About

Pyramid Solitaire is a real, stateless, playable single-player card game. new_game deals a genuine 28-card, 7-row pyramid plus a 24-card stock. remove_pair removes two currently-selectable cards (pyramid cells and/or the waste top) whose ranks sum to exactly 13; remove_king removes a lone King, never paired. A card is selectable only once both cards resting on it are gone. draw moves one card from the stock to the waste. get_valid_moves lists every legal move, and hint returns a real suggested move or a genuine no-more-moves report -- a stuck state only when no pair or King removal exists anywhere and the stock and waste are both empty. Keyless; fully local; zero upstream calls; nothing stored.

What Pyramid 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 28-card, 7-row pyramid and enforces the real coverage and pairing rules.

What it does

new_game shuffles a real 52-card deck and deals the standard pyramid: row 0 has 1 card at the top, row 6 has 7 cards at the base (28 cards total), with the remaining 24 forming a draw-1 stock/waste. A card is selectable only once the two cards resting on it in the row below are both gone (the base row starts selectable). remove_pair(state, a, b) removes two selectable cards (pyramid cells and/or the current waste-top card) whose ranks sum to exactly 13 (A=1 ... Q=12); remove_king(state, target) removes a single King (rank 13) alone — a King is never paired. draw moves one card from the stock to the waste (recycling the waste back into the stock once the stock empties). The game is won once all 28 pyramid cards are gone. get_valid_moves lists every legal move, and hint returns a real move or a genuine no_more_moves report — a card is only "stuck" when no pair or King removal exists anywhere AND the stock and waste are both empty.

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). Pyramid is single-player, so there is no secrecy concern.

What it is not

Pyramid 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

Pyramid Solitaire — Privacy Policy

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

What Pyramid Solitaire is. Pyramid 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 pyramid, 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. Pyramid Solitaire is a general-audience service operated by the person using the assistant.

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