How to redeem codes

Step 1: Launch Universal Tower Defense from the Roblox game page and load into the main lobby.

Step 2: Look at the game UI and find the button labeled “Codes” on the right side of the screen. Click or tap this button to open the code redemption window.

Step 3: Click into the text box in the Codes window and carefully type or paste one working code exactly as shown, including matching capital letters and punctuation.

Step 4: Press the “Redeem” button under the text box. If the code is valid and your account meets any level or access requirements, the reward notification will appear and the items will be added to your account.

Step 5: Repeat the process for each remaining code, using one code at a time, until you have claimed all the rewards you want.

Expired codes

• 40kCCU! — No longer grants Gems or Trait Rerolls.
• SorryEA! — Formerly gave Trait Rerolls.
• SorryEA2! — Formerly gave a large Gem reward.
• ThankYouEA! — No longer redeemable.

Why codes might not work

• The code has expired and the event or milestone it celebrated has ended.
• There is a typo, missing character, or extra space; codes in Universal Tower Defense are case-sensitive.
• The code was already redeemed on your Roblox account, so it cannot be used a second time.
• The game client or Roblox servers have not fully updated; closing the experience, reopening it, and trying again can help.

Where to find more codes

New Universal Tower Defense codes are typically shared through the game’s community channels, mainly the official Universal Tower Defense Discord server, as well as the links listed on the Roblox game page.

Bookmark this page — the working code list is reviewed regularly so you can quickly check for fresh freebies.

Codes are free, time-limited bonuses and always need to be entered exactly as written. They will stop working once they expire, and no third‑party “code generator” can create real Universal Tower Defense codes, so avoid any sites or tools that claim to do this.
