Idle Mining Empire is a business game about running a mine. You start with a single shaft and a few miners, and step by step you build it up into a profitable mining empire. It is relaxing to play, because much of the work keeps going even when you are not tapping.
Every mine works as a chain of three steps. First, tap your miners to start digging ore at the bottom of the shaft. Next, the elevator carries the ore up to ground level. Finally, the ore is transported to your warehouse, where it is sold for profit. Hire a manager at each stop and that step runs automatically. Spend your coins to unlock new mine shafts, upgrade each part of the chain and activate power-ups that speed everything up.
