About Q-City: City Builder Sim
From a single road to a metropolis. Q-City is a classic isometric city-building simulation. Lay roads, zone residential, commercial and industrial land, hook up a power plant and a water tower, and citizens start moving in and building. As jobs, services and the environment improve, low-rise homes grow into dense high-rises, and your city climbs from Outpost to Village, Town, City, Metropolis and beyond. WHAT YOU GET - Tile-based isometric city building. Pan with one finger, pinch to zoom - Residential (R), Commercial (C) and Industrial (I) zones that grow from density 1 to 3 based on demand and surroundings - 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.
