Mini City Tycoon is a Roblox city-building game where you lay out roads, place homes and public services, and steadily grow a small settlement into a full metropolis. Diamonds are a key currency for unlocking new structures and expanding your city, and codes are the quickest way to earn them without spending a thing.

How to Redeem Codes in Mini City Tycoon

How to redeem Mini City Tycoon codes
Launch Mini City Tycoon in Roblox on your device.
Press the Settings button — the cogwheel icon — located on the right side of the screen.
Inside the Settings menu, click the Codes button.
Type a code into the text box. Codes are case-sensitive, so copying and pasting directly from the list above is the safest approach.
Press the green checkmark button to submit. A confirmation message will appear on screen, and your Diamonds will be credited immediately. If a code is no longer valid, an “Invalid Code” message appears instead.
