Two tools every builder needs
Tips
The game highlights two tools through its badges: wiring and property configuration. Using the wiring tool to connect objects earns you the Electrician badge, and configuring an object's properties earns the Engineer badge.
- The wiring tool links objects together so they can trigger or respond to each other.
- The configure tool lets you change individual properties on any object, giving you fine control over how it looks and behaves.

Co-op building and private servers
Check
Team building lets multiple players work on the same plot at once. If you want a controlled group, a free private server keeps the session limited to people you invite.
- Up to nine players can be in one room at a time.
- Open a private server if you want to build only with people you know it costs nothing.
Playing on mobile vs. PC
