🏗️💡Citybuilder: Springfield 08/26 Walkthroughℹ️🏗️

Let’s Build and Grow Your City!

In this event, your goal is to place buildings and assign jobs to construct them. Every completed residential building increases your Development Index, which represents your overall progress in the event.

  • The Development Index measures your overall progress in the event. You can think of it as your event XP.

  • You develop a separate event city on its own dedicated map, independent from your main story city.

  • To reach the end of the Event Pass and claim the final reward, you need to reach 9,000 Development Index.

Let's start!

First, you need to build the first residential building. Placing buildings is free.

Tap anywhere, then place the building.

KEEP IN MIND

Don't forget that every building needs to be connected to the road.

To construct the building, you need to deliver materials to its construction site.

Next, let’s build a service building. If you build it near a residential building, the residential building will provide extra Development Index.

Complete additional cargo jobs to upgrade service buildings.

Residential buildings are the main source of increasing your Development Index.

Service buildings act as boosters for your existing Residential buildings. When placed nearby, they directly upgrade them, allowing those Residential buildings to generate more Development Index.

Another building type is Monuments. Monuments also increase your Development Index and, just like Residential buildings, they can be upgraded by nearby Service buildings.

KEEP IN MIND

Make sure that the low level residential building that have already been maxed are not surrounded by too many service buildings. This results in wasted aura of the service buildings that can be used for boosting other residential buildings with higher levels

Development Index

Development Index is a measure of your overall event progress.

As your Development Index increases, you will:

  • Unlock new buildings to construct

  • Progress through the event pass

  • Unlock additional passenger jobs

The higher your Development Index, the more content becomes available, allowing you to continue progressing through the event. It's the key metric to watch, measuring how well your city is developed.

Check the boost on the Residential Buildings

Each residential building has a maximum Development Index value it can reach.
You can tap a residential building and check the circled progress bar to see how close it is to its maximum:

  • Building not fully maximized:

  • Building at maximum:


If a building is not maxed out yet, try adjusting nearby service buildings.

In this event, buildings can't be stored. If you run out of space, try upgrading your current buildings to the maximum and boost the development index. As you progress in the event, you'll unlock the next expansion, allowing you to add more buildings.
If you do not have enough space, remove a few roads for a moment.

  • Rearrange the buildings.

  • Put residential buildings closer to service buildings.

New additions to this event

Bigger, Denser City Map

  • There are more buildings to construct than ever before! Between milestone unlocks and gem buildings, you can now build across virtually the entire city area.
    Streamlined Milestones: You will unlock 3 Residential buildings per milestone, with job requirements scaling naturally (1, 2, and 3 jobs) as your city grows.

Service Buildings & Expanded Reach

  • Larger Boost Areas: All Service buildings now boast a larger aura, making it easier to cover more neighborhood blocks and maximize your city's boost.

  • Badge Train Contracts: Service buildings are now unlocked exclusively through specialized Event Badge Train jobs.

Unique Gem Buildings

  • Available Earlier: Premium gem buildings can now be unlocked earlier in the event to help boost your city’s growth right from the start.

  • Fresh New Look: Gem buildings feature brand-new visual designs, clearly distinct from the standard trainyard buildings purchasable with Event Coins.

Smoother Progression & Endgame Goals

  • Monument Infinite Jobs: Once built, your Monument will generate an endless recurring job linked directly to it—ensuring you always have contracts to run and never get stuck!

This event is all about combining creativity, strategy, and trains into one brand-new experience.
Every city will look different, and every Dispatcher will build their own unique story on the rails.
We hope you'll enjoy it!
