Contact Coreball Online
CoreBall is maintained by a small team, so we read every message. Email is the fastest way to reach us.
What We Can Help With
- Bug reports — tell us the level number, your browser and device, and what happened.
- Level or content feedback — if a layout feels unfair or a page is unclear.
- Accessibility issues — anything that makes the game harder to use with a keyboard, screen reader or zoom.
- Advertising and partnerships — questions about the ad slots on this site.
- Corrections — if something we wrote about the game or its technology is wrong.
Before You Write
Many questions are already answered in the FAQ, the How to Play guide, or the levels page. The game needs no account, so we cannot recover progress that was cleared from your browser storage.
Response Time
We aim to reply within a few business days. Abuse reports and broken-level reports are prioritised.
