Idle Mining is a free browser-based incremental game where you dig deep underground to discover rare gems and precious minerals. Click or tap the rock face to mine manually, hire workers to mine automatically, and upgrade your tools to dig faster and deeper. The deeper you go, the rarer the resources you'll find -- from common stone near the surface to mythical crystals deep in volcanic layers.
The deepest mine in the world, Mponeng Gold Mine in South Africa, reaches 4 km below the surface at temperatures of 66 degrees Celsius. In Idle Mining, you can go even deeper -- all the way to the Earth's core!
You can mine all the way to the Earth's core at 6,371 meters. Along the way you'll pass through soil, clay, granite, basalt, crystal caves, and volcanic layers. Reaching the core unlocks the Prestige system for permanent multipliers that make each subsequent run faster.
Resources range from common stone (1 coin) to mythical crystal (10,000 coins). As you dig deeper you'll discover copper at 20m, silver at 60m, gold at 120m, rubies at 250m, diamonds at 500m, and mythical crystals at 1,000m. Each resource has unique particle colors and animations.
Yes! Your hired miners continue working while you're away. When you return, you'll receive all the coins your miners earned based on your current miner count and depth. Upgrade your miners before leaving for maximum offline gains.
