How to Redeem Tower Defense Simulator Codes

Tower Defense Simulator has kept its redeem box in the lobby across every event, so the steps have not changed in years — only the codes have.

Where is the redeem button?

Open the lobby menu and look for the codes button beside the settings and shop icons.

Full step-by-step guide

  1. 1 Join a lobby rather than a match; the box is not available mid-wave.
  2. 2 Open the menu and find the codes entry, usually next to settings.
  3. 3 Paste one code at a time and confirm each before moving on.
  4. 4 Check the inbox or inventory for skins; crates arrive unopened.
  5. 5 Redeem the crate-style codes before the seasonal event shop closes.
  6. 6 Re-check the list after each major update, since this game retires codes in batches.

Codes not working? Try these fixes

The codes button is missing

You are probably in a match rather than the lobby. Leave the round and open the menu again.

A code shows as invalid

This game has retired codes in bulk at least once a year. Most strings older than a year are dead, including several that still appear on archive pages.

Where do redeemed skins go?

Into your inventory as equippable skins rather than being applied automatically. Equip them from the tower customisation screen.

Do codes work in private servers?

Yes. The box is a lobby feature, so private lobbies work the same as public ones.

How a code gets on this page

  1. Every code points at a source

    Each line shows where the code came from and the date we last looked at it. If we cannot point to an official channel for a string, it does not go on the page.

  2. Reports downgrade, they do not delete

    When several players report the same code failing, it moves to “Worth a try” until it is re-checked. One bad report never buries a code that still works.

  3. Three states, no guessing

    Active means confirmed working. Worth a try means the source is solid but we have not confirmed it in-game. Expired means it was tried and failed.
