Tower Defense Simulator has been one of Roblox’s go-to co-op experiences since 2019. Developed by Paradoxum Games, it’s straightforward in concept — place towers, upgrade them, hold the line against increasingly brutal enemy waves — but there’s a surprising amount of depth once you get into the harder difficulties and boss fights.
Right now there are four active codes, including one that dropped recently tied to a community milestone. Nothing too extraordinary in terms of volume, but a free skin and a couple of crates are worth grabbing if you haven’t already. One thing worth knowing before you redeem: some skin codes require you to already own the relevant tower. If you hit an error, that’s usually why.
Tower Defense Simulator Active Codes
- 1MILCOMMUNITY — Free Skin [NEW]
- 2MILLION — Crate
- CHRISTMAS2025 — Christmas Crate
- NOTESLA? — Premium Skin Crate
No expiration dates have been publicly listed for any of these, but milestone codes in TDS have gone dead without warning before. Redeem sooner rather than later.

How to Redeem Tower Defense Simulator Codes
Important: If you’re redeeming a skin code, you must already own the associated tower. Without it, the code won’t go through.
- Launch Tower Defense Simulator on Roblox
- Click the Codes button in the top-right corner of the screen
- Type or paste your code into the Enter Code Here field
- Hit Redeem to collect your reward
Note that TDS won’t show an explicit error message if something goes wrong — so if nothing happens, double-check your spelling and confirm you own any required towers before trying again.
Where to Find More Tower Defense Simulator Codes
New codes are typically announced through the official TDS Discord server and the @paradoxum_games and @BelowNatural accounts on X (Twitter). The Discord is the most reliable spot — check the announcements channel rather than general chat. Joining the official Paradoxum Games Roblox group also gives you a free $100 in starting cash, which is worth doing even if you’re past the early grind
