When Do New Mini City Tycoon Codes Drop?
The Mini City Tycoon dev drops codes at visit milestones (100M for 100 Diamonds as a 100 million visit reward, 200k for 100 Diamonds as a like-milestone drop), version updates (UPDATE for 30 Diamonds), and starter or hidden drops (FIRST for 50 Diamonds as a launch-period drop, secret for 25 Diamonds as a hidden promo).
🎮 About Mini City Tycoon
Mini City Tycoon is a Roblox city-building tycoon where you place mini buildings on your plot, earn Cash from passive income lines, and stack Diamonds to roll for premium structures and themes.
100M and 200k each drop 100 Diamonds (the biggest stacker), FIRST drops 50 Diamonds, UPDATE drops 30 Diamonds, and secret drops 25 Diamonds.
Diamonds are the premium tycoon currency, so stacking all five codes on a fresh account gives a fresh city plot a solid starting bankroll for rare building unlocks.
One older code (BUG) has rotated to the expired list from an earlier bug-fix compensation drop.
All codes in this list are case-sensitive and released by the developers of the game. Codes can expire without warning; if one shows invalid, it was already rotated out.
