MatrixMind is run by one person, so replies are not instant — but every message is read.
What to write about
- A puzzle that seems wrong, or has more than one defensible answer
- Anything broken — a mode that will not load, progress that vanished
- A game in The Vault that no longer works
- Questions about how data is handled — see the Privacy Policy first, it is short
- If you own a game embedded in The Vault and would rather it were not, say so and it will be removed
Lost progress? Worth knowing before you write: your rating and
history live in your own browser, not on a server. Clearing site data, or
switching browser or device, means starting fresh — and there is no backup we
can restore from. That is the trade for having no accounts.
