Idle City Gameplay Guide

Building Types

Residential buildings generate steady income. Commercial buildings boost nearby residential income. Industrial buildings produce bulk resources at intervals. We found that clustering commercial buildings near residential zones creates the highest passive income per grid space.

Idle Progression

The idle mechanic means your city earns resources while you're away. Coming back after a few hours to find a pile of accumulated wealth is genuinely satisfying. Longer absences produce bigger returns, incentivising strategic planning before you leave.

Tips and Strategies for Idle City

• Cluster complementary buildings — Place commercial next to residential for income bonuses.
• Upgrade before expanding — Upgraded buildings produce more per square than new basic ones.
• Check back regularly — Collect accumulated idle income to reinvest in growth.
• Plan your grid layout — Efficient layouts compound wealth faster than random placement.
