Tower Defense Simulator hands out codes every so often, and you can trade them in for tower skins, crates, and other cosmetic rewards without spending Robux. If you’ve got a few minutes before your next wave, it’s worth punching in the current batch before Paradoxum Games swaps them out.

How to redeem codes in Tower Defense Simulator
Redeeming a code takes place from a single screen once you’re inside the lobby, and it only takes a moment.
You’ll know it worked when a confirmation message pops up saying the reward has been added to your account. If you enter a skin code and nothing seems to happen, check that you already own the tower the skin belongs to — skin codes only apply their reward on top of a tower you’ve unlocked.
Expired Tower Defense Simulator codes
These codes have already been used up or pulled by the developers, so don’t waste time trying them.

How to get more Tower Defense Simulator codes
Paradoxum Games typically drops new codes around milestones like player count achievements, holidays, and game anniversaries, so they don’t show up on a fixed schedule. Your best bet is to keep an eye on the studio’s official Discord server, where announcements about new codes usually land first. You can also check the Paradoxum Games Roblox group for updates tied to the game.
If you want to jump straight into a match while you wait for the next code drop, you can load up Tower Defense Simulator on Roblox and check the Codes menu directly, since new entries appear there as soon as they go live.
Why didn’t my code work?
Double-check your spelling first, since codes are case-sensitive and some, like NOTESLA?, include punctuation that’s easy to miss. If the code is expired, the redemption box will simply refuse to give you anything, and there’s no way around that other than waiting for a fresh code.
Keep your Codes menu open the next time you’re in the lobby and you won’t miss a new drop.
