Idle War blends strategic team management with accessible idle mechanics, letting you gather a diverse roster of heroes to power through a fantasy-themed campaign. Balancing your resources is a constant challenge, as currencies like Diamonds, Soul Shards, and Ace Crystals are essential for upgrading your squad and keeping your progression steady during periods of inactivity.
Using official codes is the most efficient way to bolster your inventory without spending real money. These bonuses provide a helpful push for both new players and veterans looking to expand their hero collection or sharpen their team’s combat efficiency.
Updated October 2026, this list provides all current rewards available for your account. We recommend redeeming these as soon as possible, as older codes often expire without warning as new promotional campaigns take their place.
