What are the latest working All Star Tower Defense X codes?

Six codes are currently reported active across multiple trusted gaming guides. Below is the full lineup with exact rewards and source verification.

Which codes are still active in May 2026?

Six codes, all tied to the Mega Update 9 release or earlier patches, are still working. The table below lists each code, its rewards, and the publisher that confirmed it as of May 2026.

The update-themed codes deliver the biggest payouts.

The pattern: update-themed codes pack the most value and expire fastest.

Redeem these codes quickly to maximize gem earnings.

How many codes are available now?

Most guides agree on six active codes. Some sources also list bigcode3, game11, DELAYYY5, and TRAITPITYADDED (Pro Game Guides), but those may already be expired or server-specific. We recommend trying the six above first.

How do I redeem codes in All Star Tower Defense X?

The redemption process is straightforward, but missing one step can leave you staring at an error message. Here’s the exact sequence, drawn from All Star Tower Defense Codes (community guide) at allstartowerdefensecodes.com and Pocket Tactics.

Where is the code input box located?

1. Launch All Star Tower Defense X on Roblox.
2. Click the bird/Twitter icon in the bottom-left corner of the screen.
3. Type or paste your code into the text box exactly as shown (case matters).
4. Click Redeem and the rewards will appear in your inventory immediately.

Pocket Tactics notes that some codes require at least level 2 to redeem; if you’re below that, the button may stay greyed out (Pocket Tactics).

What if the code doesn’t work after entering it?

• Try a private server. Public servers sometimes run older instances that don’t recognise new codes. Join a private server and try again (Fandom Wiki).
• Double-check spelling. Codes are case-sensitive. A capital letter where a lowercase belongs will fail.
• Check for a level requirement. If you’re below level 2, you won’t be able to redeem at all.

Double-checking the server and spelling prevents most redemption failures.

How often are new All Star Tower Defense X codes released?

There’s no fixed calendar, but a clear pattern has emerged: codes almost always drop with major game updates.

When was the last batch of codes released?

The most recent wave came with Mega Update 9 in May 2026, introducing three new codes at once (Beebom). Earlier in 2026, UPDATE7ORISIT8 and TRAITPITYADDED arrived with a previous patch (Pro Game Guides).

How can I stay updated on new code drops?

Since the developer doesn’t publish an official code Twitter, your best bets are gaming news sites like IGN (Roblox wiki) and Eurogamer, which update their code lists within hours of a new update.

Act fast: event codes disappear with their event.

Why are my All Star Tower Defense X codes not working?

When a code fails, it’s almost always one of four reasons. Here’s how to diagnose each one.

What does ‘code expired’ mean?

Most codes have a limited redemption window — sometimes just a few weeks. Once expired, the game returns a “this code has expired” message (Pocket Tactics). No fix exists except waiting for a re-release.

Why does the code say ‘already redeemed’?

Each code can only be claimed once per account (The Spike). If you’re absolutely sure you haven’t used it, try a private server — your progress is saved server-wide, so a different server won’t reset the claim status.

• Expired: No workaround — remove it from your list.
• Already redeemed: Check your inventory. If the rewards are missing, contact Roblox support.
• Wrong server: Switch to a private server and try again.
• Typo: Re-enter the code exactly as shown, including all caps and symbols.

Four failure types, one pattern: three of them are preventable by double-checking the code source and server. The trade-off: you can’t fix expired codes — they’re gone for good.

What rewards do All Star Tower Defense X codes give?

Rewards fall into a few standard categories: gems, trait burners, and bounded cubes. Some codes also include event-specific items like jack-o’-coins.

Which code gives the most gems?

The biggest gem payout is 2,500 from UPDATE9, SPRINGOWEENRELEASED, THANKYOUFORPLAYINGLOVE, and LIMITEDTIMECODEX. That’s enough for multiple unit rolls or a top-tier summon attempt.

Are there codes for exclusive items?

Event codes like soww (85 jack-o’-coins) are the only ones that offer seasonal currency. No current codes grant exclusive units or characters (Eurogamer).

Seven rewards, one pattern: gems are the universal currency, trait burners let you re-roll unit perks, and bounded cubes are used for high-end upgrades. None of these rewards are tradeable, so they’re strictly for advancing your own account. Why this matters: stacking multiple code rewards can give you a week’s worth of grinding in five minutes — if you act before they expire.

Clarity check

Confirmed facts

• UPDATE9 gives 2,500 Gems, 85 Trait Burner, 20 Bounded Cube (Pocket Tactics)
• SPRINGOWEENRELEASED gives identical rewards (Pocket Tactics)
• Codes require exact capitalization (The Spike)

What’s unclear

• Exact expiration dates of any code
• Whether codes can be used more than once per account
• Official list from developers – no direct source exists
• Whether private servers consistently fix redemption errors (Fandom Wiki – unconfirmed)

Uncertainties remain, but the confirmed facts give a solid foundation for redeeming codes today.

Quotes from the guides

If a code doesn’t work, try again in a new or Private Server as you might be in an older server that was created before the new code came out.

Beebom (tech news)
