Ultimate Tower Defense puts anime and superhero units on the front line against endless enemy waves, and progress depends heavily on gold, gems, and reroll currency. Codes hand out free Perk Rerolls, Trait Rerolls, Lost Chests, and other resources that would otherwise take hours of grinding to earn.
Working Ultimate Tower Defense codes
Enter these exactly as written, since codes are case-sensitive and a single missed character will return an error.

Where new codes get posted first
New codes usually go out around updates, milestones, and holidays, and they can disappear within days. The Ultimate Tower Defense Discord server is where the developers post announcements, so checking the codes channel there is the fastest way to catch a fresh drop before it expires.
Rewards like Perk Rerolls and Trait Rerolls let players reshape a hero’s stats without spending gold on repeated attempts, while Lost Chests and Impure Souls feed into crafting and upgrade systems tied to rarer units. Redeeming codes as soon as they appear is the simplest way to stock up on these before diving into harder raids.
