Update: We looked for new Tower Defense Simulator codes on February 19, 2026, but there are no active codes right now.
Tower Defense Simulator on Roblox uses limited-time codes to grant items such as crates, skins, EXP, Coins, and Gems. These codes are created and controlled by the developer and can expire or be disabled at any time.
Tower Defense Simulator working codes (February 2026)
All reliable February 2026 references agree that there are no confirmed working Tower Defense Simulator codes right now. Several previously active codes have been moved into “expired” status, including recent seasonal rewards.
Because codes are turned on and off entirely on the developer side, you cannot force a code to work once it has been disabled. Any site or video currently claiming a large list of “working” codes for February 2026 is very likely repeating old, now-expired codes.
Recently expired Tower Defense Simulator codes
The following codes are known to have been active in late 2024 and 2025 but are now treated as expired in February 2026. They are listed here purely for reference and historical verification; they should not be expected to redeem successfully.

How to redeem codes in Tower Defense Simulator
When new codes are released again, they are redeemed entirely inside the Tower Defense Simulator lobby. The redemption UI is built into the experience and does not require any external website.
Step 1: Launch the Tower Defense Simulator experience on Roblox and wait until your avatar loads into the main lobby.
Step 2: Look for the Codes button in the lobby UI. Depending on the current interface version, this appears either near the top-right of the screen or as a button with a Twitter/X icon near the bottom of the screen.
Step 3: Click the Codes button. A text field labelled for entering a code will open.
Step 4: Carefully type or paste a code exactly as provided. Codes are case-sensitive, and extra spaces before or after the text can cause them to fail.
Step 5: Press the Redeem button. If the code is valid and still active, a confirmation message appears and the reward (such as a crate, XP, Coins, Gems, or a cosmetic) is added to your account.
If nothing happens, or if a message such as “expired” or “invalid” appears, the code is no longer active or has been entered incorrectly.
Note: For skin-focused codes, you must already own the corresponding tower before you can receive the skin. If the tower is missing from your inventory, the redemption will not complete even if the code itself is active.
How Tower Defense Simulator codes behave
- Manual, limited-time creation: Codes are manually set up by the developer, often for milestones or seasonal events. They usually have a fixed activation window and can be turned off without warning.
- Account-level redemption: Each account can redeem a given manual code only once. Merchandise codes tied to physical products were unique, single-use keys and are no longer issued; their rewards are now available through an in-game Merch Shop.
- Fraud and ban risk: Any attempt to use or share codes generated through fraud or other illegal methods can lead to a ban from Tower Defense Simulator. Only use codes distributed through official channels such as the developer’s social posts or in-experience announcements.
- Tower ownership checks: When a code rewards a skin or cosmetic for a specific tower, the game checks whether you own that tower. If not, the code cannot grant the reward.
Where new Tower Defense Simulator codes usually appear
New codes are typically announced around major updates, holidays, or large visit/like milestones. The developer uses in-game notices and official community channels to distribute them. The official Roblox game page and the developer’s social accounts are the most reliable places to watch for future code announcements.
Until new codes are activated again, the most dependable ways to gain rewards are normal progression: playing matches to earn Coins and Gems, claiming login and playtime rewards, and completing quests and missions for XP and other items.
