If the card or its sealed file won't open, don't start without them: tell me this game needs a chat that can open links. Be the game master and begin.",

      "q": "Can ChatGPT host a trivia night?",
      "a": "It can play game show host, but plain chat can make answers up and stick to them, and in voice mode it has given answers away while children were still thinking: one family's football quiz got an invented hat-trick, an \"I'm sure!\", and answers read out before the children could discuss them. Here every answer, the other forms it accepts, the near misses it refuses and a source for each were sealed under a SHA-256 hash before release. The card tells the host to rule only from that key, to name the source with every ruling, to answer no question from its own knowledge, and to rule on nothing until every team has answered. The seal shows the key did not move; it cannot show that every ruling was right."
    },
    {
      "q": "What does the seal prove, and what doesn't it?",
      "a": "It proves the answer key did not change: its SHA-256 hash was published before release, and after the night you can rebuild it from the revealed key at aigamecards.com/verify. It does not prove the host ruled every answer correctly, so each ruling names the key's answer and its source for you to check, and the card tells the host to correct any ruling that misapplied the key. The key is a public file: it is fixed before play and checkable after, not hidden from a player who goes looking for it."
    },
    {
      "q": "How long is it, and how many can play?",
      "a": "Twenty to forty-five minutes for 25 questions. Play solo, or as two to four teams of any size at one screen. Every team answers every question, written down first and sent together in one message, so no team sits out a turn. A tie at the top goes to the Candle-End: up to two sealed questions with a year for an answer, closest wins. Say \"save\" between questions for a code that resumes the night in a new chat."
    },
    {
      "q": "Is it a good family Halloween quiz for children and classrooms?",
      "a": "The content suits all ages: Halloween customs, festivals around the world, classic books, bats, owls and spiders, and sweets, with nothing gory. Difficulty is another matter. The one-pointers suit primary-school children, several five-pointers are hard for adults, and about a third of the points are on British and Irish customs, so the host suggests mixing ages on every team. Teams play as Bats, Ghosts, Owls and Toads, so the game never asks for anyone's name. It assumes an adult at the keyboard."
    },
    {
      "q": "Does the chat have to open a link, and can we play by voice?",
      "a": "It has to open a link. The host fetches the sealed key from aigamecards.com when the night starts; pasting it in yourself would show you every answer. Not every app can, and it changes; aigamecards.com/launch-matrix shows which currently do. Start the night by typing. Once the key is loaded you can switch to voice in the same chat if your app allows it, with one adult speaking the teams' written answers. No account beyond the chat app you already use, and nothing to buy."
