About game
Manage your own energy network by placing power plants to feed growing urban centers. You start by setting up simple windmills and solar panels before scaling up to massive nuclear reactors. Every city builder strategy relies on balancing supply with demand to maximize cash flow. Watching your power plant grid hum with activity brings a satisfying sense of progress as your bank balance climbs. Offline energy production ensures your empire continues earning coins even when you step away from the keyboard. Global upgrades allow you to boost station output or squeeze more profit out of every neighborhood. Expanding your island territory gives you the extra space needed for bigger infrastructure projects. Jump into this idle simulation for free right now in your browser with zero downloads required.
