An enormous mountain of sand. Natural gold hidden somewhere inside. Start with simple tools, turn your first loads into income, and build a factory that helps you search.

Start with a scoop

Dig into the slope, fill your shovel and carry your first loads. Sell the sand, upgrade your tools and make the next trip count.

Let machines take over

Put mechanical arms to work beside the pile. Watch them collect sand and feed it onto conveyors while you plan the next part of your factory.

Keep it moving

Connect machines with conveyors, split the flow and bring routes back together. A useful junction or a better connection can keep the whole line moving.

Make more from your sand

Feed your sand into processing machines and turn it into products worth selling. Build around each machine’s inputs and outputs, then reinvest the proceeds in your next upgrade.

Choose your next upgrade

Improve your tools, unlock machinery and develop the parts of your factory that matter to you. Keep digging, keep expanding, and keep searching for the natural gold hidden in the mountain.
