About Idle City

Idle City is a relaxed simulation game about building up and managing something over time. Grow a city from a handful of buildings into a sprawling skyline, even while you're away.

How to Play

Tap to construct and upgrade buildings; income keeps growing over time, so check back to reinvest.

Tips for Idle City

  • Upgrade the buildings that earn the most per second first.
  • Check back regularly to reinvest income rather than letting it sit.
  • Unlocking new building types usually pays off faster than over-upgrading old ones.
