Why codes might not work
- The code has expired and is no longer accepted in Mini City Tycoon.
- There is a typo, missing character, or extra space; codes are case-sensitive and must match exactly.
- The code was already redeemed on your Roblox account, so it cannot be used again.
- The game session is out of date or lagging; restarting Mini City Tycoon or Roblox can refresh code status.
Where to find more codes
New Mini City Tycoon codes are usually shared around community milestones and update announcements. For the latest official news and giveaways, keep an eye on the developer’s Aurion Games Roblox group and the official Aurion Games Discord server. Bookmark this page — code lists are refreshed regularly with any new additions.
Mini City Tycoon codes are free, time-limited bonuses and must be entered exactly as written; avoid any third-party “code generator” sites or tools, as they cannot create real codes and may put your account or personal data at risk.
