Last Updated: October 12, 2026
The ASTD X codes most widely reported as still active are RELEASE, 1MVISITS, 10MVISITS, 50MVISITS, BIGUPDATE, SUMMER, HALLOWEEN, and XMAS — each pays out free Yen, Gems, or summon currency, and the only way to confirm one is still live is to type it into the in-game code box, because All Star Tower Defense X retires codes without announcement and without updating the in-game list. Treat any single source, including this one, as a starting checklist rather than a guarantee.
📄 In This Review
Quick answer: Our top pick in 2026 is the RELEASE — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
Active ASTD X Codes and What They Pay
Reward amounts below are the figures the community has reported most consistently across the ASTD X wiki and Discord code-tracking channels. The developers do occasionally adjust payout sizes when they re-issue a code, so a code can stay valid while paying slightly more or less than the number listed.
| Code | Reported reward | Status | Rough grind equivalent |
|---|---|---|---|
| RELEASE | 2,500 Yen + 50 Gems | Widely reported active | ~10–15 min of story runs |
| 1MVISITS | 5,000 Yen | Widely reported active | ~15–25 min of story runs |
| 10MVISITS | 10,000 Yen + 1 summon ticket | Widely reported active | ~35–50 min of story runs |
| 50MVISITS | 250 Gems | Widely reported active | ~1–2 hours of Gem farming |
| BIGUPDATE | 7,500 Yen + 2 trait rerolls | Widely reported active | ~30–45 min plus reroll value |
| SUMMER | 5,000 Yen + 100 Gems | Seasonal — may be retired | ~25–40 min combined |
| HALLOWEEN | 1 summon ticket + 150 Gems | Seasonal — may be retired | ~1–2 hours of Gem farming |
| XMAS | 10,000 Yen + 1 summon ticket | Seasonal — may be retired | ~35–50 min of story runs |
The seasonal rows are the ones to check first. Holiday codes in ASTD X have historically been kept alive for a window of a few weeks to a few months and then quietly switched off, so a code that worked last winter may return nothing today even though it still appears on older code lists.

Yen totals mean very little on their own — the useful comparison is how long the same payout would take you to farm manually. The table below uses a mid-game account clearing standard story stages at roughly 2–4 minutes per run for 800–1,500 Yen each.
| Reward type | Typical code payout | Manual farming time saved |
|---|---|---|
| Yen | 2,500–10,000 | 10–50 minutes |
| Gems | 50–250 | 20 minutes to 2 hours |
| Summon tickets | 1–2 | Equivalent to several hours of Gem saving |
| Trait rerolls | 1–3 | Highly variable; often the most valuable single reward |
That is why the ordering in the first table matters: a code paying one summon ticket is worth far more to a new account than one paying 5,000 Yen, even though the Yen number looks bigger. If you are only going to redeem three or four codes, redeem the ones with tickets and rerolls first in case the rest expire while you are typing.
How to Redeem Codes in ASTD X
- Open All Star Tower Defense X in Roblox and wait for the main lobby to finish loading.
- Look for the Codes button, usually placed along the left or bottom edge of the lobby UI near the settings and inventory icons.
- Click it to open the text field. Paste or type the code exactly as written — ASTD X codes are case-sensitive, so 10MVISITS is not the same as 10mvisits.
- Press Redeem and wait for the confirmation toast. Rewards land in your account immediately; Yen and Gems go to your balance, tickets and rerolls to your inventory.
- Repeat for each code, then close the window and check your inventory to confirm the totals moved.
If a code does not work
- “Invalid code” almost always means the code has expired or you mistyped a character. Copy-paste from a list rather than retyping.
- “Already redeemed” means the code is still live but bound to your account. There is no second payout, and no way to reset it.
- Nothing happens at all usually means the game server is behind or your session is stale. Rejoin the lobby and try again before assuming the code is dead.
- Mobile players sometimes find the codes window covered by the chat bar. Rotate the device or close chat before tapping Redeem.
Expired Codes and Community Claims to Ignore
A large share of ASTD X code lists circulating online are recycled from the original All Star Tower Defense, from other Roblox tower defense games, or from older ASTD X updates. These are the ones that come up most often and that you can usually skip:
- Original ASTD codes such as early visit-milestone strings — the two games run separate code systems, and ASTD X does not honour the older game’s list.
- Developer-apology codes handed out during specific outages. These are one-time and account-bound, and are usually dead within days.
- “Secret” or “infinite Yen” codes shared in comments or short-form video. No ASTD X code grants unlimited currency; these are engagement bait.
- Codes dated to a specific update number more than a couple of updates back. Update-tied codes are typically retired when the next major patch lands.
Which Codes Matter Most, by Player Situation
| Your situation | Redeem first | Why |
|---|---|---|
| Brand-new account, first hour | RELEASE, 1MVISITS | Yen and Gems let you pull early units instead of grinding stage one |
| Mid-game, stuck on a stage | 10MVISITS, BIGUPDATE | Tickets and trait rerolls fix the unit quality problem, not the currency problem |
| Returning after months away | Everything still live, in one session | Codes expire while you are gone; redeem the whole list before playing |
| Free-to-play, hoarding Gems | 50MVISITS, XMAS | Largest pure-Gem payouts, no ticket dilution |
| Seasonal event player | SUMMER, HALLOWEEN | Highest chance of being retired soon — check these first |
How to Catch New Codes Early
ASTD X codes are released on milestone triggers rather than a fixed schedule: visit-count thresholds, like-count thresholds, major update launches, holiday events, and compensation after server outages. That means new codes appear fastest in the official game description inside Roblox and in the developer’s own community channels, and only later on third-party list pages. If you want the codes while they are still live, check the game page itself rather than an aggregator — aggregators are typically several days behind, which is exactly the window in which short-lived codes die.
One practical habit: redeem codes the day you see them, before you play. A code you save for later is worth nothing if it expires during the next patch, and there is no way to reclaim it once the developers switch it off.
