther than it should... - And beneath The Abyss... The Sunken Sea: an underground ocean where oxygen is life, currents own the water, and your echo cuts through the silt FAIR, NOT SOFT Every death has one cause and it's usually your greed. No cheap kills, no unwinnable rooms. Just rocks, lava, falling debris, and decisions you'll swear you'd make differently. Then you press DIG AGAIN. FOR THE FAMILY Joe isn't digging for glory. Every gem is a debt payment, a roof patch, a meal. How deep would you go? FREE TO PLAY, HONESTLY Every new player gets the COMPLETE game (The Abyss, Zen Mode, all of it) free for their first 5 days. After that, the mine is free to 240 meters, with no ads, no energy timers, no nagging. One single purchase opens the sealed hatch forever. No subscriptions. Ever. - Quick runs: a full dive takes a couple of minutes - Works in silent mode, pauses for calls, saves your best depth - iPhone and iPad The mine is dark. The debt is due. Descend.

Verdict

The call

The clearest difference is in-app purchases: Shadow Ninja at none against Echo Dig's 1. Shadow Ninja also leads on update cadence (every 8 days vs every 3 weeks). Echo Dig's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
