Mini City Tycoon Codes (July 2026)

Mini City Tycoon is a Roblox town-builder where you design a miniature city from scratch — laying roads, placing residences, hospitals, schools, and commercial buildings across different maps. Diamonds are the currency that fuels your expansion, letting you unlock new building types as you level up. Codes are the quickest way to earn them without waiting.

Where New Mini City Tycoon Codes Are Released

Aurion Games, the developer of Mini City Tycoon, tends to release new codes around major game updates, milestone events such as visit or like counts, and occasionally as compensation after server outages or notable bugs. There is no fixed schedule, so codes can arrive without much warning.

The Aurion Games Discord server and the Aurion Games Roblox group are the two primary places where new codes are announced first. Bookmark this page as well — the list above is checked and refreshed as soon as new codes surface.
