If the total in your inventory or currency display doesn’t change after you submit a code, the code has likely expired or was typed incorrectly.

New codes usually go out when the developer hits a subscriber or player milestone, or when a fresh update rolls out with a matching celebration code. Keep an eye on the official in-game announcements board and the developer’s own social accounts, since that’s where these drops get posted first. Checking back around major update days gives you the best shot at catching a fresh code before it expires.
Are these codes free?
Yes, every code is free to redeem and simply requires entering it correctly through the in-game code menu.
Why didn’t my code work?
A code usually fails because it has already expired or because it was entered with the wrong capitalization or missing punctuation, since the redemption box treats codes as exact text matches.
Redeeming these as soon as you load in gives you a solid head start on Trait Rerolls and Gems before you start building out your tower lineup.
