Alliance Tower Defense Codes (October 2026)

200 Coins

Posted with the October 14 Halloween update: Destructoid's October 13 refresh ('We added new codes!') lists it as the newest active code, and TechWiser's October 14 refresh agrees on the 200-Coin reward. urgametips' October 14 refresh does not list it yet. Two independent trackers at the freshest checks — redeem it early anyway; event codes in this game have expired without notice before.

250 Coins

Now on two working lists at the freshest refreshes: urgametips (added October 9, still listed at its October 14 refresh) and TechWiser (October 14 refresh). Destructoid's October 13 refresh omits it from both lists. Worth trying promptly; a failure is final.

300 Coins

Added with the September 10M event and now the longest-lived working code: urgametips (October 14 refresh), TechWiser (October 14 refresh) and GameRant's October 7 refresh all list it active. Destructoid's October 13 refresh omits it from both its active and expired lists — an omission, not an expiry claim. Still capped-game economy: redeem and move on.

400 Coins

TechWiser's October 14 refresh lists it as a new working code worth 400 Coins — the only tracked source that carries the string at our October 15 check (Destructoid's October 13 and urgametips' October 14 refreshes omit it). Possibly tied to a visits milestone like September's 10M code, but no source confirms the occasion. Try it once; a failure is final.

3 Tickets (1,250-redemption cap)

The sources split at the Halloween recheck: Destructoid's October 13 refresh still lists it active (capped at 1,250 redemptions), but TechWiser's October 14 refresh moved it to expired and urgametips' October 14 refresh dropped it from both lists. With a publisher flagging it expired, treat a failed redemption as final.

200 Coins

The split sharpened at the Halloween recheck: Destructoid's October 13 refresh still lists it active, while GameRant's October 7 refresh and TechWiser's October 14 refresh list it expired and urgametips dropped it from both lists. Two expired claims against one active claim — try it once and treat a failure as final. Some publishers have also warned the code system itself can be buggy.

Party Event rewards

Released with the Party Event update. No tracked source lists it as working at the October 15 check — urgametips' October 14 refresh also dropped it from both lists — and none confirms expiry. Try it once, expect nothing.

What codes are working in Alliance Tower Defense!?

At our 2026-10-15 check, after the October 14 Halloween update: Halloween (200 Coins) is the new code of the update window — Destructoid's October 13 refresh ("We added new codes!") and TechWiser's October 14 refresh both list it active. 20m (400 Coins) is a single-source report from TechWiser's October 14 refresh — no other tracked source carries it yet. 10M (300 Coins) and SECRET (250 Coins) are now on two working lists each (urgametips and TechWiser, both October 14; GameRant also keeps 10M). FreeTicket (3 Tickets) and PASS (200 Coins) turned into disputes: Destructoid still lists both active at its October 13 refresh, while TechWiser's October 14 refresh marks FreeTicket and PASS expired and urgametips dropped both. Redeem promptly — this game's codes cap their total redemptions and expire without notice.

Where do I redeem codes in Alliance Tower Defense?

Click the Shop button on the left side of the screen, scroll to the bottom of the Shop window, paste the code into the text box, and press Redeem. Codes are case-sensitive, reject extra spaces, and work once per account.

Why does a code say Invalid?

Usually expiry, an already-used code, or a typo. This game's code system has also had reported reliability issues — some publishers explicitly warned that valid codes could fail. If PASS fails, for example, sources conflict on whether it is expired or bugged.

How often are new codes released?

With updates — the developer ships a code with most named updates (Insane with the science update, Mythic with the Mythic update, BIG with the Big Update, 10M with the 10M event, and now Halloween with the October 14 Halloween update). The official listing's title switched to [🎃 HALLOWEEN 🎃] with a modification timestamp of October 14, 2026, 23:26 UTC, and the tracker refreshes of October 13–14 carried the two new strings. This page is the first place to re-check after the next update.

Is MythicYT a real code?

We can't verify it. No code tracker or community source lists MythicYT; the August 20 Mythic-update code was MYTHIC. We removed the string from our list rather than repeat a rumor.
