An idle merge-miner built on one hard rule: a Digger too weak for the rock in front of it deals exactly zero damage. It prints TOO WEAK on itself and stops, and the pit stops with it, so merging is the only way deeper. Merge Diggers into stronger ones and push down through layers that harden every depth. Halt the descent to farm a layer, or jump back to any depth you reached this run. Every tenth depth from 30 has an Obsidian Boss that pays extra and can drop Geodes. Prestige wipes the run for Geodes, which buy seven permanent upgrades. Free, no IAP at all. Two ads, both opt-in.

Watch a swarm of tiny slammers hurl themselves at a planet and mine it to pieces. SLAM, CRACK, REPEAT.
