SimCity BuildIt Layout Guide – 3 Million Population!

SimCity BuildIt Layout Guide – 3 Million Population!

Hey Everyone!

8 April 2015 – Updated to 2.3.2

After the launch of Tokyo Town a couple weeks back, we now have a SimCity BuildIt layout guide to go with the new Tokyo Town Zones – and boy, this one is huge. The new population based on the simulation is just a hair under 3 million at:

2,940,454 Sims

BIG BIG BIG thanks to Zegerman for continuing to experiment and update their guide.

This is a constantly evolving number as we experiment with the layout. DO NOT take this population figure as the HIGHEST number possible. If you have a suggestion to improve (with NO HACKS) please let us know!

We figured since many may be working on the previous version of the 2.5 million guide, we thought it best to leave the old post intact and instead create a new post based on the new Tokyo Town buildings. You can view the old guide here.

Utility Services

Now because of the increased service requirements TT zones need to function, we had to increase the amount of utility buildings so that does reduce the amount of residential zones (but not # of residents!)

This layout uses the highest tier available for utility services (more in-depth info here).

Utility Buildings Quantity
Power Fusion 7
Water Water Pumping Station 10
Sewage Deluxe Sewage Treatment Plant 10
Waste Recycling Center 8

Coverage Services

This guide uses the highest (T3) coverage services to provide fire, police and health to Sims (in-depth info here).

Service Buildings Quantity
Fire Deluxe Fire Station 4
Police Police Precinct 4
Health Hospital 6


Parks, Education and transportation can EACH provide coverage area to reach 100% population boosts to all residential areas. This means maximizing each of the three specialization and overlapping their coverage areas provides 300% total boost (in-depth info here).

Specialization (Each: 100% | Combined 300%) Buildings Quantity
Parks Sculpture Garden 95
Education University 8
Transportation Helipad 21

Gambling, Entertainment, Landmarks COMBINED can provide a coverage area to reach 100% population. Unlike the specializations above, you can reach a MAX of 100% using any combination of the three. Gambling is used because it is the cheapest specialization to provide 100% coverage (20 keys). Landmarks are used because they provide a larger coverage area (its a balancing act between the two). Entertainment buildings have a massive building size so they take up space that could provide more residential zones.

Specialization (Each: Variable | Combined: 100%) Buildings Quantity
Gambling Luxury Casino 20
Entertainment None Used
Landmarks Washington Monument 1

This means you can have a maximum of 400% population boost based on specializations.

NOTE: (many have asked about why we use Luxurious Casino versus Luxurious Casino Tower): The maximum amount of boost you can receive from a specialization is 100%. Overlapping two of the Luxurious Casino Tower (which give 60% boost each) would result in a 120% boost (20% wasted). So stick with the Luxurious Casino and you can save the golden keys.
