Why codes might not work

  • The code has expired; many TDS codes are time-limited or stock-limited.
  • There’s a typo or extra space; codes are case-sensitive and punctuation matters.
  • The code was already redeemed on your account.
  • The game session needs a refresh; rejoin or restart Roblox and try again.

Where to find more codes

Follow official channels for future code drops and announcements: the developers’ X profile at x.com/paradoxum_games, the Tower Defense Simulator Discord server, and the game’s Roblox page. Bookmark this page — we update code lists weekly.

Codes are case‑sensitive and can end at any time. Avoid third‑party “code generators” or suspicious links; stick to official channels for legitimate codes.
