2. How to play D&D with an AI dungeon master

   Running D&D or any tabletop RPG in ChatGPT, Claude or Gemini: why an open prompt drifts, and what keeps an AI game master consistent.

3. AI murder mystery games that can't cheat

   How a SHA-256 sealed solution stops the AI retrofitting the ending, and how to verify it yourself.

4. How to save and resume an AI game

   Take a plain-text save code and resume in any assistant, even a different one.

5. Can ChatGPT play chess yet? An honest answer

   What a 2026 benchmark found, why language models still lose the board, and what AI chess is actually good at.

Games by kind

• D&D-style RPGs Original role-playing systems and campaigns your AI runs as game master. 4 games.

• Chess puzzles & trainers Fixed-answer puzzles and honest trainers — what AI is actually good at. 2 games.

• Escape rooms Locked rooms you read your way out of before the timer — the final code sealed so the room can't move it. 2 games.
• Word games Sealed word games — every answer is committed before the first card turns, so the AI can check you, never move it. 3 games.
• Text adventures Parser-style adventures with a fixed map and a real inventory — the door your AI describes is the door that's actually there. 2 games.
• Survival games Ration what you carry against a clock that doesn't negotiate — the hazards are dealt from a published tape, not chosen to spare you. 3 games.
• Logic puzzles Deduction with one provable answer, sealed before release — the AI checks your reasoning instead of grading it kindly. 2 games.

• Riddles & lateral thinking puzzles Riddles and yes/no mysteries whose answers are sealed before you guess — the AI rules from the file, not from whatever sounds plausible. 2 games.
• Guessing games & 20 questions Guessing games whose answer is fixed before your first question — the AI answers from a sealed card, not from whatever fits your last guess. 2 games.
• Strategy & simulation games A kingdom to rule and a life to live, every effect printed and every event dealt from a dice tape published before you start — the AI looks things up instead of making them up. 2 games.
