In PowerPlay, players manage a futuristic power grid and supply a growing number of industrial and residential areas with varying energy needs. Power plants and power lines come in different types with their own construction requirements. This calls for strategic planning. Limited space and rising electricity demand drive the need for restructuring the existing power grid. Developed over three days at the H-BRS GameJam 2025 by a team of five. Partially inspired by Mini Motorways. PowerPlay is playable but not yet a fully-fledged game.
