Idle Horizons mixes auto chess strategy with idle RPG progression, putting the focus entirely on team composition and theory-crafting. Because building optimal lineups takes time and trial, promo codes give you a head start by dropping extra supplies straight into your inventory.
Redeeming the current active codes provides a wave of free bonuses to help you test different unit synergies without hitting an early progression wall. Whether you want to experiment with new setups or speed up your idle gains, these freebies make tweaking your board far easier.
We check for fresh codes every day and update our lists immediately, so you never miss out on active redemption drops. Be sure to bookmark this page and check back regularly as new gifts arrive.
