AI Game Cards

Strategy & simulation game prompts for ChatGPT, Claude & Gemini

Updated

Rule a small kingdom for a year or live a whole life, every effect printed and every event from a published dice list. 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.

In a strategy or simulation game played with an AI, every choice's effect is printed on the card and the events come from a dice tape, a list of d20 rolls published with the card, so the assistant looks each outcome up. A one-line status readout, the ledger, carries the whole state from turn to turn.

Can ChatGPT run a strategy game or a life simulator?

Yes, if the rules and the dice are written down first. Asked cold, an assistant 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 shows the draws were not picked for you, and each card prints its arithmetic every turn so you can check the sums as well. 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, and a save code carries the state into a new chat.

Questions about strategy & simulation games

Can I actually lose?

Yes. In The Steward's Year a dial that reaches either end ends the year, and the Council takes the royal seal back; 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, and not 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 30 to 45 minutes for sixteen petitions; Haddow takes 40 to 60 for at most seventeen turns. Say save at any point for a code that resumes the same year or the same life in a new chat.
