Play twenty questions with an AI, right in the chat
Guess what the agent is thinking of in 20 yes or no questions.
How it plays
The Agent thinks of a thing and locks it in as a secret. Ask yes or no questions; each one counts. Guess it within 20 to win. The secret is revealed at the end, so you can see the answer never changed.
Start a game
Once Playtable is connected, say:
Let's play twenty questions on Playtable.A board shows up in the chat. Click to make your move; the AI takes its turn. Want different rules? Just say so: "same thing but on a bigger board" works.
Set it up once
Playtable is a connector. Add it once and any chat can start a game.
https://play.rowhousesoftware.com/mcp- Claude (web, desktop or phone): Settings, then Connectors, then Add custom connector. Paste the link above and name it Playtable. Free plans can add one custom connector.
- ChatGPT: Settings, then Apps, then Advanced, and turn on Developer mode. Then create an app with the link above. Developer mode needs a paid plan right now.
- Anything else that speaks MCP, like Cursor or VS Code: add a remote server with the link above. No key needed.
Then just ask: "Let's play checkers" or "Make up a card game for two and deal me in."
