Idle Heroes Simulator Code Guardian

Renato Estrada

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 731,005 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 Idle Heroes Simulator code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Idle Heroes Simulator 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.

About Idle Heroes Simulator

Defend your very own island against waves of enemies in Idle Heroes Simulator! To get started protecting your island, you'll need to take down your first enemy that arrives through the entry portal. Next, with any cash earned from defeating enemies, you'll be able to purchase new weapons, upgrades, and heroes for your character to use. Heroes will significantly boost your island's defensive capabilities, and each host a range of unique abilities and skills. Collect as many heroes as you can, and invite other players over to your island to show off your hard work!
