Tile Info

Feedback

Share bugs, ideas, or balance notes. The form opens in a new tab (Nextcloud). You can paste the build info below into the form if it asks.

Playthrough recording

Record a timeline of building attempts, undo, city measurements and issue notes. This is a diagnostic log, not a video or an exact replay. Recording starts only when you choose it.

Includes the game build, map seed, addons, tile coordinates and finances. Account details, chat, passwords and raw keyboard input are excluded. Your draft is saved in this browser about every two seconds; nothing is uploaded automatically.

Recording is off.

    Inspect recorded moments and measurements. This is a diagnostic timeline, not a simulation replay. Opening a file leaves your city and recording draft intact.

    Costs

    Operating balance: $0/mo
    After material imports: $0

    Estimate uses current buildings and the latest month's imports. Construction material purchases vary as your city grows. Direct build prices are paid immediately from your cash and are separate from this monthly budget.

    Higher taxes raise revenue but reduce happiness and slow growth. Lower taxes give up to +10 happiness points. Happiness updates each month; the income estimate uses the latest happiness report.

    Debt: $0

    Help

    A lightweight reference for the current build. This is meant to be a quick in-game manual while balancing and systems are still changing.

    Quick Start

    • On the region screen, adjust generator settings if you want, then Generate and click a cell.
    • Use Found City to start a new settlement, then begin with roads, a few zones, and power.
    • Watch food, utilities, and budget early. The tutorial cards and Trade / Population panels help explain shortfalls.

    Controls

    • 1 / 2 / 3 / 4: pause, slow, medium, fast simulation speed.
    • Space: toggle pause.
    • Q / E: rotate around the center of your current view. R: rotate the selected building when supported.
    • City / Map beside the minimap: frame your roads and buildings on all levels, or show the whole site. City shows the map when nothing has been built.
    • Right or middle mouse drag: pan the camera. Mouse wheel: zoom.
    • Esc: clear overlays, close the build flyout, and deselect the current tool.

    Overlays And Panels

    • Shift+P / W / T / H / U / F / Y: power, water, traffic, happiness, underground, fire, and police overlays when available.
    • Budget: city income, maintenance, debt, taxes, and service costs.
    • Trade: commodities, imports, freight, workforce, and economy tips.
    • Population Overview: residents, jobs, workers, food demand/capacity, and traffic.
    • News: click the ticker to open history.

    Tutorial

    Clears "Got it" / "Remind later" on every hint for this save and turns the tutorial back on if it was disabled.

    Troubleshooting

    • Zone planning: select a zone to compare capacity by development level and growth materials before placing it. The card can be collapsed while building.
    • First development: Inspect shows progress for vacant zones. Each eligible month adds progress, and a successful growth check can start development sooner. Blocked months pause progress; required materials still need to arrive.
    • Zones not growing: inspect them for power, water, road access, food, or materials.
    • Revenue feels low: check Trade for imports and Budget for upkeep.
    • Food shortage: open Population Overview and Trade, then add farms, imports, or neighbor supply.
    • Power / water issues: use overlays to see where service stops.
