AI Game Cards

Strategy & simulation game prompts for ChatGPT, Claude & Gemini

Updated

A kingdom to rule and a life to live, every effect printed and every event dealt from a dice tape published before you start — the AI looks things up instead of making them up. Free, no signup. Each game is a ready-to-play prompt (we call it a game card) that you open in your own AI assistant.

A strategy or simulation game with an AI works when every effect is printed and the events are dealt before you play. On these cards each choice's effect is on the page, the order of events comes from a dice tape published with the card, and a one-line ledger carries the state, so the assistant looks things up instead of inventing outcomes.

Can ChatGPT run a strategy game or a life simulator?

Not reliably from a typed prompt. Ask an assistant to run a kingdom or a life and it writes each event as it goes, plays your rivals as it likes and keeps the numbers in its head, so a bad choice can be quietly forgiven and the score means little. Chat memory, where it is switched on, can recall that you played; it does not fix the next event before it happens or carry the exact numbers into a new chat.

These cards put those jobs on the page. The Steward's Year prints all sixteen petitions, every writ and its exact effect on four dials, and two neighbours that move only by printed rules; you rule a small river kingdom for one year, and a dial at either extreme ends it. Haddow is a life simulator, five years a turn from age five to as far as ninety, in which you keep body, craft, kin and purse in balance and gather keepsakes. Both deal their events from a d20 tape seeded from the card's id and version, printed before you start and rebuildable at /verify/.

The tape proves the draws were not picked for you. It does not prove every sum, which is why each card shows its arithmetic every turn for you to check. Nothing on either card is sealed, so if your chat cannot open links, pasting the whole card plays the full game, and a save code carries the state into a new chat. Every player of an edition gets the same tape, so a second game is a second attempt at the same year or the same life, with your choices the only difference.

Questions about strategy & simulation games

Can I actually lose?

Yes. In The Steward's Year a dial that reaches either end hands the seal back and ends the year; in our simulations, choosing writs at random sees the year out about 2% of the time. Haddow scores how well a whole life stayed balanced: random play averages 35 to 46 against a par of 60, and no life that puts every focus on one strand reaches par.

Are they suitable for children or a classroom?

The Steward's Year is for all ages: harvests, fairs, tolls and two neighbours, with no battles and nobody hurt beyond a charge or a curfew; it suits about ten and up with an adult reading along. Haddow is rated 12+ because it names both parents' deaths, money worries and old age plainly, and ends with the character's own death in one plain sentence. It has no romance, alcohol, drugs or gambling, and if a message sounds like the player rather than the character is going through something, the card tells the AI to step aside from the game.

How long do they take, and can I stop?

The Steward's Year takes thirty to forty-five minutes for sixteen petitions; Haddow takes forty to sixty for at most seventeen turns. Say save at any point for a block that resumes the same year or the same life in a new chat.
