How we check: every code on this page is cross-checked against Tower Defense Simulator’s official channels, and we only list a code as active when the evidence agrees. Codes are copied character-for-character, so capital letters, numbers and symbols are exactly what the game expects.

Tower Defense Simulator (TDS) is the game that helped define the tower defense genre on Roblox. Paradoxum Games released it in June 2019, and it has passed five billion visits: you place towers along a path to stop waves of zombies, team up with friends against tougher bosses, and unlock new units as you go. The game is on Version 2.12.0, the Executioner Rework, as we write this.

Codes in TDS are unusual. Instead of cash or gems, most of them unlock skins for specific towers, and they are tied to community milestones such as a million likes. That makes them cosmetic rather than powerful, but they are permanent once redeemed.

Active Tower Defense Simulator Codes

2MILLION Mercenary Pursuit skin (you need the Mercenary tower)
1MILCOMMUNITY A Community Shotgunner skin . You must have the Shotgunner Tower to claim this code
SubToSageProdigy Coins

Codes are case-sensitive — copy them with the button so capital letters, numbers and symbols come out exactly right, and redeem them soon, because codes can expire without notice.

How to Redeem Tower Defense Simulator Codes

Launch Tower Defense Simulator from the Roblox app and load into the lobby.
Press the Codes button in the top-right corner of the screen.
Type or paste the code into the box and redeem it.
Skin codes only work if you already own the tower they belong to, so unlock it first.

What Tower Defense Simulator Codes Give You

The active code, 2MILLION, gives the Mercenary Pursuit skin, which the developers announced on the game’s page as a thank-you for reaching two million likes. A skin changes how a tower looks and does not change its stats, so this is a purely cosmetic reward.

The reported 1MILCOMMUNITY code follows the same pattern and unlocks a Community Shotgunner skin, again only for players who own the Shotgunner tower. For a boost you can actually feel, join the Paradoxum Games Roblox group: the game’s description says group members start every match with an extra $100.

Why Aren’t My Tower Defense Simulator Codes Working?

The most common reason a TDS code fails is that you do not own the tower it is for, since a skin code needs its tower unlocked. After that, check the code is typed exactly, that you are using the Codes button in the lobby rather than in a match, and that you have not redeemed it before.

When Does Tower Defense Simulator Get New Codes?

Paradoxum Games releases codes mainly for community milestones such as likes and follower counts, and occasionally for holidays. The current game description highlights the most recent one, so checking the page after each big update is the quickest way to spot a new code.
