Introducing "Spiral Excavator Empire" - the ultimate casual idle game where you can build your mining empire from the ground up! Take control of powerful spiral excavators and giant mining machines to unearth valuable ore resources. Dig deep into the earth and extract precious minerals that can be transported to trucks for further processing. Upgrade your excavators to increase their productivity and unlock new levels of efficiency. Each processing facility specializes in a specific type of ore, with up to 10 production lines to manage. Upgrade each facility individually to maximize output. Once processed, the materials are transported by trucks to the harbor and then conveyed onto cargo ships through a network of conveyor belts. Expand your mining operations, optimize your production, and dominate the mining industry. Are you ready to spiral into success?
