Drive a drilling rig deep underground and haul up coal, copper, silver, gold, rubies and diamonds. The catch: gravel and cracked stone are held up by whatever is beneath them. Dig out the wrong tile and the ceiling comes down on your tunnel, or on you. Sell your haul at the surface, upgrade the rig, buy bigger machines, and unlock richer, deadlier dig sites.
