How to redeem ZZZ codes

Reach Inter-Knot Level 5 so redemption unlocks.
In-game: Menu → More → Redemption Code, paste exactly, confirm, then claim mail.
Or use the official ZZZ redeem page while logged into the correct HoYoverse account / server.

What codes usually give

Polychrome — premium currency for Signal Searches
Denny — common currency
Logs / W-Engine modules — Agent and engine upgrade materials

Troubleshooting

Invalid — expired, already used, mistyped (O vs 0), wrong server, or under Inter-Knot 5.
Asia-only — some rows are region-locked (see badge).
No mail — wait a minute, then fully restart the client. Confirm you are on the intended account / server.
One redeem per code — Mark claimed here only tracks this browser; it does not contact HoYoverse.

When new ZZZ codes drop

Version Special Program livestreams usually drop short-lived Polychrome codes — redeem the same day.
Anniversary / collab / Steam / creator codes can be region- or platform-limited; check the badge.
Watch HoYoverse socials and in-game notices. After redeeming, spend smarter with the Polychrome budget and Version 3.1 claim checklist.

FAQ

Do I need Inter-Knot Level 5?: Yes for redemption / Event unlocks on most accounts. Push Prologue and early story first.
Can I redeem on web and in-game?: Yes — official gift page or in-game Redemption Code. Same code still only works once per account.
Are expired codes deleted?: No. We keep them labeled expired so you do not waste time retrying livestream leftovers.
