The game is viewed through side-on underground sections and management screens. The main objective is to establish mining sites, extract valuable materials, and earn enough money to expand the operation while keeping workers supplied and productive.

Players select workers, direct excavation, place or operate equipment, and move resources through the mine. Progress comes from finding better deposits, improving facilities, and managing the workforce across increasingly difficult locations.

Begin with a compact mining layout and avoid spending all available cash on equipment. Establish a reliable supply of basic materials before expanding into deeper or more hazardous areas.

Keep workers assigned to useful tasks, monitor production and expenses, and improve transport and processing capacity when bottlenecks appear. Exploration is valuable, but an unprofitable mine can consume resources quickly.
