Fishing Tower Defense pairs bait-and-catch fishing mechanics with wave-based tower defense, letting you turn rare fish into towers that fend off fishermen and human NPCs. Redeeming codes speeds up that process by handing out Diamonds and Premium Trait Rolls, the two resources that matter most for building a strong lineup of fish towers early on.

Codes are entered from a menu inside the game itself, not through a separate website.

A “This code doesn’t exist!” message almost always points to a typo, so double-check spelling and capitalization before trying again. If the game instead says a code is expired, no further redemption is possible for that one.

These codes no longer produce rewards but are kept here for reference.

What Diamonds and Trait Rolls do
Diamonds sit alongside Credits as the game’s second currency, but they’re reserved for the rarest upgrades and bait, including Squid Head bait, which improves your odds of landing the strongest fish. Those top-tier fish deal far more damage once placed as towers, so Diamonds have an outsized effect on how fast a defense lineup improves.
A Premium Trait Roll lets you re-roll the traits on a fish tower in search of better stats, which matters most once you already own a rare fish and want to push its performance further rather than catch a new one.
Where new codes get announced
New codes tend to appear alongside visit and like milestones rather than on a fixed schedule. The official Fishing Tower Defense Discord server and the supreme stu Roblox group are the two places the developer posts them first, alongside the developer’s X account.
Bookmarking this page and checking back regularly is the simplest way to catch new codes before they expire, since redemption windows can close quickly once a milestone code goes live.
