Play twenty-one with an AI, right in the chat
Get closer to 21 than the dealer without going over.
How it plays
Face cards count 10, aces 1 or 11. You are dealt two cards; draw more to get close to 21 without going over, then end your turn. The dealer (Agent) then draws until reaching 17 or more. Closer to 21 wins; over 21 loses. Agent: deal by drawing two cards to each hand, deal yourself from the deck, and score rounds with the wins counter. Use collect to reshuffle between rounds.
Start a game
Once Playtable is connected, say:
Let's play twenty-one 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."
