A shot worth choosing.
Z Ball: 1v1 Star Cluster UNC is Zyntra’s physics-based ball game for Android. Pull back to choose angle and power, release, and read the position left on the table. Bank shots, collisions and direct-link scoring turn a simple gesture into a planning decision.
It is our independent digital interpretation of the sloped-table format viewers may know as Star Cluster Ball or UNC Ball, with its own arenas, rules and progression.

Describe the inspiration accurately.
Star Cluster Ball, UNC Ball and the source-verified Chinese name 星罗球 (Xing Luo Qiu) help identify the physical sloped-table format. They are context for our game’s inspiration, not official alternate product names for Z Ball. Different physical tables and published guides can use different scoring systems.
Zyntra is not affiliated with or endorsed by UNC-BALL, YoTyan or the physical-sport brands and channels. Z Ball has its own rules. Our game’s 1 / 2 / 5 rows should not be presented as the universal rules of the physical sport.
