Fighting without lifting a finger? That’s the whole idea behind Idle Fighters, your heroes do the work while you stack rewards. But progress slows fast without boosts, so you’ll want to grab every working code below.
These Idle Fighters codes hand out free Coins, Gems, and Boosts — perfect for faster upgrades, stronger heroes, and less waiting between milestones.
Working Idle Fighters Codes
Copy and paste exactly as shown — they’re case-sensitive and change often with each update.
- BARRY10OCT25: 5 Core of Transcendence, 999 Gems
- GIFT10LUTZ: 10 Heroic Summon Scrolls, 10 Core of Transcendence, 1,000
- IH999: 60 Heroic Summon Scrolls
- IH777: 40 Heroic Summon Scrolls (must clear campaign stage 3-10)
Quick tip: If a code doesn’t work on your first try, switch to a public server. Idle Fighters sometimes delays updates on private ones.
