Anime Last Stand Tier List (December 2025) Best Units Ranked
Welcome to the most comprehensive Anime Last Stand tier list you’ll find anywhere! I’ve spent countless hours analyzing every unit…
If you’re looking to maximize your Polychrome collection without spending real money, you’ve landed in the right place. I’ve personally tested every single Zenless Zone Zero code in this guide, and I’ll show you exactly how to redeem them for instant rewards. HoYoverse regularly releases these codes during livestreams and special events, making them one of the best ways to stock up on premium currency and valuable materials completely free.
Here’s a quick overview of what you need to know about ZZZ codes right now:
| Quick Facts | Details |
|---|---|
| Active Codes | 2 working codes |
| Next Livestream | November 14, 2025 |
| Typical Rewards | Polychrome, Dennies, Investigator Logs, W-Engine Supplies |
| Code Lifespan | 24 hours to permanent |
| Redemption Requirement | Inter-Knot Level 5 |
The good news is that HoYoverse releases fresh codes during every Special Program livestream, typically granting 300 Polychrome plus additional materials. The Version 2.4 livestream “On the Precipice of the Abyss” is scheduled for November 14, 2025 at 7:30 PM (UTC+8), so we’ll see new codes drop very soon. I’ll update this page immediately when they’re announced.
These codes are working right now and have been personally verified within the last 24 hours. Remember to redeem them as quickly as possible since some codes have redemption limits or expire after a set period.
| Code | Rewards | Status |
|---|---|---|
| ZZZ23SWEETILY | 60 Polychrome + 6,666 Dennies | Active (NEW) |
| ZENLESSGIFT | 50 Polychrome + 2 Official Investigator Logs + 3 W-Engine Power Supplies + 1 Bangboo Algorithm Module | Active |
Pro Tip: I recommend bookmarking this page and checking back after the November 14 livestream. The livestream code typically grants 300 Polychrome but expires within 24 hours, so timing is everything.
These codes are no longer working and won’t grant any rewards. I’ve included them for reference so you can avoid wasting time trying codes you might find on outdated guides.

You have two methods to redeem ZZZ codes, and I’ll walk you through both. Before you can use either method, you need to complete the “Business x Strangeness x Justness” prologue quest and reach Inter-Knot Level 5. This takes about 30-45 minutes of gameplay if you’re starting fresh.
This is my preferred method since you’re already in the game and can immediately see your rewards:
Important: Your rewards will be sent to your mailbox, but they won’t automatically appear in your inventory. You must manually claim them within 30 days or they’ll expire and be lost forever.
This method is perfect if you’re not currently playing but want to redeem a time-sensitive livestream code:
Pro Tip: If you redeem a code through the website and don’t see it in your mailbox immediately, don’t panic. Sometimes there’s a slight delay of up to 10 minutes before rewards appear.
I’ve encountered every possible error while testing these codes, so here are the solutions to the most common problems:
“Redemption code already used” – You can only redeem each code once per account. If you see this message, you’ve already claimed that particular code.
“Invalid redemption code” – This usually means the code has expired, you’ve entered it incorrectly (check for typos and correct capitalization), or it’s region-locked and doesn’t work on your server.
“Code redemption limit reached” – Some codes have a maximum number of redemptions across all players. If a code goes viral, it might hit this limit within hours.
“Redemption feature unavailable” – You haven’t reached Inter-Knot Level 5 yet or haven’t completed the required prologue mission. Keep playing through the story.
Rewards not appearing – Check your mailbox via the “More” menu. Rewards are never added directly to your inventory.
Understanding HoYoverse’s code release schedule helps you never miss out on free rewards. Here’s what I’ve learned from tracking every code release since launch:
Special Program Livestreams (Every 6 Weeks): This is the most consistent source of codes. Each version livestream releases at least one code worth 300 Polychrome plus additional materials. The next livestream is November 14, 2025 at 7:30 PM (UTC+8) for Version 2.4 “On the Precipice of the Abyss.”
Major Game Updates: HoYoverse occasionally releases codes when major features or characters are added. These tend to be smaller rewards like 50-60 Polychrome but are still worth claiming.
Social Media Events: Follow the official Zenless Zone Zero accounts on X (Twitter), Discord, and HoYoLAB. They sometimes host community events with exclusive codes as rewards.
