Universal Tower Defense X Codes
Codes give free Trait Rerolls, Gems, Universal Gems, fragments, and sometimes whole units — the fastest way to power up early. Tap Copy, then paste the code in-game exactly as shown (they're case-sensitive).
New codes are tracked automatically from the official UTDX Discord when the integration is
configured. See patch notes for the latest update.
Codes expire fast
This list reflects codes circulating around the Festival Finale (June 2026). Some may have expired.
If one fails, it's likely retired — check the in-game Codes menu or the official Discord.

How to Redeem Codes

- Click the Codes button on the right side of the screen.
- Paste a code into the text box (copy it from above to avoid typos).

Tip
Many codes have a level requirement, so play through the first chapter before redeeming. If a code
says "invalid," it has likely expired.
About Codes
