Universal Tower Defense Codes (February 2026) — Current status and full list

Update: We looked for new Universal Tower Defense codes on February 25, 2026, but there are no active codes right now.

Universal Tower Defense on Roblox uses redeemable codes to grant free Gems, Trait Rerolls, Stat Rerolls, Stat Locks, Ice Gifts, Gold, Spirit Souls, shards, and fragments. These rewards help you summon new units and optimize their traits and stats without extra grinding.

Universal Tower Defense codes status (February 2026)

As of late February 2026, all previously known Universal Tower Defense codes are treated as expired. Multiple current references agree that there are no active or working codes right now, even though a large number of historical codes exist.

Because of this, the table below lists every known code with its last known reward, but all are marked as Expired so you can quickly see that they are for reference only. You can still try them in case any are reactivated, but you should expect them not to work.

How Universal Tower Defense code rewards work

Universal Tower Defense codes are one-time strings that, when valid, grant account-wide rewards. Historically, these rewards have fallen into a few clear categories.

• Gems are the core currency for summoning new units. High-value codes (for example 4000 or 10,000 Gems) significantly speed up team building.
• Trait Rerolls let you randomize traits on your units to chase stronger combinations. Many codes focus heavily on Trait Rerolls.
• Stat Rerolls and Stat Locks give finer control over unit stats, allowing you to reroll and then lock favorable outcomes.
• Ice Gifts, Gold, and Spirit Souls support seasonal or progression systems, particularly around winter events.
• Etherealization Shards and Evo Fragments are rarer upgrade materials used for advanced unit evolution paths.
• Some event codes also unlock extras like a Winter Lobby OST.

Once redeemed successfully, the reward items are added directly to your account balances or inventories with an on-screen confirmation.

How to redeem Universal Tower Defense codes

Step 1: Launch Universal Tower Defense on Roblox and wait until you are fully loaded into the lobby.

Step 2: Look at the right-hand side of the screen and click the blue Codes button (in some versions you may instead use the shop interface, but the dedicated Codes button is the primary method).

Step 3: In the redemption window that appears, carefully type a code exactly as shown in the table above, matching capitalization and punctuation, then press the Redeem button.

Step 4: If the code is valid and active, a pop-up will confirm the rewards and your currencies or items will increase immediately. If the code is expired, invalid, or already used on your account, you will see an error message and no items will be added.

Why Universal Tower Defense codes may not work

When you attempt to redeem a Universal Tower Defense code and it fails, it usually comes down to one of a few simple reasons.

• The code is expired. All codes listed above are currently treated as expired, so redemption attempts are expected to fail.
• Typing mistakes. Missing exclamation marks, extra spaces, or incorrect capitalization will cause an error. Copying and pasting the exact string removes this risk.
• Level requirements not met. Some historical codes required minimum account levels (such as 5, 10, 15, 20, or 25). If similar requirements return on future codes, you will need to reach the required level first.
• Server or client version issues. New codes sometimes arrive alongside game updates. If a fresh code appears in the future and fails immediately, restarting the client after updating can be necessary.

When a code works, you always see a confirmation pop-up and an immediate change in your balances. If you do not see both, treat the redemption as unsuccessful.

To be ready for the next wave of Universal Tower Defense codes, keep an eye on official announcements and the in-game Codes button. When new working codes are released, the same redemption process will apply, and you can use the historical rewards above as a benchmark for what to expect.
