You’ve probably been there. You're staring at a wave of enemies in All Star Tower Defense (ASTD), your units are struggling, and you just need that one extra summon to turn the tide. You go looking for All Star Tower Defense codes, hoping for a quick infusion of Stardust or Gems, only to realize half the "active" lists on the internet are total junk. It's frustrating. Honestly, the way the ASTD developers handle codes has changed significantly over the last year, and if you're still looking for them the same way you did in 2022, you're going to come up empty-handed most of the time.
Roblox games are notorious for this. A developer drops a code, it expires in three hours, and then SEO-hungry websites keep that code on their "Active" list for six months just to get your click. It’s a mess.
The Truth About Stardust and Gems
Let’s get real about what these codes actually do for your account. In the current meta, Gems are fine for basic pulls, but Stardust is the actual currency of kings. If a code doesn't give you Stardust, is it even worth the thirty seconds it takes to type it in? Maybe. But for high-level players looking to snag those elusive 7-star units or limited-time banners, the code economy has become much more stingy.
The developers, led by Fruity and the Top Tier Production team, have moved toward a system that rewards playtime and specific event participation over simple handouts. This is a common shift in massive Roblox titles. They want you in the game, not just popping in for a code and leaving. That's why you'll notice that the most valuable All Star Tower Defense codes often come with "time played" requirements. You can’t just make a fresh alt account and dump a bunch of codes to get a head start; the game will literally block you from redeeming them until you’ve hit a certain level or played for a specific number of minutes.
How to Actually Find Working Codes
Stop using random Google searches. Seriously. By the time a "Top 10 Codes" article is indexed, the codes are usually dead. If you want the real stuff, you have to go to the source.
The official ASTD Discord is the only place where you get the raw data. Even then, it’s chaotic. You have to navigate through various channels, avoid the general chat (which is usually a cesspool of "pls trade" spam), and look for the announcements or "sub-to-the-devs" updates. Twitter—or X, whatever we’re calling it this week—is the second-best bet. Following Fruity or the official game account is the only way to catch the flash codes that only last for an hour during a major update or a milestone celebration.
Another thing people miss? The YouTube codes. Some developers give specific codes to big-name ASTD creators to drive traffic to their videos. These are "exclusive" in the sense that they aren't always posted on the main Discord immediately. It’s a marketing tactic. It works, but it’s annoying for the average player who doesn't want to sit through a ten-minute video just to find a ten-digit string of text.
Why Codes Expire So Fast
It’s all about the economy. If everyone has 50,000 Gems, then the rarity of a "Rare" unit becomes zero. The developers have to balance the influx of currency. When an update drops—let's say a new World or a massive shift in the PVP meta—the devs release codes to get people hyped. But if those codes stayed active forever, the power creep would be uncontrollable.

We saw this happen with several other tower defense games on the platform. They gave away too much, the veteran players got bored because they had everything, and the game died. ASTD has stayed on top because they are incredibly stingy with their "All Star Tower Defense codes." They make you work for it.
Common Misconceptions and Scams
There is no such thing as a "Mega Code" that gives you a 7-star unit for free. If you see a thumbnail on YouTube claiming "CODE FOR FREE KURUUMI" or something similar, it’s fake. Period. Codes in ASTD give you currency (Gems, Stardust) and occasionally XP III or IV units. They do not give you the top-tier units directly.
Also, watch out for the "Code Generators." These are classic phishing scams. They ask for your Roblox username and tell you to complete a survey to "unlock" the code. Don't do it. There is no external database for these codes; they are hard-coded into the Roblox server scripts by the developers. No website can "generate" a code that the developers didn't create themselves.

The Level Requirement Barrier
This is the part that trips up most returning players. You find a valid code, you type it in, and you get an error message that says "Requirements not met." It’s not broken. You just haven't played enough.
Most significant codes now require you to be at least Level 40 or have played for at least 2 hours. This was implemented to stop the massive bot farms that were redeeming codes on thousands of accounts to "roll" for top-tier units and then sell those accounts on third-party sites. It’s a bit of a pain for new players, but it actually keeps the trading economy from completely collapsing.
Using Codes Strategically
Don't just spend your Gems the second you get them from a code. That’s a rookie move. The best way to use your code rewards is to wait for a banner that features a unit essential for the current "Infinite" mode meta.
- Save Stardust for the "Z" Banners: These are where the real power lies.
- Gems are for fodder and mid-tier upgrades: Don't expect to win the game with just Gem pulls.
- Check the "Active" window: Most codes drop on Friday nights or Saturday mornings (EST) when the player count peaks.
If you’re sitting on a pile of Gems from a recent update, check the Discord’s "Unit-Tiers" channel first. See what the pros are using. There’s no point in burning 2,000 Gems on a unit that just got nerfed into the ground in the latest patch.
The Future of Rewards in ASTD
Expect fewer codes. That sounds pessimistic, but it's the direction the game is heading. The developers are leaning more into "Daily Tasks" and "Battle Pass" styles of progression. Codes are becoming "Event Only" treats. This is actually better for the long-term health of the game, even if it feels bad in the short term when you're broke.

The shift toward "Task-Based" rewards means you actually have to play the game. Imagine that. But for those of us who have been playing since the early days, those All Star Tower Defense codes will always hold a special place. They’re that little boost that might just get you the unit you need to finally clear that one stubborn stage in Story Mode.
Actionable Next Steps for Players
If you want to maximize your gains, stop refreshing dead websites and do this instead:
- Join the Official Discord: Turn on notifications for the #announcements channel only. Ignore everything else to save your sanity.
- Hit Level 40 Fast: Grind the lower Story Mode levels or join a "carry" session in Infinite mode. Most codes are useless to you until you hit this threshold anyway.
- Follow "Fruity" on X: This is where the "Oops, the server crashed, here’s a code" updates happen. They usually expire within 2 hours, so you have to be fast.
- Check the Banner Rotation: Before redeeming, make sure the current banner actually has something you want. Gems in the bank are better than a bad unit in your inventory.
- Verify the Code Format: ASTD codes are case-sensitive. "CodeName" is not the same as "codename." Most people who think a code is broken just have a typo or an accidental space at the end of the string.
Stay smart about it. The game is designed to be a grind, and while codes help, they aren't a substitute for a solid strategy and a well-balanced team of units.
