How it works

Three plans make a town

You build in the same order a real town grows: the ground first, then the streets, then the homes.

Plan A · Ground

Shape the land

Raise hills, carve valleys and smooth the slopes, then paint the ground with grass, sand and stone.

  • Sculpt
  • Paint
  • Water
Plan B · Streets

Connect the streets

Draw roads that follow your hills, join them at junctions, and add rivers and ponds along the way.

  • Roads
  • Junctions
  • Paths
Plan C · Lots

Move the neighbours in

Mark out lots, set each one's venue, dress the streets with trees and lamps, and pick the time of day.

  • Lots
  • Objects
  • Lighting
