Polychrome is the most important currency in Zenless Zone Zero. You need it to pull for new characters and W-Engines from the gacha banners. Every pull costs 160 Polychromes, and getting an S-Rank character can take up to 90 pulls on limited banners. In the worst case, you might need 180 pulls to guarantee the featured character you want.
Don’t want to put in the daily effort of grinding Polychromes? Then worry not and head over to U7BUY where you can buy zzz monochromes and polychromes at the cheapest prices you can imagine. They’re the most trustworthy site out there!
Daily and Weekly Sources
The most reliable way to earn Polychrome is through activities that reset regularly. These should be your top priority every day.
Daily Errands
Polychromes are earned most efficiently through the Daily Errands. If you farm the daily quests everyday, you can get 60 Polychromes easily. The errands reset daily and take around 10 minutes to finish, so they can be done pretty fast. This will add up to 1,800 Polychromes per month.
Shiyu Defense
This is a mode that will give you the highest amount of Polychrome. Shiyu Defense resets twice a month and you can earn up to 720 Polychromes if you get an S-Rank completion throughout the 7 levels. And if you finish them both times in the month, you can earn up to 1,440 Polychromes.
This mode requires two strong teams because you need to complete dual battles. Focus on building characters that can handle the time limits and enemy waves efficiently.
Hollow Zero
Hollow Zero works like other HoYoverse endgame modes. You can earn about 960 Polychromes over 6 weeks through weekly bounties. Each first-time clear of new areas also rewards around 80 Polychromes.
The Investigation License provides 40 Polychromes per level as you advance from Level 1 to 60, totaling 1,000 Polychromes. You can clear these stages even without fully built characters, making it accessible for newer players.
Story and Exploration
Playing through the main story rewards Polychrome at every step. Story Commissions give you set amounts of Polychrome, with bonus rewards for completing objectives within time limits.
Side quests reward Polychrome, so don’t skip them. Look for Missing Mini Cargo Trucks (chests) while exploring New Eridu. These give Polychrome and other items.
Ridu Journey Mini Achievements are easy to complete since most just require walking around New Eridu. Perfect for casual farming sessions.
Events and Limited Content
Zenless Zone Zero regularly features limited-time events that offer large amounts of Polychrome. Check the event menu frequently and complete all available challenges. Events can give you 500 to 1,000 Polychromes depending on their scope.
Version updates typically bring new events with fresh Polychrome rewards. Version 2.0, for example, offered over 22,680 Polychromes through various sources.
Character Trials
Every S-Rank character features trials called Character Auditions. These let you test characters before pulling for them. Each Character Audition rewards 20 Polychromes upon completion. Permanent trials stay forever, while limited trials change with each banner rotation.
Achievements and Mini-Games
The achievement system contains hundreds of tasks that reward Polychrome. You can earn 5, 10, or 20 Polychromes per achievement depending on difficulty. Claim these rewards from the main menu regularly.
The Sixth Street arcade offers excellent Polychrome farming outside main content. Games like Snake Duel, Soul Hounds III, and God Finger have achievement systems. Each mini-game has numerous achievements that reward Polychrome, totaling 350 Polychromes or more.
Other Sources
- Officer Mewmew Missions: Complete tasks across six locations (Brant Street Construction Site, Ballet Twins Road, Blazewood, Port Elpis, Sixth Street, and Lumina Square). Each task rewards 10 Polychromes.
- Daily Scratch Cards: Visit Howl’s News Stand on Sixth Street for Lucky Scratch Card rewards. Avoid waking Howl up late in the evening for better chances.

Monthly Income Breakdown
Here’s what free-to-play players can expect each month:
| Source | Monthly Polychrome |
| Daily Errands | 1,800 |
| Shiyu Defense | 1,440 |
| Hollow Zero | 640 |
| Events | 500-1,000 |
| Achievements | 100-300 |
| Total | 4,480-5,180 |
This gives you 25 to 31 pulls per month. To guarantee a featured character, you’ll need to save for 6 to 7 months as a free-to-play player.
Final Tips
Focus on consistency rather than trying to get everything at once. Complete your Daily Errands every day since they provide the most reliable income. Don’t ignore exploration and achievements because they add up over time.
Build two strong teams early to tackle Shiyu Defense efficiently. This mode offers the best rewards and resets twice monthly.
Participate in every limited event for the best value. Save your Polychromes for characters you really want instead of pulling on every banner.
