What These Updates Cover

Each note is written to explain the player-facing result first, then the design or technical reason behind it. This keeps the update history useful for returning mayors, new players, and search crawlers reading the site without launching the game.

City Systems

Road access, utility coverage, zoning behavior, taxes, happiness, public services, and the rules that shape city growth.

Performance Work

Model loading, render cost, cache behavior, and mobile-friendly changes that keep the city playable on modest devices.

Player Guidance

Short explanations of how each change affects city planning, budgets, service placement, and early-game decisions.

Community Feedback

Comment threads collect bug reports, balance reactions, and requests so follow-up work can be tied to a specific version.

How To Read A BuildCity Patch Note

The update log is organized around practical questions a player would ask after returning to a saved city.

Check the gameplay impact

Look for changes to money flow, service coverage, roads, zoning, happiness, and city rank before changing a long-running layout.

Review stability notes

Performance, loading, cache, and save-state fixes are called out because they affect browser memory, network requests, and older devices.

Use comments for follow-up

If an update changes your city in an unexpected way, leave feedback on that version so the report includes the right context.

Version v1.4.48

Added the 112×112 Grand Canyon map. Build on broad plateaus above a narrow, deep dry canyon, surrounded by red sandstone cliffs and layers of distant mountains and valleys. This inland map has no rivers or sea.
Unlock Grand Canyon once per account for 500 gems and reuse it when creating new cities on that account without paying for the map again.
Dragging roads one or two cells wide between flat ground on opposite sides of the canyon automatically builds steel arch truss bridges. Built bridges can be saved, reloaded, and demolished.
Grand Canyon is now available in the map shop and city creation screen, with terrain previews, actual coal, ore, and oil distribution, and deposit gauges for the new map.
