Michal Kamm has accused Hoyoverse of copying elements from his 2024 game Ouros for a minigame in Zenless Zone Zero. He shared a video on Bluesky highlighting the similarities.
Kamm released Ouros in 2024. The Zenless Zone Zero minigame appeared in a limited-time event last year. Both involve manipulating a track to guide a ball through numbered targets in various configurations, along with shared features like portals, a reverse direction button, and a hint system for the track shape.
