Q-City: City Builder Sim

- A power grid: coal, wind, solar, nuclear and fusion plants. Electricity flows along roads and buildings

- A water network: water towers, pumping stations and treatment plants. Dense growth needs water

- 18 facilities: police, fire station, elementary school, hospital, university, city hall, parks, plaza, stadium and more

- 6 milestones: every population threshold pays a bonus and unlocks new facilities

- Budget and taxes: set residential, commercial and industrial tax rates separately and read the monthly report

- 12 data overlays: power, water, pollution, land value, crime, traffic, growth potential, and fire / police / health / education / leisure coverage

- Day/night cycle: watch the lights come on at dusk

- Disasters: fires, earthquakes, meteors and tornadoes — trigger them yourself if you dare

- An advisor that flags power shortages, rising crime, unemployment and more

- 3 save slots plus monthly autosave, and JSON export/import to back up a city or move it to another device

PLAYS OFFLINE,

FULLY FREE

- No account, no sign-in

- No server, and no internet needed to play — on a plane or underground

- No in-app purchases — a rewarded ad plays only when you tap for a grant, relief, a doubled reward, or to unlock ×4 speed, the huge map or 6 save slots, and you are asked once more before it starts. An ad may also appear when you open the app, at most 3 times a day (never while you play)

- Your city saves are stored on this device only

HOW TO START

1. Lay roads first (drag)

2. Zone residential, commercial and industrial land within 2 tiles of a road

3. Build a power plant touching a road or zone

4. Put a water tower near your zones

5. As population grows, add police, fire, schools, hospitals and parks to raise approval and land value

Pick a map size (small to huge), a difficulty (easy, normal, hard) and a terrain seed for a different city every time. Available in English, Korean, Japanese, Simplified Chinese and Traditional Chinese.
