About

Blackjack Trainer is a real, stateless, playable blackjack engine. new_round shuffles a fresh multi-deck shoe and deals two cards each to player and dealer (one hidden). get_valid_moves lists legal actions for a hand. make_move applies hit, stand, double, or split and returns the new state. dealer_play reveals the hole card, plays the dealer's hand under a fixed house rule (hits soft 17, stands hard 17+), and settles win/lose/push/blackjack payouts. render draws a human-readable table. basic_strategy_advice returns the mathematically standard action for any hand against a dealer up-card from a real decision table covering hard totals, soft totals, and every pair. There is no server-side session; every tool call takes the full game state and returns the new one. Keyless; fully local; zero upstream calls; nothing stored.

Sources: Original, hand-authored content. Fully local, zero upstream calls.

What Blackjack Trainer is for

A real, playable blackjack engine your assistant can run right inside the conversation — not a rules explainer. It computes hand values correctly (aces as 1 or 11), validates every action, detects busts and naturals, runs a dealer bound to a fixed, documented house rule, and can tell you the mathematically correct play at any decision point.

What it does

new_round shuffles a fresh multi-deck shoe and deals two cards to the player and two to the dealer (one hidden). get_valid_moves lists which of hit/stand/double/split are legal for a hand right now. make_move applies one of them and returns the updated hand and status. Splitting a pair turns one hand into two, played in sequence. Once every hand is settled, dealer_play reveals the hole card and plays the dealer's hand out under the fixed rule below, then settles win/lose/ push/blackjack outcomes with payouts. render gives a human-readable table view at any point.

basic_strategy_advice is a genuine basic-strategy decision table — not a hunch — covering hard totals, soft totals, and every pair, for a multi-deck game where the dealer hits soft 17. Given a hand and the dealer's up-card, it returns the standard action and why.

House rules (fixed and documented)

Dealer hits on soft 17 (an ace-high 17) and stands on any hard 17 or higher. Blackjack pays 3:2. A double is a first-decision-only move: the bet doubles and exactly one more card is drawn. Splitting is allowed up to three times per round (four hands); split aces receive exactly one card each with no further action, per standard casino practice.

How state works

There is no server-side session. Every tool takes the full game state (shoe, hands, dealer cards, phase) and returns the new one — your assistant carries that object forward between calls.

What it is not

Not a real-money gambling service and not betting-strategy or bankroll advice — a correct game engine plus a standard basic-strategy reference, both fully local and stateless. Play responsibly; this is entertainment and practice, not financial advice.

Blackjack Trainer — Privacy Policy

Effective 27 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Blackjack Trainer is. Blackjack Trainer is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf to run a real blackjack game — dealing, move validation, dealer play, and a basic-strategy advisor. 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 (shoe, hands, dealer cards), a chosen action, or a hand and dealer up-card for strategy advice — 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. Blackjack Trainer is a general-audience entertainment and practice tool operated by the person using the assistant; it does not involve real money or real-money gambling.

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