How to Participate: Step-by-Step
Participating is easy. Follow these steps to get started.
1. Find Your Invite Code
Log in to the Assembly Commission: Return to Ridu webpage. You will see a unique invite code. Copy this code. This is your most important tool.
2. Share with Friends
Send your code to friends who have not played ZZZ for a while. To count as a "Returning Proxy," they usually must have been inactive for at least 14 days and reached a certain Inter-Knot level (check the specific rules on the page).
3. Link and Earn
When your friend enters your code on their screen, you both get rewarded. You get an instant 60 Polychromes. They get a "Returner's Gift" to help them catch up.
4. Complete Challenges
The event has "Assembly Commission" challenges. These usually involve your friends completing daily tasks or spending Battery Charge. As they play, you earn progress toward the 740 Polychrome total. This will be the easiest way to earn some free polychrome in Zenless Zone Zero.
Strategic Tips: How to Find Returners

Finding people to use your code can be hard. Here is how the pros do it.
- Check Your Socials: Post your code on X (Twitter), Reddit, or Discord. Many players look for codes to get their own returner rewards.
- Be Helpful: Don't just post the link. Explain that they get free rewards for using it. People are more likely to help if they benefit too.
- Use Official Channels: Join the Zenless Zone Zero Official Discord. There is often a dedicated channel for the Assembly Commission event.
