If you’ve played Tower Defense Simulator for more than a few minutes, you already know how crazy it can get once the harder waves start rolling in. One second you’re chilling, the next you’re swarmed by zombies, bosses, and all kinds of spooky enemies. Having the right towers in place is the only way to survive, but codes can give you a little bonus on the side. Free crates, skins, and sometimes even special rewards – it all helps.
Right now, there aren’t many active codes, but there is one you can grab in November 2025. And honestly, with TDS, you never know when the devs will drop another one, so you might as well claim it while it lasts.
What’s Tower Defense Simulator Again?
For anyone just jumping in, Tower Defense Simulator (or TDS, because no one wants to type the full name every time) is a Roblox game made by Paradoxum Games. It’s been around since 2019, which is a long time in Roblox years, and it’s still going strong with over 1.5 billion visits.
The gameplay’s pretty straightforward: you and your squad drop towers around the map to stop waves of enemies from reaching your base. Towers range from simple soldiers to snipers and even cowboys, which is honestly one of the fun ones. As you grind, you unlock upgrades and new units, which lets you take on tougher maps and scarier bosses.
The cool part? The devs sometimes toss in codes for milestones or events. Not often, but when they do, it’s usually worth logging in just to grab them.
Active Tower Defense Simulator Codes (November 2025)
Here’s the one code that’s actually working this month:
- NOTESLA? – 1 Free Premium Skin (NEW)
- 4BVisits – gives you a free Premium Crate (NEW)
This code was released because TDS hit 4 billion visits. That’s a huge number, and it’s wild to think how many players have hopped in over the years. If you haven’t redeemed it yet, don’t wait around.
Expired Codes (Don’t Bother Trying These)
There used to be quite a few, but most of them are dead now. A few names you might remember:
- JOHNRETURNS
- COMMUNITY20
- HAPPY3AST3R!
- celebration21
- TDS5YEARS!
- BLOXY21
- MERRY2024
- IMCONSUMING
- 1BILLION
and a bunch more…
All of these stopped working, so the only one that matters right now is 4BVisits.
How Do You Redeem Codes?
If you’re not sure where to enter the code, here’s the quick rundown:
- Open Tower Defense Simulator on Roblox.
- Once you’re in the main lobby, look on the left side of your screen for the little Twitter bird icon.
- Click it, type in the code 4BVisits, and then hit redeem.
- If it works, you’ll see the Premium Crate pop into your inventory.
If it doesn’t work, either it’s expired or there’s a typo. Codes in Roblox can be picky, so copy it exactly as written.
Where Do New Codes Show Up?
The thing with TDS is that codes don’t drop all the time. Sometimes months go by without a new one. But if you want to stay on top of it, here’s where they usually show up first:
- The official Tower Defense Simulator Twitter (X) account
- The Paradoxum Games Discord server
- The game’s page on Roblox itself
- Big gaming blogs like Pro Game Guides or Pocket Tactics
Checking those once in a while will save you from missing out. if you don’t to search here and there for the codes, just bookmark this page, so that you don’t miss the most recent code to grab.
Why Bother With a Premium Crate?
So, what’s in the crate? The Premium Crate doesn’t change the power of your towers, but it does unlock skins. Skins are cosmetic only, but let’s be real, half the fun in Roblox is showing off. A cool-looking tower just feels better, even if it doesn’t do more damage. Plus, it’s free—so there’s really no reason not to redeem it.
Wrapping It Up
Tower Defense Simulator isn’t a game that throws codes at you every week. They’re rare, but when they arrive, they’re usually tied to something big. Right now, 4BVisits is the only active one, and it’s worth using while it’s available.
Keep an eye on official pages and communities if you want to be one of the first to grab the next code. And of course, check back here – we’ll update this list as soon as something new drops.
