Mastering how-and when-to redeem these codes will give you a powerful jumpstart: expect free Polychrome, Dennies, Investigator Logs, and valuable upgrade materials. In this guide, we’ll walk you through exactly how to claim every reward, share the latest active codes, and explain why acting fast is critical before these exclusive bonuses vanish for good. Why ZZZ Codes Matter: The Strategic Value of Free Rewards Redeem codes in Zenless Zone Zero are not just about “freebies”-they’re a key part of HoYoverse’s player engagement strategy.
