About this game
Dig deeper. Smelt more. Expand the network. The mine must grow.
Idle Deepcore is an incremental mining game where every block you break brings you closer to an underground industrial empire. Start with your mouse. End up leading a network of automated mines plunging into the depths.
From a pickaxe to an empire
Break your first blocks by hand. Extract raw ore. Smelt it into ingots. Reinvest. Then start again, bigger, deeper, faster.
What begins as a simple excavation becomes a network of mines running in parallel, while you are already planning the next one.
Conquer the world map
Claim new mining zones, each with its own terrain and potential. Manage multiple mines in parallel. Decide where to invest for the best long-term return.
The cycle: mine, smelt, upgrade, repeat
Ore alone is not enough. Turn your raw materials into valuable ingots at the smeltery. Unlock upgrades, buy more powerful furnaces, develop advanced mining technologies.
Every layer of progression feeds the next.
