Deep Dig Idle is a relaxing incremental game about digging a very deep hole. Tap the rock face to dig, and sell the ore you bring up to buy a sharper pickaxe, hire miners and fit a drill. The deeper you go, the harder the rock — but the more valuable the ore, from stone and copper to silver, gold and gems in the magma rock near the core. Your miners keep digging when you close the game (at half speed, for as long as your lantern lasts), and your progress is saved on this device. Reach the core at 1,000 metres to earn crystals, then start a new dig with a permanent bonus.
How to play Deep Dig Idle
Goal: Reach the planet’s core at 1,000 metres, then dig again with crystals for a bigger bonus.

Rules
- Every tap does digging work: it takes you deeper and brings up ore that is sold automatically.
- Miners dig on their own; a drill makes them faster.
- Deeper layers have harder rock but much more valuable ore.
- When you come back, your miners will have kept working at half speed for up to your lantern’s hours.
- At the core you earn crystals: each one adds 25% to the value of all ore in later digs.
Tips and strategy
- Early on, a better pickaxe pays for itself fastest; then hire miners.
- Buy a lantern before you leave for a long break.
- Your progress is saved automatically on this device only.
