There is no support ticket system here — just people who built the games. Email reaches us fastest.

We read everything. Because there is no account system, please describe what you were doing — including the game room code if you were in a match — so we can reproduce it.
What to send us
- Bugs: which game, what mode, what you clicked, and what went wrong. A screenshot helps enormously.
- Device info: browser and OS, especially on mobile — touch targets and keyboard-only navigation are the two things we care about most.
- Accessibility issues: anything that blocks keyboard, screen reader, or reduced-motion use.
- Partnerships / press: put the word "partnership" in the subject line.
Things we cannot do
We do not have player accounts, so we cannot recover progress stored in a browser you have cleared. We also cannot remove skill ratings or match history from an ongoing ranked pool on request — scores reset on their own with the weekly cycle.
