How to redeem
Step 1: Open Universal Tower Defense
Launch UTD on Roblox and wait for the main lobby to load fully.
Step 2: Open the Codes menu
Look for the Codes button/menu option in the UI (usually in the lobby).
Step 3: Paste the code exactly
Codes are case-sensitive. Avoid extra spaces before/after the code.
Step 4: Redeem and check rewards
Redeem the code, then confirm Gems / Trait Rerolls / rewards were added.
Troubleshooting
“Invalid code” / “Code not found”
The code has likely expired or was typed with an extra space. Copy-paste and remove trailing spaces.
Redeem button does nothing
Rejoin a fresh server or restart Roblox. Some updates require a new server instance.
Already redeemed
Most UTD codes are one-time per account. If you redeemed it before, it will not work again.
