🔨 Build & Read the Grid

To build: pick a source by pressing its number key or clicking it in the build guide on the right, then click open ground near homes. The green lines show which homes it reaches. Press Esc or right-click to return to inspecting. Space pauses the clock; building does not.

To read it: the bottom strip is your control room. In 📅 TODAY, keep the colored mountain (the power you are making) above the white line (what the town needs). A red gap means homes go dark, especially at the 19:00 dinner rush. 💰 MONEY shows your net income per second; when it turns red, costs are outrunning income.

Demand keeps rising as the town grows. A grid that is enough today will not be enough next week.

🏆 How to Win & Lose

How to win: reach a ⭐ Sustainable City by running the town entirely on clean power. Hold all of the following for 90 seconds:

• 50 homes powered
• no homes going dark: the grid keeps up all night
• no gas burning: sun, wind, nuclear, and batteries only
• enough always-on backup for the peak: nuclear, batteries, or a gas reserve for a windless night

How to lose: if pollution reaches the cap, the game ends. Gas is cheap and runs at any hour, but it pollutes, so do not lean on it too hard. The game also ends if your balance stays negative. Every plant costs upkeep for as long as it stands, so an overbuilt grid drains cash even when idle.
