About

Klondike Solitaire is a real, stateless, playable single-player card game. new_game deals a genuine shuffled hand (draw1 or draw3 mode, optional seed for reproducible deals). make_move (or the specific draw / move_tableau_to_tableau / move_waste_to_tableau / move_tableau_to_foundation / move_waste_to_foundation tools) validates and applies one move against the real rules: alternating-color descending tableau runs, King-only empty columns, and suit-sequenced foundations from the Ace. get_valid_moves lists every currently legal move. hint returns a real legal move or correctly reports a genuine deadlock. render gives a plain-text board view. Keyless; fully local; zero upstream calls; nothing stored.

What Klondike Solitaire is for

A real, playable single-player card game your assistant can run right inside the conversation — not a rules explainer. Deals a genuine shuffled 52-card hand and enforces the real rules of every move: tableau builds, foundation sequencing, stock/waste draws, and win detection.

What it does

new_game(draw_mode, seed) shuffles a real 52-card deck and deals standard Klondike: 7 tableau piles sized 1-7 (only the top card of each face up), remaining 24 cards to the stock. draw_mode is draw1 or draw3. make_move (or the specific draw / move_tableau_to_tableau / move_waste_to_tableau / move_tableau_to_foundation / move_waste_to_foundation tools) validates and applies one move against the real rules: the tableau builds down by alternating color, an empty tableau column accepts only a King, and foundations build up by suit starting from the Ace. get_valid_moves lists every currently legal move. hint returns a real legal move (foundation moves first) or correctly reports a genuine deadlock — no legal move anywhere, including no draw available. render gives a plain-text view of the whole board.

How state works

There is no server-side session. Every tool takes the full game state (a JSON object) and returns the new one — your assistant carries that object forward between calls. Cards are compact strings like "TH" (Ten of Hearts) or "KS" (King of Spades). Unlike a two-player game, Klondike is single-player, so there is no secrecy concern: the full state (including the stock's hidden order) is visible to the assistant the whole time, which is exactly what lets hint reason about it.

What it is not

Klondike is a generic, public-domain card game name — this is an original implementation of its well-known rules, not affiliated with any card game product or brand.

Privacy policy

Klondike Solitaire — Privacy Policy

Effective 28 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Klondike Solitaire is. Klondike Solitaire is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf to run a real, single-player card game — dealing, move validation, and win detection. You interact with your assistant; the assistant sends us only the arguments needed for one tool call at a time.

What we receive. The arguments of each tool call — a game state (the tableau, foundations, stock and waste), a requested move, or a seed value — plus the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one) and standard server logs.

Everything is computed locally and nothing is stored. There is no upstream call at all, no database, and no per-user session — every tool call is a pure function of the state it's given. Game states are not logged, recorded, or used to train anything, and nothing carries over between requests. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. None — everything runs locally on our server. Hosting: Vercel (United States regions).

Legal bases and your rights. Our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information.

Children. Klondike Solitaire is a general-audience service operated by the person using the assistant.

Changes. We will post changes here with a new effective date.
