Your city saves automatically.
Six challenges with a goal and a deadline. Win, and the city is yours to keep.
POLIS (πόλις) is the ancient Greek word for city: a place and the community that lives there. Build yours in your browser, and explore the same city in 2D or 3D.
Build a neighborhood. Connect roads, power and water, then zone homes, shops and industry. Buildings develop as demand, land value, education and local services allow. Existing plants, pumps and water towers can be upgraded for more capacity, with higher upkeep.
Keep the city working. Open City budget from the Treasury to manage taxes, service funding, infrastructure renewal, ordinances and loans. Businesses need workers and customers; old infrastructure needs care. Watch monthly costs, reserves and the outlook before expanding.
Read the map. Overlays reveal coverage gaps, pollution and congestion. Avenues, buses and elevated rail help the transport network. Moving cars and people bring the city to life; individual vehicles are a visual layer, not a simulation of every resident.
Make it yours. Choose a difficulty or scenario, switch views, and explore optional music, seasons and day–night settings. Power saver is on by default. Cities save in this browser; export a save code to back them up or move them to another device.
Open saved cities from either version. Each version keeps its own progress.
Give your settlement a new name.
Pan: left-drag with Pan or a single-building tool selected, or hold Space while dragging with any tool. Hold the arrow keys to move the map faster. Zoom: scroll, or use + / −.
Rotate & tilt: right-drag, or hold Shift while dragging. With a single-building tool selected, left-drag pans and a left click places the building. Move sideways to rotate; move up or down to tilt.
Drag with one finger to pan. Pinch to zoom and twist two fingers to rotate.
Slide two fingers up or down together, keeping their spacing steady, to tilt.
Use the 2D / 3D button to switch views. Entering 3D starts at the matching 2D angle; you can then tilt freely.
With a tool selected, click and drag to draw roads and zones immediately. Hold Space and drag to pan, or use the arrow keys. Click to place individual buildings.
On touch screens, tap to place, drag to pan, or hold briefly, then drag to draw roads and zones.
In Pan mode, select a building to inspect it. Supported buildings offer rotation controls in their info card.
Roads carry power and water — every building just needs to touch a connected road.
Narrow roads jam easily; upgrade busy stretches to avenues or add bus stops nearby.
Businesses need an educated workforce to reach level 3 — build schools near homes.
Crime grows with density and erodes land value; police coverage suppresses it.
Click the Treasury to open City budget: taxes, service funding, infrastructure renewal and loans. Drag panels by their title to rearrange.

Each map has its own river and forests. Pick one, or roll new lands.
Manage your monthly balance, services and borrowing.
Estimates paid in three instalments. Updates as the city changes.
Outlook holds the city and settings fixed; includes business adjustment and renewal. Growth, disasters and future projects can change it.
Businesses are adjusting to workers and customers. Current revenue may not last; use the outlook when planning spending.
Service funding changes coverage and cost. Renewal pays for ongoing repairs and replacement; 100% maintains a stable average infrastructure age.
Loan repayments are included in your monthly balance.
