Description

From the marketplace listing

Alibi Hour is a daily whodunit you solve in ChatGPT. Every day everyone gets the same case: something has gone missing (a trophy, a cake, a robot's chip), four suspects, a map of four rooms and six ten-minute times. One suspect is the culprit and lies in every answer; the other three always tell the truth. The culprit was alone at the scene at the minute it happened. Ask a suspect where they were at a time, for example "Ask Ben where he was at 8:30", or tap a square on the timeline in the card. Each question gets one answer, word for word. You have 10 questions. Look for the story that can't be true: two answers that clash, or someone crossing the house faster than anyone can walk. Then accuse. Every case is checked by a solver before it opens: exactly one suspect can be the culprit, and par is the fewest questions that prove it. When you accuse, you see whether your own answers proved it, par, where everyone really was, and how your result compares with everyone who played that day. Your solving streak grows each day you get it right, and you can share your result without spoiling the answer. Party mode turns a case into a game for friends in one room. Say "Start an Alibi Hour mystery party": guests open the link on their phones, up to four take a suspect's private sheet with the lines to answer, and the rest play detective. Everyone votes on their own phone, and the card reveals who did it. The culprit is known only to Alibi Hour and to the guest playing them, so the host plays too. Limits: - One daily case for everyone. A new case opens at 00:00 UTC; Monday and Tuesday are easy, Friday to Sunday hard. - English only. - Cases are fiction and non-violent: things go missing or get pranked, and nobody is hurt. - No accounts: Alibi Hour keeps your questions and streak under ChatGPT's anonymous user ID. Say "Delete my Alibi Hour data" to delete them. - ChatGPT never receives a statement you didn't ask for, or the culprit, before you accuse. - Parties are deleted 24 hours after their last activity.
