City Strategy Builder Help Guide

City Strategy Builder lets you create step-by-step guides for progressing through your Capital or Allied Culture cities. It includes tools you already use—like the City Planner and Research Calculator—directly inside a single timeline.
Strategies Dashboard

The dashboard is the central place to manage all your saved strategies.

You can create a new strategy by clicking the Create button. You'll name the strategy, choose its type (Capital or Allied Culture), and if it's an allied city, select the associated Wonder. Note: The Wonder selection affects stats and cannot be changed later.

All strategies are stored locally in your browser. The full City Strategy Builder app is only available on larger screens.

Timeline

The Strategy Builder is organized as a timeline: a sequence of steps that represent how your city evolves over time.

Open the timeline by clicking view_timeline in the right-side menu.

Timeline Item Types

Each step in the timeline is a timeline item. There are three types:

  • Description — free-form notes for the step (any text you want).
  • Research — a built-in Research Calculator. Pick target technologies and it shows the required cost.
  • Layout — stores the city layout for the step. When selected, it opens the layout in the built-in City Planner.
Creating New Timeline Items

Every new strategy is created with three timeline items by default (Description, Research, Layout).

To insert a new item, click the add button add_box shown between existing items. The new item is created exactly at that position in the timeline.

Editing and Deleting Items
  • Rename: each item has a title. Click edit to edit it.
  • Delete: click delete to remove the timeline item.
How Research Items Work

Research items follow special rules. The whole timeline shares a single research tree and tracks what is already opened.

Each research item automatically treats all technologies selected in the research items above it as already opened. That means you can’t change previously opened technologies in later research steps.

Example:

  • You create the first research item and pick technology A.
  • You create the second research item. Technology A is already opened there.
  • In the second item you pick technologies B and C.
  • Later you go back to the first research item and also pick B. When you open the second item again, A and B are now marked as opened, and the only picked technology remaining for that item is C.
How Layout Items Work

Unlike research items, layout items are independent. Editing one layout does not update any other layout item.

The only time another layout affects a layout item is during creation:

  • When you create a new layout item, it copies the layout from its first ancestor layout item (if one exists).
  • If there is no ancestor layout, a default layout for the selected city is created.

Check City Planner Help Guide for more details.

Creating Layout Items: Layout vs Import Layout

There are two ways to create a layout item:

  • Layout — creates a new layout by copying the closest ancestor layout (or default layout if none exists).
  • Import Layout — imports a layout from the City Planner. To import, you must have a matching layout saved in City Planner for the same city and world wonder as the current strategy.
Strategy Builder vs City Planner

Strategy Builder covers most city planning use-cases directly in the timeline. However, City Planner includes extra tools that are not available inside Strategy Builder (for example: Inventory and City Snapshots).

If you need those tools, plan the layout in City Planner first, then import it into the Strategy Builder.

Saving

Strategy Builder has auto-saving, but it’s still a good idea to click save Save periodically—especially before navigating away from the builder.
