Building a strong roster of Uma trainees in Uma Tower Defense gets a lot easier with free codes. Redeeming them adds Carats, Monies, and even rare units to your account without any extra grinding.
Working Uma Tower Defense codes
Six codes are currently redeemable, together worth thousands of Carats, tens of thousands of Monies, and a couple of free units.

1000TRAINERS is the strongest code on the list right now, handing over a Special Dreamer unit alongside a large Carats and Monies bundle. Redeem it before you spend on the gacha shop so those Carats stretch further.
How to redeem codes in Uma Tower Defense
Codes are entered through the in-game shop menu, not a separate website. Follow these steps on any device running Roblox.
Enter codes exactly as shown, including capitalization, since the redemption box treats mismatched entries as invalid.

Where new codes get announced
New codes tend to arrive alongside content updates, and the developers post them on the game’s official Discord server. Joining that server also gives you a direct line to patch notes and bug-fix announcements that sometimes come bundled with a fresh code.
For unit stats, mechanics breakdowns, and a look at what’s planned for future updates, the Uma Tower Defense Trello board is maintained as a working reference, though it’s still labeled a work in progress.
What Carats are used for
Carats function as the game’s premium currency. You spend them on gacha summons for top-tier units, rerolling rare traits, and picking up progression items that would otherwise take much longer to earn through normal play. Since higher-tier units and traits make a real difference against tougher waves, stacking Carats from codes before a big summon session is worth doing before they get spent elsewhere.
Checking back regularly pays off since codes go inactive without warning once a new batch replaces them. Redeeming a code the moment you see it listed here is the surest way to avoid missing out on units like Tokai Teio or the Special Dreamer.