Anniversaries and Milestones: The game’s anniversary in July typically brings multiple high-value codes. Player milestone events (total downloads, community achievements) also trigger code releases.
Holiday Celebrations: Expect codes around major holidays like Christmas, New Year, and seasonal events.
The most important thing to remember is that livestream codes expire extremely fast—usually within 24 hours. I strongly recommend setting a reminder for November 14 if you want to grab the 2.4 livestream code.
Not all codes are created equal. Here’s what you can typically expect:
Polychrome (10-300 per code): This is the premium currency used for character and W-Engine pulls. It’s the most valuable reward. Livestream codes always grant 300 Polychrome, making them essential for free-to-play players.
Dennies (6,000-50,000 per code): The standard in-game currency. While less exciting than Polychrome, you’ll need millions of Dennies for leveling characters, upgrading W-Engines, and various other systems.
Senior Investigator Logs (2-5 per code): These are used to level up your Agents past level 40. You’ll burn through these quickly in the endgame, so every code that grants them is valuable.
Official Investigator Logs (2-10 per code): The lower-tier version used for early character leveling. Still useful for new players or when building multiple characters simultaneously.
W-Engine Power Supplies (3-10 per code): Essential materials for upgrading W-Engines (the game’s weapon system). These are surprisingly rare from normal gameplay.
W-Engine Energy Modules (3 per code): The higher-tier version needed for advanced W-Engine upgrades.
Bangboo Algorithm Modules (1-2 per code): Used to level up Bangboos, your helpful AI companions.
Crystallized Plating Agent (4-10 per code): Character ascension materials needed to break level caps.
Ether-related Materials (occasional): Specialized materials for specific upgrade paths.
Since codes primarily grant Polychrome, it’s worth understanding how the gacha system works so you can maximize your free currency:
Zenless Zone Zero uses a pity system where you’re guaranteed a S-Rank Agent or W-Engine after a certain number of pulls. The pity counter carries over between banners, so every pull brings you closer to your guaranteed character.
One pull costs 160 Polychrome or 1 Master Tape/Signal Search. A 10-pull costs 1,600 Polychrome. The guaranteed S-Rank pity is at 90 pulls for character banners.
Here’s where codes become powerful: If you collect codes consistently, you can save up for guaranteed characters without spending money. That 300 Polychrome from livestream codes equals almost 2 free pulls every six weeks. Over time, this adds up significantly.
I recommend saving all your Polychrome for characters you really want rather than pulling on every banner. Use the Anime Card Clash codes guide strategies if you enjoy similar gacha mechanics.
After redeeming hundreds of codes across multiple HoYoverse games, here are my best practices:
Create a Spreadsheet: Track which codes you’ve redeemed. It’s easy to forget, especially when codes have similar names like “ZZZ20NEWSEASON” and “ZZZ2NDSEASON.”
Enable Push Notifications: Turn on notifications for the official X/Twitter account (@ZZZ_EN) so you’re alerted the moment livestream codes drop.
Join the Discord: The official Zenless Zone Zero Discord often shares codes faster than other platforms. Plus, community members quickly report when codes expire.
Redeem During Off-Peak Hours: Some codes have usage limits. If you redeem during peak hours right after a livestream, you might miss out if the code hits its redemption cap.
Check Multiple Sources: Different regions sometimes get exclusive codes. Following both English and Japanese official accounts can occasionally net you extra codes.
Save Screenshots: Take screenshots of your redemption confirmations. If there’s ever a technical issue, you’ll have proof you redeemed the code.
With the November 14 livestream approaching, here’s what we know about the upcoming update:
The Version 2.4 update releases on November 26, 2025 and will feature two new S-Rank Agents: Dialyn (Physical attribute, Stun specialty) and Banyue (Fire attribute, Rupture specialist). Both belong to the mysterious Krampus Compliance Authority faction.
The update concludes Season 2’s main story, bringing us to the climax of the current narrative arc. Expect new story missions, events, and possibly new gameplay features.
During the livestream, you can expect at least one code worth 300 Polychrome. Based on HoYoverse’s pattern, they might also announce special celebration codes or social media event codes.
If you’re interested in other action RPGs with similar character collection mechanics, check out our Cookie Run Kingdom codes guide for another great mobile game with regular code releases.
