Deep Core Idle: Mining Tycoon

Grab the crank, fire up the boilers and drill all the way to the heart of the planet!

Deep Core Idle is a relaxing idle clicker and mining tycoon game set in a steampunk world. Tap to dig, upgrade your miner and watch the gold roll in, even while you're offline.

⚙️ BUILD A STEAMPUNK MINING RIG
Start with a rusty hand crank and grow it into a colossal golden steam giant. Add steam boilers, piston hammers, Tesla coils, fire furnaces, clockwork tunnelers and magma pumps. Every new machine visibly evolves your drill through 5 tiers.

⛏️ DIG THROUGH 10 LAYERS
Break through topsoil, clay, fossil limestone, granite, basalt columns and glittering obsidian, then push into the upper and lower mantle, the swirling outer core and the blazing inner core. Every layer has its own look, from roots and fossils to molten rock.

🚃 RUN YOUR MINING EMPIRE
Mine carts haul gold along the rails to the lift, and your income climbs with every upgrade. Buy machines one at a time or in bulk (x10, x100, max) and reach milestones that double their output.

💎 PRESTIGE WITH CORE CRYSTALS
Dig a new shaft to earn Core Crystals. Every crystal permanently boosts all your gold, so each run goes deeper and faster. A classic incremental loop that keeps paying off.

💤 IDLE EARNINGS WHILE YOU'RE AWAY
Your drill keeps digging when you close the game. Come back to a pile of gold, ready for the next upgrade.

🎁 DAILY REWARDS
Come back every day for a growing 7-day reward calendar, with Core Crystals on day 7. Miss a day and it waits for you.
