What Chinesecheckers is for

"How does a chain jump actually work?", "is Chinese Checkers actually Chinese?", "how do you set up a 3-player game?", "what's a good opening strategy?" — a hand-curated, original-language reference for Chinese Checkers (Sternhalma) and its cross-and-circle / peg-jumping board-game relatives, written to answer with real detail, not a vague description.

What it does

rule_lookup gives one rule topic's full detail — board layout, movement, jumping, chain jumps, home and target triangles, passing through other players' areas, turn order, illegal moves, and common house rules — or lists every topic with a summary if none is given. term_glossary defines board-game terms such as bridge marble, hop chain, hexagram board, center field, and cross-and-circle game. variant_info describes a named board-geometry relative — Sternhalma / standard Chinese Checkers itself, its square-board ancestor Halma, the two-player long game, super/big-board editions, and the separate cross-and-circle family (Pachisi, Ludo, Parcheesi, Sorry!, Aggravation, Mensch ärgere Dich nicht) — and explains exactly how each one relates to Chinese Checkers rather than just naming it. strategy_concept explains a named strategic idea, from spotting jump chains and leaving bridge marbles to endgame turn-counting and knowing when blocking isn't worth it. player_count_setup gives the home/target triangle layout for 1 (solo practice), 2, 3, 4, or 6 players, including an honest note that 4-player setups are less standardized than the rest. beginner_tips gives a ranked shortlist of the most useful tips for a new player. history_note covers the game's real, well-documented origin. scoring_summary explains how winning and finishing order work, since the game keeps no move-by-move score.

What it is not

Not an official rulebook and not a reproduction of any single publisher's printed rules — small house-rule variations are common in this game (most often whether a marble may leave the target triangle once it arrives), and this reference says so plainly rather than presenting one house rule as universal. It also is not a live matchmaking or scoring service — there is no gameplay engine here, just a reference you can look things up in.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Chinesecheckers — Privacy Policy

Effective 25 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Chinesecheckers is. Chinesecheckers is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for a hand-curated, fully local Chinese Checkers and cross-and-circle race-game reference — rules, jump-chain mechanics, a glossary, board-geometry relatives, strategy concepts, player-count setups, beginner tips, a history note, and a scoring explainer. You interact with your assistant; the assistant sends us only the arguments needed for that one lookup.

What we receive. The arguments of each tool call — a rule topic, a glossary term, a variant or strategy name, or a player count — 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 answered from a bundled, hand-curated reference file and nothing is stored. No request is forwarded to any third party — there is no upstream call at all, live or otherwise — and no query is logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant or your name, and we do not build a profile from your queries: each request is answered independently 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 — the entire dataset is bundled with the server and answered locally. 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 and do not use your data to train models.

Children. Chinesecheckers is a general-audience service operated by the adult using the assistant.

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

Chinesecheckers — Terms of Service

Effective 25 September 2026. These terms govern use of the Chinesecheckers connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Chinesecheckers returns a hand-curated, fully local Chinese Checkers (Sternhalma) and cross-and-circle race-game reference — rules, jump-chain mechanics, a glossary, board-geometry relatives, strategy concepts, player-count setups, beginner tips, a history note, and a scoring explainer. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Reference, not an official rulebook. Content is original commentary describing widely known, general Chinese Checkers practice, not a reproduction of any one publisher's printed rules. Small house-rule variations exist for this game (most notably whether a marble may leave the target triangle once it arrives); where your own board's rules differ from this reference, your board's rules govern your game.
3. Historical and factual claims. Historical notes (such as the game's origin as Sternhalma) reflect generally accepted, well-documented information as of the Service's stated build date; exact early commercial dates can vary slightly between sources.
4. Acceptable use. Automated use within the published rate limits is welcome.
5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
6. Data. Our Privacy Policy describes what we process. In short: your query is answered from a bundled reference file, and nothing is stored.
7. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
8. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss, injury, or damage arising from use of, or reliance on, the Service. Our total liability is limited to US $100.
9. Governing law. California law; venue in San Mateo County, California.
