One person hosts a lateral thinking mystery using their phone. Read the solution and host guide, then answer your friends’ spoken questions. No AI judging or ads in this mode.
Choose Play together in the collection. One person is the host and operates their own phone. Everyone else asks questions aloud. Solo play and its saved records remain available.
The host chooses a mystery and privately opens the solution and host guide. Hide the guide before showing the phone to other players, then read the story aloud.
Use the guide to answer Yes or No. Say Not relevant for details unrelated to the explanation, or Not specified if the story does not establish a fact. Spoken questions and answers are not recorded or sent.
Accept an explanation when it connects the key events, even if the wording differs. The host can offer gentle hints when the group gets stuck. This mode uses no AI judging and displays no ads.
