Idle Grid

Idle Grid is an idle factory-building game where you design and expand an industrial network on a grid. Place factories, power plants and research facilities, then optimize their positions and upgrades to grow your income, including while you are away.

Build on the grid

Building placement affects efficiency through adjacency bonuses. Put factories next to power plants, group research facilities to boost production, and use compactors to multiply factory output. Warehouses increase storage capacity, while power plants keep the grid running.

Manage power and upgrades

Balance power production with consumption, build backup storage for emergencies, and manage brownouts and blackouts. You can upgrade power plants as demand grows. Each building type has three upgrade tiers, and research facilities provide stackable income bonuses.

Upgrade individual buildings, raise a building to its maximum level, or upgrade all buildings of the same type at once. You can focus your strategy on factory output, research efficiency or power generation.

Buildings

• Factories generate your primary income.
• Power plants supply the grid.
• Research labs boost factory efficiency.
• Warehouses expand storage capacity.
• Compactors multiply factory output.

The game also includes auto-save, save-file export and import, zoom and pan controls, keyboard shortcuts and visual feedback for actions.
