Code Guardian

Personally finds and maintains every code on this page, with around-the-clock help from the rest of our Code Guardians.

Roblox Den's code tracker continually scans Roblox.com, social channels, user reports, game developer networks and other sources, and we've had 730,648 reports from players on Works, Doesn't work and new codes. But before any code is listed on our site, or marked as Expired, our Code Guardians check in-game that it works and that its rewards and requirements are right. That's why every code you try on Roblox Den works.

  1. Checks every code in-game

    Renato tests every new Blub Defense code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Blub Defense changes how codes are claimed, adds a new requirement or launches a new promotion, Renato makes sure it's covered here first.

  3. Lists exact rewards and requirements

    Every code shows exactly what it gives and any level or gamepass it needs, so you know what you're getting before you redeem it.

Renato isn't the only Code Guardian around here: Erwin and Nicole check new codes for this game whenever Renato is away or asleep.
