Nothing Uncanny: Lateral Thinking Puzzles

How to start

1. Open it in your AI. Tap Open in ChatGPT or Open in Claude and press send, or paste the play prompt into any assistant that can open links. The chat must be able to open a link, because the Editor reads a sealed file.
2. The casebook loads. The Editor loads the six cases and their sealed file, reads you the start of the SHA-256 commitment, and opens Case 1.
3. Ask, then solve. Ask yes/no questions about what happened, then type Solve: and tell the story. Fewer questions and hints score more.
4. Check it afterwards. Check the seal at aigamecards.com/verify, and check every ruling against the sealed file.

Questions

Can ChatGPT host lateral thinking puzzles?

Not reliably on its own. A chat with no fixed story has nothing to answer from, so it improvises, contradicts itself across thirty questions, or accepts any explanation that sounds right. This card gives it a fixed story. Each case's story, the facts that settle the usual yes-or-no questions, and the points a solve must state are locked under SHA-256 before play. The host fetches that file at load and rules from it, and a case counts as solved only when you have stated every point. After the game you can check every ruling against the file.

What does the seal prove, and what doesn't it?

It proves that the six stories, their facts, key points and hints were fixed before your first question; you can rebuild the hash at aigamecards.com/verify. It does not prove that every ruling was right. The host can misread a fact, so the whole file is yours to read after the game, with your notes beside it.

How long does it take, and can a group play?

Six cases, about ten to twenty minutes each: roughly an hour and a half for the casebook, and longer with a group thinking aloud. One to six people can play at one screen. One types, everyone asks, and the question count is shared; the cases open in order. When a case closes, the Editor reads its full answer. You can save between cases and carry on in a new chat. It is the same yes-or-no format as the albatross soup puzzle, with six stories written for this card.

Is it suitable for teenagers or a class?

It is rated 12+. The cases involve deaths and crimes, told plainly. Nothing is gory, nothing supernatural happens, and no child comes to harm. The column and all six cases are invented. With an adult at the keyboard it suits teenagers as well as adults, and it asks for no personal details.

Does the chat have to be able to open a link?

Yes. The Editor fetches the sealed file from aigamecards.com at load, and pasting it yourself would show you all six answers. If the file will not open, the game does not start. aigamecards.com/launch-matrix lists which apps can currently open links. The card itself is free.
