QED Night is operated by Cassau LLC. Email [email protected] and a person reads it. There is no support queue and no bot in front of it.
A game that misbehaves
Use the ⚑ button under the game, or email the game's address and what happened. A game from another studio that three players report goes back to review straight away.
A puzzle that doesn't check out
This is the one we most want to hear about. A puzzle carrying the ∎ mark has been checked so that exactly one answer fits, so a puzzle with no solution, or with two, means the check failed and we need to know.
Send the puzzle's URL and, if you have it, the answer you found. That is enough to reproduce it.
Bugs and account problems
Include the page URL, what you expected, and what happened instead. If it involves your account, say which email address it is registered under. Never send your password.
Privacy and data requests
Requests to see, correct, or delete the data held about you go to the same address. What is collected and how long it is kept is set out in the Privacy Policy.
