🗼 Tower Defense Simulator Codes (June 2026)
Tower Defense Simulator (TDS) is one of Roblox's longest-running and most popular tower defense games, challenging players to build and upgrade a squad of towers to survive increasingly difficult waves of enemies. The developers periodically release promo codes that unlock free skins, crates, coins, and gems — giving both new and veteran players a head start. We verify and update this list of Tower Defense Simulator codes every month so you always have the most accurate information available.

FAQ
How many Tower Defense Simulator codes can I redeem?
Each code can only be redeemed once per account. You can redeem as many different codes as are currently active, but entering a code a second time on the same account will return an error.
Why is my Tower Defense Simulator code not working?
The most common reasons are: the code has expired (TDS codes have no fixed end date and can expire without warning), you mistyped it (codes are case-sensitive and some include special characters like '?'), or you've already redeemed that code on your account.
Where can I find new Tower Defense Simulator codes?
New codes are announced on the official TDS Discord server and the developer's X (Twitter) account. Following those channels is the fastest way to catch limited-time codes before they expire.
What rewards do Tower Defense Simulator codes give?
Codes typically reward Skincrates (which grant cosmetic tower skins), Premium Skincrates, Coins, Gems, or specific named skins. Coin and Gem rewards help you unlock and upgrade towers faster.
Do Tower Defense Simulator codes expire?
Yes. The developers do not announce expiration dates, so codes can stop working at any time. Older seasonal codes like CHRISTMAS2025 or MERRY2024 are almost always expired after their respective events end.
Does the 2MILLION code work without the Pursuit tower?
No. The 2MILLION code rewards the Mercenary Pursuit skin, which is a cosmetic variant of the Pursuit tower. You must already own the Pursuit tower on your account to claim and use this skin.
