Tower Defense Simulator — TDS to everyone who plays it — is one of the founding fathers of Roblox tower defence. You and your squad place towers along the path, pool your economy, and hold out against waves of zombies that escalate from a gentle warm-up to genuine chaos by the final rounds. Years after release it still pulls in tens of thousands of players at a time, which tells you how well the formula has aged.
Codes in TDS have never been about currency. They hand out cosmetic skins and crates instead — ways to make your towers look the part while you defend. The game goes long stretches without releasing any, so a fresh pair of working codes is a rarer event here than in most games on this list. Both strings below were confirmed by multiple sources updated in the last few days.
All New Tower Defense Simulator Codes
- 1MILCOMMUNITY: Free skin (==NEW==)
- 2MILLION: Free Crate (==NEW==)
A quick but important catch with the community skin: skin codes in this game only redeem if you already own the tower the skin belongs to. If 1MILCOMMUNITY refuses to go through, check the troubleshooting section below before assuming the code is dead — the fix is usually in your tower inventory, not in the code.

How to Get More Tower Defense Simulator Codes
When Paradoxum Games does release a code, it is announced in the official Discord server, which is also where update news and event details land first. Codes are rare enough here that patience is part of the deal. Bookmark this page and check back around major updates and holidays — those are the moments this game has historically chosen to drop something.
Why Are My Tower Defense Simulator Codes Not Working?
Double-Check for Typos: TDS codes are case-sensitive and several of the older ones are full of leetspeak — W33KLICODE and SPR1NGM1L3ST0NE will fail if you “correct” the numbers into letters. Copy each string exactly as it appears.
The Code Has Expired: Event codes in this game are switched off when the event ends, and they do not come back. CHRISTMAS2025 is a good example: it still shows as working on some out-of-date lists, but several sources updated in November 2026 confirm it has been retired.
You Don’t Own the Tower Yet: Skin codes are tied to specific towers. If a code rewards a skin for a tower you have not bought — the Pursuit or the Shotgunner, for example — the game will not let you redeem it. Buy the tower first, then enter the code again.

Conclusion
Two fresh codes is a good month by Tower Defense Simulator standards: a community skin and a free crate, both verified working right now. Grab them while the milestone celebrations are still running, make sure you own the right tower for the skin, and keep this page bookmarked for the next drop.