While codes are fantastic, you shouldn’t rely on them exclusively. Here are the best methods to earn Polychrome through regular gameplay:
Daily Errands: Complete simple daily tasks for up to 60 Polychrome per day. This is the most consistent source of premium currency.
Combat Commissions: Story and combat commissions award Polychrome as completion rewards. Prioritize these whenever new ones appear.
Events: Limited-time events like Officer Mewmew challenges and Shiyu Defense stages grant Polychrome bonuses.
Exploration: The Compendium Trials and exploration objectives in each zone provide one-time Polychrome rewards.
Audition Stage: Testing S-Rank Agents from current banners actually rewards you with Polychrome. This is a unique feature that encourages you to try before you pull.
Achievements: Long-term achievements related to combat, exploration, and collection grant substantial Polychrome rewards.
Combining these methods with regular code redemptions can net you thousands of free Polychrome per update cycle. For comparison with similar games, our Anime Rangers guide shows how different games approach free currency distribution.

Remember to follow all these channels and enable notifications so you’re immediately aware when new codes drop.
New codes are released primarily during Special Program livestreams, which occur every six weeks alongside major version updates. Additionally, HoYoverse occasionally releases codes for social media events, holidays, and special milestones. The most reliable schedule is the livestream cycle—expect a guaranteed code worth 300 Polychrome every update.
Yes, you can redeem the same code on different accounts as long as each account meets the requirements (Inter-Knot Level 5 and completed prologue). However, you can only redeem each code once per account. This is useful if you’re maintaining multiple accounts for rerolling purposes.
Yes, most codes have expiration dates or usage limits. Livestream codes typically expire within 24 hours of announcement, making them extremely time-sensitive. Some permanent codes remain active indefinitely, but these are rare. Always redeem codes as soon as you see them to avoid missing out.
The most common reasons are expired codes, incorrect capitalization, typos, or not meeting the level requirements. Codes are case-sensitive, so “ZZZ23SWEETILY” is different from “zzz23sweetily.” Additionally, some codes are region-specific and may not work on all servers. Double-check that you’ve entered the code exactly as shown and that your account is eligible.
Code rewards sent to your mailbox expire after 30 days if unclaimed. Make it a habit to check your mailbox regularly and claim all rewards immediately. Set a reminder if you’re worried about forgetting, especially if you’ve redeemed multiple codes at once.
No, Zenless Zone Zero codes work across all platforms (PC, PlayStation 5, Xbox Series X|S, mobile). The codes are tied to your HoYoverse account, not your platform. However, you must redeem them through the appropriate method for your platform (in-game or website).
Unfortunately no. The code redemption feature is locked until you complete the “Business x Strangeness x Justness” prologue quest and reach Inter-Knot Level 5. This takes approximately 30-45 minutes of focused gameplay. Once unlocked, the redemption feature remains available permanently.
I recommend saving your Polychrome for limited S-Rank characters you really want rather than spending it immediately. Focus on characters that fit your playstyle or team composition. Avoid pulling on standard banners since you’ll eventually get those characters through regular gameplay. The limited character banners offer exclusive Agents you can’t obtain anywhere else.
The pity system guarantees a S-Rank Agent after 90 pulls on the limited character banner. Since each pull costs 160 Polychrome, you need 14,400 Polychrome for a guaranteed S-Rank. This is why collecting every code is so important—they significantly reduce the time needed to save for your desired character.
No, once a code expires or reaches its usage limit, it becomes permanently invalid. HoYoverse doesn’t typically reactivate old codes. This is why immediate redemption is crucial, especially for livestream codes with 24-hour expiration windows.
Zenless Zone Zero codes are an essential resource for any player looking to build their roster without spending money. By following this guide and redeeming codes consistently, you can accumulate thousands of free Polychrome over time. Remember to bookmark this page and check back regularly—I update it immediately whenever new codes are announced.
The November 14, 2025 livestream for Version 2.4 is right around the corner, so set your reminders now. Those 300 Polychrome won’t claim themselves, and you don’t want to miss out on one of the most valuable code releases of the update cycle.
Stay connected with the official Zenless Zone Zero channels, complete your daily tasks, and always redeem codes as soon as they’re announced. With patience and consistency, you can build a powerful team without spending a single dollar. Good luck, Proxy, and may your pulls be blessed!
