Build your next upgrade.

New facilities start with four equipped Standard Utility Racks. Buy more for 100 coins each, then install them in any unlocked room. Each rack holds four miners.

Purchased cells are stored in Inventory until you use them. Activity rewards can fill storage to 48 hours; activated cells can take it above 48 hours.

These miners are bought through crypto checkout, do not use coins, and are not upgradeable. They stack with your regular miners and active mining energy.
