Polychrome is the premium currency in Zenless Zone Zero, and every serious player needs a reliable plan to keep stacking it. With every limited banner demanding up to 14,400 Polychrome for a guaranteed pull, knowing exactly where to farm makes the difference between hitting your target and falling short. Whether you're a casual player logging in for dailies or a dedicated one grinding endgame content, these are every free Polychrome source in ZZZ broken down by frequency — no filler, no fluff.
Quick Tip: Consistent daily and weekly farming adds up faster than most players expect — and if you ever need to top up, LootBar has you covered on ZZZ Top up.
What Is Polychrome Used For?
Polychrome powers your Signal Searches (gacha pulls), with each pull costing 160 Polychrome. Hitting the 90-pull pity on a limited banner costs 14,400 Polychrome, so consistent farming isn't optional — it's essential.

Daily Polychrome Sources
Daily Errands
Your most reliable baseline. Complete simple tasks — buying coffee, scratching cards, interacting with the video store — and you'll collect 60 Polychrome every day through engagement point milestones. That's 1,800 Polychrome per month just for a 10–15 minute routine, most of which can be done without ever leaving Sixth Street.
Daily Errands
Howl's News Stand
Easy to overlook but worth visiting every day. The Lucky Scratch Card gives a guaranteed 20–60 Polychrome on days 3, 8, 15, 20, and 27 of the month, with a 6% chance for 10 Polychrome on other days. Small odds, but it's completely free.

Weekly Polychrome Sources
Shiyu Defense
The highest-value recurring source in the game. The Critical Node awards 720 Polychrome per completion and resets every 14 days, giving you 1,440 Polychrome monthly. You'll need two solid teams built for the dual-battle format — but no endgame mode pays out better on a consistent basis.
Shiyu Defense
Shiyu Defense Levels
Deadly Assault
A rotating mode where you challenge three high-difficulty bosses. Polychrome rewards scale with the stars you earn, and it resets on the same 2-week cycle as Shiyu Defense. Build two strong single-target teams and clear it every rotation.
Deadly Assult
Deadly Assult Levels
Hollow Zero
(including Lost Void, Withered Domain, and Arpeggio Fault) contributes around 960 Polychrome over six weeks through weekly objectives, license level milestones, and exploration logs. Lost Void in particular offers some of the best free-to-play value in the game — the license level rewards are substantial and the mode is genuinely fun to grind.
Hollow Zero
Hollow Zero Rewards
Endless Tower (Simulated Battle Trials)
Rewards Polychrome at specific floor milestones. It's a permanent mode with a damage-stacking mechanic — once your characters take hits, the effects are permanent for that run — but the Polychrome tied to progression floors makes it worth clearing consistently.
Simulated Battle Trials
Weekly Errands and Ridu Activities
Reset every week and offer smaller but steady rewards. The weekly format runs on a bingo-style structure — knock out your dailies and the small extra tasks and you'll clear it within three or four days without any extra effort.
Weekly Errands
One-Time but Significant Sources
These don't reset, but they add up fast — especially for newer or returning players.
Achievements
One of the largest hidden Polychrome pools in the game. With 558 total achievements rewarding up to 3,975 Polychrome combined (5 for Bronze, 10 for Silver, 20 for Gold), there's always something within reach — whether it's combat milestones, exploration, story progression, or Arcade minigames.
Achievements
Story and Commissions
Reward Polychrome on first-time clears through the HDD system. Side commissions are worth hunting down too — some are hidden behind NPC interactions or specific zone triggers that most players miss entirely.
Story
Agent Stories
Grant a one-time Polychrome bonus per character. They're easy to skip, but every chapter cleared is free currency left on the table.
Agent Story
Agent Demos
Reward 20 Polychrome per first-time completion for both standard and limited banner characters. Run every trial when a new banner drops — it takes minutes and adds up patch over patch.
Agent Demo
Inter-Knot Level Rewards
Pay out 200 Polychrome at levels 3, 13, 23, 33, 43, and 53, for a total of 1,200 Polychrome over time.
Inter-knot Level Rewards
Proxy Primer / Compendium Rewards
One-time milestone rewards unlocked through the main story. Complete the challenges across each Primer for Polychrome, Master Tapes, and W-Engines.

Redemption Codes
Drop during every major ZZZ livestream and typically expire within 24 hours. Follow official channels and community Discord servers to catch them in time.
Maintenance Compensation
Sent to your in-game mail every patch downtime — usually 300 Polychrome just for logging in after the update.
Limited-Time Events
The single largest per-patch source outside of endgame modes. Major events routinely offer 1,000–1,500 Polychrome across quest completions, mini-games, and milestones. Always prioritize these before they expire.
Limited Time Events

Bonus Tips to Maximize Your Polychrome
- Never spend Polychrome on Battery Charge refills. Natural stamina regeneration is free — save every drop for gacha pulls.
- Always pull on limited banners, not standard ones. The New Eridu City Fund and weekly sources give standard pulls for free over time.
- Check for Redemption Codes after every livestream. They expire fast, sometimes within 24 hours.
- Do Agent Demos the moment a new banner drops. It's 20 free Polychrome per character that most players forget entirely.
- Chase Gold achievements when you're close. Each one pays out 20 Polychrome — hunt them in batches rather than leaving them unfinished.
Conclusion
Farming free Polychrome in Zenless Zone Zero is a long game, but the sources are consistent once you know where to look. Stack your dailies, clear every endgame rotation, and never let a limited-time event expire without completing it. The players who stay ahead on banners aren't necessarily spending more — they're just not missing anything. Stick to this routine every patch and watch your Polychrome reserves steadily climb.
And if you're looking to top up and push even further, you can also consider using LootBar to top up Zenless Zone Zero.
