Idle Light City

Idle Light City is an idle game about running a lighting factory for an entire city. You start with one factory and a single house that needs light. Produce light bulbs, send them to houses, and earn money. The more buildings you light up, the higher your profit. When a house gets enough light, residents come out and the city looks alive. Lit buildings bring in steady income, even when you are not in the game. Each house has its own number for easier upgrades and management.

How to play?

At the beginning, you only have a factory and one house. Click the buy light bulb button at the bottom of the screen — the bulbs go straight to the house. The top of the house shows how many light bulbs it needs. When the building receives the required number, it lights up and starts generating profit. Click lit houses and upgrade them. This speeds up money generation and increases income per house. The higher the building level, the more it earns. Use the bottom menu to upgrade production: boost light bulb creation speed and other factory stats. When you have enough funds, buy an auto-collector — it automatically collects profits from houses. Next, purchase automatic light bulb buying so production runs on its own and you only handle upgrades. Increase the base speed of light bulbs moving around the city and the chance of producing special bulbs. Keep lighting new houses, watch residents come out, and make Idle Light City brighter with each new light bulb.
